Adsorption of Carbon Dioxide in Several Aged Hydrotalcites and Calcined Hydrotalcites: Influence of Microwave Irradiation during the Ageing Step on Their Basic Properties

open access: yesAdsorption Science & Technology, 2007
Several Ni/Mg/Al hydrotalcites were aged by autoclaving under microwave irradiation, refluxing under microwave irradiation and by traditional refluxing methods. The hydrotalcite aged by autoclaving under microwave irradiation at a higher temperature (453

Microwave Irradiation: Alternative Heating Process for the Synthesis of Biologically Applicable Chromones, Quinolones, and Their Precursors

open access: yesMolecules, 2021
Microwave irradiation has become a popular heating technique in organic synthesis, mainly due to its short reaction times, solventless reactions, and, sometimes, higher yields.

FASTER PLASTICIZERS PRODUCTION BY MICROWAVE IRRADIATION

open access: yesProceedings 17th International Conference on Microwave and High Frequency Heating, 2019
Plasticizers are esters used to confer plasticity to polymer goods. They are prepared by esterification between a carboxylic acid or anhydride and a heavy alcohol. Esterification is a very slow reaction and its batches may last more than 12 hours of processing [1].

Superconducting Atomic Contacts under Microwave Irradiation [PDF]

open access: yesPhysical Review Letters, 2006
We have measured the effect of microwave irradiation on the dc current-voltage characteristics of superconducting atomic contacts. The interaction of the external field with the ac supercurrents leads to replicas of the supercurrent peak, the well known Shapiro resonances.
