Synergistic effect of p-type and n-type dopants in semiconductors for efficient electrocatalytic water splitting.

The main challenge for acidic water electrolysis is the lack of active and stable oxygen evolution catalysts based on abundant materials, which are globally scalable. Iridium oxide is the only material which is active and stable. However, Ir is extremely rare.

Lifting the discrepancy between experimental results and the theoretical predictions for the catalytic activity of RuO(110) towards oxygen evolution reaction.

Developing new efficient catalyst materials for the oxygen evolution reaction (OER) is essential for widespread proton exchange membrane water electrolyzer use. Both RuO(110) and IrO(110) have been shown to be highly active OER catalysts, however DFT predictions have been unable to explain the high activity of RuO. We propose that this discrepancy is due to RuO utilizing a different reaction pathway, as compared to the conventional IrO pathway.

Oxygen evolution reaction: a perspective on a decade of atomic scale simulations.

Multiple strategies to overcome the intrinsic limitations of the oxygen evolution reaction (OER) have been proposed by numerous research groups. Despite the substantial efforts, the driving force required for water oxidation is largely making the reaction inefficient. In the present work, we collected published studies involving DFT calculations for the OER, with the purpose to understand why the progress made so far, for lowering the overpotential of the reaction, is relatively small.

Chitosan-co-Hyaluronic acid porous cryogels and their application in tissue engineering.

In this work, the usability of chitosan-co-hyaluronic acid cryogels as a tissue-engineering scaffold was investigated. Chitosan-co-hyaluronic acid cryogels were synthesized at subzero temperature. Cryogels which were composed of various compositions of chitosan and hyaluronic acid (0, 10, 20, 30 and 50wt% hyaluronic acid) was prepared.
