Dielectric and Electromagnetic Attenuated Properties of WC/Wax Composite

Frontiers in Materials, 2020
In this study, tungsten carbide (WC) microparticles with different sizes were synthesized by the heating-programmed temperature method. Tungsten carbide produces obvious resonance peaks at intermediate and high frequencies, which contribute to ...

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Critical mineral removal from mining‐impacted waters using microalgal biomass

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

Processing of complex near-net-shaped tungsten parts by PIM

Nuclear Materials and Energy, 2018
Powder Injection molding (PIM) as near-net-shape technology allows the effective mass fabrication of complex tungsten parts. Depending on the size and shape of the parts, for simple geometries only 20 s needed to produce a part.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Dynamic Reconstruction of Interfacial Hydrogen‐Bond Networks Enhances CO2 Electroreduction Selectivity

EcoEnergy, EarlyView.
Concentrated NaClO4 dynamically reconstructs interfacial hydrogen‐bond networks during CO2 electroreduction, restricting proton transport and stabilizing CO‐derived intermediates. Multinuclear NMR, infrared spectroscopy, and simulations reveal electrolyte‐mediated electric‐double‐layer regulation, which suppresses hydrogen evolution and enhances C–C ...

Near‐Infrared Light‐Driven Photocatalysis: From Advanced Light‐Harvesting Architectures to Rational Reactor Design

EcoEnergy, EarlyView.
This review systematically elucidates the regulatory strategies for NIR light, encompassing macroscopic mechanisms such as band engineering, localized surface plasmon resonance (LSPR), upconversion luminescence, and photosensitizer molecules. Furthermore, it provides an in‐depth discussion on their cutting‐edge applications in energy conversion (e.g ...

2D/2D/2D Metallic 1T Phase WS2/TiO2/Ti3C2Tx MXene Ternary Composite for Synergistically Enhanced N2 Electroreduction

EcoEnergy, EarlyView.
TiO2 nanosheets were in situ grown on Ti3C2Tx MXene, and then 1T phase WS2 was distributed on TiO2/Ti3C2Tx MXene to form 1T‐WS2/TiO2/Ti3C2Tx MXene, which exhibits a prominent NH3 yield of 46.27 μg h−1 mg−1cat. at −0.8 V versus RHE and a superior FE of 69.26% at −0.65 V versus RHE.
