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

open access: yesEcoEnergy, 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.

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

Defect Engineering and Effect of Vacancy Concentration on the Electrochemical Performance of V‐Based MXenes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a top‐down defect engineering approach, controllable vacancy concentrations are introduced into V‐based MXenes by rationally designing the precursor MAX phase, aiming to investigate the effect of vacancy concentration on the electrochemical performance.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two
