Impact of Beam Profile on Raman Spectroscopy Measurements
Journal of Raman Spectroscopy, Volume 57, Issue 1, Page 181-191, January 2026.Characterisation and optimisation of the laser beam profile in Raman spectroscopy is critical to ensure accuracy and reproducibility of measurements. The laser beam size and profile have a significant effect on the axial resolution, energy distribution on the sample, focal spot size and excitation volume.

Fenton‐like Reactivity on Fe3O4 Nanozymes Driven by Charge Transfer and Interfacial Water
Small, Volume 22, Issue 3, 13 January 2026.In magnetite nanozymes, subsurface Fe2⁺ donates electrons to H2O2, forming fleeting Fe(IV)═O and •OH species. The process couples charge flow, water‐mediated reactivity, and nanoparticle oxidation in a dynamic Fenton‐like cycle. Abstract Magnetite (Fe3O4) nanoparticles, widely recognized as inorganic nanozymes due to their enzyme‐like catalytic ...
