Effect of synthesis parameters on polymethacrylic acid xerogel structures and equilibrium swelling
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Hydrogels based on crosslinked polymethacrylic acid were synthesized via free-radical polymerization in aqueous solution, using N,N'-methylene bisacrylamide as a crosslinking agent and 2,2'-azobis-[2-(2-imidazolin-2-yl)propane] ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
Landfill closure best available technique development: case study of Serbia
(Journal of Environmental Protection and Ecology, 2020)
Waste disposal is the last but inevitable step in waste management and it significantly effects the environment. According to the Serbian Waste Management Strategy, disposal sites should be closed and new, sanitary regional ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
Did the Iceman Know Better? Screening of the Medicinal Properties of the Birch Polypore Medicinal Mushroom, Piptoporus betulinus (Higher Basidiomycetes)
(Begell House Inc, Danbury, 2015)
The birch polypore Piptoporus betulinus was among two mushrooms that were found in the Iceman's bag. Recent studies indicated that P. betulinus was probably used as a religious and medicinal item. In order to examine the ...
Antimicrobial Activity of Thiocarbohydrazones: Experimental Studies and Alignment-Independent 3D QSAR Models
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Due to the rise of microbial strains resistant to conventional therapies, there is an urgent need for finding the new antimicrobial chemotypes. Heterocyclic compounds such as thiocarbohydrazones (TCHs) are able to interact ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer, New York, 2019)
Secondary alkaline lead slag (SALS), generated during lead-acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Surface-modified TiO2 powders with phenol derivatives: A comparative DFT and experimental study
(Elsevier, Amsterdam, 2017)
The charge transfer complex formation between TiO2 powder and variety of phenol derivatives (phenol, 4-nitrophenol, 4-bromophenol, 4-tert-butylphenol, hydroquinone) was achieved. The red-shift of optical absorption was ...
