A New Memory Effect in Bulk Crystals of 1T‐TaS2

Advanced Functional Materials, EarlyView.
A new memory effect is discovered in 1T‐TaS₂, appearing as a temperature shift in the metal to insulator transition, coinciding with the recently reported ramp reversal memory. These findings imply that ramp reversal memory is an emergent phenomenon, likely to appear in many different systems that share a few basic properties, which are discussed in ...

Reversible Phase Transitions Enable Cyclic Isothermal CO2 Capture in Redox‐Activated Perovskite‐Structured Sorbents

Advanced Functional Materials, EarlyView.
Perovskite‐structured SrMnO3 can cyclically and reversibly capture and release CO2 via redox‐enabled phase transitions at constant temperature. The efficacy of this novel redox‐activated CO2 sorbent is demonstrated via sorption‐enhanced steam methane reforming.

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

Advanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.
