Enhanced Xylene Sensing Performance of Fe‐Doped NiO Nanosheet Arrays via In Situ Growth

Advanced Materials Interfaces, EarlyView.
Xylene is a hazardous volatile organic compound (VOC) widely present in industrial environments, and achieving sensitive and stable detection of xylene remains a significant challenge for gas sensors. Here, a one‐step hydrothermal route was employed to in situ grow p‐type Fe‐doped NiO nanosheet arrays on ceramic tubes for xylene detection.

Volatile Organic Compounds in the Po Basin. Part B: Biogenic VOCs [PDF]

Journal of Atmospheric Chemistry, 2005
Measurements of volatile organic compounds (VOCs) were performed in the Po Basin, northern Italy in early summer 1998, summer 2002, and autumn 2003. During the three campaigns, trace gases and meteorological parameters were measured at a semi-rural station, around 35 km north of the city center of Milan.

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

Advanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

A new system to study directional volatile-mediated interactions reveals the ability of fungi to specifically react to other fungal volatiles

Frontiers in Ecology and Evolution, 2023
Microbes communicate with each other using a wide array of chemical compounds, including volatile organic compounds (VOCs). Usually, such volatile-mediated interactions are studied by growing two different microbes in a shared, confined environment and ...

Field observations of volatile organic compound (VOC) exchange in red oaks [PDF]

Atmospheric Chemistry and Physics, 2017
Abstract. Volatile organic compounds (VOCs) emitted by forests strongly affect the chemical composition of the atmosphere. While the emission of isoprenoids has been largely characterized, forests also exchange many oxygenated VOCs (oVOCs), including methanol, acetone, methyl ethyl ketone (MEK), and acetaldehyde, which are less well understood.

Machine Learning for Green Solvents: Assessment, Selection and Substitution

Advanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...
