Advanced Functional Materials, EarlyView.Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Solid Oxide Fuel Cell with Anodes using Proton Conductor (Barium-Cerium/Yttrium Oxide)
Journal of Thermal Science and Technology, 2009 A new anode with a proton conductor (Barium-Cerium/Yttrium oxide (BCY): BaCe0.8Y0.2O3-δ) was proposed for a high-power, solid-oxide fuel cell. In the new anode, the proton-conducting material was included in a conventional anode made of nickel (Ni)

Modulating Electrochemical CO2 Reduction Pathways via Interfacial Electric Field
Advanced Functional Materials, EarlyView.Engineering interfacial electric fields in Cu/ITO electrodes enables precise control of CO2 reduction pathways. Charge transfer from Cu to ITO generates positively charged Cu species that steer selectivity from ethylene toward methane. This work demonstrates how interfacial electric‐field modulation can direct reaction intermediates and transform ...
