Nano‐Raman Spectroscopy of Tellurium Nanowires

Journal of Raman Spectroscopy, EarlyView.
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.
