Decoupling Stable Cyclic Deformation From Defect Accumulation in Metals

Advanced Science, EarlyView.
Introducing amorphous nanoparticles into a metal matrix enables a cyclic deformation regime where strain hardening and defect accumulation are decoupled. These nanoparticles act as dislocation sinks and undergo reversible shear transformations, sustaining microstructural stability over millions of cycles.

Enhanced Hydrogen Evolution Activity of MoS2 Through Solid Solution Modification of Its Edge Sites With Ruthenium

Angewandte Chemie, EarlyView.
Modulating the edge sites of molybdenum disulfide significantly boosts hydrogen production. By depositing Ru to form an edge‐coordinated solid solution, we accelerate water dissociation and shift the hydrogen evolution reaction pathway to Volmer–Tafel.

System level simulation of passive and active backscatter devices [PDF]

, 2018
Ambient Backscatter is a communications method for batteryless, carrier-powered radio devices which harvest the needed energy from ambient sources and send their information by backscattering the ambient radio signals. An ambient backscatter device sends

Noncoherent Frequency-Shift Keying for Ambient Backscatter Over OFDM Signals

IEEE Open Journal of the Communications Society
In this paper, we investigate frequency shift keying (FSK) over ambient orthogonal frequency division multiplexed (OFDM) signals. By cycling through a sequence of antenna loads providing different phase shifts at the tag, we are able to unidirectionally ...

The Impact of Cobalt Substitution on the Electrochemical Properties of Cubic Li6.6La3Zr1.6Ta0.4O12 Solid Electrolyte for All‐Solid‐State Li‐Ion Batteries

Advanced Science, EarlyView.
Cobalt is incorporated more readily into garnet Li6.6La3Zr1.6Ta0.4O12 when sintered in argon than in air. Under argon, Co in the garnet lattice lowers the total conductivity three‐ to fourfold; in air, Co segregates as LiCoO2 and raises the electronic conductivity about 100‐fold instead.

Coexistence of Large Nernst Effect and Axis‐Dependent Conduction Polarity in Semimetal MoSi2

Advanced Electronic Materials, EarlyView.
MoSi2${\rm MoSi}_2$ is a rare material in which axis‐dependent conduction polarity (ADCP) and a large ordinary Nernst effect (ONE) coexist. The pronounced ONE (199μVK−1$199\,\umu \mathrm {V}\,\mathrm {K}^{-1}$) originates from nearly perfect carrier compensation, high mobility, and likely phonon drag, while ADCP arises from mixed‐dimensionality of the ...

Colossal Modulation of Mechanical Resonance with temperature in single‐Crystalline SrTiO3 Microbridges Integrated on Silicon

Advanced Electronic Materials, EarlyView.
The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

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 ...
