Elemental Composition Analysis of Sheep Tears Using Particle‐Induced X‐Ray Emission

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To identify the elemental composition of ovine tears using particle‐induced X‐ray emission (PIXE). Animals Studied Ten physically healthy female sheep. Procedures Tear samples were collected using Schirmer tear test strips. Tear samples were collected once daily over five consecutive days to assess reproducibility. Elemental analysis

Wavelength Dependence of fs Laser Ablation Ionisation Mass Spectrometry: a Dedicated Study on NIST SRM 664

Rapid Communications in Mass Spectrometry, Volume 40, Issue 5, 15 March 2026.
ABSTRACT Rationale Laser ablation mass spectrometry provides fast and direct chemical information of solids with high spatial resolution without the need for complex sample preparation. It has been shown that reducing the laser pulse length below picoseconds improves the quantification of chemical composition measurements of solids. This study compares

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...
