Abstract The transition to alternative electrical and thermal energy sources has opened up many promising areas for the hydrogen-containing fuel study. When assessing environmental prospects of using a solid oxide cell, it was found that carbon dioxide is obtained as by-product, which must be captured disposed of. Carbon by physical absorption, chemisorption, adsorption, catalytic hydrogenation...

abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...

The GIAO-PBE0/SARC-ZORA(Pt)∪6-31+G(d)(E) (E = main group element) computational protocol without including relativistic and spin-orbit effects is offered here for the accurate prediction of the (195)Pt NMR chemical shifts of a series of cis-(amine)2PtX2 (X = Cl, Br, I) anticancer agents (in total 42 complexes) and cis-diacetylbis(amine)platinum(II) complexes (in total 12) in solutions employing...

Two vanillin-hydrazone compounds as the colorimetric amine detection during chicken meat spoilage are described. hydrazone (1 and 2) have been synthesized from condensation reaction of vanillin with phenylhydrazine 2,4-dinitrophenylhydrazine. Their properties for recognition were determined by naked eye UV-vis spectra. indicators investigated toward primary amine: butylamine (BA); secondary dim...

Synthesis and properties are described of multilayered stationary phases containing quaternary amine functional groups used for the analysis of inorganic anions by ion chromatography. The bonded phases were characterized by elemental analysis, solid state (13)C NMR spectroscopy and chromatographic methods. The surface of polyhydroxyethyl methacrylate (solid support) was coated with polymeric la...

The solvation of prilocaine has been investigated in pure water and in an amphiphilic methanol/water solution using a combination of neutron diffraction with isotopic substitution augmented by Empirical Potential Structure Refinement (EPSR) simulations. This combination of techniques allows for details of the solvation structure on the atomic scale to be unravelled. The hydration of prilocaine ...

Silicon nitride is the most commonly used passivation layer in biosensor applications where electronic components must be interfaced with ionic solutions. Unfortunately, the predominant method for functionalizing silicon nitride surfaces, silane chemistry, suffers from a lack of reproducibility. As an alternative, we have developed a silane-free pathway that allows for the direct functionalizat...

Low density composites of sodium montmorillonite and poly(amide-imide) polymers have been created using an ice templating method, which serves as an alternative to the often-difficult foaming of high temperature/high performance polymers. The starting polymer was received in the poly(amic acid) form which can be cured using heat, into a water insoluble amide-imide copolymer. The resulting mater...

The cation exchange chromatographic separation of pyridine, monoethanol amine (MEA) and triethanol amine (TEA) have been explored from source to receiving phase through a fiber supported solid membrane (FSSM). The FSSM were prepared by chemical modification of cellulose fibers with introducing the carboxylic acid ion exchanging groups. The experimental values explored were concentration of pyri...
