Active Sites‐Enriched Hierarchical Weyl Semimetal WTe2 Nanowire Arrays for Highly Efficient Hydrogen Evolution Reaction

Advanced Science, EarlyView.
Weyl semimetal WTe2 possesses high conductivity and robust topological surface states. A controlled synthesis method for carbon fiber‐supported WTe2 and core–shell WO3−x–WTe2 nanowire arrays is proposed. The WTe2 nanowires are highly crystalline, uniform, and vertically aligned, providing abundant active sites and durability in hydrogen evolution ...

Large-amplitude chirped coherent phonons in tellurium mediated by ultrafast photoexcited carrier diffusion [PDF]

, 2010
We report femtosecond time-resolved reflectivity measurements of coherent phonons in tellurium performed over a wide range of temperatures (3K to 296K) and pump laser intensities. A totally symmetric A$_{1}$ coherent phonon at 3.6 THz responsible for the

Recent Advances in Xenes Based FET for Biosensing Applications

Advanced Science, EarlyView.
Xenes (monoelemental 2D materials like graphene, phosphorene, tellurene) enable ultrasensitive FET (Field‐Effect Transistor) biosensors due to their tunable bandgap, high carrier mobility, and large surface area. Advances in synthesis (CVD, MBE) and functionalization allow detection of DNA/RNA (via CRISPR‐Cas systems), proteins, small molecules, and ...

Improved Magnetoresistance of Tungsten Telluride and Silver Telluride Composites

Advanced Electronic Materials, EarlyView.
This study focuses on the composite magnetoresistive materials of tungsten telluride (WTe₂) and silver telluride (Ag₂Te). Bulk composites are prepared by using different contents of the second phase. Adding 10% silver telluride can enhance the magnetoresistance performance, reduce magnetic field and increase onset temperature.

Materials Selection Principles for Designing Electro‐Thermal Neurons

Advanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...
