High‐Performance Solar‐Thermal Hydrogel Based on Waste Biomass Materials for Power Generation and Water Purification

EcoEnergy, EarlyView.
An environmentally friendly and highly efficient solar evaporator was constructed using waste biomass materials and polyvinyl alcohol carrier, which achieves an outstanding evaporation rate of 1.48 kg m−2 h−1, corresponding to an energy conversion efficiency of 82.49% under 1.0 kW m−2 simulated sunlight irradiation.

Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Self‐Maintained Thermal Charging Cells for the Efficient Harvesting of Waste Heat at Elevated Temperatures

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Thermal charging cells (TCS) face two main challenges that limit their practical applications: 1) Still lacking the systems suitable for operation under higher temperature environments, and 2) there are limitations in the self‐sustaining performance of continuous discharge under temperature differences, which holds critical significance for the real ...
