A newly engineered biochar material may offer a powerful and sustainable way to clean up toxic metals from polluted water and soil, according to a recent study published in Biochar.

Machining, involving the precise cutting and shaping of materials, is a key manufacturing process. As industries increasingly adopt the use of high-performance materials with high strength and hardness, traditional machining methods often fall short in delivering the required precision. A research team at The Hong Kong Polytechnic University (PolyU) has developed a ground-breaking machining technology that combines laser and magnetic fields during diamond cutting, enhancing cutting smoothness and surface quality while reducing a material’s subsurface damage and tool wear. This dual-field approach demonstrates exceptional manufacturing capabilities that surpass existing field-assisting cutting techniques, making possible ultra-precision machining of a range of challenging advanced materials.

As the world searches for scalable solutions to climate change, a growing body of research is highlighting biochar as a promising carbon-negative technology with far-reaching environmental benefits. A new comprehensive review published in Biochar explores how this carbon-rich material could help tackle global challenges ranging from greenhouse gas emissions to soil degradation and water pollution.

Researchers have developed a new class of sustainable energy storage materials by transforming agricultural waste into high-performance biochar composites that can store and release heat efficiently. The study demonstrates how simple changes in biomass type and production temperature can significantly improve energy storage capacity and durability, offering a promising pathway for low-carbon building technologies and renewable energy systems.

A new study shows that combining machine learning with advanced material engineering can significantly improve the performance of hydrochar, a carbon-rich material derived from waste, offering a promising pathway for sustainable agriculture and climate mitigation.

A new study reveals that adding small amounts of biochar, a carbon-rich material made from agricultural waste, can significantly improve the quality and performance of 3D-printed plastics while advancing more sustainable manufacturing practices.

Traditional electrolyte research has long centered on the solvation behavior of lithium-ions (cation), focusing on improving lithium ion transport dynamics by optimizing solvent or salt concentrations. As batteries evolve toward higher energy density, wider operation temperature ranges, and extended cycle lifespan, this “cation-centered” solvation approach has encountered limitations: unstable electrode/electrolyte interfaces, poor lithium-ion transport dynamics, and inadequate adaptation across broad temperature ranges. Unlike cations acting as passive charge carriers, anions become active regulators of electrolyte performance by modulating solvation structures, governing interfacial reactions, and optimizing transport mechanisms. Anion chemistry unlocks this active regulatory capability, offering more fundamental and comprehensive solutions for high-energy-density batteries electrolyte design.

Biochar is widely recognized as a promising material for improving soil health, cleaning contaminated water, and storing carbon. But scientists are increasingly focusing on a less visible feature inside biochar that may determine both its benefits and risks: persistent free radicals.
