The effects of nanosize copper oxide and basic copper carbonate on the physical and mechanical properties of flakeboards were investigated according to ASTM Standard D-1037, and the curing process of phenol formaldehyde (PF) resin containing copper compounds was further investigated using dynamic differential scanning calorimetry (DSC). The results showed that nanosize copper oxide had no or sl...

In this paper, we report the experimental results on the optical properties of oligo-phenylene vinylenes (OPVs) formed in nanosize pores of porous silicon substrates. Strong modifications of the photoluminescence properties of nanosize aggregation of OPVs were observed at

Speciation and possible reaction paths of nanosize copper pollutants extracted with a RTIL (room-temperature ionic liquid ([C4mim][PF6], 1-butyl-3-methylimidazolium hexafluorophosphate)) have been studied in the present work. Experimentally, in a very short contact time (2 min), 80-95% of nanosize CuO as well as other forms of copper (such as nanosize Cu, Cu2+, or Cu(II)(ads) (in the channels o...

Uniform dispersions of magnesium fluoride particles of different morphologies were prepared by precipitation in aqueous solutions. The resulting cubic, prismatic, and platelet-like nanosize solids had single crystal structure with X-ray pattern characteristic of the mineral sellaite. In contrast, two kinds of polycrystalline MgF2 spheres were obtained by aggregation of the nanosize subunits. Th...

Following recent technological advancements, a great attention has been paid to mechanical behaviour of structural elements nanosize. In this study, some solutions problems bars nanosize is examined using Eringen’s two-phase nonlocal elasticity. Assuming the fraction coefficient part material small, perturbation expansion with respect it performed. With procedure, original problem broken into s...

The preparation methods, ORR performances, and synergistic mechanisms of carbon-supported high-metal-density electrocatalysts (including nanosize NPs atomic-level structures) are systematically summarized.

titanium dioxide is widely used in the manufacturing of paints, varnishes, lacquer, paper, paperboard, printing inks, rubber, floor covering, and ceramics and so on. white titanium dioxide pigment has been produced by two main processes. the sulfate and the chloride processes. each of these two routes requires different feedstocks. however, economic and environmental pressures are shifting the ...
