Separating bulk and surface processes in NiOx electrocatalysts for water oxidation
(Royal Society of Chemistry, 2020-08-10)
Nickel oxide-based catalysts currently represent the state of the art in electrochemical water oxidation in alkaline pH. However, much of their functionality remains poorly understood, particularly regarding catalytically ...
Transfer hydrogenations catalyzed by streptavidin-hosted secondary amine organocatalysts
(Royal Society of Chemistry, 2021-02-21)
Here, the streptavidin–biotin technology was applied to enable
organocatalytic transfer hydrogenation. By introducing a biotintethered pyrrolidine (1) to the tetrameric streptavidin (T-Sav), the
resulting hybrid catalyst ...
Towards highly efficient continuous-flow catalytic carbon dioxide cycloadditions with additively manufactured reactors
(The Royal Society of Chemistry, 2022-03-22)
Developing efficient and sustainable methodologies to transform CO2 into added-value chemicals is an important strategy for decarbonization in the chemical industry. Here, a new multi-scale approach for the cycloaddition ...
Interfacial Mechanism for Efficient Resistive Switching in Ruddlesden-Popper Perovskites for Non-volatile Memories
(American Chemical Society, 2020-01-16)
Ion migration, one origin of current–voltage hysteresis, is the bane of halide perovskite optoelectronics. Herein, we leverage this unwelcome trait to unlock new opportunities for resistive switching using layered ...
Mechanistic studies of a lipase unveil effect of pH on hydrolysis products of small PET modules
