Automated electrodeposition of bimetallic noble-metal nanoclusters via redox-replacement reactions for electrocatalysis

Author: Mkwizu, TS ; Mathe, Mahlanyane K ; Cukrowski, I Date: 2009 Nanoclusters of bimetallic composition involving platinum with gold or ruthenium were sequentially deposited via redoxreplacement of electrodeposited sacrificial Cu adlayers for controlling the deposition of the noble metals. These steps were ... Read more
An easy two-step microwave assisted synthesis of SnO2/CNT hybrids

Author: Motshekga, SC ; Kesavan Pillai, Sreejarani ; Ray, SS ; Jalama, K ; Krause, RWM Date: Nov 2011 Tin oxide (SnO2) - decorated carbon nanotube (CNT) heterostructures were synthesized by microwave assisted wet impregnation method. CNTs of three different aspect ratios were compared. The hybrid samples were characterized by powder X-ray ... Read more
Multiwall carbon nanotube/nickel oxide nanocompositecoatings: Sol-gel deposition and characterization

Author: Roro, Kittessa T Date: Sep 2011 Due to their unique electronic and optical properties nanocomposite materials have wide range of applications in solar energy conversion. In this study, multiwalled carbon nanotubes (MWCNTs)/Nickel oxide (NiO) nanocomposites were successfully ... Read more
Nano-electrochemical deposition of fuel cells electrocatalysts

Author: Mathe, Mahlanyane K ; Mkwizu, TS ; Cukrowski, I Date: Nov 2008 The paper reports on the development of automated electrochemical deposition method as a synthetic strategy for fabrication of catalytically-active thin-films (or nanostructured) materials, composed of platinum Group Metals (PGMs), with ...

Nanocauliflower like structure of CdS thin film for solar cell photovoltaic applications: Insitu tin doping by chemical bath deposition technique

Author: Wilson, KC ; Manikandan, E ; Basheer Ahamed, M ; Mwakikunga, Bonex W Date: 2014 We report on surface morphology changes of in situ tin (Sn) doped cadmium sulphide (CdS) thin film nanostructures prepared on a glass substrate using the chemical bath deposition (CBD) technique. Sn-doping in the presence of triethanolammine ... Read more
Nanomaterials for Sustainable Energy and Environmental Remediation

Author: Naushad, Mu ; Saravanan, R ; Kumar, Raju Date: Mar 2020 Nanostructured materials, especially, 1D, 2D and 3D nanostructures, and their engineered architectures are being increasingly used due to their potential to achieve sustainable development in energy and environmental sectors, providing a ...

RF electrodynamics in small particles of oxides - a review

Author: Srinivasu, VV Date: Jan 2008 RF electrodynamics, particularly, the low field rf absorption in small superconducting and manganite particles is reviewed and compared with their respective bulk counterparts. Experimental and theoretical aspects of the small particle ... Read more
Solar absorption and thermal emission properties of multiwall carbon nanotube/nickel oxide nanocomposite thin films synthesized by sol-gel process

Author: Roro, Kittessa T ; Tile, N ; Mwakikunga, Bonex W ; Yalisi, B ; Forbes, A Date: May 2012 Multiwall carbon nanotubes (MWCNTs)/nickel oxide (NiO) nanocomposites were successfully prepared by a sol–gel process and coated on an aluminium substrate. The MWCNTs were chemically functionalized and then added into NiO alcogels, and magnetic ... Read more
TEM and EELS studies of microwave-irradiation synthesis of bimetallic platinum nanocatalysts

Author: Mathe, Ntombizodwa R ; Coville, NJ ; Olivier, JE ; Scriba, Manfred R Date: 2014 Microwave-irradiation (MW) synthesis of nanostructured materials provides for the synthesis of metal nanoparticles, using fast and uniform heating rates. This procedure affords better control of the shape and size of the nanoparticles when ... Read more
