Advanced Science, EarlyView.The ultrathin (2.5 nm) MXene film self‐assembled at liquid interfaces breaks the trade‐off between transparency (82.5 %) and photothermal conversion effect (DT∼25.1°C ± 2.9 °C) under 100 mW cm−2. After encapsulated by a slippery surface with low adhesion, this transparent film can be applied in smart windows, eyewear, and optical sensors to autonomous ...

Advanced Science, EarlyView.The dual‐phase iridium oxide catalyst was synthesized via a hard‐template‐assisted method, overcoming the conventional activity–durability trade‐off observed in Ir‐based catalysts. The HDP‐IrOx exhibits excellent catalytic activity and long‐term stability through the synergistic coupling between amorphous and crystalline phases, offering new insights ...

Multi‐Physical Field Modulated P‐Bit Device Based on VO2 Thin Film
Advanced Science, EarlyView.We have proposed a VO2‐based P‐bit device where synergistic multi‐physical field modulation enables real‐time tunability of randomness. Besides introducing a new phase‐change material‐based device approach for high‐performance P‐bits, this study also demonstrates a synergistic multi‐physical field modulation strategy that opens new opportunities for ...

Improved Molybdenum Dioxide Atomic Layer Deposition Process by Introducing Pre‐Reduction Agent
Advanced Electronic Materials, EarlyView.This study investigates MoO2 thin films deposited by ALD as electrode materials for next‐generation DRAM capacitors. A pre‐reduction step using ethanol is introduced to control the oxidation state of MoOx and to suppress surface morphology degradation.

Degradation Mechanisms of Rutile‐Type TiO2 Photoanodes during Photoelectrochemical Water Splitting
Advanced Energy Materials, EarlyView.Combining operando dissolution measurements with microscopy and spectroscopy characterizations, we reveal different degradation mechanisms of rutile‐type TiO2 photoanodes during photoelectrochemical water splitting. In acidic electrolytes, degradation is inhibited once TiO2 reaches saturation.
