abstract: application of atomic force microscope as a manipulator for pushing-based positioning of nano-particles has been of considerable interest during recent years. however a detailed modeling of the interaction forces and control on the afm tip is important for prosperous manipulation control, a reliable control of the afm tip position during the afm-based manipulation process is a main is...

Thermally responsive polymer-metal nanoparticle composites couple the ability of certain metal nanoparticles to convert external stimuli to heat with polymers that display sharp property changes in response to temperature changes, allowing for external control over polymer properties. These systems have been investigated for a variety of biomedical applications, including drug delivery, microfl...

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.

In this paper we investigate for the first time the near-field optical behavior of two-dimensional Fibonacci plasmonic lattices fabricated by electron-beam lithography on transparent quartz substrates. In particular, by performing near-field optical microscopy measurements and three dimensional Finite Difference Time Domain simulations we demonstrate that near-field coupling of nanoparticle dim...

a new nano-sized lead(ii) coordination polymer, [pb(2-bpdh)(no3)2]n (1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4-hexadiene)}, was synthesized by a sonochemical method. the structure of 1 may be considered coordination polymer of lead(ii) consist of metallocyclicchains formed by bridging no3- and 2-bpdh ligands. the thermal stability of compound was studied by thermal gravimetric and differen...

the microfiltration 0.2 µm cellulose acetate (ca) membrane was modified by embedding antibacterial silver nano-particles in the membrane pores. this novel technique was developed to enhance the capability of the microfiltration membrane for removing microorganism including bacteria. the prepared membrane was characterized using scanning electron microscopy (sem), energy-dispersive x-ray spectro...

background and aims. polymethyl methacrylate (pmma) is widely used for the fabrication of removable prostheses. silver nano-particles (agnps) have been added to pmma because of their antimicrobial properties, but their effect on the mechanical properties of pmma is unknown. the aim of this study was to investigate the effects of agnps on the tensile strength of pmma. materials and methods. for ...

the aim of this study was to examine the adverse effects of zinc nanoparticles on hematological indices of trout and investigate the improvement of these indices after vitamin c treatments. this study assesses the protective role of vitamin c in fish exposed to zno nps. two concentrations of zno-nps (40 and 80 mg l-1) and two doses of vitamin c (400 and 800 mg per kg of feed) were used to treat...
