Molecular ion trap-depletion spectroscopy of BaCl$^+$

, 2011
We demonstrate a simple technique for molecular ion spectroscopy. BaCl$^+$ molecular ions are trapped in a linear Paul trap in the presence of a room-temperature He buffer gas and photodissociated by driving an electronic transition from the ground X$^1 ...

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

Advanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

Advanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

Photodissociation and the Morphology of HI in Galaxies

, 2004
Young massive stars produce Far-UV photons which dissociate the molecular gas on the surfaces of their parent molecular clouds. Of the many dissociation products which result from this ``back-reaction'', atomic hydrogen \HI is one of the easiest to ...
