High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.

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.

Phototherapies mediated by metallic nanoparticles and near‐infrared radiation in skin cancer: A systematic review

Photochemistry and Photobiology, EarlyView.
Recent studies demonstrate that near‐infrared (NIR—750–980 nm)‐mediated photodynamic (PDT) and photothermal (PTT) therapies, combined with metallic nanoparticles (MNPs), show promising results against skin cancer, particularly melanoma, in both in vitro and in vivo models.

Electrochemical Determination of Amyloid Beta Biomarker Ratios in Serum Using a Pyr‐NHS‐Functionalized 3D Graphene Foam Electrode

Analysis &Sensing, Volume 6, Issue 6, November 2026.
An electrochemical biosensing platform based on 1‐pyrenebutyric acid N‐hydroxysuccinimide ester (Pyr‐NHS) functionalized 3D graphene foam is developed for resolving amyloid beta (Aβ42 and Aβ40) biomarker ratios in human serum with femtomolar limits of detection, offering a foundational step forward in prospective point‐of‐care screening tools.
