TL;DR: In this article, an innocuous weak acid (citric acid) was applied to prepare cellulose nanocrystals (CNCs) and cellulose nibrils (CNFs) from bleached bagasse pulp accompanied by simultaneous modifications of the functional groups on their molecular interface.
114 citations
TL;DR: In this article, the surface of carbon fibers is functionalized by a reaction of naturally existing surface hydroxyl groups with isopropylidene malonate to graft terminal malonic esters, effectively creating a carboxyl functionalized surface.

TL;DR: In this article, the possibilities of low-temperature activation of CH4 and hydrogenation of CO2 were analyzed, and the feasibility of the direct conversion of CH 4 and CO 2 to oxygenated compounds by means of a two-step reaction sequence at low temperature was studied.

TL;DR: The complexing properties of calix[4]arenes in which carboxylic acid ligating groups have been progressively attached to the lower rim through the phenolic hydrogen atoms have been measured with alkali and alkaline-earth metal cations in methano by means of potentiometric titrations as discussed by the authors.
Abstract: The complexing properties of some calix[4]arenes in which carboxylic acid ligating groups have been progressively attached to the lower rim through the phenolic hydrogen atoms have been measured with alkali and alkaline-earth metal cations in methano by means of potentiometric titrations. The acid-base characteristics of these compounds were first determined. the weak acidities generally observed may be explained by the formation of intramolecular hydrogen bonding.

TL;DR: In this paper, the selectivity of polyvinyl chloride, styrene-divinylbenzene copolymers and carboxylic acid cation-exchange membranes was analyzed in terms of phenomenological coefficients using nonequilibrium thermodynamic principles.
