Halogen‐Mediated Polymer‐Free Recovery of Pristine MoS2 Monolayers From Gold‐Assisted Exfoliation

Small Methods, EarlyView.
Schematic procedure for halogen‐mediated polymer‐free recovery of pristine MoS2 monolayers from gold‐assisted exfoliation. ABSTRACT Metal‐assisted mechanical exfoliation has recently emerged as a powerful strategy for producing large‐area monolayers of two‐dimensional (2D) transition‐metal dichalcogenides (TMDs) with near‐intrinsic crystalline quality.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐

Alkali Chalcogenido Dialuminates A 6[Al2 Q 6] (A = K, Rb, Cs; Q = S, Se, Te)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Seven new alkali chalcogenido aluminates A6[Al2Q6] (A = K‐Cs, Q = S‐Te) complement the family of simple metallates(III) A6[M2Q6] (M = Al‐In, FeIII) with dinuclear anions of two edge sharing [AlQ4] tetrahedra. Despite the similar anions, straightforward bonding situation and physical properties, these metallates crystallize in seven different structure ...

Isolation and Structural Elucidation of the Pnictogen Polysulfate Compounds As2[S2O7]2[S3O10] and [SeCl3][Pn(S2O7)2] (Pn = Sb, Bi)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The isolation and solid‐state structures of the two disulfate‐containing pnictogenates [SeCl3][Pn(S2O7)2] (Pn = Sb, Bi), as well as the mixed‐anionic As2[S2O7]2[S3O10] are presented. The former two consist of complex ∞1{[Pn(S2O7)1/1t(S2O7)2/2e]‐}$$ {\infty }^{1}\left\{{\left[\mathrm{Pn}{\left({\mathrm{S}}_{2}{\mathrm{O}}_{7}\right)}_{1/1}^{\mathrm{t}}{\

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.
