, 1978 A review of lasers with potential photochemical applications in waste management indicates that dye lasers, as a class, can provide tunable laser output through the visible and near-uv regions of the spectrum of most interest to photochemistry.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology
Journal of Metamorphic Geology, EarlyView.ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

Plant, Cell &Environment, EarlyView.ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Long-pulse excimer lasers for materials processing and medical applications [PDF]
, 1986 Present day commercial excimer lasers with the exception of the Helionetics device are inherently short pulse ultraviolet sources. The pulses are short due to the inherent instability of the avalanche discharge with electronegative elements in the gas ...

Spectroscopic analysis of bacterial photoreactivation
Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Depth of DNA photodamage in human corneas exposed to 222 nm or 254 nm UV
Photochemistry and Photobiology, EarlyView.Representative confocal 3D image of a section of a human cornea showing nuclei in blue (Hoechst 33342) and green, which was assigned to cells exhibiting Alexa555 conjugated to anti‐CPD antibody. The depth of photodamage was measured in Z‐stacks of the human corneal epithelium after exposure of the anterior surface to 50 or 100 mJ/cm2 at 222 or 254 nm ...
