Electrical properties of Bi-implanted amorphous chalcogenide films

, 2014
The impact of Bi implantation on the conductivity and the thermopower of amorphous chalcogenide films is investigated. Incorporation of Bi in Ge-Sb-Te and GeTe results in enhanced conductivity.

Photocatalysis with Chalcogen Bonds

In a recent prebiotically plausible synthesis of 2'-deoxyribose-2-thiouridine, UV irradiation and aqueous bisulfide were employed to conduct the photoreduction of 2',2-thioanhydrouridine, resulting in the formation of the non-canonical thiopyrimidine nucleoside.

Chalcogen‐Directed Dual‐Heterointerfaced Bi2Te3/BiSx in N‐Doped Carbon Nanofibers for Sodium Storage

Small, EarlyView.
Dual crystalline/amorphous heterointerfaces of Bi2Te3/BiSx encapsulated in N‐doped porous carbon nanofibers are engineered as an advanced anode for sodium‐ion batteries. The synergistic heterointerfaces and Te vacancies enable fast charge transport, buffer volume expansion, and ensure structural integrity. The anode delivers exceptional rate capability

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Backbone double‐mutant cycle analysis quantifies hydrogen‐bond energies in proteins

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Protein structure is stabilized by a variety of noncovalent interactions, but many remain incompletely understood. For example, several potentially ubiquitous interactions involving the protein backbone have been identified, but challenges in determining reliable experimental energies have prevented their integration into structural models. To
