The H-band Emitting Region of the Luminous Blue Variable P Cygni: Spectrophotometry and Interferometry of the Wind

open access: yes, 2013
We present the first high angular resolution observations in the near-infrared H band (1.6 μm) of the luminous blue variable star P Cygni. We obtained six-telescope interferometric observations with the CHARA Array and the MIRC beam combiner.

Assessment of antimicrobial activity and methyl orange dye removal by Klebsiella pneumoniae-mediated silver nanoparticles

open access: yesGreen Processing and Synthesis
The synthesis of silver nanoparticles (AgNPs) using bacteria is more interesting because of their non-toxic, biocompatible, environmentally friendly, and cost-effectiveness. In the present research work, AgNPs were synthesized by Klebsiella pneumoniae in

Bioconversion and characterization of watermelon rind waste‐based microcrystalline cellulose: A green alternative to synthetic reinforcements

open access: yesPolymer International, EarlyView.
Microcrystalline cellulose (MCC) was extracted from watermelon rind using acid hydrolysis. MCC can be efficiently used as reinforcement in biofilms and biocomposites. Abstract The increasing accumulation of agricultural waste from watermelon (Citrullus lanatus) represents a substantial environmental concern, particularly in view of the extensive ...

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

open access: yesSmall, 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.

In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

open access: yesSmall, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

Temporal and geographical patterns of nitazene detections in drug samples and biospecimens in the United States, 2019–2024

open access: yesAddiction, EarlyView.
Abstract Background and aims Nitazenes are a novel subclass of synthetic opioids that have been increasingly implicated in the United States (US) overdose crisis. Despite their growing presence in the illicit drug supply, national trends have not been systematically evaluated.

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Photoelectrocatalytic Degradation of Tetracycline Using Covalent Organic Frameworks Under Neutral Conditions

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
A methoxy‐functionalized pyrene‐based covalent organic framework (Py‐OCH3‐COF) enables efficient photoelectrocatalytic (PEC) degradation of tetracycline (TC) under neutral conditions. PEC synergy promotes charge separation, reshapes reactive oxygen species, and generates singlet oxygen as the dominant species, leading to rapid and effective TC ...
