AB  - The heavy metals content (HMs) was investigated in 14 different medicinal plants collected
from the three regions in Central Serbia, Zlatar, Sokobanja, and Kopaonik. The concentrations
of Cd, Cr, Ni, Hg and Pb were determined: Cd (<0.03–2.72 mg/kg); Cr (<0.08–12.1 mg/kg); Ni
(<0.08–12.2 mg/kg); Pb (0.6–49.0 mg/kg); the Hg concentration was below the detection limit of
0.06 mg/kg in all samples. The daily intake of HMs due to ingestion of 200 mL of herbal infusion
was in all cases below the recommended limit prescribed by the World Health Organization. The
estimated daily intake values were below the values for the oral reference dose regulated by the U.S.
Environmental Protection Agency (USA EPA). The target hazard quotient and hazard index for Cd,
Cr Ni, and Pb were below 1. Nevertheless, due to the tendency of heavy metals to accumulate in
the organism, attention should be paid to the daily intake of herbal infusion during long-term usage.
Specifically, it is recommended to consume not more than one cup (200 mL) of infusion per day made
from thyme (Mt. Zlatar) and blueberry (Mt. Kopaonik), and not more than two cups per day for
other herbs.

AB  - Pulsed laser ablation in liquids (PLAL) is an approach for the direct synthesis of nanoparticles from the bulk material. In the present work, silver and gold nanoparticles (NPs) were synthesized using the PLAL technique, and obtained water colloid suspensions were characterized by TEM–EDX, ICP-OES, UV–VIS, and DLS methods. On the other hand, Laser-Induced Breakdown Spectroscopy (LIBS) is a well-recognized and versatile analytical technique for the element analysis of solid samples. However, obtaining improved spectral intensity and detection sensitivity are still great challenging tasks, especially for an alternative and cost-effective LIBS setup based on TEA CO2 laser. Considering these demands, this work aimed to investigate a promising approach to signal enhancement based on the deposition of noble NPs on the plastic sample. The effect of NPS on the enhancement of the LIBS signal has been investigated. LIBS experiments were carried out in air at atmospheric pressure and obtained spectra with a high signal-to-background (SBR) ratio. This study shows that signal enhancement can be achieved followed by the lower limits of detection by increasing the ablation amount rate.

AB  - The purpose of this study is to evaluate the feasibility of using the originally developed Laser Induced Breakdown Spectroscopy (LIBS) laboratory setup for the qualitative analysis of human tooth tissues and tooth restorations. Plasma was induced by the infrared TEA (Transversally Excited Atmospheric) CO2 laser in the air under atmospheric pressure. Optical emission spectra with sharp and well-resolved spectral lines and a negligibly low background were obtained. The results of the qualitative analysis showed the presence of various elements in the tooth tissues (P, Ca, and Mg), as well as trace elements within restorations such as Zn, Sn, Cu, Ag, and Hg. The estimated temperatures of plasma for composite, dentin, and amalgam were 21,000 K, 16,200 K, and 13,300 K respectively. The electron density deduced from the Stark-broadening line profiles varies from 8.5 × 1017 cm− 3 for amalgam, 2 × 1018 cm− 3 for composite, and 1.9 × 1018 cm− 3 for dentin. The surface of the tooth tissue was imaged with a scanning electron microscope (SEM), showing that dentin contains pores, cavities and bubbles. The results indicated that the alternative and cost-effective LIBS system can be used as a useful tool for further research on laser-induced plasma in dentistry. These insights are useful in the field of laser dentistry, where lasers are commonly utilized to treat teeth. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Different industrial processes can potentially discharge heavy metals into surface and underground waters. These heavy metals can subsequently accumulate in organisms, posing a significant risk to both the environment and human health. Carbon-based materials such as biochar, carbon nanotubes-based materials, and activated carbon have been extensively researched for their effectiveness in adsorbing heavy metals from aqueous solutions [1]. Today, there is an increased interest in the usage of different low-cost, abundantly available lignocellulosic waste as a precursor for the production of activated carbon material. Activated carbon materials produced from different types of agricultural waste are widely used as adsorbent material for the removal of organic and inorganic pollutants from wastewater. High adsorption capacity is associated with characteristics of the adsorbent such as a large specific surface area, pore structure development, and the presence of different types of functional groups [2]. In this work, activated carbon is produced by the carbonization of sunflower agricultural waste followed by an activation process with potassium hydroxide. Activated carbon samples were characterized by SEM-EDS, BET, FTIR, and XPS. The obtained material has a porous structure with micropores and a large specific surface area, exhibiting a high affinity for the adsorption of lead and copper. Additionally, the main mechanism of lead and copper adsorption by sunflower-derived activated carbon has been successfully predicted.

AB  - Time-integrated optical emission analysis of laser-induced plasma on Teflon is presented. Plasma was induced under atmospheric pressure air using transversely excited atmospheric CO2 laser pulses. Teflon is a C-based polymer that is, among other things, interesting as a substrate for laser-induced breakdown spectroscopy analysis of liquid samples. This study aimed to determine the optimal experimental conditions for obtaining neutral and ionized C spectral lines and C2 and CN molecular band emission suitable for spectrochemical purposes. Evaluation of plasma parameters was done using several spectroscopic techniques. Stark profiles of appropriate C ionic lines were used to determine electron number density. The ratio of the integral intensity of ionic-to-atomic C spectral lines was used to determine the ionization temperature. A spectral emission of C2 Swan and CN violet bands system was used to determine the temperature of the colder, peripheral parts of plasma. We critically analyzed the use of molecular emission bands as a tool for plasma diagnostics and suggested methods for possible improvements.

AB  - A part of the Raša Bay (western Croatia) is an estuary that is fed by the sediment load from the Raša River. The local area
had been affected by the former Raša coal industry. The aim of this study was to determine levels of hazardous trace elements (HTEs) in bottom estuarine sediments, fish and mussels collected from two sites downstream of the Raša River
mouth, and a wild boar’s kidney donated by hunters. The pseudo-total concentrations of 21 HTEs in sediments were
obtained by the X-ray fluorescence (XRF) technique. The results showed that sediment collected closest to the former
Raša coal separation unit Štalije was enriched in V, Sr, Ni, Cu, and Pb. Concentrations of HTEs in flathead grey mullet,
wild blue mussels, and wild boar were obtained by inductively coupled plasma mass spectrometry (ICP-MS). The results
showed that Pb, Cd and Hg in fish and wild mussels were not elevated compared to the Regulation levels of contaminants
in food. Lead and Cd in the kidney of a wild boar exceeded the prescribed maximum values for food. This study warrants
further geochemical investigations of the Raša Bay environment.

AB  - Presented research aimed to develop an alternative approach for the estimation of biosorption capability of sunflower husk. The acid-pretreated sunflower biomass was characterized by scanning electron microscopy combined with energy dispersive X-Ray spectroscopy (SEM-EDX) analysis and Fourier transform infrared (FTIR) spectroscopy. Biosorption efficiency has been evaluated using inductively coupled plasma optical emission spectroscopy (ICP-OES) and laser-induced breakdown spectroscopy (LIBS). The adsorption capacity of the adsorbent was determined as the function of the pH of the solution, the initial concentration of heavy metal solutions, and contact time. The optimal conditions were achieved after 15 min of contact at pH 6, while the percentage of the removal was from 80.0–98.7 %, depending on the element. The results obtained from the kinetic and isotherm studies show that maximum adsorption of ions was quickly reached and followed the pseudo-second-order kinetic model. Real samples were tested and obtained Ni values by LIBS method were 3100±200 and 1240±100 mg kg-1, while estimated values by the ICP-OES were 2995±20 and 1130±10 mg kg-1, respectively. The obtained results prove that LIBS method can be used as a “green alternative” for the evaluation of biosorption efficiency.

AB  - The industrial wastewater produced from various industries contains a significant amount of pollutants among which are heavy metals and represents one of the leading environmental problems facing public health. Conventional wastewater treatment technologies unsuccessfully remove heavy metals completely. As an alternative to various conventional treatment technologies such as ion exchange, chemical precipitation, and electrochemical treatment which have a lot of drawbacks, biosorption is a process characterized by the use of low-cost and abundant agricultural materials with no significant costs and high sorption potentials of biosorbent due to the presence of carboxylic and phenolic groups in lignocellulose matrix. In Serbia, sunflower is the most common oil plant and grows on about 180 000 ha. After industrial processing between 325, 000 and 360, 000 t of sunflower waste ends up in landfills or is used as a source of energy (1). In this work, the sunflower husk was used to remove Ni from aqueous solutions and wastewater sample. The sunflower husk treated with 1% hydrochloric acid was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). In addition, under optimal conditions, the concentration of Ni in wastewater samplewas obtained and compared by two techniques, induced coupled plasma optical emission spectrometry (ICP-OES) as a standard reference method and laser-induced plasma spectroscopy (LIBS) as a non-standard analytical method. The results of these two methods were compared, to investigate the possibility of using laser-induced plasma spectroscopy as a green alternative for the evaluation of biosorption efficiency.

AB  - The research subject of this doctoral dissertation is the spectral emission of laser-induced plasma onmaterials with high carbon content. In particular, plasma was induced by a low-energy (up to 170 mJ)pulsed TEA CO2 laser on graphite, various low-quality coals (lignite), and Teflon. Graphite wasselected as a technologically important material with numerous applications, including laser synthesisof diamond coatings and graphite nanoparticles. There is a strong interest in developing fast methodsfor the elemental analysis of lignite in order to optimize the combustion process in thermal powerplants. Teflon was chosen as an example of a polymer that is, among other things, interesting as asubstrate for LIBS analysis of liquid samples.The research aimed to determine the most favorable experimental conditions for obtaining plasmawith optimal emission of atomic and ionic lines of elements and molecular bands (C2 and CN) suitablefor spectrochemical purposes. The applicability of the LIBS based on IR laser for elemental analysisof coal was demonstrated; the obtained precision, the dynamic range of the calibration curve, anddetection limit values confirm the potential of this method for rapid quantitative coal analysis.The plasma parameters were obtained using different optical spectroscopy diagnostic methods. Theelectron number density was determined from Stark profiles of suitable lines, while plasmatemperature was determined from the ratio of integral intensities of spectral lines. Special attentionwas paid to optimizing the emission of molecular bands and their application for determining thetemperature of colder, peripheral parts of the plasma. The applied diagnostic methods were criticallyanalyzed, and possible improvements were proposed

AB  - U ovom radu ispitivana je mogućnost primene nanočestica ZnO za fotokatalitičku degradaciju boje bromkrezol zeleno i komercijalno dostupne boje za bojenje tekstila. Vodena suspenzija nanočestica ZnO dobijena je laserskom ablacijom [1]. Koncentracija nanočestica određena je metodom ISP-OES. Rastvori boje sa različitim količinama nanočestica izlagani su dejstvu UVC zračenja i to u intervalima od 5 minuta u ukupnom trajanju od sat vremena. Degradacija boja u toku ozračivanja utvrđena je merenjem apsorbancije UV-VIS spektrometrijom pre, tokom i nakon ozračivanja. Preliminarni rezultati potvrdili su početnu pretpostavku da se nanočestice dobijene laserskom sintezom mogu koristiti za degradaciju boja.
AB  - In this paper, the possible use of ZnO nanoparticles for photocatalytic degradation of dyes, in particular bromocresol green and commercial textile dyes, was examined. А water suspension of ZnO nanoparticles was prepared by laser ablation. Concentration of nanoparticles was measured by ICP-OES technique. Dyes solutions with different amounts of nanoparticles were exposed to UVC irradiation at 5 minute intervals for a total period of 1 hour. Degradation of dyes during irradiation was determined by UV-VIS spectroscopy by measuring solution absorbance before, during, and after exposition. Preliminary results confirmed the initial assumption that laser synthesized nanoparticles could be used for dye degradation.

AB  - In the past two decades, with recent advances in laser technology, Laser-Induced Breakdown Spectroscopy (LIBS) has become a more and more popular analytical method for the analysis of any type of samples. Some exclusive properties such as rapid, multi-element analysis of any kind of material, non-contact and almost non-destructive, independent of sample conductivity, geometry and size make this method superior to the other standard optical emission techniques. In this work, we will demonstrate the possibility of using a cost-effective alternative to commercial LIBS systems, the TEA CO2 laser-based LIBS setup for analysis of environmental-related samples: for direct analysis of solid samples and indirect analysis of liquid samples. Finally, our developed method doesn’t use any hazardous reagents and solvents and maximizes safety for operators and the environment, which creates it in full accordance with the principles of green analytical chemistry.

AB  - This paper evaluates the possibilities of the original LIBS (Laser Induced Breakdown Spectroscopes) laboratory setup for the elementary analysis of human tooth tissues and tooth restorations. For that reason, samples of the teeth restored with amalgam and composite fillings were analyzed. In addition, the possibility of heavy metal diffusion from restoring materials into healthy tooth tissues was also examined. Plasma was induced by the TEA CO2 laser in the air under atmospheric pressure. Optical emission spectra with sharp and well-decomposed spectral lines and a negligibly low background were obtained. The results of the elemental analysis showed the presence of various trace elements in the tooth tissues (P, Ca, Mg) as well as within restorations such as Zn, Cu, Ag, Hg. The analysis also showed that cement successfully blocked diffusion from restoring materials (amalgam and composite) into the dentine below. Obtained preliminary results led to the conclusion that this alternative and cost-effective LIBS system can find application as a useful tool for further research on laser-induced plasma in dentistry

In the present study, we tested the effect of the duration, intensity-time profile and wavelength of the laser pulses on the performance of NELIBS analysis of solid samples. Three different laser sources (a transversely excited atmospheric CO2 laser, a fiber laser and a Nd:YAG laser) with three wavelengths (266 nm, 1064 nm and 10.6 µm) and controllable waveforms were used in the experiments, in which we studied the signal enhancement factor and the time evolution of plasma characteristics. Different size silver, gold and binary NPs were prepared for the experiments using chemical and physical particle generation methodologies and applied to the samples using the droplet deposition method. The NELIBS signal enhancement was studied for several trace elements in steel, aluminum and plastic samples.

AB  - Novel methods of cancer therapy are constantly being investigated since the current approach heavily relies on the use of non-specific and toxic chemotherapy agents. Ideally, a drug used for cancer therapy would specifically target tumor sites or rather bind specifically with cancer cells. The way to achieve this is by targeting cancer cell specific receptors or receptors present in abnormally high counts at the surface. Rapid proliferation of cancer cells is fueled by large amounts of energy that is in turn produced by abnormal glucose uptake. Because of this high energy/glucose demand, cancer cells exhibit an abnormally high glucose receptor (GLUTs) count on their surface, compared to normal, healthy cells. We have utilized this glucose dependency to create glucose modified liposomes (Glucosomes) that are specifically bound by cancer cells. Glucosomes can be used to transport different substances, either hydrophilic or hydrophobic, and can therefore deliver any type of drug to cancer cells, increasing its efficiency. Another important aspect to consider is the controlled release of the drug being transported in order to maximize therapeutic efficiency. Controlled release can be achieved by utilizing different internal or external influences. In our study, we have used standard Fe3O4 magnetic nanoparticles to load glucosomes and induce their controlled opening via an external magnetic field. By applying an external magnetic field, the magnetic nanoparticles start heating up and transferring this thermal energy to the surrounding lipid bilayer, causing its perturbation and opening of the glucosome. Our study has found that controlled release can be achieved with high efficiency while the chemical stability of the Fe3O4 nanoparticles stays practically intact. Using EPR spectroscopy, we have shown that Fe3O4 nanoparticles remain trapped within the lipid bilayer and are essentially protected from oxidation that would diminish their magnetic properties. Since magnetic Fe3O4 nanoparticles are lodged well within the lipid bilayer no thermal damage can be caused to the drug being transported within the glucosome bilayer, making this a viable controlled release cancer targeting drug delivery system.

abstract = "Novel methods of cancer therapy are constantly being investigated since the current approach heavily relies on the use of non-specific and toxic chemotherapy agents. Ideally, a drug used for cancer therapy would specifically target tumor sites or rather bind specifically with cancer cells. The way to achieve this is by targeting cancer cell specific receptors or receptors present in abnormally high counts at the surface. Rapid proliferation of cancer cells is fueled by large amounts of energy that is in turn produced by abnormal glucose uptake. Because of this high energy/glucose demand, cancer cells exhibit an abnormally high glucose receptor (GLUTs) count on their surface, compared to normal, healthy cells. We have utilized this glucose dependency to create glucose modified liposomes (Glucosomes) that are specifically bound by cancer cells. Glucosomes can be used to transport different substances, either hydrophilic or hydrophobic, and can therefore deliver any type of drug to cancer cells, increasing its efficiency. Another important aspect to consider is the controlled release of the drug being transported in order to maximize therapeutic efficiency. Controlled release can be achieved by utilizing different internal or external influences. In our study, we have used standard Fe3O4 magnetic nanoparticles to load glucosomes and induce their controlled opening via an external magnetic field. By applying an external magnetic field, the magnetic nanoparticles start heating up and transferring this thermal energy to the surrounding lipid bilayer, causing its perturbation and opening of the glucosome.

AB  - This work presents a study of the applicability of laser-induced breakdown spectroscopy based on infrared transversally excited atmospheric CO2 pulsed laser for quantitative analysis of main inorganic elements in lignite coals. Calibration standards were prepared by mixing and pelleting an appropriate amount of rock reference material and graphite. Time-integrated spatially resolved measurements of analyte spectra of standard samples were used to construct univariate calibration curves of Al, Si, Ca, Fe and Mg. The spectral intensities of analytical lines were normalized by the carbon spectral line to compensate for the shot-to-shot fluctuation of plasma parameters. The obtained curves of growth have good linearity in a wide range of concentrations (up to 1% for Al and 3% for Si). Correlation coefficients were in the range of 0.955–0.993, depending on the element. Measured limits of detection (from 2.4 to 25 ppm for analyzed metals and 61 ppm for Si) are low enough to control the coal combustion process in power plants. The Stark-broadening and the Boltzmann plot method were used to determine apparent values of excitation temperatures and electron number densities. A relatively small but measurable influence of the concentration of metal elements on the plasma parameters was observed, which should be considered in quantitative analysis of coal samples with higher inorganic elements content.

AB  - All remediation pathways in aqueous solutions come down to three dominant ones - physical, chemical, and combinations thereof. Materials proposed for adsorption and oxidative degradation can induce positive or negative effects on cells compared to the pollutants themselves. Present research deals with the effects different methods for pesticide remediation have and how they impact cytotoxicity. With this particular intention, Fe-modified zeolites (obtained via citrate/oxalate complexes) of three zeotypes (MFI, BEA and FAU) were prepared and tested as adsorbents and Fenton catalysts for the removal of the acetamiprid pesticide. The materials are characterized by AFM, FTIR spectroscopy and ICP-OES. A different effect of the zeolite framework and modification route was found among the samples, which leads to pronounced adsorption (FAU), efficient Fenton degradation (MFI) or synergistic effect of both mechanisms (BEA). The cytotoxic effects of acetamiprid in the presence of zeolites, in pristine and modified forms, were tested on the MRC-5 human fibroblast cell line. A complete survey of the toxicity effect behind different pesticide removal methods is presented. Since neither adsorption nor catalytic degradation is the best option for pesticide removal, the focus is shifted to a combination of these methods, which proved to be optimal for pesticide toxicity reduction.

AB  - Micro–sized multivesicular liposomes were prepared, radiolabeled with 177Lu, and tested in vitro and in vivo to evaluate the potential of 177Lu–labeled micro liposomes in radiosynoviorthesis (RSO) therapy. A standard reverse–phase procedure of liposome preparation with a lipid mixture of DPPC: CHOL (80:20%) was used for the synthesis. TEM and fluorescence microscopy imaging were performed to determine the size, shape, and structure of the prepared liposomes. Both measurements are in good agreement while TEM micrographs additionally indicate to a large multivesicular inner structure of prepared liposomes. A simple and straightforward procedure was used for liposome radiolabeling with 177Lu, a well–known and commonly used radionuclide in radiotherapy with favorable properties, that can be exploited in RSO therapy. Radiolabeled 177Lu–liposomes were tested in vitro for stability and then injected into the knee joints of Wistar rats where liposome in vivo behavior was followed up to 30 days post injection. Results from both ex vivo biodistribution and in vivo imaging studies presented a high stability and retention (>94 %ID) of 177Lu–micro liposomes in the synovial liquid for the entire observation period. Leakage of free 177Lu or 177Lu–liposomes from the synovial fluid has not been detected, indicating to a possible application of 177Lu–liposomes in radiosynoviorthesis (RSO) therapy.

AB  - Biochar produced by pyrolysis of plum and fig pomace at 500 C were characterized and investigated as adsorbents for the removal of heavy metal ions from aqueous solution. Plum and fig pomace are formed after fermentation of this fruit which is used for the preparation of brandy. The brandy industry generates huge amounts of pomace as industrial waste, so pyrolysis as thermochemical technologies was used for organic agro-industrial waste treatment. Plum and fig pomace before and after pyrolysis was characterized using proximate, inorganic and elemental analysis, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Biochar has a carbon matrix with a high degree of porosity and large surface area, suggesting that it can be used as a surface adsorbent and thus have a significant role in controlling environmental contaminants. The surface modification by gamma irradiation was done to enhance the adsorption capacity of biochar. The heavy metals contents in aqueous solution were analyzed using ICP-OES. The adsorption capacity was estimated using the Langmuir and Freundlich model. The results of this work suggest that pyrolysis and irradiation of biomass is a promising way to produce efficient heavy metal sorbents for waste-water treatment.

AB  - Taking into account that powder paprika is among spices that are often subjected to adulteration, the aim of this work was the analysis of twelve different branded powder paprika collected from Serbian markets. The total content of ash and sand was determined, and results have shown that values ranged from 5.40 to 7.80% and from 0.77 to 2.23%, respectively. The inductively coupled plasma optical emission spectrometry method was used for the quantification of 16 elements (Cd, Fe, Ni, Pb, Be, Zn, Cu, Mo, Ti, Sr, Ca, Al, B, Cr, Mg and Mn). Among all determined elements, the most abundant was Ca, followed by Mg and Fe. UV spectroscopy was used as a screening method to determine the adulteration level with Sudan I dye of spice paprika powders. It was found that none of the investigated samples contain Sudan I dye. Furthermore, multivariate classifications models were created for discrimination based on adulterant and powder paprika content in sample mixtures.

AB  - X-ray Fluorescence (XRF) is the most commonly used non-destructive method offering the user a portable handheld analyzer that delivers fast, accurate results. On the other hand, in the past two decades, with recent advances in laser technology,laser-induced breakdown spectroscopy (LIBS) becomes a more and more popular analytical method for the analysis of solid samples. The ability to provide a fast and multielement analytical response directly from a solid sample makes both LIBS and XRF very versatile tools for soil analysis [1]. Both methods have their advantages, however, in certain circumstances, one is better to use over the other. This paper focuses on the analytical capability of both methods for soil quality management. The main LIBS advantage against XRF is that it can be used for detection of all elements of the Periodic Table, including light elements (C, N, O, S) important for estimation of soil quality [2]. For this paper, 2 samples of soil were used. A real sample was collected in the INS Vinča and certified reference material Metals in Soil obtained from Sigma Aldrich were used for these experiments. A real soil sample was dried at 70℃, homogenized, and sieved using a 100 mesh sieve. Single element calibration standards of Cu, Hg, Ni, Pb, and Cd from J.T. Baker were used for standard addition samples preparation [3]. To homogenized sample portions of fixed mass (5 g) varying amounts of certified standard analyte solutions are added, and the mixture is diluted with 20 ml deionized water. Mixtures were homogenized and dried at 70℃ overnight. The obtained powdered materials were used for the preparation of pressed pellets, including the CRM sample. All samples were analyzed by a unique TEA CO2 based LIBS setup developed in INS Vinča and commercially available Niton XL3 handheld XRF analyzer, Thermo Fischer Scientific. The precision and accuracy of the LIBS method were evaluated and compared to those obtained by XRF. The preliminary results showed that limits of detection for most of the investigated elements are comparable or better than those obtained with XRF.

AB  - Resultsof Electrochemical Impedance Spectroscopy (EIS) are reported for lithium-niobium-titanium-oxide (LNTO) ceramics synthesized by a solid-state reaction method with two functional additives (MoO3 or ZnO) in the temperature range 323 K - 573 K and frequencies between 10−1 Hz and 107 Hz. Scanning electron microscopy (SEM) reveals a textured morphology of rod and plate-like particles that are typical for M-phase LNTO materials, while X-ray diffraction (XRD) analysis confirms the formation of an M-phase member compound with an approximate structure of Li7Nb3Ti5O21. Complex impedance analysis indicates that its overall electrical resistivity behavior depends mostly on the grain boundary processes. EIS analysis shows a negative temperature coefficient of resistance behavior (NTCR) in a defined temperature range in two LNTOs and thermal activation of the conduction mechanisms. The low dielectric constants of 5.5 and 12.1 at 1 MHz were found for the first and second LNTOs, respectively. Complimentary Raman spectroscopic measurements, despite very large crystallographic unit cell of LNTO, reveal only a small number of lines, which is the consequence of a “molecular” nature of materials.
