The chemical composition of kelps (e.g. polyphenolics) deters grazing by herbivores, but kelp detritus is potentially a source of nutrition for suspension feeders. The effects of kelp detritus derived from two species [Agarum fimbriatum Harvey and Costaria costata (Turner) Saunders] on feeding of oysters, Crassostrea gigas Thunberg, and mussels, Mytilus trossulus Gould, were examined in feeding...

A predictive model correlating the properties of a catalyst with its performance would be beneficial for development, from biomass waste, new, carbon-supported and Earth-abundant metal oxide catalysts. In this work, effects copper iron crystallite size on catalysts in reducing nitrogen oxides, terms conversion selectivity, are investigated. The prepared via incipient wetness method over activat...

Abstract Selective oxidation of saturated C( sp 3 )–H bonds in hydrocarbon to target chemicals under mild conditions remains a significant but challenging task because the chemical inertness and high dissociation energy bonds. Semiconductor photocatalysis can induce generation holes oxidative radicals, offering an alternative way toward selective hydrocarbons ambient conditions. Herein, we cons...

abstract background: molecular imprinting is a method for synthesizing polymers with structure-selective adsorption properties with applications such as, selectivity binding, drug delivery systems and anti-bodies. the present study aims at optimizing the preparation of molecularly imprinted polymer (mip) against l-phenylalanine, in order to increase phenylalanine-binding in enzymatic intestinal...

Deuterated organic molecules provide the basis for many applications in life sciences and material research. Thus, methodologies to access labeled compounds with defined selectivity continue be important. Using KOtBu as base DMSO-d6 deuterium source, we present a general applicable method selective deuteration of set nitrogen-containing heterocycles (pyridines, azines bioactive molecules). Expe...

A nickel-catalyzed cross-coupling amination with weak nitrogen nucleophiles is described. Aryl halides as well aryl tosylates can be efficiently coupled a series of N-nucleophiles, including anilines, sulfonamides, sulfoximines, carbamates, and imines via concerted paired electrolysis. Notably, electron-deficient anilines sulfonamides are also suitable substrates. Interestingly, when benzopheno...

We report the effect of N2 addition to C4F8 and C4F8 /Ar discharges on plasma etching rates of organosilicate glass ~OSG! and etch stop layer materials (Si3N4 and SiC!, and the results of surface chemistry studies performed in parallel. N2 addition exhibits different effects in C4F8 and C4F8 /Ar plasmas, which may be explained by a higher plasma density, electron temperature, and possibly, the ...

Vinyl chloride, the monomer of polyvinyl is produced primarily via acetylene hydrochlorination catalyzed by environmentally toxic carbon-supported HgCl2. Recently, nitrogen-doped carbon materials have been explored as metal-free catalysts to substitute Herein, we describe development a cationic covalent triazine network (cCTN, cCTN-700) that selectively catalyzes hydrochlorination. cCTN-700 exh...

Methane pyrolysis can produce many valuable products besides hydrogen, e.g., C2 compounds or carbon black. In the conditions provided by microwave plasma, distribution of these might be shifted addition hydrogen and nitrogen. this work, different ratios H2:CH4, ranging from 0:1 to 4:1, were tested. The most unambiguous promising result was obtained for highest H2:CH4 ratio. For ratio, a signifi...
