Poly(methyl methacrylate)s containing pendant octamethylcalix[4]pyrrole subunits were prepared and demonstrated to be capable of extracting tetrabutylammonium chloride and fluoride salts from aqueous media.

Résultats : La littérature publiée a été récupérée par l’intermédiaire de recherches menées dans PubMed et The Cochrane Library le 8 juillet 2013 au moyen d’un vocabulaire contrôlé (« parvovirus » et « pregnancy ») et de mots clés (« parvovirus », « infection », « pregnancy », « hydrops ») appropriés. Les résultats ont été restreints aux analyses systématiques, aux essais comparatifs randomisés...

the reverse degree distance of a connected graph $g$ is defined in discrete mathematical chemistry as [ r (g)=2(n-1)md-sum_{uin v(g)}d_g(u)d_g(u), ] where $n$, $m$ and $d$ are the number of vertices, the number of edges and the diameter of $g$, respectively, $d_g(u)$ is the degree of vertex $u$, $d_g(u)$ is the sum of distance between vertex $u$ and all other vertices of $g$, and $v(g)$ is the ...

evaporation of micro-liter drops from solid surfaces at room condition is mainly governed by diffusion. therefore, there should be no difference between evaporation rate of sessile and pendant drops. however, some studies indicate a difference and explain the difference using buoyancy. the objective here is to reconcile the inconsistency in the literature. for that, first, by comparing two iden...

A simple, mild and convenient method has been developed for catalytic immobilisation of glucose oxidase (GOx), chemically modified to contain pendant methallylsilyl groups, on an untreated silica surface.
