Utilisant des approches divergentes, on a réalisé des synthèses de nouveaux mésogènes en forme étoilée à base d'acide trimésique et des portions centrales portant des chaînes latérales symétriques se terminant par des groupes alcoxy. Les portions centrales et les chaînes latérales sont liées ...

Membranes with exceptional pore regularity and high porosity were obtained from block copolymer solutions. We demonstrate by small-angle X-ray scattering that the order which gives rise to the pore morphology is already incipient in the casting solution. Hexagonal order was confirmed in ...

Supported metals are traditionally prepared by impregnating a support material with the metal precursor solution, followed by reduction in hydrogen at elevated temperatures. In this study, a polymeric support has been considered. Polypyrrole (PPy) has been chemically synthesized using FeCl3 ...

In this study, processed natural rubber latex was degraded in outdoor aquatic microcosms, under a number of treatment scenarios for 200 days. The analytical strategy adopted aimed to characterise a range of volatile, semi-volatile and non-volatile substances. Zinc, was shown to migrate from ...

Single crystalline gold nanoplates with size of micrometers and tens of nanometers in thickness were synthesized by reducing HAuCl4 with disodium salt of ethylenediaminetetraacetic acid (Na2EDTA) in the presence of hexadecyltrimethylammonium bromide (CTAB) in aqueous solution. The result ...

The sugar-modified Schiff-base ligands derived from benzyl 2-deoxy-2-salicylideneamino-α-D-glucopyranoside (H2L5-Br and H2L3-OMe) were used to prepare the chiral oxidovanadium(V) complexes [VO(L5-Br)(OMe)] (1) and [VO(L3-OMe)(OMe)] (2) which can be isolated from methanol solution as the ...

Hybrid photocatalysts consisting of single crystalline BiFeO3 nanowires and laser ablated Au nanoparticles were synthesized by a functionalization-step-free solution process. The 1.0 wt% Au nanoparticles decorated BiFeO3 nanowires exhibit ~30 times higher photocatalytic activity of water ...

We propose a fully quantitative theory for the finite-size scaling of the filling transition in a three-dimensional double wedge geometry, based on the exact transfer-matrix solution of a phenomenological interfacial model. Antisymmetric fields act at the top and bottom wedges; so each one ...
