Structure–property insights into nanostructured electrodes for Li-ion batteries from local structural and diffusional probes [PDF]

open access: yes, 2018
Microwave heating presents a faster, lower energy synthetic methodology for the realization of functional materials. Here, we demonstrate for the first time that employing this method also leads to a decrease in the occurrence of defects in olivine ...

Synthesis of Schiff Bases via Environmentally Benign and Energy-Efficient Greener Methodologies

open access: yesE-Journal of Chemistry, 2009
Non classical methods (water based reaction, microwave and grindstone chemistry) were used for the preparation of Schiff bases from 3-chloro-4-fluoro aniline and several benzaldehydes. The key raw materials were allowed to react in water, under microwave

Microwave-assisted YBa2Cu3O7 precursors : a fast and reliable method towards chemical precursors for superconducting films [PDF]

open access: yes, 2017
Highly stable, pure, and anhydrous organometallic YBa2Cu3O7- (YBCO) precursor solutions were prepared by dissolving commercial YBCO powder in acetone by trifluoroacetic anhydride (TFAA) or a mixture of TFAA with propionic acid for low fluorine precursors.
