CDCl3 is the most frequently used solvent for the NMR investigation of organic compounds. Busy chemistry labs need to investigate hundreds of compounds daily. While 1H NMR investigation takes a couple of minutes, recording 13C NMR spectra necessitate

Investigating the metabolic profiles of solid sample materials with solution nuclear magnetic resonance (NMR) spectroscopy requires the extraction of these metabolites. This is commonly done by using two immiscible solvents such as water and chlorofo

In Japan, chloroethylene is a regulated substance under the soil contamination countermeasures act since 2017, due to the presence of chloroethylene in soil leachate and groundwater. As a consequence, chloroethylene concentrations must be accurately

The ability to perform air-free chemistry and catalytic reactions on an NMR tube scale are valuable skills in chemistry and not often included in undergraduate chemistry curriculum. This laboratory experiment provides students experience in synthesiz

Starting from simple metal precursors (AgNO3 and InCl3), ligands (oleylamine (OLA) and 1-dodecanethiol (DDT)) and popular sulfur precursor S/OLA, we have developed a new method for the preparation of colloidal Ag2S nanocrystals and highly luminescent

The measurement of d.c. ionic conductivity in samples that are not liquids or monolithic solids generally presents a problem. Here we show how the d.c. ionic conductivity determined for a powdered glass can reproduce the conductivity of the monolithi

Self-diffusion of ions in the protic ionic liquid ethylammonium nitrate (EAN) was studied by 1H NMR pulsed field gradient techniques between 294 and 393 K in the presence of a PTFE insert in a 5-mm NMR tube. At all temperatures, the bulk diffusion of
