Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as mod ...
Medical-grade poly(vinyl chloride) (PVC) was chemically modified to study how the incorporation of monovalent silver influences Pseudomonas aeruginosa adhesion and colonization. The modification investigated consisted of a radio frequency-oxygen (RF-O-2) g ...
We demonstrate a monolithic polymer electrolyte membrane fuel cell by integrating a narrow (200 mu m) Nafion strip in a molded polydimethylsiloxane (PDMS) structure. We propose two designs, based on two 200 mu m-wide and two 80 mu m-wide parallel microflui ...
Hybrid solids, made of chem. dissimilar components, have drawn much interest in advanced materials synthesis due to their structural versatility and multifunctional properties. For example, metal-org. frameworks (MOFs) have been extensively explored for th ...
We report on a multi-technique investigation of the supramolecular organisation of N,N-diphenyl oxalic amide under differently dimensioned environments, namely three-dimensional (3D) in the bulk crystal, and in two dimensions on the Ag(111) surface as well ...
Conditions have been developed for the multicomponent synthesis of di- and tetrapeptide based on the unique reactivity of alpha -isocyanoacetic acids (including its alpha -substituted derivs.) by an Ugi four-component, five-center reaction. Simply mixing a ...
A two-step sequence involving an Ugi four-component reaction and an intramol. nucleophilic arom. substitution (SNAr) has been developed for the rapid access to biaryl-ether contg. macrocycles. For example, reacting heptanal with butylamine, (3-hydroxypheny ...
The catalytic influence of major metal species found with waste wood (Na, K, Ca, Mg, Zn, Pb, Cu) was studied during the gasification of nitrate salt impregnated charcoal with CO2 at 800degreesC in the kinetically controlled regime. In contrast with literat ...
Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...
As the World Health Organization (WHO) progresses with provisional Drinking Water Guidelines of 1 mu g/L for microcystin-LR and a proposed Guideline of 1 mu g/L for cylindrospermopsin, efficient treatment strategies are needed to prevent cyanotoxins such a ...
