Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

Small, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Low‐Frequency Noise and Stability in Electrolyte‐Gated Nanoscale Silicon Field‐Effect Transistor Sensors

Small Methods, EarlyView.
Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...

Exploring Local Structure in Iron Oxide Nanoparticles During Chemical Vapor Synthesis by in Situ and Operando X‐Ray Absorption Spectroscopy

Small Methods, EarlyView.
In situ and operando XAS is used to probe nanoparticle formation during chemical vapor synthesis, where particles form in the gas phase under high‐temperature conditions. XANES reveals dynamic changes to the oxidation states while EXAFS indicates local structural variations under in situ probing conditions.

The Chemical Effects of Nitrogenous Substances in Two Different Grades of PVDF Used in Offshore Applications

Journal of Vinyl and Additive Technology, EarlyView.
Proposed reaction schematic. ABSTRACT In this work, two different grades of poly(vinylidene fluoride) (PVDF) commonly used in offshore applications, one with 3% of dibutyl sebacate (DBS) plasticizer and the other a copolymer containing chlorotrifluoroethylene (CTFE), were subjected to an aging process in contact with a fluid containing hydrocarbons ...
