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

Photochemistry 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.

Photochemistry of CryB from Rhodobacter sphaeroides

Photochemistry and Photobiology, EarlyView.
Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.

Insights Into the Mechanistic Assessment of Plasmon‐Induced Aqueous Degradation of Pharmaceuticals by TiO2/Ag Nano‐Composite

Water and Environment Journal, EarlyView.
ABSTRACT Pharmaceutical contaminants in potable water sources are ubiquitous and have resulted in lowered water quality. Thus, two common broad‐spectrum pharmaceuticals (tetracycline‐TC and ciprofloxacin‐CPF) were comparatively photo‐degraded using Ag‐doped TiO2 photocatalyst species containing Ag nanoparticles at 2.5, 5, and 7.5 wt%.

Sustainability Assessment of Alternative Methods for Destruction of Per‐ and Polyfluoroalkyl Substances (PFAS) in Water

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the
