Robustness of Half‐Metallicity and Spin‐Dependent Transport in Defective Co2HfSn and Co2ZrSn Heusler Alloys

Advanced Electronic Materials, EarlyView.
Point defects strongly influence the spin‐dependent electronic and transport properties of Co2HfSn and Co2ZrSn Heusler alloys. First‐principles calculations reveal that Co vacancies preserve half‐metallicity, while anti‐site and swap defects introduce minority‐spin states that reduce spin selectivity.

3D MXene Aerogel Frameworks With In Situ‐Grown BiFeO3 for Synergistically Enhanced Thermoelectric Performance

Advanced Electronic Materials, EarlyView.
A lightweight, 3D MXene aerogel framework integrated with bismuth ferrite was developed to efficiently harvest waste heat. By growing the oxide directly onto the porous aerogel, the composite achieves strong interfacial connections. This unique architecture simultaneously boosts electrical power generation and blocks heat flow, resulting in an ...

Advancing Energy Materials by In Situ Atomic Scale Methods

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

Advanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...
