Quantum dot (QD) nanoparticles are highly promising contrast agents and probes for biomedical applications owing to their excellent photophysical properties. However, toxicity concerns about commonly used cadmium-based QDs hinder their translation to clinical applications. In this study we descr...

Two neuropeptides, orexin-A and orexin-B (also called hypocretin-1 and -2), have been implicated in sleep/wake regulation, feeding behaviors via the activation of two subtypes of G-protein-coupled receptors: orexin 1 and orexin 2 receptors (OX1R and OX2R). While the expression of orexins and ore...

Liquid membrane electrodes of myristate soaps of heavy metals, namely copper, cadmium, zinc, nickel, cobalt, strontium and barium in a benzene-n-butanol mixture were prepared. Each electrode showed nernstian response in common metal ion test solution. The range of concentration of the test solut...

The morphology of poly(3,3′diethyloxetane) fractions crystallized from the melt has been analyzed by polarized light microscopy and small angle light scattering. The superstructures that can be developed have been studied for a wide range of isothermal and non-isothermal crystallization conditi...

Vertically aligned zinc oxide (ZnO) nanorods (NRs) were successfully grown on Au/alkali-free glass substrates by chemical bath deposition (CBD) using the mixed aqueous solution of zinc nitrate hexahydrate [Zn(NO3)2 · 6H2O] and hexamethylenetetramine (HMT) (denoted by “ZnNit solution”). Even i...

The adsorption mechanisms and kinetics of zinc cations at the graphene oxide (GO) nanosheets-water interface were studied by experimental and theoretical approaches. Results showed that adsorption of zinc cations onto GO surface forms a monolayer and obeys Langmuir isotherm. Meanwhile, the kinet...

Kinetics of extra heavy oil upgrading in supercritical methanol with and without zinc nitrate hexahydrate as a precursor of a catalyst was studied. The reactions were carried out at 633 K, 653 K, 673 K and 693 K in a batch reactor. Reaction rate constants were calculated based on a four-lumped k...

Phase change materials (PCM) store large quantities of energy in small volumes due to the high values of latent heat involved during phase change (e.g., from solid to liquid). However, they often require low temperatures (i.e., supercooling below the melting point) to initiate solidification. He...

For ammonia flue gas desulfurization (FGD), the sulfite to sulfate oxidation is very critical for industrial applications. This paper reports a novel corona plasma-induced oxidation technique to convert concentrated ammonium sulfites to sulfates in an aqueous solution. The streamer corona plasma...

The heterogeneous oxidation of ammonium sulfite solution was investigated in stirred cell and packing column. The concentration range of sulfite is 0.05–4.7gmol/l and that of oxygen in the gas phase is 21–100%, temperature range is 30–75°C. The results indicated that there is a critical sulf...

A homogeneous catalyst system made up of [Co(NH3)6]2+/I− has been put forward to catalyze the oxidation of concentrated ammonium sulfite. The experiments were performed in a packed column with sulfite concentrations above 2.5 mol l−1, temperature range 20–65 °C, and oxygen partial pressure 0.0...

Electrochemical oxidation of sulfite ions offers an efficient and profitable approach to the conversion of sulfur dioxide, a harmful air pollutant, into valuable by-products via flue gas desulfurization. Here, the electrochemical oxidation of sulfite in near-neutral pH electrolytes is studied in...

A streamer corona plasma induced oxidation technique, which used the so called AC/DC power supply to convert high concentration ammonium sulfite to sulfate, was reported. The results showed that the sulfite oxidation rate was significantly higher than that in the forced air oxidation process. Re...

The objective of the present study was to detail the change of 4(5)-Methylimidazole (4-MI) in sulfite and sulfate reactions with different initial pH values.
