New facile one-pot synthesis of S-alkyl thiolcarbamates from xanthogenate in water
(Springer Wien, Wien, 2013)
A simple and efficient one-pot synthesis was developed for the preparation of S-alkyl thiolcarbamates from xanthogenate without catalyst using water as a solvent. The water can be recycled after removal of the product. The ...
Influence of chemical stress on sulfur-polymer composite structure
(New Developments in Polymer Composites Research, 2013)
Sulfur- polymer composites are high performance thermoplastic materials made of mineral aggregate, filler, and modified sulfur binder, instead of cement and water as in ordinary Portland cement- based composites at ...
Supercritical extraction of phloroglucinols from St. John's wort (Hypericum Perforatum L.) - Process optimization, mathematical modeling and antimicrobial activity
(Phytochemicals: Occurrence in Nature, Health Effects and Antioxidant Properties, 2013)
St. John's Wort (Hypericum perforatum L.) has been widely used as an anti-inflammatory and healing agent in traditional medicine. Some para-pharmaceutical products, prepared from the extract of St. John's Wort, are frequently ...
Improvement of the mechanical properties of spark plasma sintered hap bioceramics by decreasing the grain size and by adding multi-walled carbon nanotubes
(International Institute for the Science of Sintering, Beograd, 2013)
Composites based on HAP and oxidized multi-walled carbon nanotubes (o-MWCNT) and monophase HAP materials were processed by spark plasma sintering. Starting from stoichiometric nano-sized HAP powder, monophase bioceramics ...
A study of transglucosylation kinetic in an enzymatic synthesis of benzyl alcohol glucoside by alpha-glucosidase from S-cerevisiae
(Maik Nauka/Interperiodica/Springer, New York, 2013)
alpha-1,4-Glucosidase from Saccharomyces cerevisiae is an enzyme which is widely used in synthesis of different drugs. Glucosidase inhibitors are studied as potential drugs for prevention of HIV and diabetes. For understanding ...
Extensive feedwater quality control and monitoring concept for preventing chemistry-related failures of boiler tubes in a subcritical thermal power plant
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Prevention and minimizing corrosion processes on steam generating equipment is highly important in the thermal power industry. The maintenance of feedwater quality at a level corresponding to the standards of technological ...
Solvatochromic and quantum chemical investigations of newly synthesized succinimides: substituent effect on intramolecular charge transfer
(Springer Wien, Wien, 2013)
Two series of 1-aryl-3-phenyl- and 1-aryl-3,3-diphenylpyrrolidine-2,5-diones were synthesized and their solvatochromic properties were studied in a set of 15 solvents of different polarity. The effect of specific and ...
Electrodeposition of Zn-Mn alloys at high current densities from chloride electrolyte
(Springer, New York, 2013)
The Zn-Mn alloy electrodeposition on a steel electrode in chloride electrolyte was investigated with the aim of obtaining deposits with as high as possible Mn percent. It was found that the deposition current density and ...
Influence of starch sodium octenyl succinate on rheological behaviour of wheat flour dough systems
(Elsevier Sci Ltd, Oxford, 2013)
Experimental and theoretical influence of addition of various amounts of three types starch sodium octenyl succinate (OSA) granules (0-20%): (a) non-physically modified, (b) pregelatinized and
Particle velocities in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier, Amsterdam, 2013)
Particle velocities have been measured in two-dimensional water fluidized beds of mono-sized spherical glass particles d(p) = 1.94, 2.98, 4.00 and 6.00 mm in diameter. For each particle size, a separate column was constructed ...
