Silicon Thin-Film Solar Cells Approaching the Geometric Light-Trapping Limit: Surface Texture Inspired by Self-Assembly Processes
(American Chemical Society (ACS), 2018)
A new device design of microcrystalline silicon thin-film solar cell allows for approaching the geometric light-trapping limit. The solar cell is based on triangular textured surfaces in combination with optimized front ...
Comparative Study of the Mineral Composition and Its Connection with Some Properties Important for the Sludge Flocculation Process-Examples from Omarska Mine
(MDPI, 2018)
Studied sludge samples are composed of major goethite and quartz; less clay minerals;
and minor magnetite, hematite, clinochlore and todorokite. They have quite similar qualitative,
but different semi-quantitative ...
Comparison of the crystallographic-chemical characteristics of sphalerites from the Kiževak ore deposit with some other deposits, part II: Construction of the four-component a0-FeS-P-T diagram (option I) and determination of the formation conditions / Поређење кристалографско-хемијских карактеристика сфалерита из рудног лежишта кижевак са неким другим рудним лежиштима, део ii: онструисање четворо-компонентног a0-fes-p-t дијаграма (опција I) и одређивање услова постанка
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of Serbia, 2018)
Same as in the I part of these investigations (Tančić, 2018), crystallographic-chemical characteristics for sphalerites from the ore deposit Kiževak were used for the comparison with the corresponding characteristics of ...
Thermodynamics of hydrolysis of cellulose to glucose from 0 to 100 °C: Cellulosic biofuel applications and climate change implications
(Elsevier, 2018)
Hydrolysis of cellulose to glucose is a key reaction in renewable energy from biomass and in mineralization of soil organic matter to CO2. Conditional thermodynamic parameters, ΔhydG’, ΔhydH’, and ΔhydS’, and equilibrium ...
Synthesis of calcium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2018)
A study is presented of phase transitions of acid CaHPW12O40∙6H2O salt of 12-tungstophosphoric acid and characterized in the temperature range from room temperature to 1093 K. The structure and its phase transformations ...
Laws of evolution parallel the laws of thermodynamics
(Elsevier, 2018)
We hypothesize that concepts from thermodynamics and statistical mechanics can be used to define summary statistics, similar to thermodynamic entropy, to summarize the convergence of processes driven by random inputs subject ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Application of the Entropy Concept to Thermodynamics and Life Sciences
(Brigham Young University, 2018)
Entropy, first introduced in thermodynamics, is used in a wide range of fields. Chapter 1 discusses some important theoretical and practical aspects of entropy: what is entropy, is it subjective or objective, and how to ...
The dispersion-flocculation behaviour of the natural raw clay samples from Omarska mine
(Akademija nauka i umjetnosti Republike Srpske, 2018)
In present paper there were studied the dispersion-flocculation behaviour of the primary natural raw clay samples from Omarska mine (Republic of Srpska, Bosnia and Herzegovina). During the processing of iron ore in the ...
Sinteza bakrom dopirane fosfat volframove bronze iz soli 12-volframfosforne kiseline
