TL;DR: Of noble descent: a fully noble-metal-free system for the photocatalytic reduction of water at room temperature has been developed that consists of Cu(I) complexes as photosensitizers and [Fe(3)(CO)(12)] as the water-reduction catalyst.

Visible-to-NIR-Light Activated Release: From Small Molecules to Nanomaterials.
TL;DR: This review comprehensively covers organic and transition metal-containing photoactivatable compounds (complexes) that absorb in the visible- and NIR-range to release various leaving groups and gasotransmitters (carbon monoxide, nitric oxide, and hydrogen sulfide).
Journal ArticleDOI
New Ru(II) complexes for dual photoreactivity: ligand exchange and (1)O2 generation.
TL;DR: Dual activity via ligand dissociation and (1)O2 production can be achieved by careful selection of the ligand set to tune the excited-state dynamics, which can be applied to the use of Ru(II)-polypyridyl compounds in a variety of applications.

Photoactivated in Vitro Anticancer Activity of Rhenium(I) Tricarbonyl Complexes Bearing Water-Soluble Phosphines
Sierra C. Marker,Samantha N. MacMillan,Warren R. Zipfel,Zhi Li,Peter C. Ford,Justin J. Wilson +5 more
TL;DR: Data indicate that the phototoxic response may result from the release of both CO and the rhenium-containing photoproduct, as well as the production of 1O2.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.

Rapid colorimetric assay for cellular growth and survival: Application to proliferation and cytotoxicity assays
TL;DR: A tetrazolium salt has been used to develop a quantitative colorimetric assay for mammalian cell survival and proliferation and is used to measure proliferative lymphokines, mitogen stimulations and complement-mediated lysis.

Ab initio effective core potentials for molecular calculations. Potentials for the transition metal atoms Sc to Hg
P. Jeffrey Hay,Willard R. Wadt +1 more
TL;DR: In this article, the Coulomb, exchange, and core-orthogonality effects of the chemically inert core electron in the transition metal atoms Sc to Hg have been replaced by the ab initio effective core potentials (ECP).
Journal ArticleDOI
Optimization of parameters for semiempirical methods I. Method
TL;DR: In this paper, a new method for obtaining optimized parameters for semi-empirical methods has been developed and applied to the modified neglect of diatomic overlap (MNDO) method.
