As the world transitions towards renewable energy, the demand for safe, cost-effective, and environmentally friendly energy storage solutions has become paramount. Zinc-ion energy storage devices (ZESDs), including batteries and capacitors, have emerged as a highly promising alternative to conventional lithium-ion technologies due to the natural abundance and low toxicity of zinc. A new review published in Carbon Research provides a systematic overview of the critical role that carbon materials play in advancing these sustainable technologies. The work, authored by a team from Changsha University of Science and Technology, Sichuan University, and Xiamen University, consolidates the latest strategies for using carbon to enhance every component of ZESDs, from the cathode to the notoriously problematic zinc anode.

By introducing fairness from the beginning with ‘fuzzy’ systems that understand ambiguity and shades of correctness, the evolved AIs balanced fairness and accuracy even when tasked with coming up with solutions for complicated financial and ethical issues.

In a novel approach that bridges sustainable agriculture and climate technology, scientists have successfully used cow manure as a superior, green alternative to chemical additives for creating high-performance carbon-capture materials. A collaborative team from the Chinese Academy of Agricultural Sciences (CAAS) and China Agricultural University has demonstrated that protein-rich cow manure is more effective than conventional urea for producing nitrogen-doped biochar, a porous material designed to adsorb CO₂ from the atmosphere. This finding presents a dual solution, tackling agricultural waste management while advancing carbon capture technology.

The research, led by Yuxuan Sun, Jixiu Jia, and Zonglu Yao, focused on developing a more environmentally friendly method for enhancing biochar. The standard process often relies on synthetic, energy-intensive nitrogen sources like urea to improve biochar’s ability to trap CO₂ molecules. The team instead explored a circular-economy model, using corn straw as the base carbon material and cow manure as a biological nitrogen source. They prepared different biochar samples through hydrothermal carbonization, a process that uses heated water under pressure, followed by a potassium hydroxide activation step to create a highly porous final product.

Researchers from the FAMU-FSU College of Engineering and the Florida Center for Advanced Aero-Propulsion, or FCAAP, are helping to solve a safety challenge in military aviation: the extreme noise generated by supersonic jets during takeoff and landing.

The research, published in the Journal of Fluid Mechanics, demonstrates a new model for understanding how supersonic jets of air collide with the ground or other structures to create a resonant feedback loop that produces extreme noise that can reach dangerous volume levels.

A new study published in Big Earth Data proposes an AI cube framework that integrates GeoAI models into geospatial data cube infrastructures to enhance large-scale Earth Observation data analytics. By introducing a model warehouse, intelligent model selection, and parallel inference pipelines on the Open Geospatial Engine platform, the approach significantly improves analytical capability and reduces inference time by over 80%. The framework advances the transition from traditional data cube processing toward AI-ready spatial data infrastructures.

A team of scientists from the State Key Laboratory of Biogeology and Environmental Geology, China University of Geosciences, has introduced an economical and environmentally friendly approach for cleaning antibiotic-contaminated water. The work, led by authors Jingqi Wu and Jiawei Chen, focuses on enhancing a carbon material called hydrochar, derived from the noxious invasive water hyacinth plant. By applying a simple mechanical grinding process, the team was able to nearly triple the material's capacity to adsorb the common antibiotic norfloxacin, presenting a promising new avenue for water remediation.

China’s ambitious “Dual Carbon” initiative, aiming for carbon dioxide emissions to peak before 2030 and achieve carbon neutrality by 2060, necessitates a profound transformation across all sectors. A recent perspective paper explores the significant role of forestry in this national endeavor, detailing its potential to enhance carbon sequestration while addressing developmental challenges. The analysis, conducted by researchers at Foshan University, University of Western Australia, and the Guangdong Academy of Sciences, offers a strategic blueprint for leveraging forest resources as a low-cost carbon sink for global climate change mitigation.

Researchers have unveiled crucial details about how a common freshwater bacterium, Methylobacter sp. YHQ, manages the delicate balance of carbon and nitrogen biogeochemical cycles. This investigation, published in Carbon Research, utilized dual nitrogen-oxygen (N-O) isotope analysis and kinetic modeling to illuminate the enzymatic processes of assimilatory nitrate reduction and methane oxidation, offering a novel "fingerprint" to differentiate microbial nitrogen-cycling enzymes and providing a powerful quantitative tool for environmental management.
