Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

Chemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...

X‐Ray Absorption Sensitivity at 5d$5d$ Edges of High‐Valent Light Actinides to Crystal‐Field Strength and Covalency Effects

Chemistry – A European Journal, EarlyView.
Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres

Chemistry – A European Journal, EarlyView.
We expand the scope of Pd12L24 nanospheres equipped with porphyrins. Focusing on the porphyrin metallation state, synthetic strategies for porphyrin building block (BB)compounds are developed. The compounds are evaluated against nanosphere self‐assembly conditions.

The life and work of Ernest Sydney Keeping

Canadian Journal of Statistics, EarlyView.
Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...
