Unique microstructured nickel ammonium phosphate Ni(NH4)2(PO3)4$4H2O and Ni(NH4)2(PO3)4$4H2O/GF composite were successfully synthesized through the hydrothermal method with different graphene foam (GF) mass loading of ...

Defects introduced by the solid state reactions between tungsten and silicon carbide have been studied using deep level transient spectroscopy (DLTS) and Laplace DLTS. W/4H-SiC Schottky barrier diodes were isochronally ...

NiO/activated carbon (AC) composites were successfully synthesized via a hydrothermal reflux process as an electrode material for carbon monoxide (CO) gas sensor application. The X-ray diffraction (XRD) analysis was used ...

In this work, we report the time-dependent morphological evolution of the as-prepared vanadium dioxide (VO2) and its electrochemical performance for supercapacitor applications. VO2 with different morphologies (microspheres ...

Vanadium dioxide thin films nanostructures were synthesized by pulsed laser deposition on soda lime glass at a substrate temperature of 600°C and the effects of the oxygen deposition pressure on the crystalline structure ...

ZnAl2O4 nano-powders have been successfully prepared via citrate sol-gel technique. All powder samples were annealed at 600 °C for 1, 2, and 3 h. Thermogravimetric analysis (TGA) confirmed that the minimum annealing ...

The effects of gamma irradiation and stearic acid, alone and in combination, on functional, structural, and molecular characteristics of high amylose maize starch (Hylon VII, 60% amylose) were studied. Stearic acid (0, ...

Mg1.5Al2O4.5:x% Eu3þ (0 x 2) nanopowders were successfully synthesized via sol–gel method. The X-ray diffraction (XRD) spectrum revealed that the Mg1.5Al2O4.5:x% Eu3þ matches the single phase of face-centred cubic MgAl2O4. ...

The nature of letsoku and related clayey soils, traditionally used by indigenous Southern African communities for a wide range of purposes, was explored. Thirty nine samples were collected from Botswana, Lesotho, Swaziland, ...

Gypseous soils occur in the western arid and semi-arid regions of South Africa and Namibia. These soils exhibit a complex nature and abnormal behaviour due to their gypsum content and as such they have become more ...
