Engineering Bulk Photovoltaic Effect in 2D Transition Metal Dichalcogenides

Advanced Science, EarlyView.
Structural and phase engineering in two‐dimensional transition metal dichalcogenides (2D TMDs), through lattice distortion, phase transitions, and polarization modulation, to induce the bulk photovoltaic effect (BPVE) for optoelectronic and energy conversion applications.

Berry-phase effects and electronic dynamics in noncollinear antiferromagnetic texture

, 2015
Antiferromagnets (AFMs), in contrast to ferromagnets, show a nontrivial magnetic structure with zero net magnetization. However, they share a number of spintronic effects with ferromagnets, including spin-pumping and spin transfer torques. Both phenomena

Intrinsic Strain‐Driven Topological Evolution in SrRuO3 via Flexural Strain Engineering

Advanced Electronic Materials, EarlyView.
A flexural strain platform is developed to isolate intrinsic strain effects on the topological electronic structure in SrRuO3, and demonstrates that the topological properties and associated anomalous Hall effect can be effectively modulated via strain engineering without introducing phase transitions or crystal defects, offering a new approach for ...

Berry Phases on Virasoro Orbits

, 2017
We point out that unitary representations of the Virasoro algebra contain Berry phases obtained by acting on a primary state with conformal transformations that trace a closed path on a Virasoro coadjoint orbit.

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

Advanced Energy Materials, EarlyView.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.

Berry Curvature, Triangle Anomalies, and the Chiral Magnetic Effect in Fermi Liquids

, 2012
In a three-dimensional Fermi liquid, quasiparticles near the Fermi surface may possess a Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a ...

Grave to Cradle: A Direct Recycling Approach for Over‐Discharged LiFePO4 Electric Vehicle Cells

Advanced Energy and Sustainability Research, EarlyView.
The change in the LiFePO4 (LFP) material from grave to cradle. The material is delaminated with water, before undergoing ball milling and a relithiation‐carbothermal treatment. The final step shows the fully healed LFP remanufactured as a new cathode. The purple represents LiFePO4, the light purple FePO4, black, and dark grey—the graphite and carbons ...

Food Tastes in the United States: Convergence or Divergence?

Agribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.
