Electronic correlations in organometallic complexes

, 2011
We investigate an effective model for organometallic complexes (with potential uses in optoelectronic devices) via both exact diagonalisation and the configuration interaction singles (CIS) approximation.

Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

Angewandte Chemie, EarlyView.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

Hexavalent chromium release over time from a pyrolyzed Cr-bearing tannery sludge

Scientific Reports, 2023
Pyrolysis in an inert atmosphere is a widely applied route to convert tannery wastes into reusable materials. In the present study, the Cr(III) conversion into the toxic hexavalent form in the pyrolyzed tannery waste referred to as KEU was investigated ...

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

Advanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...

Selective Nitrate Transmembrane Transport Through Adaptive Weak C─H Bonding Cyanostilbene Water Channels

Angewandte Chemie, EarlyView.
Here we demonstrate that weak HB CH donor cyanostilbenes promote water/ion transport through their ability to form less‐ordered transient water channels within the lipid bilayer with increased water permeability and NO3−/ Cl− selectivity. ABSTRACT Transmembrane water transport strongly depends on how dynamic, translocating water clusters are stabilized

New Discoveries in the Realm of Metal–Metal Multiple Bonds:[η5-(C5Me5)Co2], the First Organometallic Multiple-Bond Complex without Bridging Ligands [PDF]

, 1991
Double bond, yes or no? That is the poignant question in the case of the complex [Cp*CoCoCp*] prepared by J.J. Schneider et al. The Co-Co distance and the number of electrons suggest a double bond, while the H-1-NMR spectrum and the poor reactivity ...
