Life on Earth: UV and HCN

Date: Nov 1, 2017

Author: David Bradley

UV-Vis spectroscopy has revealed that the experimental conditions for the polymerization of aqueous HCN (hydrogen cyanide) affect the kinetics of the reaction. Given the purported role of HCN in the prebiotic organic chemistry of our planet, such insights might ultimately have implications for our understanding of how life on earth began.

Environmental, healthcare sensor: Thiourea testing

Date: Oct 1, 2017

Author: David Bradley

Co-doped manganese oxide nanoparticles (CMOs) can be made with a facile hydrothermal method and used in an emzyme-free, yet highly sensitive thiourea sensor. A whole raft of analytical techniques, including ultraviolet-visible (UV-Vis) spectroscopy, was used to characterize the particles.

Journal Highlight: Detection of copper bisguanidine NO adducts by UV-vis spectroscopy and a SuperFocus mixer

Date: Sep 11, 2017

Author: spectroscopyNOW

The reaction of Cu(I) bisguanidine complexes with nitric oxide and the formation of intermediate species were monitored via UV-vis spectroscopy at low temperature and the limits of the SuperFocus mixer for this reaction were explored.
