Optical analysis of CH3NH3SnxPb1−xI3 absorbers: a roadmap for perovskite-on-perovskite tandem solar cells

Nov 26, 2016 | Sin categoría

Organic–inorganic perovskite structures in which lead is substituted by tin are exceptional candidates for broadband light absorption. Herein we present a thorough analysis of the optical properties of CH3NH3SnxPb1−xI3films, providing the field with definitive...

Gold promoted Cu/ZnO/Al2O3 catalyst prepared from hydrotalcite precursors: Advanced materials for the WGS reaction

Oct 26, 2016 | Sin categoría

Outstanding catalysts for the water was shift reaction are reported in this work. The combination of gold nanoparticles with Cu/ZnO/Al2O3 prepared from hydrotalcite-like precursors leads to very promising systems for pure hydrogen production. Full CO conversion is...

Mechanistic Studies on the Selective Reduction of CO2 to the Aldehyde Level by a Bis(phosphino)boryl (PBP)-Supported Nickel Complex

Sep 26, 2016 | Sin categoría

This work describes a thorough investigation of the mechanism of a highly selective hydrosilylation of CO2 to the formaldehyde level catalyzed by a bis(phosphino)boryl(PBP)Ni(II) complex in the presence of B(C6F5)3. CO2 activation by insertion into the Ni–H bond of...

Glucose–Nucleobase Pseudo Base Pairs: Biomolecular Interactions within DNA

Ago 26, 2016 | 2016, 2016, 2016, 2016, 2016, 2016

Noncovalent forces rule the interactions between biomolecules. Inspired by a biomolecular interaction found in aminoglycoside–RNA recognition, glucose-nucleobase pairs have been examined. Deoxyoligonucleotides with a 6-deoxyglucose insertion are able to hybridize with...

The selective reduction of CO2 to the formaldehyde level remains an important challenge and to date only a few catalysts have been developed for this reaction. Herein, we report an efficient catalyst that consists of a bis(phosphino)boryl nickel hydride complex...

The chloroplast NADPH thioredoxin reductase C, NTRC, controls non-photochemical quenching of light energy and photosynthetic electron transport in Arabidopsis

Jun 26, 2016 | Sin categoría

High irradiances may lead to photooxidative stress in plants, and non-photochemical quenching (NPQ) contributes to protection against excess excitation. One of the NPQ mechanisms, qE, involves thermal dissipation of the light energy captured. Importantly, plants need...
