Ultrathin Co3O4 Layers Realizing Optimized CO2 Electroreduction to Formate.

Angewandte Chemie (International ed. in English)

Gao S, Jiao X, Sun Z, Zhang W, Sun Y, Wang C, Hu Q, Zu X, Yang F, Yang S, Liang L, Wu J, Xie Y.
PMID: 26783062
Angew Chem Int Ed Engl. 2016 Jan 11;55(2):698-702. doi: 10.1002/anie.201509800. Epub 2015 Nov 24.

Electroreduction of CO2 into hydrocarbons could contribute to alleviating energy crisis and global warming. However, conventional electrocatalysts usually suffer from low energetic efficiency and poor durability. Herein, atomic layers for transition-metal oxides are proposed to address these problems through...

CeNbO4.25 is reported to exhibit fast oxygen ion diffusion at moderate temperatures, making this the prototype of a new class of ion conductor with applications in a range of energy generation and storage devices. To date, the mechanism by...

How the thermocline affects the value of the waveguide invariant in a shallow-water waveguide.

The Journal of the Acoustical Society of America

Adv Mater. 2017 Apr;29(16). doi: 10.1002/adma.201605166. Epub 2017 Feb 24.

This study demonstrates a facile way to efficiently induce strong memory behavior from common p-type conjugated polymers by adding n-type dopant 2-(2-methoxyphenyl)-1,3-dimethyl-2,3-dihydro-1H-benzoimidazole. The n-type doped p-channel conjugated polymers not only enhance n-type charge transport characteristics of the polymers, but...

Electromagnetically-induced-transparency-based four-wave mixing (FWM) in a resonant four-level double-Λ system has a maximum conversion efficiency (CE) of 25% due to spontaneous emission. Herein, we demonstrate that spontaneous emission can be considerably suppressed by arranging the applied laser beams in...
