Novel orange pigmented, Gram-negative-staining, rod-shaped, non-motile, strictly aerobic strains designated NIO-S1(T) and NIO-S2 were isolated from the water sample of a pond adjacent to the coast and an algal mat from a fish pond, respectively, at Kakinada, India. Both strains were positive for oxidase, catalase and β-galactosidase activities. The predominant fatty acids in NIO-S1(T) were iso-...
The Kirkendall effect and Ostwald ripening were successfully combined to prepare uniquely structured NiO aggregates. In particular, a NiO-C composite powder was first prepared using a one-pot spray pyrolysis, which was followed by a two-step post-treatment process. This resulted in the formation of micron-sized spherical and hollow-structured NiO aggregates through a synergetic effect that occu...
A new input/output (NIO) library that provides block-oriented I/O was introduced with Java v1.4. Because of its complexity, creating network applications with the Java NIO library has been very difficult and build-in support for high-performance, distributed and parallel systems was missing. Parallel architectures are now becoming the standard in computing and Java network application programme...
Nickel oxide (NiO) and phosphotungstic acid (PTA) supported on a ZIF-8 (NiO-PTA/ZIF-8) catalyst was first synthesized and it showed high activity and good selectivity for the hydrocracking of Jatropha oil. The catalyst was characterized by SEM, SEM-EDS, TEM, N2 adsorption, FT-IR, XRD and XPS. Compared with the NiO-PTA/Al2O3 catalyst, the selectivity of C15-C18 hydrocarbon increased over 36%, an...
This paper reports the effect of post-laser irradiation on the gas-sensing behavior of nickel oxide (NiO) thin films. Nanocrystalline NiO semiconductor thin films were fabricated by a sol-gel method on a nonalkaline glass substrate. The NiO samples were irradiated with a pulsed 532-nm wavelength, using a Nd:YVO(4) laser beam. The effect of laser irradiation on the microstructure, electrical con...
In this work, we investigate the synthesis, along with structural and magnetic properties, of novel Mn-Co-NiO-based heterostructured nanocrystals (HNCs). The objective is to develop novel, well-structurally ordered inverted antiferromagnetic (AFM) NiO–ferrimagnetic (FiM) spinel phase overgrowth HNCs. Inverted HNCs are particularly promising for device applications because their properties more ...
Selective synthesis of nickel oxide nanowires and length effect on their electrochemical properties.
Nickel oxide nanostructures with different lengths have been easily synthesized by calcining nickel foil after soaking in LiOH solution of different concentrations. The measurements of electrochemical properties of these NiO nanostructures show that different lengths of NiO nanostructures would have different electrochemical properties and the NiO nanowires with the longest length have the larg...
A Gram-stain-positive bacterium, designated strain NIO-1109(T), was isolated from a marine sediment sample from Chorao Island, Goa, India. Phenotypic and chemotaxonomic characteristics and data from phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NIO-1109(T) was related to the genus Exiguobacterium . Strain NIO-1109(T) exhibited >98.0% 16S rRNA gene sequence similar...
Alloying nickel oxide (NiO) with lithium oxide (Li2O) at high Li concentrations may reduce NiO's band gap and expand its use as a light absorber in photocatalytic and tandem dye-sensitized solar cell technologies. In this work, we evaluate the viability of this alloy as a p-type hole transport material. We use embedded cluster models, along with unrestricted Hartree-Fock and complete active spa...
A new process for fabricating NiO exchange bias layers has been developed. The process involves the direct ion beam sputtering (IBS) of a NiO target. The process is simpler than other deposition techniques for producing NiO buffer layers, and facilitates the deposition of an entire spin-valve layered structure using IBS without breaking vacuum. The layer thickness and temperature dependence of ...
