Quantitative structure-property relationships (QSPRs) on direct photolysis of PCDDs
, 2001 By the use of partial least squares (PLS) method and 27 quantum chemical descriptors computed by PM3 Hamiltonian, a statistically significant QSPR were obtained for direct photolysis quantum yields (Y) of selected Polychlorinated dibenzo-p-dioxins (PCDDs)

THE FLASH PHOTOLYSIS OF DIACETYLENE
, 1957 A brief description is given of a "microsecond" flash photolysis apparatus in which a 40 µf. condenser charged to 8000 v. is discharged through a photolysis flash tube in ~20 microseconds.

Phosphanyl Radicals From Bismuth‐Mediated Reactions and Sterically Encumbered Diphosphanes
Chemistry – A European Journal, EarlyView.Reactions of LiPR2 with BiCl3 selectively give diphosphanes R2P–PR2 in high yields, presumably via Bi─P homolysis. This includes challenging cases with bulky substituents R. Sterically encumbered diphosphanes release persistent phosphanyl radicals [PR2]• in thermally initiated equilibrium reactions.

Designing a Triplet 2‐Formylphenylnitrene With Fast Tunneling Reactivity
Chemistry – A European Journal, EarlyView.A 3‐CF3 substituent accelerates tunneling in triplet 2‐formylphenylnitrene, making its reactivity in cryogenic matrices too fast for conventional IR spectroscopic detection. Bringing this chemistry to low‐temperature solutions allows suppression of intrinsic nitrene dimerization through faster cyclization, which even outcompetes the 1,4‐H shift ...

The flash photolysis of ethenetetracarbonitrile
, 1975 The flash photolysis of ethenetetracarbonitrile gives rise to two short-lived diffuse absorption bands at 299.0 and 321.2 nm which are tentatively attributed to the dicyanocarbene radical.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Photolysis of Di-t-butylnitroxide
, 1982 Di-t-butylnitroxide (1) on photolysis in methylcyclohexane gives in addition to t-butoxy(di-t-buty1)-amine (7) and photolabile 2-methyl-2-nitrosopropane (2) a low yield of a white crystalline solid identified as a mixture of di-t-butylhydroxylammonium ...

EcoEnergy, EarlyView.An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.
