Measurement of geologic nitrogen using mass spectrometry, colorimetry, and a newly adapted fluorometry technique [PDF]

open access: yesSolid Earth, 2017
Long viewed as a mostly noble, atmospheric species, recent work demonstrates that nitrogen in fact cycles throughout the Earth system, including the atmosphere, biosphere, oceans, and solid Earth.

Robustness of high‐throughput prediction of leaf ecophysiological traits using near infrared spectroscopy and poro‐fluorometry

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water scarcity is a major threat to crop production and quality. Improving drought tolerance through variety selection requires a deeper understanding of plant ecophysiological responses, but large‐scale phenotyping remains a bottleneck. This study assessed the potential of high‐throughput tools (spectroscopy and poro‐fluorometry) to predict ...

Design, Synthesis and Biophysical Characterisation of CPP-PNA Conjugates for Targeting Oncogenic microRNA-221. [PDF]

open access: yesJ Pept Sci
Cell‐penetrating peptide‐peptide nucleic acid (CPP‐PNA) conjugates that target the oncogenic microRNA‐221‐5p were synthesised using Cu(I)‐catalysed azide‐alkyne cycloaddition (CuAAC) and disulfide‐mediated conjugation strategies. These constructs form highly stable, sequence‐selective PNA/RNA heteroduplexes and demonstrate preliminary antiproliferative
