Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Numerical Simulation and Analysis of Cycloidal Gear Forming Grinding Temperature Field

Jixie chuandong, 2018
Forming grinding process is one of the methods for finishing the cycloidal gear. When the grinding process parameters are not suitable,the instantaneous heat generated in the grinding zone will cause the tooth surface burn.

Surface Integrity and Subsurface Modification Depths During Grinding Under Varying Process Conditions

Metals
This study investigates the influence of the spatial distribution of specific grinding power within the contact zone on subsurface layer modification and the resulting modification depth effects. In surface grinding experiments on AISI 4140, the width of

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

Deep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...
