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.

Enantioselective Esterification of Ibuprofen under Microwave Irradiation [PDF]

open access: yesMolecules, 2013
Enantioselective esterification of ibuprofen has been successfully carried out in an organic solvent catalyzed by recombinant APE 1547 (a thermophilic esterase from the archaeon Aeropyrum pernix K1). Here we used microwave irradiation (MW) as the mode of heating to improve the enzyme performance. Under the optimum conditions, the enzyme activity of APE
