2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Isotope shift in the electron affinity of chlorine

, 1995
The specific mass shift in the electron affinity between ^{35}Cl and ^{37}Cl has been determined by tunable laser photodetachment spectroscopy to be -0.51(14) GHz. The isotope shift was observed as a difference in the onset of the photodetachment process

Recent Progress in the Development of Metal‐Based Radiosensitizations for Cancer Therapy: A Review

Rare Metals, EarlyView.
ABSTRACT Radiotherapy (RT) remains an indispensable means in cancer treatment; however, its therapeutic efficacy is often limited by tumor radioresistance and side effect of damage to healthy tissue. The advances in nanotechnology have propelled metal radiosensitizers to forefront of precision medicine.

Studies of the $^{1}$S$_{0}$--$^3$P$_0$ transition in atomic ytterbium for optical clocks and qubit arrays

, 2005
We report an observation of the weak $6^{1}$S$_{0}$-$6^3$P$_0$ transition in $^{171,173}$Yb as an important step to establish Yb as a primary candidate for future optical frequency standards, and to open up a new approach for qubits using the $^{1}$S$_{0}
