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

Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

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 ...

Topical rosiglitazone is an effective anti-scarring agent in the cornea

, 2013
Corneal scarring remains a major cause of blindness world-wide, with limited treatment options, all of which have side-effects. Here, we tested the hypothesis that topical application of Rosiglitazone, a Thiazolidinedione and ligand of peroxisome ...

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

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.

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.

Pulsed Laser Micro Polishing: Surface Prediction Model

, 2011
This project is focused on developing physics-based models to predict the outcome of pulsed laser micro polishing (PL P). Perry et al. have modeled PL P as oscillations of capillary waves with damping resulting from the forces of surface tension and ...

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 ...
