Researchers have created a high-performance infrared detector that operates at room temperature without requiring external power or cooling. By growing high-quality lead sulfide films and using an asymmetric electrode design, the device achieves fast response and clear imaging, paving the way for affordable, compact infrared cameras in smartphones, automobiles, and security systems.

Ghost forests serve as powerful, visible warnings of climate change. Encroaching ocean waters are poisoning salt-intolerant trees, leaving behind eerie skeletal remains. Researchers from the University of Delaware are wading through these surreal landscapes along the mid-Atlantic coastline to determine the environmental impact of this climate-driven phenomenon. The researchers will present their results at ACS Spring 2026.

Researchers from The University of Osaka have proposed a compact LED design that directly emits circularly polarized light using a nanoscale GaN metasurface integrated onto the device. This design removes the need for bulky optical components traditionally used to create polarized light and could help enable smaller optical systems for applications such as 3D displays, augmented reality, and photonic technologies.

Rivers do not just move water; they act as nature's hard drives, saving a permanent record of what happens on the surface. When toxic chemicals settle into the mud at the riverbed, they create a chronological diary of human activity. Recently, a detailed investigation published in Carbon Research has opened up one of these geological diaries in Mongolia’s Orkhon River Basin, revealing exactly how economic booms and traffic jams translate into chemical fallout.

The detective work was spearheaded by corresponding author Jing Chen from Beijing Normal University. Drawing on the analytical power of the State Key Joint Laboratory of Environment Simulation and Pollution Control and the Center for Atmospheric Environmental Studies, Chen's team extracted sediment cores to trace the history of polycyclic aromatic hydrocarbons (PAHs)—a notoriously stubborn class of toxic pollutants created by burning fuel and organic matter.

A new strategy for the efficient conversion of hemicellulose to furfural through a microwave-coupled multi-stage tandem process was proposed by the research team led by Academician Jiang Jianchun from the Institute of Chemical Industry of Forest Products, Chinese Academy of Forestry.

A flexible film that can passively repel ice and actively melt frost using only weak sunlight could replace energy-heavy heating grids in aviation and renewable energy.

Planting trees is widely championed as a straightforward, nature-based fix for global warming. The logic seems foolproof: expanding forests should pull more carbon dioxide from the air and pack it safely into the earth. However, a sweeping five-decade analysis of land transformation in Kerala, India, suggests the reality beneath the surface is full of unexpected trade-offs.

Published in the journal Carbon Research, the study was spearheaded by corresponding author V. K. Dadhwal at the School of Natural Sciences & Engineering, National Institute of Advanced Studies in Bengaluru. His team utilized advanced machine learning to map how half a century of plantation expansion actually impacted the dirt itself. Their findings challenge a popular assumption, proving that massive afforestation campaigns do not automatically equal a massive boost in soil organic carbon (SOC).

To accurately track the landscape from 1972 to 2020, the research team moved beyond traditional area-based counting. They fed a Random Forest predictive model with detailed historical land use maps, legacy soil measurements, local climate data, and topographic variables. This high-resolution approach allowed them to pinpoint specific geographical hotspots where carbon was either successfully sequestered or silently lost.

Phosphorus is an absolute necessity for growing crops, yet a massive portion of it remains locked away in the dirt, completely inaccessible to plant roots. Keeping enough "labile"—or readily available—phosphorus in agricultural fields is a constant headache for the farming industry. Now, a fresh look at the soil microbiome reveals that the key to freeing up this trapped nutrient relies heavily on the type of carbon we add to the earth, whether that is treated animal waste or, surprisingly, synthetic plastic pollution.

Featured in the journal Carbon Research, this detailed ecological assessment maps the underground mechanisms that drive nutrient cycling. The research was jointly led by corresponding authors Huifang Xie and Bingyu Wang from the Jiangsu Key Laboratory of Chemical Pollution Control and Resources Reuse, housed within the School of Environmental and Biological Engineering at Nanjing University of Science and Technology.

The team wanted to understand how two very different types of human-introduced carbon affect the soil's ability to feed plants. They compared manure-derived hydrochar (HC)—a common, nutrient-rich soil amendment—against TPU microplastics (MPs), an increasingly ubiquitous environmental contaminant.
