This week we bring you application notes by Agilent Technologies, LECO, Shimadzu and Waters Corporation!

CEITEC scientists have experimentally shown for the first time that even weak halogen bonds between molecules share electrons, revealing a partly covalent nature.

Mineralogist Jakub Plášil uncovers complex crystal structures and discovers new minerals. His research deepens understanding of uranium in nature and earned him a major EMU award.

11 webinars: battery materials, diffraction, FT-IR gas analysis, flow cytometry, mineralogy, NMR, protein analysis, Raman, sorption analysis, tablet testing, tracer development, 21 CFR Part 11, XRD, XRM

This work introduces residue-based TGA to quantify carboxylate modifications in hyaluronic acid. The method is label-free, functional-group independent, and applicable to diverse polymers.

This study presents a multimethod strategy to quantify citrate ligands on iron oxide nanoparticles using TGA, CHN, qNMR, and RP-HPLC, showing how selective methods improve accuracy and prevent overestimation.
