Luminescent InP Quantum Dots with Tunable Emission by Post-Synthetic Modification with Lewis Acids.
The primary mechanism of PL turn-on is identified as surface passivation of phosphorus dangling bonds, affording PL QYs up to 49% without the growth of a type I shell or the addition of HF. Expand
Stabilizing unstable species through single-site isolation: a catalytically active TaV trialkyl in a porous organic polymer
A catechol-functionalized porous organic polymer (POP) has been successfully metallated with a TaV trialkyl and remains thermally and structurally robust. The resulting POP-supported (catecholato)TaVExpand
Assessing Regulatory Impact Analyses: The Failure of Agencies to Comply with Executive Order 12,866
I. INTRODUCTION Although regulations often have no direct fiscal impact, they pose real costs to consumers as well as businesses. Regulations aimed at protecting health, safety, and the environmentExpand
Assessing the Quality of Regulatory Impact Analyses
This study provides the most comprehensive evaluation of the quality of recent economic analyses that agencies conduct before finalizing major regulations. We construct a new dataset that includesExpand
Large ground-state entropy changes for hydrogen atom transfer reactions of iron complexes.
The discovery that DeltaS degrees HAT can deviate significantly from zero has important implications on the study of HAT and proton-coupled electron-transfer (PCET) reactions, and results indicate that free energies, rather than enthalpies, should be used to estimate the driving force for HAT when transition-metal centers are involved.

Standard Reduction Potentials for Oxygen and Carbon Dioxide Couples in Acetonitrile and N,N-Dimethylformamide.
The first estimates of the standard reduction potential of the O2 + 4e(-) + 4H(+) ⇋ 2H2O couple in organic solvents are reported, and extensions to other reduction potentials are discussed. Expand
Trends in ground-state entropies for transition metal based hydrogen atom transfer reactions.
Reported herein are thermochemical studies of hydrogen atom transfer (HAT) reactions involving transition metal H-atom donors M(II)LH and oxyl radicals. [Fe(II)(H(2)bip)(3)](2+),Expand
Nitroxyl radical plus hydroxylamine pseudo self-exchange reactions: tunneling in hydrogen atom transfer.
Calculations reveal why the phenyl groups make the last of these reactions several orders of magnitude faster than the first two, and suggest why tunneling appears to be more important in the self-exchange reactions of dialkylhydroxylamines than of arylhydxylamines. Expand
Models for Proton-coupled Electron Transfer in Photosystem II
The coupling of proton and electron transfers is a key part of the chemistry of photosynthesis. The oxidative side of photosystem II (PS II) in particular seems to involve a number of proton-coupledExpand
Synthesis, structure, and properties of a T-shaped 14-electron stiboranyl-gold complex.
A cyclic stiboranyl-gold complex supported by two 1,8-naphthalenediyl linkers has been synthesized and structurally characterized and surprisingly, the trivalent gold atom of this complex is involved in an aurophilic interaction, a phenomenon typically only observed for monovalent gold complexes.
