Lattice Dynamics of Rutile Germanium Dioxide (r‐GeO2)

Advanced Electronic Materials, EarlyView.
The rutile polymorph of GeO2 is a promising ultra‐wide bandgap material, but key properties for its technological exploitation remain poorly understood. Using polarization angle‐resolved Raman spectroscopy, we resolve long‐standing uncertainties in the energies of Raman‐active phonons and extract relative Raman tensor elements.

High‐Performance and Energy‐Efficient Sub‐5 nm 2D Double‐Gate MOSFETs Based on Silicon Arsenide Monolayers

Advanced Electronic Materials, EarlyView.
Sub‐5 nm double‐gate MOSFETs based on 2D SiAs monolayers are investigated using quantum transport simulations. By engineering source‐drain underlap regions, the devices achieve exceptional on‐currents of up to 1206 µA µm−1, surpassing the ITRS 2028 high‐performance targets.

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, EarlyView.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Atomic Scale Ordering of Liquid Water at a Dynamic Pt(111) Interface Under Electrochemical Conditions Imaged by Electron Holography

Advanced Energy Materials, EarlyView.
High resolution electron holography was used to image the projected electric potential of ordered water layers at the interface to a platinum (111) electrode. The observed reorganization of the water layers upon applying external potentials suggests that the electric potential drop of the electric double layer is mainly carried by the polarization ...

Integrated Experimental and Theoretical Insights into Defect‐Induced Functionalities of Cobalt Doped NiO for Multifunctional Solar‐Driven Applications

Advanced Energy and Sustainability Research, EarlyView.
Rational defect engineering in Co‐doped NiO nanostructures, synthesized via a sustainable green route, enables precise bandgap modulation and defect‐state tailoring. Combined experimental–density functional theory analysis identifies 15% Co doping as the optimal threshold for maximizing photocatalytic degradation, photothermal response, and hydrogen ...

A Machine Learning Perspective on the Brønsted–Evans–Polanyi Relation in Water‐Gas Shift Catalysis on MXenes

Advanced Intelligent Discovery, EarlyView.
Machine learning predicts activation energies for key steps in the water‐gas shift reaction on 92 MXenes. Random Forest is identified as the most accurate model. Reaction energy and reactant LogP emerge as key descriptors. The approach provides a predictive framework for catalyst design, grounded in density functional theory data and validated through ...
