Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

open access: yesElectron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

open access: yesSmall, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

Distinct Solvent Effects on Dispersibility and Photoinduced Hydrogen Release of Hydrogen Boride Sheets

open access: yesSmall, EarlyView.
Hydrogen boride (HB) sheets exhibit strongly solvent‐dependent dispersion and photoinduced hydrogen release. HB‐sheet dispersibility depends on solvent‐dependent interactions, whereas hydrogen release is more strongly associated with the hydrogen‐bonding character of the solvent.

Bimetallic Zn/Cu Metal–Organic Framework (MOF)/ Two‐Dimensional i‐MBene Hybrid Electrodes for Enhanced Supercapacitor Performance

open access: yesSmall, EarlyView.
A Zn/Cu MOF–i‐MBene hybrid electrode (ZC‐MYB) for supercapacitors is developed. The composite retained 81% of its specific capacitance after 9000 cycles, increasing it by 46% over ZC MOF and 5.6‐fold over i‐MBene. At 2 mV/s, the asymmetric ZC‐MYB/AC device produced 73.4 F/g.

Superconducting borides [PDF]

open access: yesAIP Conference Proceedings, 1991
A number of superconductors are found among binary and ternary boride compounds. The highest {Tc}'s are often fund near a limiting composition for the compound's stability. Ternary borides have been a fertile area for exploring the interaction between superconductivity and magnetism, and appear to be the area in which further aspects of boride ...

An Extensive Study of the Production of Hydrogen by Cellulose and Lignin Pyrolysis Using Rhenium-Based Catalysts

open access: yesChemistry
The use of rhenium-based catalysts (Re2C, Re3B, ReB2, and ReS2) obtained by mechanosynthesis in the pyrolysis of cellulose and lignin from 500 to 800 °C using 10 and 20 wt.% of catalysts is reported. The mechanosynthesis of ReS2 has been reported for the
