Cyclic carbonate and polycarbonate have been selectively obtained with good conversion by coupling carbon dioxide with diglycidylether of bisphenol A. The ruthenium trichloride supported on tetraethylammonium bromide and ...

The catalytic hydrogenation of cinnamaldehyde employing H2 as the reductant was carried out under supercritical (sc) CO2, propane and other CO2 dense mixture, employing Pt supported on silica and high surface (HS) ceria. ...

Background: In mutualistic interactions of fleshy-fruited plants and seed-dispersing birds, dispersers act as natural selection agents on fruit display traits. Bird-mediated phenotypic selection on maternal and seed level ...

This work takes a stand on whether Wallace should be regarded as co-author of the theory of natural selection alongside Darwin as he is usually considered on behalf of his alleged essential contribution to the conception ...

The impact of solvent on Co(9.8%)/SiO2 activity and selectivity for the synthesis of n-butylamine from the liquid-phase butyronitrile hydrogenation was investigated at 373 K and 13 bar using methanol, benzene, toluene and ...

Zn-promoted Cu-ZSM-5 catalysts are active and selective for CO oxidation in the presence of H2. This high activity was attributed to the improved reducibility of copper species in exchanged samples.

This theoretical proposal applies evolutionary aesthetic, animal signalling and sexual selection to understand our artistic cognition, especially rock art aesthetics. Iconographic motifs, universally found in rock art, ...
