CO molecular tilting detected by red-shifted TERS
Chinese Academy of Sciences

The interaction between a probing tip and an adsorbed molecule can significantly impact the molecular chemical structure. The tip-induced bond weakening, tilting, and hopping processes of a single molecule were investigated by sub-nanometre resolved tip-enhanced Raman spectroscopy (TERS). The C−O stretching mode is always redshifted as the tip approaches, revealing the weakening of the C−O bond. Further analyses of the vibrational Stark effect and TERS imaging suggest a delicate tilting of the adsorbed CO molecule.

Scientists Identify an Alternative System for Producing the Medical Isotope Scandium-44
Department of Energy, Office of Science

Scandium-44 is a promising medical isotope for positron emission tomography (PET) imaging for identifying cancer, heart disease, and other conditions. Scandium-44 can be produced through the radioactive decay of titanium-44, but the challenge is to reliably separate scandium-44 from titanium-44 at hospitals. A new approach produces an isotope generator that is portable, uses facilities routinely available at hospitals, and works efficiently and reliably. This will enable medical staff to more easily use scandium-44 for PET scans and other applications.
