The reaction of an aqueous solution of Na3SbS4·9H2O with a Co(II) salt dissolved in acetonitrile in the presence of tris(2‐aminoethyl)amine afforded crystallization of [Co2(S2)2(tren)2]3[SbS4]2 · 21.5 H2O which contains in situ formed S22‐ anions and Co(III) cations formed by oxididation of Co(II).

The pincer complex (2‐Tol)PtII(NCN) (NCN = [2,6‐bis{(dimethylamino)methyl}phenyl‐N,C,N]‐) reacts with diiodine via electrophilic cleavage to give PtII(NCN)I and 2‐tolyl iodide, together with oxidative addition to give cis‐(2‐Tol)PtIV(NCN)I2 (van Koten et al. 1990).

Phosphorus‐substituted tetrylenes and ditetrelenes remain something of a rarity. The reaction between SnCl2 and two equivalents of (Dep2P)Li at low temperature gave the bis(phosphanyl)stannylene {(Dep)2P}2Sn (4Sn), although this compound decomposes in solution at room temperature (Dep = 2,6‐Et2C6H3).

Polyoxotungstates‐stabilized gold nanoparticles: how to transfer from an aqueous suspension to CH3CN
The present study aimed to evaluate available methods for preparing suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions. POMs@AuNPs were successfully synthesized in CH3CN using three different approaches: (i) in situ generation of nanoparticles via chemical reduction of ...

Carbonyl iron complexes bearing cyclopentadienone/hydroxycyclopentadienyl ligands and N‐heterocyclic carbene as non‐innocent and ancillary ligands, are active as ammonia‐borane dehydrocoupling catalysts under photo‐activation conditions. Dehydrogenation occurs at room temperature and is complete (in NMR tube) after 2h with 10 mol% of cationic complex 2,

Transition‐Metal‐Free Carboxylation of Aryl Boronates in Supercritical CO2
Carboxylation using stable and abundant CO2 as a carbon source would be an attractive option in synthetic organic chemistry if the use of highly reactive organometals or toxic and expensive transition metals can be avoided. Herein we report a transition‐metal‐free direct carboxylation of aryl trialkoxyboronates in supercritical CO2 (scCO2), promoted by

Magnetic Resonance Acoustic Radiation Force Imaging (MR‐ARFI)
This review covers the theoretical background, pulse sequence considerations, practical implementations, and multitudes of applications of magnetic resonance acoustic radiation force imaging (MR‐ARFI) described to date. MR‐ARFI is an approach to encode tissue displacement caused by the acoustic radiation force of a focused ultrasound field into the ...

BDLUT: Blind image denoising with hardware‐optimized look‐up tables
BDLUT(‐D) is a novel blind denoising method combining optimized lookup tables (LUTs) with hardware‐centric design. While BDLUT describes the LUT‐based network architecture, BDLUT‐D represents BDLUT trained with a specialized noise degradation model. Designed for edge deployment, BDLUT(‐D) eliminates neural processing units (NPUs) and functions as a ...
