NICKEL HYDROXIDE NANORIBBONS FOR EFFICIENT WATER SPLITTING AND DIRECT METHANOL FUEL CELL
Oxygen evolution reaction (OER) and methanol oxidation reaction (MOR) are very important reactions in hydrogen harvesting system and direct methanol fuel cell (DMFC). However, these two reactions are sluggish processes, due to the multi-proton coupled reactions. In this work, we report the first …

CFD analysis of reactive crystallisation in stirred tanks : a focus on nickel hydroxide
The recovery of metal values from aqueous streams via precipitation, or reactive crystallisation, is both an economically and environmentally significant unit operation in a wide spectrum of industries. However, the control and operability of these systems is hampered by the limited fundamental …

The effects of crystal seeding on the handling characteristics of nickel hydroxide sludge
… technique on certain handling characteristics of nickel hydroxide sludge and to investigate the changes in sludge particle properties that mediated any changes in those characteristics. A continuous-flow nickel hydroxide precipitation reactor was operated with and without solids recycle to produce …

Adsorption of dextrin onto sulphide minerals and its effect on the differential flotation of the Inco matte
… 11.7, which was established to be the i.e.p. of nickel hydroxide. For Cu2S, the adsorption was much lower and did not exhibit any pH dependence. Electrokinetic and co-precipitation measurements confirm such observations. While the zeta potential-pH curves for Ni3S2 and freshly precipitated …

Deposition and characterisation of nickel oxide based coatings for advanced glazing applications
This thesis is a comparative study of nickel oxide based thin films for use as a counter electrode in a variable transmittance electrochromic device. Coatings have been prepared using anodic electrodeposition, colloidal precipitation and radio frequency (r.f.) sputtering. Systematic studies of the …
