Dual‐State Photophysical Modulation via Bifurcated Hydrogen Bonding in a U‐Shaped Dipyridophenazine‐Cored Donor‐π‐Acceptor‐π‐Donor Fluorophore

Chemistry – A European Journal, EarlyView.
A donor–π–acceptor–π–donor (D–π–A–π–D) fluorophore bearing a U‐shaped dipyridophenazine core forms bifurcated hydrogen bonds with neutral donors such as sulfonamides or water. This interaction modulates both ground and excited states, enabling red‐shifted emission and enhanced photoluminescence in solution and solid state.

Dynamic phenomena in superconducting oxides by ESR [PDF]

, 1994
Dynamic electron spin resonance (ESR) measurements compare the paramagnetic and antiferromagnetic (AF) properties of superconducting oxides in the range 4 K to room temperature, at 8 MHz and 9.36 GHz. Two are derivatives of YBa2Cu30 7: 1: Nd(Nd0.05Ba0.95

Synthesis and Investigation of Bonding Scenario in a Bis(silaselenone)

European Journal of Inorganic Chemistry, EarlyView.
Silaselenones, the compounds containing Si=Se bond, are rarely reported in the literature. Silaselenones are the class of compounds that possess Si=Se bond. Herein, we report a bis(silaselenone) and we investigate nature of bonding between Si–Si atoms and Si—Amidinate moieties by employing Natural bond orbital (NBO), Quantum theory of atoms in ...

Gallein, a Gβγ subunit signalling inhibitor, inhibits metastatic spread of tumour cells expressing OR51E2 and exposed to its odorant ligand

BMC Research Notes, 2017
Objective We previously reported that the olfactory receptor OR51E2, overexpressed in LNCaP prostate cancer cells, promotes cell invasiveness upon stimulation of its agonist β-ionone, and this phenomenon increases metastatic spread.

XPS studies of nitrogen doping niobium used for accelerator applications

, 2018
Nitrogen doping study on niobium (Nb) samples used for the fabrication of superconducting radio frequency (SRF) cavities was carried out. The samples' surface treatment was attempted to replicate that of the Nb SRF cavities, which includes heavy ...

Phosphoramidate and Silyl Amine Mediated Synthesis of Isocyanide Cyclopentadienone Iron Complexes

Helvetica Chimica Acta, EarlyView.
Carbonyl ligands in cyclopentadienone iron complexes are replaced by isocyanide ligands without using free, malodorous isocyanides. The reaction takes place via an Aza‐Wittig‐type reaction starting from primary amines, employing either phosphoramidates or silyl amines as intermediate reagents.

Combination therapy with normobaric oxygen (NBO) plus thrombolysis in experimental ischemic stroke

BMC Neuroscience, 2009
Background The widespread use of tissue plasminogen activator (tPA), the only FDA-approved acute stroke treatment, remains limited by its narrow therapeutic time window and related risks of brain hemorrhage.
