Web11 hours ago · Nanoscale chirality is an actively growing research field spurred by the giant chiroptical activity, enantioselective biological activity, and asymmetric catalytic activity of chiral nanostructures. Compared to chiral molecules, the handedness of chiral nano- and microstructures can be directly established via electron microscopy, which can be utilized … WebGrinding solid materials in a ball mill speeds up sublimation and can be used to separate chiral molecules in a simple way. The finding by scientists in Germany who developed a way to monitor the process in real time using NMR spectroscopy, could open up new possibilities in pharmaceutical research and medicinal chemistry.
