No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Chemoselectivity and Enantioselectivity in the Conjugate Reduction of Cinnamate Esters and a Tandem Conjugate Reduction‐Ester Hydrogenation Using Manganese Catalysts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An improved synthesis of a manganese catalyst used for hydrogenation of ketones, esters and imines is reported. The catalyst has now been found to effect tandem conjugate reduction‐ester hydrogenations with very low amounts of allylic alcohol by‐products.

The Effect of the Gem‐Dimethyl Unit in the Gold‐Catalyzed Cycloisomerization of Aliphatic 1‐Bromoalkynes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The conformational effect of the gem‐dimethyl motif and its isostere cyclopropane unit in the gold‐catalyzed cycloisomerization of aliphatic 1‐bromoalkynes has been studied. An unexpected inhibitory effect of the cyclopropane ring has been observed.
