Polyoxometalate-HKUST-1 composite derived nanostructured Na-Cu-MoC catalyst for efficient reverse water gas shift reaction.

Transforming CO to CO reverse water-gas shift (RWGS) reaction is widely regarded as a promising technique for improving the efficiency and economics of CO utilization processes. Moreover, it is also considered as a pathway towards e-fuels. Cu-oxide catalysts are widely explored for low-temperature RWGS reactions; nevertheless, they tend to deactivate significantly under applied reaction conditions due to the agglomeration of copper particles at elevated temperatures.

Correlation between alignment geometries and memory effect in a surface-stabilized ferroelectric liquid crystal.

Memory effect in weakly aligned surface stabilized ferroelectric liquid crystal (SSFLC) material has been investigated by electro-optical and dielectric spectroscopy in three configurations of alignment: antiparallel, 90^{∘} twisted, and unaligned planar samples.
