Computer-Aided Design of Ionic Liquids as CO2 Absorbents

Computer-Aided Design of Ionic Liquids as CO2 Absorbents

Better by design: Using a continuum model makes it possible to distinguish between the chemical and physical absorption of CO2 in ionic liquids. The ionic liquids showing chemical adsorption were further narrowed down to “good” candidates, in which a facile desorption is feasible according to a calculated energy criterion. This criterion was determined by correlating the calculated Gibbs free energies with experimental capacities.

How the [NiFe4S4] Cluster of CO Dehydrogenase Activates CO2 and NCO

How the [NiFe4S4] Cluster of CO Dehydrogenase Activates CO2 and NCO−

Two sides of the same coin: CO2 and NCO are both activated at Ni and Fe2 of the [NiFe4S4] cluster of CO dehydrogenase and bind as bridging ligands between the two metal atoms. Insights from true atomic resolution structures draw a clear picture of the chemical nature of the ligands: activation of both the substrate CO2 and the inhibitor NCO occurs by formal two-electron reduction.

Oxygen Reduction Mediated by Single Nanodroplets Containing Attomoles of Vitamin B12: Electrocatalytic Nano-Impacts Method

Single vitamin B12 (VB12) nanodroplets are used to mediate the reduction of oxygen in neutral buffer (see picture). The mechanism of oxygen reduction mediated by single VB12 droplets is revealed as via both CoII and CoI reduced from CoIII in VB12 through one- or two-electron transfer followed by the four-electron reduction of oxygen.

Synthesis of Robust Precursors for the Controlled Fabrication of (6,6), (8,8), (10,10), and (12,12) Armchair Single-Walled Carbon Nanotubes

We report four robust precursors for the rational synthesis of isomerically pure armchair single-walled carbon nanotubes (SWCNTs). The precursor structures are specially “programmed” for fabrication of ultrashort (6,6), (8,8), (10,10), and (12,12) singly capped nanotubes bearing three CNT segments, effective seeds for controlled growth of helicity-pure SWCNTs by metal-catalyzed epitaxial elongation.

Indolo[3,2-c]quinoline G-Quadruplex Stabilizers: a Structural Analysis of Binding to the Human Telomeric G-Quadruplex

Indolo[3,2-c]quinoline G-Quadruplex Stabilizers: a Structural Analysis of Binding to the Human Telomeric G-Quadruplex

A much higher IQ: We report indolo[3,2-c]quinoline (IQc) derivatives with two weak basic side chains as potent and selective human telomeric (HT) G-quadruplex (G4) stabilizers. Biophysical data show that stabilization involves the binding of two ligands which induces a conformational rearrangement of the HT G4 structure. Moreover, selected derivatives showed selective antiproliferative activity toward human malignant cell lines.

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Super phenolic solvents: Biomass-derived carbohydrates represent an attractive source of renewable carbon due to their many chemical and biological conversion routes to fuels and chemicals. In a nonenzymatic biomass deconstruction process for producing carbohydrates, separating a mixture of γ-valerolactone (GVL) and water used in the process is a key step. We demonstrate that phenolic solvents are highly effective at separating GVL and can be used to detoxify the biomass-derived mixture for fermentation.

Selective Oxidation with Aqueous Hydrogen Peroxide by [PO4{WO(O2)2}4]3− Supported on Zinc-Modified Tin Dioxide

Selective Oxidation with Aqueous Hydrogen Peroxide by [PO4{WO(O2)2}4]3− Supported on Zinc-Modified Tin Dioxide

Unconditional support: The supported phosphorus-containing tetranuclear peroxotungstate (PW4) catalyst PW4-Zn(0.8)/SnO2 can act as an efficient and reusable heterogeneous catalyst for the selective oxidation of various types of organic substrates such as alkenes, amines, silanes, and sulfides with aqueous H2O2 as the terminal oxidant. The catalytic performance of PW4-Zn(0.8)/SnO2 was much higher than those of the corresponding homogeneous analogue and the previously reported tungstate-based supported catalysts.

Difluorinated 6,13-Bis(triisopropylsilylethynyl)pentacene: Synthesis, Crystallinity, and Charge-Transport Properties

Difluorinated 6,13-Bis(triisopropylsilylethynyl)pentacene: Synthesis, Crystallinity, and Charge-Transport Properties

Crystal clear: Fluorination of 6,13-bis(triisopropylsilylethynyl)pentacene leads to a stable organic semiconducting material. Field-effect transistors are fabricated by solution-phase deposition, and the hole-transporting channels show contact-induced self-assembly with highly ordered edge-on crystallites. The analysis of a transfer characteristic reveals nonidealities related to the gate-bias-dependent mobility and the contact resistance.

From Electrochemical Interface to Interphase (2D→3D) on Ionomer Membranes

Face to phase: A method whereby the electrochemical contact between a proton exchange membrane and a gas diffusion electrode is enhanced from 2D to 3D by incorporating a conducting polymer into the near-surface region of the ionomer membrane is reported. Thus, electrochemical reactions in a spatially extended zone of the electrolyte membrane can be triggered, increasing the electrochemical response by two orders of magnitude.
