Nano-metal oxides: Exposure and engineering control assessment

Nano-Composite Metal Oxides for Electronic Noses

This program aims at producing the next generation of molecular chemical and biological sensors [1]. Is is an interdisciplinary effort to manufacture electronic "noses" from arrays of nanostructured metal oxide sensors, each of which is specific to a given gas. Specificity in nanostructured oxides is achieved by exploiting their structure sensitivity. The ongoing research focuses on the study o...

Tailoring nano-catalysts: turning gold nanoparticles on bulk metal oxides to inverse nano-metal oxides on large gold particles.

Highly active/stable inverse catalysts of nano-oxides on large gold particles are designed and tailored. For the gas-phase oxidation of alcohols as a model reaction, the experimental and theoretical results verify that the catalyst activity depends on the gold-oxide interface, and the anti-sintering feature of such an inverse structure endows the catalyst with high stability.

Preparation, Structure and Selected Catalytic Properties of La2CuO4 Nano Mixed Metal Oxides

The perovskite-structured La2CuO4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through Fourier transform infrared spectrosco...

Nano-Metal oxides induced sulforaphane production and peroxidase activity in seedlings of Lepidium draba (Brassicaceae)

Effects of different concentrations [0, 1, 5, 10, 20 and 40 mgL-1] of Fe3O4 and CuO nano-particles (nFe3O4 and nCuO) were investigated on sulforaphane (SFN) production level in 7-day-old seedlings of Lepidium draba at different time intervals (8 and 16 hrs). According to the results, the influence of the particles on SFN contentdepends on nano-particle (NP) concentrations, time of treatment as ...
