Predictions for NO using the thermal mechanism are far too low indicating that prompt mechanism chemistry is needed for adequate predictions.
To realize a solar-driven water splitting device based on earth-abundant materials, new chemistry is needed, including materials for light harvesting and electrocatalysts for fuel production.
The current question, discussed in the present paper, is whether analogue macrocyclic bisphosphonate ligands can directly be converted from 68Ga complexes to 177Lu analogues, i.e., retaining organ uptake and pharmacology profiles known from Ga III) structures, or whether an alternative ligand chemistry is needed to match the coordination features of Lu III).
However, most cannabis strains don't produce the other cannabinoids in sufficient amounts, so a little chemistry is needed to either tease out these less-prominent compounds or convert them from other cannabinoid precursors in bulk.
No protection group chemistry is needed and the F-click cycloaddition step provides the final radiotracer.
Considerable knowledge of farming operations, exposure assessment, toxicokinetics, and analytical chemistry is needed for successful design, implementation, and interpretation of farmworker biomonitoring studies.
A multidisciplinary reading from the archaeology, the geology and the chemistry was needed to interpret the corpus of information.
Strong policy actions, as well as more research, development and innovation in green chemistry are needed for the substitution of POPs, EDC and other toxic substances in plastics as well as for the development of more benign alternatives to persistent polymers in the marine environment.
Chemistry was needed but also someone with great acting chops.
Restrained optimization, where the amino acid types can only change within small groups ("flavors") gives only a partial improvement, showing that significant changes in the sidechain physical chemistry are needed before the HMM sequences can pack.
