AB  - Archeological mortars are often composed of highly inhomogeneous materials and detailed analysis in most cases can be quite difficult. In this work, a Laser-Induced Breakdown Spectroscopy (LIBS) equipment with microscopic-scale spatial resolution was used to image the distribution of elements on real archeological samples of mortars and construction material used in the foundations of the Smederevo Fortress (Republic of Serbia). A double-pulse Nd:YAG at the fundamental wavelength (λ = 1064 nm) and a CCD spectrometer coupled with a commercial microscope were used to generate the plasma and acquire the LIBS spectra. Thanks to the combined use of an unsupervised clustering algorithm and the calibration-free procedure, the results obtained show that it is possible to obtain a good discrimination between materials of different composition, allowing a quick classification for further mineral-petrographic investigations.

AB  - The effects of picosecond Nd:YAG laser irradiation on chemical and morphological surface characteristics of the commercially pure titanium and Ti-13Nb-13Zr alloy in air and argon atmospheres were studied under different laser output energy values. During the interaction of laser irradiation with the investigated materials, a part of the energy was absorbed on the target surface, influencing surface modifications. Laser beam interaction with the target surface resulted in various morphological alterations, resulting in crater formation and the presence of microcracks and hydrodynamic structures. Moreover, different chemical changes were induced on the target materials' surfaces, resulting in the titanium oxide formation in the irradiation-affected area and consequently increasing the irradiation energy absorption. Given the high energy absorption at the site of interaction, the dimensions of the surface damaged area increased. Consequently, surface roughness increased. The appearance of surface oxides also led to the increased material hardness in the surface-modified area. Observed chemical and morphological changes were pronounced after laser irradiation of the Ti-13Nb-13Zr alloy surface.

AB  - In the present study surface alterations of the high pressure torsion (HPT)-deformed Ti[sbnd]45Nb (mass%) alloy induced by laser irradiation treatment are presented. The alloy was irradiated in air, argon, and nitrogen atmosphere using the Nd:YAG laser. Laser-induced surface modifications were analyzed by field-emission scanning electron microscopy (FE-SEM), energy-dispersive spectroscopy (EDS), profilometric analysis, and Vickers microhardness measurements. Alloy irradiation under a low laser output energy and a low number of accumulated pulses resulted in the formation of shallow surface craters. An increase of these irradiation parameters caused the appearance of more pronounced surface craters with microcracks and hydrodynamic effects in the form of wave-like structures, ripples, and solidified droplets and consequently caused an increase in the surface roughness. The highest value of the surface roughness of 3.062 μm was attained during the alloy irradiation in argon atmosphere under 15 mJ with 150 accumulated pulses. Interaction of the laser beam with the alloy surface was accompanied by plasma formation and surface ablation due to the irradiation energy absorption. The maximal ablated target material volumes of 5.5 × 1014 nm3 and 2.6 × 1014 nm3 were observed after the irradiation under 15 mJ with 150 accumulated pulses in argon and air atmosphere, respectively. Moreover, attainment of high temperatures at the alloy surface induced its chemical composition alterations. Formation of mixed Ti- and Nb-oxide surface film and absence of nitride particles at the alloy surface was detected irrespective of the irradiation atmosphere. Irradiation in air resulted in the appearance of the most pronounced surface oxide layer with the highest microhardness value which can in great merit influence an increase of the alloy bio-integration abilities and its tribo-corrosion resistance. © 2021 Elsevier B.V.

AB  - Unused/expired pharmaceuticals can be regarded as a source of valuable compounds. Valorization of active pharmaceutical ingredients (APIs) from pharmaceutical waste, as an alternative to widely adopted treatment by incineration, is a big challenge in terms of designing green, efficient, scalable and sustainable separation methods. Concerning these demands, this work aimed to investigate and propose new integrated extraction technology based on aqueous biphasic systems (ABS) with eco-friendly components namely, poloxamer (Pluronic PE 6200) and one of two salts (sodium citrate, cholinium dihydrogenphosphate) or ionic liquid (1-butyl-3-methylimidazolium chloride). Liquid-liquid equilibria of each ABS were determined at room temperature followed by partition experiments in the biphasic medium to evaluate the most favorable systems for APIs extraction (acetaminophen and caffeine from one commercial product, and theophylline from the other). The finely designed ABSs were then employed to separate APIs from pharmaceutical solids and fractionate them. The results show that citrate-based ABS induces the strongest salting-out effect leading to extraction of all APIs to the Pluronic-rich phase with high recovery efficiencies between 79.4 and 97.90%; insoluble compounds were removed as residues while hydrophilic excipients remained in the citrate-rich aqueous phase. Ionic liquid/PL6200-based ABS was further applied to fractionate acetaminophen and caffeine toward opposite phases. These results underpin the viability and adjustability of PL6200-based ABSs within an integrated process, by a deftly selected salting-out agent, as a sustainable and efficient alternative platform with the great potential to be implemented on a larger scale.

AB  - The application of an alternative laser-induced breakdown spectroscopy (LIBS) method based on transversely excited atmospheric (TEA) CO2 laser was investigated for the first time for estimating the hardness of metallic materials. The human eye-safe (TEA) CO2 laser, operating at 10.6 µm, was used for plasma generation. The LIBS spectra were recorded by employing a cost-effective CCD camera for the time-integrated and spatial resolved measurements. The cast iron and aluminum alloys samples with different hardness have been tested. The ratio between the magnesium ionic and neutral lines in LIBS spectra was applied for estimating the material hardness. In addition, the hardness of all samples included in this study was determined using the conventional method for material hardness determination, i.e. Vickers hardness test. The linear dependence of magnesium lines intensity ratio on the sample’s hardness was obtained for both kinds of materials. Profilometric measurements were used to verify that the newly-introduced method is almost nondestructive for the investigated metals. The results obtained in the present work confirmed the potential of using this original LIBS system not only for the fast elemental analysis but also for the direct estimation of the hardness of metals and alloys. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.

AB  - This study was carried out to examine the applicability of original laser-induced breakdown spectroscopy (LIBS) setup for determination of the surface hardness of lead glass as a function of its chemical composition. For this purpose, a set of five lead glass samples with different amount of ZrO2 was prepared. The LIBS measurements were carried out using TEA CO2 laser in the air at atmospheric pressure and without sample preparation. A ratio of the intensity between the Zr(II) 355.66 nm and Zr(I) 360.12 nm emission lines has been used to examine the hardness of the material. In addition, the surface hardness of glass samples was determined by Vickers’s indentation tests.

abstract = "This study was carried out to examine the applicability of original laser-induced breakdown spectroscopy (LIBS) setup for determination of the surface hardness of lead glass as a function of its chemical composition. For this purpose, a set of five lead glass samples with different amount of ZrO2 was prepared. The LIBS measurements were carried out using TEA CO2 laser in the air at atmospheric pressure and without sample preparation. A ratio of the intensity between the Zr(II) 355.66 nm and Zr(I) 360.12 nm emission lines has been used to examine the hardness of the material. In addition, the surface hardness of glass samples was determined by Vickers’s indentation tests.

AB  - Time-integrated optical emission spectroscopy was applied for the analysis of emission spectra, and determination of electron densities and excitation temperatures of basalt plasma induced by 10.6 micron laser radiation. The plasma was studied in air, argon and carbon dioxide, under pressure of 10, 50, and 100 mbar. The plasma emission intensity was found to be strongly dependent on the nature of the ambient gas and its pressure. The highest emission intensities and signal to noise ratios were obtained in argon. Depending on the composition and pressure of the surrounding atmosphere, the values of plasma temperature varied between 14,400 K (air at 10 mbar) and 17,100 K (carbon dioxide at 100 mbar). Similarly, the electron number density varied between 3 × 1016 cm−3 (10 mbar air) and 1.6 × 1017 cm−3 (100 mbar CO2). The observed behavior was correlated with the properties of the studied gases, in particular, their mass, thermal conductivity and ionization energy, and the role of the ambient gas in controlling the efficiency of laser-target coupling, laser-plasma interaction and plasma shielding. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Suitability of bentonite clay modified with sodium carboxymethyl cellulose (Na-CMC) for the removal of arsenic(III) ions from aqueous solution was tested in batch adsorption studies and complemented by theoretical modeling with Langmuir, Freundlich and Temkin isotherm models. The effects of various factors, such as the initial adsorbate concentrations, pH, and temperature of the solutions were investigated in series of experiments. FTIR analysis was used to detect functional groups typical for cellulose and bentonite. Scanning electron microscope was used to analyze the surface morphology of the composites. It was established that the removal process was fast in the beginning and adsorption equilibrium was attained in around 20 minutes with good fittings to both Langmuir and Freundlich model. Maximum adsorption capacity (Q max ) obtained from experiments was 9.4 mg/g. No influence of solution pH and temperature on the sorption was noticed. The series of conducted experiments showed that synthesized composites are suitable for the removal of arsenic from wastewaters by adsorption as efficient and low-cost technique. © 2019, ALÖKI Kft., Budapest, Hungary.

AB  - In this study, analytical capability of Laser Induced Breakdown Spectroscopy (LIBS) system based on Transversely Excited Atmospheric pressure (TEA) CO2 laser for determination of elemental composition of tea samples was demonstrated. Analysis of LIBS spectra indicated emission lines attributed to the elements Fe, Mg, Cu, Ca, Al, Mn, Ba, P, K and Sr. For quantitative analysis of Mn and Ba, a standard addition method was employed. Linear calibration curves with regression coefficients exceeding 0.95 were obtained. The accuracy of LIBS results was confirmed by inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis. Calculated recoveries for Ba and Mn were 99.7 and 102.3%, respectively. The results presented confirm the suitability of the proposed LIBS setup for rapid quantitative analysis of tea, while at the same time simplifying the overall analytical procedure. This approach can be easily used as a helpful analytical tool for food quality and safety control. (C) 2017 Elsevier B.V. All rights reserved.

AB  - In present paper, the influence of the initial pH and concentration of Pb2+ on its adsorption by the natural (NZA) and Fe(III)-modified zeolite-alginate beads (FeA) was studied. Results showed that modification of the starting materials have a positive effect on their adsorption capacities (102 and 136 mg/g for the NZA and FeA, respectively). After encapsulation, the mechanism of lead adsorption by both adsorbents was changed and ion exchange dominates. The best adsorption was achieved for initial pH GT 3.8. Cation exchange capacity, structural properties, and hydrophobicity of samples were also determined, and the presence of the alginate has no significant influence on investigated properties of samples. Experiments on wastewater from tailings of lead and zinc mine Grot, Serbia, showed that after treatment with both adsorbents, the content of the most abundant heavy metals (Pb, Zn, Hg, and Mn) significantly decreased.

AB  - In the presented paper, activated carbons were prepared from fructose and glucose, and activating agents (KOH, NaOH, LiOH) by hydrothermal treatment (HTC) treatment. After preparation, samples were characterized in details. Different techniques were used: x-ray powder diffraction analysis, Raman spectral analysis, elemental analysis, and determination of textural and morphological properties. Obtained results showed dependence of investigated properties and the nature of precursors (glucose or fructose) as well as the type of hydroxides used as activating agents. After characterization, samples were tested as materials for heavy metals (Pb2+, Cd2+and Zn2+) and methylene blue removal. Also, adsorption experiments were performed on wastewaters taken from tailings of the lead and zinc mine and kinetic of the methylene blue removal was studied. The factors which distinguished the KOH activated samples were high yield (~14%), content of organic carbon (63–74%), porosity and specific surface area (SBET~700–1360 m2/g), a low degree of the crystal phase, indications that potassium ions may be included in heavy metals removal, good removal of the heavy metal ions (~47–59 mg/g for Pb2+, ~21–27 mg/g for Cd2+and ~6–10 mg/g for Zn2+) and fast (~10–30 min) and good methylene blue (~60–200 mg/g) removal.

AB  - We present a study of the plasma generated by transversely excited atmospheric (TEA) CO2 laser irradiation of a basalt sample. The plasma was induced in air at atmospheric pressure. The same sample was also analyzed using a commercial LIBS system based on Nd:YAG laser and time-gated detection. The main plasma parameters, temperature, and electron number density were determined and analytical capabilities of the two systems compared. Despite differences in laser wavelength, pulse duration, applied fluence, and signal detection scheme, the two systems are comparable in terms of element detectability and limits of detection. In both cases, all elements usually present in geological samples were identified. The estimated limits of detection for most elements were below 100 ppm, while for Cu, Cr, and Sr they were around or below 10 ppm.

AB  - The analytical capability of laser-produced plasma for the analysis of low alloying elements in cast iron samples has been investigated. The plasma was induced by irradiation of a sample in air at atmospheric pressure using an infrared CO2 laser. Emission spectra were recorded by time-integrated spatially-resolved measurement technique. A set of ten cast iron samples in a powder or particulate form were provided by BAM (Bundesanstalt fur Material Forschung und Prufung, Deutschland), seven of which were used for calibration, and three were treated as unknowns. Linear calibration curves were obtained for copper, chromium, and nickel, with correlation coefficients above 0.99. Precision and accuracy of the LIBS method was evaluated and compared to those obtained by the inductively coupled plasma (ICP) analysis of the same samples. Detection limits for Cu, Cr and Ni were close to those reported in the literature for other comparable iron-based alloys obtained using different LIBS systems. Analytical figures of merit of the studied LIBS system may be considered as satisfying, especially in the light of other advantages of the method, like cost effective and fast analysis with no sample preparation, and with a possibility for real-time on-site analysis.

AB  - The aim of this study was to develop a simple laser induced breakdown spectroscopy (LIBS) method for quantitative elemental analysis of powdered biological materials based on laboratory prepared calibration samples. The analysis was done using ungated single pulse LIBS in ambient air at atmospheric pressure. Transversely-Excited Atmospheric pressure (TEA) CO2 laser was used as an energy source for plasma generation on samples. The material used for the analysis was a blue-green alga Spirulina, widely used in food and pharmaceutical industries and also in a few biotechnological applications. To demonstrate the analytical potential of this particular LIBS system the obtained spectra were compared to the spectra obtained using a commercial LIBS system based on pulsed Nd:YAG laser. A single sample of known concentration was used to estimate detection limits for Ba, Ca, Fe, Mg, Mn, Si and Sr and compare detection power of these two LIES systems. TEA CO2 laser based LIES was also applied for quantitative analysis of the elements in powder Spirulina samples. Analytical curves for Ba, Fe, Mg, Mn and Sr were constructed using laboratory produced matrix-matched calibration samples. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used as the reference technique for elemental quantification, and reasonably well agreement between ICP and LIBS data was obtained. Results confirm that, in respect to its sensitivity and precision, TEA CO2 laser based LIBS can be successfully applied for quantitative analysis of macro and micro-elements in algal samples. The fact that nearly all classes of materials can be prepared as powders implies that the proposed method could be easily extended to a quantitative analysis of different kinds of materials, organic, biological or inorganic.

AB  - The applicability of nanosecond infrared Transversely Excited Atmospheric (TEA) CO2 laser induced plasma for spectrochemical analysis of aluminum alloys was investigated. The plasma was generated by focusing a pulsed TEA CO2 laser that emits at 10.6 mu m on the Al target in ambient air at atmospheric pressure. The temporal profile of the laser pulse is composed of a 100 ns peak followed by a slowly decaying tail of about 2 mu s. The output pulse energy was approximately 160 mJ, thus the peak output power was estimated to be around 1.6 MW. Time-Integrated Space-Resolved Laser Induced Breakdown Spectroscopy (TISR-LIBS) was employed to obtain the emission spectra. The maximum intensity of emission, with sharp and well resolved spectral lines that were almost free of the background continuum, was obtained from plasma region 2 mm from the target surface. Linear calibration curves for Mg, Cr, Cu and Fe were obtained using aluminum alloy spectrochemical standards. The limits of detection for the investigated elements were in the 2-73 ppm range. Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) was used as a reference technique to estimate the accuracy of LIBS determination by use of control samples with known compositions. Comparison of the obtained results with those available in the literature confirms that LIBS system based on TEA CO2 laser, in combination with TISR spectral measurements, can be successfully applied to qualitative and quantitative determinations of minor elements in aluminum based alloys.

AB  - Interaction of a TEA CO2 laser with a titanium implant in vacuum (air pressure 0.1 mbar) was studied. The laser operates at 10: 6 mu m with pulse duration of 100 ns (FWHM). The surface alternations were studied at the moderate laser beam energy density/fluence of 52 J/cm(2). The energy absorbed from the TEA CO2 laser beam was partially converted to thermal energy, which generated a series of effects such as melting, vaporization of the molten material, shock waves, etc. The following titanium implant surface changes and phenomena were observed: (1) creation of superficial damage which takes crater-shaped form at a higher number of accumulated laser pulses. Maximal depth of the damage was 9 mu m for 500 laser pulses. The damage cross-section had a conical form; (2) melt pools, inside the damage region, especially prominent for higher number of accumulated pulses; (3) preservation of chemical surface composition in central, and changes at the peripheral region, and (4) occurrence of plasma in front of the implant. The results have shown that under the applied experimental conditions, TEA CO2 laser can effectively be applied for enhancing the titanium implant roughness and creation of surface chemical changes. The appearance of plasma in front of the implant offers a sterilizing effect, facilitating contaminant-free conditions.

AB  - The present work studies the possibility of using pulsed Transversely Excited Atmospheric (TEA) carbon dioxide laser as an energy source for laser-induced breakdown spectroscopy (LIBS) analysis of rocks under simulated Martian atmospheric conditions. Irradiation of a basaltic rock sample with the laser intensity of 56 MW cm(-2), in carbon-dioxide gas at a pressure of 9 mbar, created target plasma with favorable conditions for excitation of all elements usually found in geological samples. Detection limits of minor constituents (Ba, Cr, Cu, Mn, Ni, Sr, V, and Zr) were in the 3 ppm-30 ppm range depending on the element. The precision varied between 5% and 25% for concentration levels of 1% to 10 ppm, respectively. Generally, the proposed relatively simple TEA CO2 laser-LIBS system provides good sensitivity for geological studies under reduced CO2 pressure. (C) 2016 Elsevier B.V. All rights reserved.

AB  - This  paper  gives  an  overview  of  analytical  capabilities  of  the  laser  induced breakdown  spectroscopy  (LIBS)  system,  based  on  Transversely-Excited Atmospheric  pressure  (TEA)  CO2laser,  and  time-integrated,  spatially-resolved  detection,  for  the  analysis  of  solid  materials.  The  developed  LIBS system  is  unique,  and  differs  from  the  commonly  used  systems  in  two respects.  The  first  one  is  the  laser  used  as  an  energy  source  for  plasma generation,  and  the  second  one  is  the  applied  non-gated  detection  scheme. Various   types   of   materials   were   analyzed,   from   metals   to   biological samples, under different experimental conditions. The obtained results were critically    evaluated    and    compared    to    the    results    obtained    using commercially  available  LIBS  that  comprises  Nd:YAG  laser  and  time-gated detection.It was concluded that when it comes to detectability, precision and sensitivity,  this  simple  and  cost  effective  LIBS  system  may  be  regarded highly competitive to standard LIBS systems.

AB  - Spatially resolved, time-integrated optical emission spectroscopy was applied for investigation of copper plasma produced by a nanosecond infrared (IR) transversely excited atmospheric (TEA) CO2 laser, operating at 10.6 gm. The effect of surrounding air pressure, in the pressure range 0.1 to 1013 mbar, on plasma formation and its characteristics was investigated. A linear dependence of intensity threshold for plasma formation on logarithm of air pressure was found. Lowering of the air pressure reduces the extent of gas breakdown, enabling better laser-target coupling and thus increases ablation. Optimum air pressure for target plasma formation was 0.1 mbar. Under that pressure, the induced plasma consisted of two clearly distinguished and spatially separated regions. The maximum intensity of emission, with sharp and well-resolved spectral lines and negligibly low background emission, was obtained from a plasma zone 8 mm from the target surface. The estimated excitation temperature in this zone was around 7000 K. The favorable signal to background ratio obtained in this plasma region indicates possible analytical application of TEA CO2 laser produced copper plasma. Detection limits of trace elements present in the Cu sample were on the order of 10 ppm (parts per million). Time-resolved measurements of spatially selected plasma zones were used to find a correlation between the observed spatial position and time delay.

AB  - The applicability of a nanosecond infrared (IR) transversely excited atmospheric (TEA) CO2 laser, operating at 10.6 mu m and 100 ns pulse length (initial spike), induced plasma under reduced air pressure for spectrochemical analysis of bronze and brass samples was investigated. The plasma consisted of two clearly distinguished and spatially separated regions and expanded to a distance of about 10 mm from the surface. The elemental composition of the samples was determined using a time-integrated space-resolved laser-induced plasma spectroscopic (TISR-LIPS) technique. Sharp and well-resolved spectral lines mostly atomic, and negligibly low background emission, were obtained from a plasma region 7 mm from the target surface. Good signal to background and signal to noise ratios were obtained. The estimated detection limits for the trace elements Mg, Fe, Al and Ca were in the order of 10 ppm in bronze and around 50 ppm in brass. Damage on the investigated samples induced by TEA CO2 laser radiation was negligible.

AB  - Optical emission spectroscopy was applied for investigation of copper plasma induced by a nanosecond transversely excited atmospheric CO2 laser, operating at 10.6 mu m. The effect of the background gas (air, Ar, He and N-2) and pressure (1-25 mbar) on plasma formation was examined. The plasma shielding effect was more pronounced for background gases with lower ionization potential than for He. The increase of He pressure from 1 to 25 mbar resulted in fivefold increase of Cu atomic line intensity.

AB  - Interaction of a transversely excited atmospheric (TEA) CO2 laser with rough copper surface, at reduced air pressure, was studied. Optical pulse duration of the laser employed was similar to 2 mu s, with the initial spike FWHM of similar to 100 ns. Laser energy density of similar to 32 J/cm(2) (intensity similar to 10(8) W/cm(2)) was above the plasma ignition threshold. Morphological features of the copper can be summarized as follows: (i) superficial damages, which take crater-shaped form at a higher number of accumulated laser pulses, (ii) development of melt pools with visible bubbles inside the damage region, (iii) formation of solid droplets at near periphery, and (iv) presence of halo effect at the irradiated surface. The laser induced surface changes were influenced by the target plasma formation. The formation of plasma influenced the laser-target interaction in two opposite ways: trough absorption of laser energy by the plasma, i. e. trough the effect of plasma shielding, and trough energy transfer from the plasma to the sample. Optical emission spectra were compared for laser induced plasma originated by a single and by cumulative laser pulses. It was found that plasma dimensions and emission intensities have a strong correlation with the number of accumulated laser pulses. Enhancement of both atomic and ionic copper lines was registered when laser induced plasma originated from a single pulse. Chemical analysis of the surface showed a tendency of copper content increase and oxygen content reduction when going from non-irradiated region to the central irradiated region. In the central damage zone, nearly pure copper was present which can be advantageous for some applications due to considerably lower contamination. (C) 2013 Elsevier B.V. All rights reserved.

AB  - Silicon-based nanoparticles were produced by irradiating a single-crystal silicon target with 10.6 mu m nanosecond transverse excited atmospheric (TEA) pulsed CO2 laser in de-ionized water. The effects of the laser pulse energies and repetition rate were studied. To reveal the role of thermal effects, a low laser repetition rate has been applied, excluding the interaction of the laser beam with the previously generated cavitation bubble. The analysis of the influence of the laser pulse energies and the laser repetition rate showed that the increase of the laser pulse energies leads to an increase of the nanoparticle size. An explanation of such results was proposed and the importance of the role of the target surface temperature in the ablation process is discussed.

AB  - The response of titanium surface irradiated with high intensity (10(13) - 10(15) W/cm(2)) Ti:sapphire laser was studied in vacuum. Most of the reported investigations were conducted with nano- to femtosecond lasers in gas atmospheres while the studies of titanium surface interacting with femtosecond laser in vacuum are scarce. The laser employed in our experiment was operating at 800 nm wavelength and pulse duration of 60 fs in single pulse regime. The observed surface changes and phenomena are (1) creation of craters, (2) formation of periodic surface structures at the reduced intensity, and (3) occurrence of plasma in front the target. Since microstructuring of titanium is very interesting in many areas (industry, medicine), it can be concluded from this study that the reported laser intensities can effectively be applied for micromachining of the titanium surface (increasing the roughness, formation of parallel periodic surface structures etc.).
