Improvement of the epoxy coating properties by incorporation of polyaniline surface treated TiO2 nanoparticles previously modified with vitamin B6
(Elsevier Science Sa, Lausanne, 2016)
Novel TiO2-PANI core-shell nanocomposite, prepared by in situ oxidative polymerization of aniline in the presence of TiO2 nanoparticles surface modified with vitamin B6, was used to reinforce epoxy resin. The size of ...
Periodic Operation with Modulation of Inlet Concentration and Flow Rate Part II: Adiabatic Continuous Stirred-Tank Reactor
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
The nonlinear frequency response (NFR) method, which is an analytical, fast, and easy method for evaluating the performance of forced periodically operated chemical reactors, was used to investigate possible improvements ...
Ultra-high pressure densification and properties of nanostructured SiC
(Elsevier Science Bv, Amsterdam, 2016)
Cubic SiC nano-powder particles were synthesized by a sal-gel process with an average grains size of 9.5 nm which were subsequently densified by using a high-pressure "anvil-type with hollows" apparatus at a pressure of 4 ...
Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
The re-use potential of espresso spent coffee grounds: Optimization of microwave-assisted extraction of polyphenols by use of response surface methodology and their effects on platelet function - pilot study
(Coffee: Production, Consumption and Health Benefits, 2016)
A huge amount of espresso spent coffee grounds (SCG) are obtained as a waste product during the preparation of coffee beverages (cialdes, K-cups and in metallic filters). Although considered a waste and an ecological threat, ...
A method for reactor synthesis based on process intensification principles and optimization of superstructure consisting of phenomenological modules
(Inst Chemical Engineers, Rugby, 2016)
A novel method for reaction synthesis is proposed. The method establishes strong interconnection between process intensification (PI) principles and process system engineering (PSE) techniques, which are used for problem ...
Kinetics and reactor modeling for CaO sorption-enhanced high-temperature water-gas shift (SE-WGS) reaction for hydrogen production
(Elsevier Sci Ltd, Oxford, 2016)
Hydrogen, an important energy carrier of the future, produces no pollution and has a high content of energy. It is formed as a direct product of the water-gas shift (WGS) reaction, which occurs in various processes for the ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier Science Bv, Amsterdam, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
A simple model of current-voltage characteristic for surrounding gate short-channel nanowire MOSFET
(Natl Inst Optoelectronics, Bucharest-Magurele, 2016)
A simple model of surrounding gate short-channel nanowire MOSFET current-voltage characteristic has been proposed. This model belongs to the class of drift-diffusion ones; it has been inspired by the corresponding long-channel ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
