Room temperature, water-based, microreactor synthesis of gold and silver nanoparticles

by Inderscience Publishers  (Apr. 14, 2009)

Synthesis of gold and silver nanoparticles at room temperature using a polydimethylsiloxane (PDMS) microreactor has been reported. The reactions have been performed using aqueous metal salt solutions and borohydride reducing agent with tri-sodium citrate as the capping agent. Effect of concentration of reducing agent on the optical properties of ...

Metallic nanoparticles: synthesis, characterisation and application

by Inderscience Publishers  (Jan. 24, 2011)

Colloidal sphere-like gold nanoparticles were prepared from an HAuCl4 aqueous solution by the chemical reduction method and by using X-ray irradiation, while rod-like gold nanoparticles were synthesised according to the seed-mediated growth method and by sonoelectrochemistry. Gold nanoparticles exhibit fcc structure. Sphere-like gold nanoparticles ...

Preparation, characterisation and photocurrent study of sol–gel–derived Al, Mg–doped ZnO transparent thin films

by Inderscience Publishers  (Mar. 17, 2014)

In this work, sol–gel spin–coating was employed to prepare ZnO, Al–doped ZnO (AZO) and Mg–doped ZnO (MZO) thin films onto glass substrates. Structural properties and surface morphologies of as–prepared films were characterised by X–ray diffraction (XRD) and scanning electron microscope (SEM) while their optical properties were scrutinised from ...

Study on synthesis and photocatalytic activity of novel visible light sensitive photocatalyst Ag

by Inderscience Publishers  (Apr. 8, 2013)

Silver orthophosphate nanoparticles have been synthesised by precipitation of AgNO3 and H3PO4 in presence of oleylamine and other solvents like toluene, and ethanol at room temperature. Particle sizes of silver orthophosphate nanocrystals can be controlled by adjusting the amount of water. The ...

S/CdS nanorod–array heterojunctions for efficient photoelectrochemical water splitting

by Inderscience Publishers  (Jan. 8, 2014)

Oriented CdS nanorod arrays (NRAs) and their heteorojunctions formed with Ag2S nanoparticles have been successfully prepared via a one–step hydrothermal method and a successive ionic layer adsorption and reaction (SILAR) process. Their morphology, structural, and optical properties were characterised by scanning electron microscope, transmission ...

High temperature microwave-assisted synthesis and the physico-chemical characterisation of mesoporous crystalline titania

by Inderscience Publishers  (Aug. 18, 2010)

Mesoporous TiO2 with nanocrystalline architecture has been synthesised by using microwave-assisted high temperature method using polymeric surfactant. The polymeric template was removed by stepwise carbonisation process. The structural order, band structure and the textural parameters of the calcined mesoporous titania were investigated by using ...

Nitrate and Nitrite Levels of Potable Water Supply in Warri, Nigeria: A Public Health Concern

by National Environmental Health Association (NEHA)  (Jan. 31, 2010)

In this study, the authors investigated the nitrate and nitrite in different water sources (surface water, shallow well water, and borehole water) in the market and industrialized areas of Warri in the Niger Delta area of Nigeria. The authors’ goal was to find the comparative levels of nitrates and nitrites from these two parts of the community. ...

Novel nano-structured materials: synthesis and application

by Inderscience Publishers  (Jan. 24, 2011)

Novel nano-structured materials: nano-particle materials like V-SiO2, TiO2 and nano-sized pore materials like Si-MCM-41, Ti-MCM-41 and Al-MCM-41Analogues were successfully synthesised using different methods: precipitation, sol-gel, micro-emulsion and hydrothermal treatment. These obtained ...
