Fluorinated Hypercrosslinked Polymers with Exceptional Capacity for Perfluorooctanoic Acid Removal from Water

Small, EarlyView.
Fluorinated hypercrosslinked polymers (FHCPs) are reported as highly efficient sorbents for the rapid removal of perfluorooctanoic acid (PFOA) from water. The materials integrate strong fluorophilic interactions, extensive porosity, and excellent chemical stability, delivering fast adsorption kinetics, high uptake capacity, and selective PFOA removal ...

Laser‐Assisted In Situ Fabrication of rGO/Bi2O3 Nanocomposites for Heavy Metal Sensing

Small, EarlyView.
Rapid CO2 laser irradiation drives the in situ formation of Bi2O3 nanoplatelets within reduced graphene oxide, yielding flexible, reproducible electrodes with excellent stripping voltammetric performance toward trace heavy metals. ABSTRACT In this work, we introduce a laser‐assisted approach to synthesize reduced graphene oxide/bismuth oxide (III) (rGO/

Approaching Gold‐Standard Sensitivity in a Portable and Versatile Gold Nanoprisms Thermoplasmonic Platform for Lateral Flow Detection of Biomolecules

Small, EarlyView.
This study presents a plasmonic thermal lateral flow (ThermoLFA) biosensor for ultrasensitive, early detection of biomolecules. By combining plasmonic gold nanoprisms (AuNPrs) and near‐infrared (NIR) laser activation, it enhances signal output beyond conventional LFAs.

Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high
