Pyranopterin conformation defines the function of molybdenum and tungsten enzymes
TL;DR: It is demonstrated that pyranopterin conformation is correlated with the protein folds defining the three major mononuclear molybdenum and tungsten enzyme families, and that binding-site micro-tuning controls pyrAnopterin oxidation state.

Jian Gao,Benjamin W. Stein,Alan K. Thomas,Jose A. Garcia,Jing Yang,Martin L. Kirk,John K. Grey +6 more
TL;DR: In this article, the charge transfer doping efficiencies of π-stacked poly(3-hexylthiophene) (P3HT) aggregate nanofibers are studied using spectroscopic and electron microscopy probes.
Electronic and Exchange Coupling in a Cross-Conjugated D–B–A Biradical: Mechanistic Implications for Quantum Interference Effects
Martin L. Kirk,David A. Shultz,Daniel E. Stasiw,Diana Habel-Rodriguez,Benjamin W. Stein,Paul D. Boyle +5 more
TL;DR: The results reveal important excited-state contributions to the ground-state singlet-triplet splitting in this cross-conjugated D-B-A biradical that contribute to the understanding of electronic coupling in cross- Conjugated molecules and specifically to quantum interference effects.

TL;DR: X-ray absorption near-edge spectroscopy, ground-state density functional theory (DFT), and transition dipole moment calculations are used to investigate the possibility that Ln(C5H4SiMe3)31- (Ln = Pr, Nd, Sm, Gd, Tb, Dy, Y, Ho, Er, Tm, Yb and Lu) compounds represented molecular LnII complexes.
The coordination chemistry of CmIII, AmIII, and AcIII in nitrate solutions: an actinide L3-edge EXAFS study
Maryline G. Ferrier,Benjamin W. Stein,Sharon E. Bone,Samantha K. Cary,Alexander S. Ditter,Alexander S. Ditter,Stosh A. Kozimor,Juan S. Lezama Pacheco,Veronika Mocko,Gerald T. Seidler +9 more
TL;DR: CmIII, AmIII, and AcIII have been characterized by solution L3-edge X-ray absorption spectroscopy as a function of nitric acid concentration and this enabled the first experimental determination of Cm and Ac nitrate distances.
