The nanosized powders have gained attention to produce materials exhibiting novel properties and for developing advanced technologies as well. Nanosized exhibit substantially favourable qualities such improved catalytic activity, augmentation in reactivity, reduction melting temperature. Several researchers pointed out the influence of ultrafine aluminium (∼100 nm) nanoaluminium (<100 on bur...

BACKGROUND Both thermotherapy and arsenic have been shown to be active against a broad spectrum of cancers. To reduce the limitations of conventional thermotherapy, improve therapeutic anticancer activity, reduce the toxicity of arsenic on normal tissue, and increase tissue-specific delivery, we prepared a nanosized As2O3/Fe3O4 complex (Fe3O4 magnetic nanoparticles encapsulated in As2O3). We as...

AIMS To assess the impact of reaerosolization from liquid impingement methods on airborne virus sampling. METHODS AND RESULTS An AGI-30 impinger containing particles [MS2 bacteriophage or 30-nm polystyrene latex (PSL)] of known concentration was operated with sterile air. Reaerosolized particles as a function of sampling flow rate and particle concentration in the impinger collection liquid w...

We propose a generalized treatment of the drag force of a spherical particle due to its motion in a laminar fluid media. The theory is equally applicable to analysis of particle diffusion and electric mobility. The focus of the current analysis is on the motion of spherical particles in low-density gases with Knudsen number Kn>>1. The treatment is based on the gas-kinetic theory analysis of dra...

Manganese-zinc-ferrite nanoparticles (Mn(0.5)Zn(0.5)Fe(2)O(4), MZF-NPs) prepared by an improved co-precipitation method and were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Then thermodynamic testing of various doses of MZF-NPs was performed in vitro. The cytotoxicity of the Mn(0.5)Zn(0.5)Fe(2)O(4) nanoparticles in v...

Zinc ferrite nanoparticles have been synthesized by the co-precipitation method where Polyethylene Glycol act as capping agent. The sample structure and morphology of product were analysed powder XRD, FTIR, U-V visible spectroscopy scanning electron microscope (FE-SEM). prepared NPs annealed at varying temperatures such 500℃, 600℃ 700℃. XRD data confirms presence nanosized ZnFeO particles X-ray...

In topical administration of antifungals, the drugs should pass the stratum corneum to reach lower layers of the skin in effective concentrations. Thus, the formulation of antifungal agents into a suitable delivery system is important for the topical treatment of fungal infections. Nanosized colloidal carriers have gained great interest during the recent years to serve as efficient promoters of...

aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. this contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. the method is ba...
