High-Performance Zinc–Sulfur Batteries High-performance Zn-S battery is achieved by employing a hybrid electrolyte using low-cost protic solvent (ethylene glycol) as the co-solvent in water. The designed can regulate water activity and suppress sulfur side reactions aqueous electrolytes, forming an in-situ solid state inter-phase (SEI) layer on Zn anode to facilitate reversible stripping/platin...

Metal-organic frameworks (MOFs) derived Co-based catalysts have received extensive attention in the chemoselective hydrogenation of nitroarenes, while they usually require a lot solvent during synthesis and identification active species. This study explores solid-phase strategy to obtain MOF precursors without using any solvent, which is then foamed pyrolyzed synthesize Co@NC-X catalyst. It was...

A series of copper and cobalt substituted nanospinel ferrites have been synthesized by the hydrothermal method. These compounds were characterized by FT-IR, XRD, EDX, SEM and VSM techniques. All of the synthesized nanospinel ferrites were found to be highly efficient and magnetically recoverable in the solvent-free synthesis of substituted 2,6-(2-hydroxybenzyl)-phenols (trisphenols). A wide ran...

Truncated hemoglobins (trHbs), are a distinct and newly characterized class of small myoglobin-like proteins that are widely distributed in bacteria, unicellular eukaryotes, and higher plants. Notable and distinctive features associated with trHbs include a hydrogen-bonding network within the distal heme pocket and a long apolar tunnel linking the external solvent to the distal heme pocket. The...

Separation of Polycyclic Aromatic Hydrocarbons was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (V/V) as co-organic solvent in mobile phase at 40°C. Analysis of...

Control of intermolecular interactions is integral to harnessing self-assembly in nature. Here we demonstrate that control of the competition between hydrogen bonds and halogen bonds, the two most highly studied directional intermolecular interactions, can be exerted by choice of solvent (polarity) to direct the self-assembly of co-crystals. Competitive co-crystal formation has been investigate...
