Professor Jiang Chunhai (Xiamen University of Technology) and Professor Qiao Yu (Xiamen University) studied the compatibility of typical G2, G3, and G4 ether solvents with Li-metal anode under harsh O₂ environment from the perspectives of Li/Li symmetric batteries and Li-O₂ batteries. The experimental results indicate that G2 solvent helps enhance the cycling stability of Li/Li symmetric batteries, while G4 solvent is more conducive to promoting the reaction reversibility of Li-O₂ batteries.

Researchers have developed a membrane-separated differential electrochemical mass spectrometry (MDEMS) system that enables long-term gas evolution analysis in batteries using volatile electrolytes. By incorporating a graphene oxide-based membrane that selectively blocks organic solvent molecules while allowing gases to pass, the team overcame key limitations of traditional DEMS, which often fail within days due to solvent evaporation and interference. Applying this technique, they uncovered how electrolyte additives and cathode coatings interact to suppress gas-generating side reactions in lithium-ion batteries, providing new insights for extending battery life, especially at high temperatures.

Boosting Biochar's Versatility

Biochar, a carbon-rich material derived from biomass, holds immense promise as a sustainable and renewable resource for diverse applications, from environmental remediation to energy storage. However, its widespread utility has often been hampered by inherent limitations such as low porosity and insufficient surface functionality. These properties are crucial for effective interaction with pollutants, catalytic reactions, and energy storage mechanisms, impacting how efficiently biochar can perform in real-world scenarios.

Engineered nanomaterials (ENMs)—microscopic particles designed for use in everything from cosmetics and medicine to environmental cleanup—are becoming increasingly common. While their unique properties offer significant benefits, their inevitable release into the environment poses potential risks to ecosystems and human health. A comprehensive review published in Carbon Research summarizes the critical and complex role that dissolved organic matter (DOM), a ubiquitous natural substance, plays in determining the fate and impact of these nanomaterials.

Industrial processes often release volatile organic compounds (VOCs) into the atmosphere, posing significant risks to human health and the environment. Ethyl acetate, a common VOC used in paints, printing, and pharmaceuticals, contributes to the formation of smog and can cause health issues ranging from dizziness to cancer. Developing effective and energy-efficient methods to remove these pollutants is a critical environmental challenge. Traditional methods often require high temperatures, making them costly and energy-intensive.

In a new study published in Carbon Research, scientists have developed a novel catalyst capable of eliminating ethyl acetate with remarkable efficiency at low temperatures. The team created a composite material by growing birnessite manganese dioxide (MnO₂) directly onto the surface of carbon nanotubes (CNTs). This approach creates a powerful and stable catalyst for breaking down harmful VOCs into harmless carbon dioxide and water.

Water pollution from industrial and agricultural activities poses a significant threat to human health and aquatic ecosystems worldwide. While various remediation techniques exist, many are expensive and complex, limiting their widespread use. A new comprehensive review published in Carbon Research explores a promising and sustainable solution: turning abundant agricultural waste into highly effective, low-cost adsorbents for cleaning contaminated water.

Raw agricultural wastes like straw, husks, and cobs naturally contain components that can bind to pollutants. However, their inherent structure often limits their capacity, making them inefficient in their natural state. This review synthesizes years of research on modifying these materials to dramatically enhance their ability to capture a wide range of contaminants, including heavy metals, dyes, pesticides, and antibiotics. By altering the physical and chemical properties of these wastes, scientists can create powerful, eco-friendly filters.

As atmospheric carbon dioxide levels continue to rise, accurately measuring the carbon stored in the world's forests has become more critical than ever. Forests are vital carbon sinks, but traditional measurement methods are often slow, labor-intensive, and prone to error. A new perspective published in Carbon Research highlights a powerful, modern approach: combining drone technology with machine learning to rapidly and precisely estimate forest carbon storage, offering a transformative tool in the fight against climate change.

A new study published in Carbon Research reveals the complex relationship between Turkey's economic development and its carbon footprint. Analyzing three decades of data from 1990 to 2020, researchers found that while economic growth, urbanization, industrialization, and tourism have significantly increased CO₂ emissions, the country's renewable energy sector, agricultural productivity, and forests offer a powerful counterbalance. The findings provide a quantitative basis for policies aimed at achieving environmental sustainability.A new study published in Carbon Research reveals the complex relationship between Turkey's economic development and its carbon footprint.
