AB  - By means of a density functional theory (DFT) based augmented plane waves plus local orbitals (APW ​+ ​lo) method, we study the electric field gradients (EFG) in Ta and Cd-doped Zr–Al intermetallics. Comparing the obtained results with the experimental data obtained from the perturbed angular correlation (PAC) measurements, we conclude that Ta atoms always replace Zr in all the investigated compounds. Our results confirmed the previous experimental assumption that Cd substitutes exclusively for Al in ZrAl3 and Zr2Al3. In the case of Zr2Al our calculations suggest that Cd can probably substitute on both Zr and Al lattice sites, while in Zr3Al, it is most likely to occupy Al position. The effects of the distance between the impurity atoms in the supercells and the deviation of the c/a ratio are also discussed.

AB  - Eu3+-doped YxLu1−xNbO4 (x = 0, 0.25, 0.5, 0.75, 1) were prepared by the solid-state reaction method. YNbO4:Eu3+ and LuNbO4:Eu3+ crystallize as beta-Fergusonite (SG no. 15) in 1–10 μm diameter particles. Photoluminescence emission spectra show a slight linear variation of emission energies and intensities with the solid-solution composition in terms of Y/Lu content. The energy difference between Stark sublevels of 5D0→7F1 emission increases, while the asymmetry ratio decreases with the composition. From the dispersion relations of pure YNbO4 and LuNbO4, the refractive index values for each concentration and emission wavelength are estimated. The Ω2 Judd–Ofelt parameter shows a linear increase from 6.75 to 7.48 × 10−20 cm2 from x = 0 to 1, respectively, and Ω4 from 2.69 to 2.95 × 10−20 cm2. The lowest non-radiative deexcitation rate was observed with x = 1, and thus LuNbO4:Eu3+ is more efficient phosphor than YNbO4:Eu3+.

AB  - Graphene doped by alkali atoms (ACx) supports two heavily populated bands (π and σ) crossing the Fermi level, which enables the formation of two intense two-dimensional plasmons: the Dirac plasmon (DP) and the acoustic plasmon (AP). Although the mechanism of the formation of these plasmons in electrostatically biased graphene or at noble metal surfaces is well known, the mechanism of their formation in alkali-doped graphenes is still not completely understood. We shall demonstrate that two isoelectronic systems, KC8 and CsC8, support substantially different plasmonic spectra: the KC8 supports a sharp DP and a well-defined AP, while the CsC8 supports a broad DP and does not support an AP at all. We shall demonstrate that the AP in an ACx is not, as previously believed, just a consequence of the interplay of the π and σ intraband transitions, but a very subtle interplay between these transitions and the background screening, caused by the out-of-plane interband C(π)→A(σ) transitions.

AB  - A series of LaGa1–xO3:Cr3+x phosphors (x = 0.002, 0.005, 0.01, 0.02, 0.04) were synthesised by solid-state reaction and structurally characterised by Rietveld refinement from powder X-ray diffraction data. Amongst the five compounds, that with x = 0.01 exhibited the highest photoluminescence quantum yield at room temperature, those with higher doping levels probably suffering from self-quenching of the luminescence. This compound was selected for study of the temperature-dependence of the optical properties. The emission spectra recorded over the range 300–600 K reveal distinct features: a broad band that initially increases with temperature, attributed to fluorescence from the 4T2 excited state, and a series of sharp peaks that monotonically decline with temperature, attributed to phosphorescence from the 2E. The thermometry capabilities of LaGa0.99O3:Cr0.01 were probed by the luminescence intensity ratio (LIR) method using the broad 4T2 band relative to the sharp 2E peaks. To overcome the difficulties associated with the significant overlap of the broad and sharp emissions of Cr3+, a novel method was applied in which the deconvolution of broad peaks was performed in two steps, by fitting the broad bands to the curve sections without the sharp peaks. The ratio of the deconvoluted 4T2 and 2E intensities gave an excellent fit to the Boltzmann distribution, with an energy gap between them of 2172 cm–1. The high relative sensitivity at room temperature of ca. 2.5% K–1 demonstrates very good potential of LaGa0.99O3:Cr0.01 for thermometry in the first biological window of transparency, relevant for in vivo biomedical applications.

AB  - Green roof systems have become an important part in creating sustainable cities. They can provide a wide range of economic, environmental, and social benefits. The goal of this research was to quantify the thermal performance improvements from a green roof with mineral wool substrate installed on a school building in a humid subtropical climate. In-situ measurements during a summer period included heat fluxes through the green and reference roof, vertical temperature profile through both roofs, the local air temperature above roofs, and local meteorological parameters. Furthermore, the summer thermal performance of green and reference roof and the green roof cooling effect were evaluated concerning meteorological parameters using the Pearson correlation analysis. The results indicate that the green roof layers have improved thermal performance of the roof with respect to reduced conductive heat flow by 57% and delayed heat transfer. The maximum and averaged reference roof to green roof outdoor surface temperature difference was 27.5 °C and 5.5 °C, respectively. It was found that ambient temperature and relative humidity have a dominant role on the thermal performance of the green and reference roof, while solar radiation and ambient temperature present the key meteorological determinants of the green roof cooling effect.

AB  - This paper describes Mn5+-activated Sr3(PO4)2and Ba3(PO4)2phosphors as near-infrared lifetime-based luminescence thermometry probes. Materials were prepared by a solid-state method, and their rhombohedral structures were confirmed by X-ray diffraction analysis. Diffuse reflectance measurements showed broad and strong absorption between 650 and 950 nm covering the first biological transparency window and having an absorption maximum at ∼660 nm. By switching Sr with Ba, the following changes in the photoluminescent properties were observed: (i) a red shift of the emission maximum (1173 nm → 1191 nm) and (ii) a decrease in the excited-state lifetime. Thermometric properties of the phosphors were assessed by measuring and analyzing the temperature dependence of the Mn5+excited-state lifetime. Lifetime-based luminescence thermometry revealed a relative sensitivity of 0.5% K-1at 310 K (physiologically relevant range) and a maximal value of ∼1% K-1at temperatures between 400 and 500 K. © 2022 American Chemical Society.

AB  - The ultra-supercritical double-reheat boiler has attracted more attention because of high parameters (steam with high temperature and pressure), low pollution and large capacity. However, there are some difficulties in the development of this technology, such as adjusting the reheat steam temperature. In this study, computational fluid dynamics simulation is used to analyze a 660 MW double-reheat tower-type pulverized coal-fired boiler. The influence of flue gas recirculation (FGR) on heat transfer characteristics and combustion process in the furnace (including heating surfaces in the upper parts of the furnace) are evaluated. The user-defined function approach predicates the CO reduction effect on NOx. The results show that the flow at the horizontal section through the centerline of recirculating flus gas nozzles is rotating. The velocity distribution changes into an elliptical rotating flow when FGR ratio is 20%. At higher FGR ratios, the high-temperature area (1565–1700 K) shrinks and both the NOx concentration at the low-temperature superheater outlet and the O2 concentration in the burner zone descend. The O2 concentration at the low-temperature superheater outlet first increases and then decreases. In the main combustion zone, the heat flux peak of water-cooled wall is about 330 kW m−2. As FGR ratio increases from 0% to 20%, the rate of heat absorption of water-cooled wall to that of total boiler decreases by 3.50%. These rates for reheater and superheater increase by 2.53% and 2.13%, respectively.

AB  - This book chapter provides a comprehensive overview of research on the energy landscapes of zinc oxide (ZnO), one of the most investigated materials, due to its great variety of technological and industrial applications. Thus, not only crystalline and bulk ZnO – both pure and doped – but also ZnO surfaces, monolayers, nanotubes, clusters, cluster-assembled materials, and ZnO nanostructures and nanomaterials in general are of great interest. In order to fully explore the energy landscape of ZnO on all length scales ranging from bulk, layers, and nanotubes to clusters, a broad range of landscape exploration methods has been employed in the literature, including, e.g., global optimisation for structure prediction using empirical potentials, local optimisation at the ab initio level, and the prescribed path algorithm, the threshold algorithm, and metashooting for the study of the barrier structures and transition regions of the landscapes of ZnO. As examples of such landscape investigations, doped and pure crystalline ZnO, as well as ZnO surfaces, clusters, and nanotubes will be discussed.

AB  - In this study, we have investigated the effect of thickness on the structural and optical properties of copper (Cu) helical nanostructures. Thin films with thicknesses of 160 nm, 280 nm, 450 nm, and 780 nm were obtained by e-beam glancing angle deposition. The morphology and the microstructure were studied by field emission scanning electron microscopy, x-ray diffraction and transmission electron microscopy, while for the optical analysis measurements spectroscopic ellipsometry was used. The results show that the deposited structures are porous with nanometer-sized crystallites preferentially oriented along (111) planes, as well as that the diameter of the helices increases with thickness. Detailed analyses of optical properties have demonstrated that the dielectric function of Cu structures is greatly influenced by the films thicknesses. With increasing thickness from 160 nm to 780 nm, the surface plasmon resonance peak was shifted from 1.31 eV to 1.05 eV, which was correlated with the growth mechanism and the size of deposited nanostructures.

AB  - Alzheimer’s disease (AD), a devastating neurodegenerative disease, is the focus of pharmacological research. One of the targets that attract the most attention for the potential therapy of AD is the serotonin 5HT6 receptor, which is the receptor situated exclusively in CNS on glutamatergic and GABAergic neurons. The neurochemical impact of this receptor supports the hypothesis about its role in cognitive, learning, and memory systems, which are of critical importance for AD. Natural products are a promising source of novel bioactive compounds with potential therapeutic potential as a 5HT6 receptor antagonist in the treatment of AD dementia. The ZINC—natural product database was in silico screened in order to find the candidate antagonists of 5-HT6 receptor against AD. A virtual screening protocol that includes both short-and long-range interactions between interacting molecules was employed. First, the EIIP/AQVN filter was applied for in silico screening of the ZINC database followed by 3D QSAR and molecular docking. Ten best candidate compounds were selected from the ZINC Natural Product database as potential 5HT6 Receptor antagonists and were proposed for further evaluation. The best candidate was evaluated by molecular dynamics simulations and free energy calculations.

AB  - Recently, the idea of injecting energy with electromagnetic radiation in order to heat the plasma to achieve controlled fusion has been abandoned. This initially favored mechanism was rejected because it has been shown that after a certain temperature the plasma glows and acts as a mirror that reflects electromagnetic radiation. For that reason, today the energy is injected into the plasma by electrons. For this purpose, pulses from several electron beam generators, based on a Marx generator, are synchronously fired into the plasma. In addition to economic problems, the biggest problem of this method is the appearance of jitter, i.e., pulses with a width of about 5 ns are not simply added up but propagated in time due to the impossibility of synchronizing simultaneous triggering of the multiple electronic generators. In order to avoid this, the possibility of monitoring the pulses from an individual electron beam generator for the purpose of online synchronization is investigated in this paper. The voltage pulse monitoring of the electron beam generator was measured by instruments with the fastest response—the electro-optical Kerr effect and a fast capacitive probe. The obtained results showed that the electro-optical Kerr response is somewhat faster but much more complicated, so the use of fast capacitive probes is recommended for practice.

The performed CFD simulations showed good agreement with experimental temperature measurements. Numerical results allowed in-depth analysis of flow field and temperature distribution inside the storage. It was discovered that the flow field is highly non-uniform, which consequently leads to an uneven temperature distribution of pallets with products. However, a high inlet mass-flow rate ensured that all pallets reach the designed temperature.

AB  - The content of combustible elements in solid mineral fuels (carbon, hydrogen, etc.) are very important, since they most directly affect the heat value. It should be noted that the fuel heat value depends on many other constituents, such as ash and moisture. In this paper, special attention has been paid to carbon content. In solid mineral fuels, carbon is found alone or bound in the form of various compounds. One of them is mineral carbonate compounds bound as carbonate carbon, which originates from absorbed CO2 from atmosphere. Determination of carbonate carbon content of solid mineral fuels was performed by standard gravimetric method (according to ISO 925: 2019), and newly developed instrumental method, using thermogravimetric analyzer LECO TGA 701. Comparison of obtained experimental results was done. Four types of coal, Kolubara lignite, Kostolac lignite, brown coal, and control coal sample were included in experimental analysis. In addition, moisture in the samples was also determined using analytical method and inspected using LECO TGA 701 thermogravimetric analyzer, as well as total carbon content using the LECO CHN 628 elemental analyzer. An analysis and comparison of the obtained results was performed, and comments and conclusions are presented. The experiments were done in the department for fuel characterization, Laboratory for Thermal Engineering and Energy, Institute of Nuclear Sciences Vinca.

AB  - Fluorescent nanocomposite films were prepared by solution mixing of polyvinyl alcohol (PVA) and tryptophan functionalized silver (AgTrp) nanoparticles. Synchrotron excitation deep-ultraviolet (DUV) fluorescence imaging was used to follow the distribution of AgTrp nanoparticles within the polymer matrix. Pronounced growth of dendrite-like structures in the presence of AgTrp nanoparticles was confirmed by bright field and fluorescence imaging as well as with atomic force microscopies. Both tryptophan and AgTrp nanoparticles influence thermal properties of the matrix. Differential scanning calorimetry measurements showed that they reduce crystallinity and significantly increase the glass transition temperature of PVA (in the case of PVA-AgTrp film the Tg increases by ~20 °C). Dielectric properties of the films were studied under two different conditions (dark and illumination). The illumination with 250 nm light induces a significant increase in conductance of the PVA-AgTrp nanocomposite. The relative changes, with respect to the conductance measured in the dark, were almost ~200%.

AB  - Judd–Ofelt theory is a cornerstone of lanthanides’ spectroscopy given that it describes 4fn emissions and absorptions of lanthanide ions using only three intensity parameters. A self-referenced technique for computing Judd–Ofelt intensity parameters from the excitation spectra of Eu3+-activated luminescent materials is presented in this study along with an explanation of the parametrisation procedure and free user-friendly web application. It uses the integrated intensities of the 7F0 → 5D2, 7F0 → 5D4, and 7F0 → 5L6 transitions in the excitation spectrum for estimation and the integrated intensity of the 7F0 → 5D1 magnetic dipole transition for calibration. This approach facilitates an effortless derivation of the Ω6 intensity parameter, which is challenging to compute precisely by Krupke’s parametrisation of the emission spectrum and, therefore, often omitted in published research papers. Compared to the parametrisation of absorption spectra, the described method is more accurate, can be applied to any material form, and requires a single excitation spectrum.

AB  - A porous hematite/alumina nanocomposite is produced by sol-gel combustion synthesis. The XRPD, Raman and FTIR methods show the presence of α-Fe2O3 phase while SEM, TEM, EDS and BET techniques further reveal the formation of porous ellipsoid-like nanostructure of hematite nanoparticles coated by amorphous alumina. Hematite nanoparticles have a size of ~40 nm whereas the porous hematite/alumina nanocomposite particles are ~100 nm in size with characteristic pores of ~7 nm. The M(H) at 300 K exhibits coercivity HC = 293 Oe and magnetization MS = 2.71 emu/g and at 5 K HC = 1150 Oe and MS = 9.25 emu/g. The M(T) under H = 100 Oe shows a bifurcation between ZFC/FC magnetization curves at all measurement temperatures Tirr>350 K (irreversibility temperature) and blocking temperature at TB ~ 305 K. Unexpectedly, the M(T) measurements under H = 10 kOe reveal the suppressed Morin transition at TM = 225 K. The analysis of the results and data from the literature reveal that the porous surface structure of hematite induces the atypical magnetic properties. A magnetic resonance imaging (MRI) properties show the transverse relaxivity rate (r2) of 0.44 mM−1s−1 at 7 T and 1.06 mM−1s−1 at 15.2 T. The investigated nanocomposite particles could be useful in biomedical applications due to their low cytotoxicity and porous nanostructure.

AB  - Passive solid state dosimeters, such as thermoluminescence dosimeters, provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective of this paper is to provide a comprehensive review on the use of thermoluminescent dosimetry methods for monitoring radiation dose in the environment. The article presents the part of the research results of the project PREPAREDNESS (EMPIR 2016 call for Metrology for Environment joint research project) with a particular objective to harmonize procedures used by dosimetry services, relevant authorities and Institutes across the Europe. To achieve this, different monitoring routines that are based on passive environ mental dosimetry methods are investigated. Differences in performing specific steps such as preheating, reading, annealing, minimizing fading, and others, are analyzed. The investigation was performed by means of qualitative literature review that showed the lack of information about specific steps. The conclusion of this work is that thermoluminescent dosimetry measurement system has to be type-tested even though the testing procedure is complicated. In addition to this, control dosimeters should be introduced, International Organization for Standardization protocols should be followed during calibration, and finally, parameters influencing the measurement uncertainty have to be identified and well understood in order to pro duce ac cu rate dose measurement results.

AB  - This paper provides insights into understanding the physical and chemical changes that take place during re-heating process of Poplar fluff bio-char derived by carbonization at high operating temperature (850 °C). Bio-char re-heating experiments were performed by simultaneous TGA-DTG-DSC techniques in N2 atmosphere at 5, 10, 15 and 20 °C min−1. Kinetic modeling of the process was done through implementation of model-free and model-based approaches. It was identified that re-heating process contains two stages. The first was described by single consecutive reaction step (up to 200 °C) which is attributed to removal of physisorbed moisture at surface and in pores of carbonized material, while second was described by multiple reactions, including one consecutive step and two competitive steps. In the last, consecutive pathway includes reduction of PAH compounds (400–600 °C) into smaller ones, changing degree of condensation of carbon structure continuously. Competitive steps encompass competition between C10H8 (naphthalene) (700–780 °C) and C9H8 (indene) (700–750 °C) molecules decomposition. It was found that used heating rates have great influence on regulating the amount of gaseous (combustible) products from these reactions. It was established that internal heat and mass transfer processes control the release of products. Changing the pyrolysis mechanism with temperature of carbonized bio-char is the main factor for occurrence of true kinetic compensation effect, which is also discussed by applied isothermal life-time analysis. © 2021 Elsevier Ltd

AB  - This paper provides in-depth knowledge about the evolved gas analysis interpretation via newly proposed semi-quantitative approach, arising from thermogravimetric analysis (TGA) – mass spectrometry (MS) coupled measurements, for studying pyrolysis behavior of three kinds of biomass waste materials (spent coffee grounds, beech sawdust and wheat straw). TGA – MS coupling allows accurate correlation between molecular ion peak and fragment peaks to the corresponding mass loss rates from derivative thermogravimetry curves. Within proposed semi-quantitative analysis, MS spectra were interpreted through the comparative analysis of compounds fragments and of the compound itself, where the single atomic mass unit was identified by multiple compounds exhibition. It was shown that by this procedure which involves overlapping multiple curves supervising, the identification of gases in volatiles complex scheme becomes more simplified. By setting up semi-quantitative formulas, easy and reliable calculations of gaseous products yield and syngas energy capacities are possible to achieve. The H2/CO ratio derived from the proposed method for wood waste product (sawdust) is in an excellent agreement with H2/CO ratio for sawdust syngas production, in fuel reactor for biomass gasification and H2 production. © 2021 Elsevier B.V.

AB  - Thermally accelerated oxidative degradation of wolfberry pulp was kinetically monitored using model-free and model-based approaches. Kinetic calculations were performed based on simultaneous thermal analysis measurements in an air at four different heating rates. From kinetic analysis, new developed mechanistic scheme which is responsible for wolfberries anti-oxidative behavior was proposed. It was found that thermo-oxidative process proceeds through multiplestep mechanism including sum of two independent reaction sets, via consecutive and competitive steps. It was established that rutoside degradation pathway to flavonol through hydrolysis reaction is rate-determining step of considered process. Furthermore, it was found that key flavonol compound degraded by competitive reactions mechanism forming such kinetic branches, which lead to compounds responsible for wolfberries antioxidant activity. It was established that flavonol oxidative cleavage reaction and oxidative polymerization are main chemical routes which are very important in a complex antioxidant mechanism for scavenging free radicals in wolfberries oxidative stress response.

AB  - Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 °C for the process of geopolymerization. Mixtures of Na2SiO3and NaOH of different molar concentrations (from 2M to 8M with step 2) were used as an alkaline activator. The sample with the highest NaOH concentrationalso shows the highest values of all thermodynamic parameters.Metakaolin, obtained by calcination of kaolin at 750 °C, was used as the starting material.The samples were characterized by X-ray diffraction (XRD),FTIR and Raman spectroscopy, Scanning Electron Microscopy (SEM), and Energy-Dispersive X-Ray (EDX) Spectroscopy. Results of FTIR analysis correlated with results of Raman Spectroscopy. Due to the polymerization process, the changes in the phonon spectrum were confirmed. The different concentra-tions of activators do not notably change the Si/Al ratio.

AB  - In this work we deposited nickel thin films by Glancing Angle Deposition at two different angles (65 degrees and 85 degrees) onto glass substrates. The structure of the films, thicknesses between 50 and 200 nm, was studied by scanning electron microscopy, atomic force microscopy and X-ray diffraction, while the chemical properties were analyzed using X-ray photoelectron spectroscopy. According to the obtained results it can be seen that the deposition angle has influence on porosity, crystallinity and surface roughness. Optical properties were investigated by spectroscopic ellipsometry and electrical properties were measured by four point probe. Spectroscopic ellipsometry revealed that the refractive index and extinction coefficient varied with thickness and deposition angle, which can be correlated with changes in microstructure and porosity of Ni films. The observed variations in resistivity could be attributed to the changes in the width of the columns, as well as to the amount of oxide present in the samples.

AB  - Background: Gentiana lutea (GL), commonly known as yellow gentian, bitter root, and bit-terwort, belongs to family Gentianaceae. GL belongs to genus Gentiana, which is a rich natural source of iridoids, secoiridoids, xantones, flavonoids, triterpenoids, and carbohydrates. Medicinal plants from Gentiana species have anti-oxidant, anti-inflammatory, anti-mitogenic, anti-proliferative, and lipid-lowering effects, as well as a cardioprotective, hypotensive, vasodilator and anti-platelet activities. Objective: We reviewed the recent literature related to the effects of Gentiana species, and their active components on vascular diseases. Methods: Data used for this review were obtained by searching the electronic database [PUB-MED/MEDLINE 1973-February 2020]. The primary data search terms of interest were: Gentiana lutea, Gentienacea family, phytochemistry, vascular diseases, treatment of vascular diseases, anti-oxidant, anti-inflammatory, anti-atherogenic. Conclusion: Gentiana species and their constituents affect many different factors related to vascular disease development and progression. Therefore, Gentiana-based therapeutics represent potentially use-ful drugs for the management of vascular diseases. © 2021 Bentham Science Publishers.
