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.

One of the major topics in the field of zeolite synthesis is to control zeolite morphology with increased external surface areas, aiming to minimize mass transfer limitations and thus maximize access to micropores. Currently, it has been successfully synthesized zeolites with various morphologies. Herein, researchers briefly reviewed recent progress for morphological control of zeolite crystals from organic templates including typically industrial zeolites.

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.

The Challenge of Sandy Soils

With drylands covering over 40% of the Earth's land area, improving the agricultural potential of sandy soils is a critical global challenge. These soils, common in arid and semi-arid regions, are notoriously poor at retaining water, making it difficult for crops to survive and thrive, especially with increasing drought periods due to climate change. For decades, scientists have explored organic amendments like compost and biochar—a charcoal-like substance made from pyrolyzed biomass—to improve soil quality. While promising, the exact recipe for success and the best methods for testing their effects have remained unclear.

Heavy metal pollution from industrial and agricultural activities poses a significant threat to soil health, agricultural productivity, and ecosystem stability. These toxic metals, such as copper (Cu), arsenic (As), cadmium (Cd), and zinc (Zn), are nondegradable and can harm soil microorganisms that are essential for nutrient cycling and overall soil fertility. Finding effective and environmentally friendly methods to remediate contaminated land is a critical challenge for environmental scientists and policymakers.

In a significant advancement for electronics and materials science, researchers have developed a novel nanocomposite material with remarkably enhanced properties. By embedding crystalline reduced graphene oxide (rGO) into a specialized adhesive polymer matrix, a team of scientists has created a material with superior electrical conductivity, thermal stability, and an exceptional ability to absorb electromagnetic energy. This breakthrough, published in the journal Carbon Research, paves the way for more robust and efficient electronic components, particularly in demanding fields like aerospace and defense.

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.

When we think of charcoal or soot, we often picture a solid, inert substance. However, a significant portion of this "black carbon"—produced from wildfires, fossil fuel combustion, and biochar applications—dissolves in water, becoming what scientists call dissolved black carbon (DBC). This mobile and active component plays a crucial, yet often overlooked, role in the global carbon cycle. A new review published in Carbon Research provides a comprehensive overview of DBC, detailing its structure, its behavior in aquatic environments, and the advanced methods used to study it. The findings highlight DBC's importance in connecting carbon pools between land and sea and its significant impact on water chemistry and ecology.
