A Researcher team at the Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed a technology that converts wet spent coffee grounds directly into high-quality biochar in just 90 seconds, no drying or oil removal required. The breakthrough offers a fast, energy-efficient path to turning high-moisture organic waste into valuable fuel and carbon materials.

The study, led by Dr. Taejun Park in collaboration with GodTech Co., Ltd., was published in the Chemical Engineering Journal (Elsevier), one of the world's leading journals in chemical engineering.

Researchers from Tongji University present a comprehensive review of emerging optical techniques for sorting and detecting chiral particles. The review highlights advances in engineered light fields, nanophotonic platforms, and artificial intelligence that enhance the sensitivity, selectivity, and efficiency of chiral analysis. By comparing optical sorting and detection strategies across diverse platforms, the work outlines current challenges and future directions, providing a valuable roadmap for developing practical, high-performance optical technologies for chemistry, biomedicine, and materials science.

Expected to serve as core AI data infrastructure across industries such as finance, law, and manufacturing, improving enterprise AI agent accuracy by up to 78% and processing speed by up to 20 times

Peatlands store vast amounts of carbon, but when they are drained for agriculture, they can become major sources of greenhouse gases. Restoring water levels can slow carbon dioxide emissions, yet overly wet peat can produce methane, a powerful greenhouse gas. This creates a difficult climate dilemma: how can peatlands be managed to protect soil carbon without triggering high methane release?

Paddy soils are living chemical reactors. Under flooded and drained conditions, microbes, minerals, oxygen, and organic matter constantly exchange electrons, shaping how pollutants move, transform, or disappear. A new study published in Biochar reports that a specially engineered form of biochar can redirect these electron flows, helping paddy soils generate more hydroxyl radicals, one of nature’s most powerful oxidants, and break down the antibiotic sulfamethoxazole more efficiently.

Microalgae have long been viewed as a promising source of renewable fuel. They grow quickly, capture carbon dioxide efficiently, and do not compete with food crops for farmland. Yet turning algae into usable liquid fuels remains difficult because algae-derived bio-oil often contains high levels of oxygen and nitrogen compounds, which can lower fuel quality, reduce stability, and create pollution concerns during combustion.
