Abstract The lithium–sulfur (Li–S) battery is widely regarded as a promising energy storage device due to its low price and the high earth‐abundance of materials employed. However, shuttle effect lithium polysulfides (LiPSs) sluggish redox conversion result in inefficient sulfur utilization, power density, rapid electrode deterioration. Herein, these challenges are addressed with two strategies 1) increasing LiPS kinetics through catalysis, 2) alleviating by enhanced trapping adsorption...
Despite the tremendous progress of coupling organic electrooxidation with hydrogen generation in a hybrid electrolysis, electroreforming raw biomass coupled to green has not been reported yet due rigid polymeric structures biomass. Herein, we electrooxidize most abundant natural amino biopolymer chitin acetate over 90% yield electrolysis. The overall energy consumption electrolysis can be reduced by 15% thermodynamically and kinetically more favorable oxidation water oxidation. In obvious...
Abstract The ability to achieve dual‐mode thermal regulation for switchable heating and cooling on a single platform has thus far been challenged by the availability of suitable materials. materials need possess both high solar reflectance transmittance, necessitating large small thicknesses in same coating layer, respectively (i.e., thickness constraint). Herein, first time, single‐layer made facile one‐step process is reported, which exhibits rapid switch between reflection (≈96.6%)...
Abstract Transition metal oxides hold great promise for lithium‐ion batteries (LIBs) and electrocatalytic water splitting because of their high abundance energy density.

Abstract Alkaline water electrolysis (AWE) holds great promise for a truly sustainable energy future if it can be driven by renewable sources such as solar and wind. The main challenge arises from the serious partial loading issue when intermittent unstable is coupled to electrolyzers. An storage device mitigate this incompatibility between electrolyzer sources.

Investigations on external electrostatic field (EEF)-enhanced liquid water evaporation have been reported decades ago, which suggest that molecular alignment and polarization tuned by EEF accelerating the phase change process could be responsible for EEF-enhanced evaporation. However, a detailed study revealing role of in altering intermolecular intramolecular structure is lacking. Herein, an proved to tune state thermal movement molecules, lowering escaping energy, loosening hydrogen bond...
Abstract Arbitrary disposal of plastic waste into landfills and oceans can disturb the ecological system even challenge human survival. Centralized recycling process only works for selected types plastics (e.g., polyethylene) with limited contribution (<10%), because high infrastructure requirement. Comparatively, photoreforming commodity fuels production is much more facile decentralizable, thus holds great potential to mitigate challenge. To this end, a fully solar powered...
