Microwave-induced Hall resistance in bilayer electron systems [PDF]

open access: yes, 2011
The influence of microwave irradiation on dissipative and Hall resistance in high-quality bilayer electron systems is investigated experimentally. We observe a deviation from odd symmetry under magnetic field reversal in the microwave-induced Hall ...

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
