this study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. the size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (pcs) and transmission electron microscopy (tem). processing/formulation parameters for formation of the nanoparticles were studied to determine their effects o...

Well-dispersed palladium(0) nanoparticles with small and narrow size distributions were synthesized conveniently on a graphene oxide (GO) surface. The GO-supported nano-Pd(0) was found to be a highly efficient and recyclable catalyst for the carbonylative cross-coupling reaction between arylboronic acids and aryl and carboranyl iodides, respectively. Benzophenone and a series of carboranylaryl ...

Plasmonic, metallic nanostructures have attracted much interest for their ability to manipulate light on a subwavelength scale and related applications in various fields. In this work, parabola-like gold nanobowtie (PGNB) sapphire substrate was designed as nano-cavity confining waves nanoscale gap region. The near-field optical properties of the innovative PGNB structure were studied comprehens...

We employ a planar metamaterial structure composed of a split-ring-resonator (SRR) and paired nano-rods to experimentally realize a spectral response at near-infrared frequencies resembling that of electromagnetically induced transparency. A narrow transparency window associated with low loss is produced, and the magnetic field enhancement at the center of the SRR is dramatically changed, due t...

Selenium (Se) is an essential trace element with a narrow margin between beneficial and toxic effects. As a promising chemopreventive agent, its use requires consumption over the long term, so the toxicity of Se is always a crucial concern. Based on clinical findings and recent studies in selenoprotein gene-modified mice, it is likely that the antioxidant function of one or more selenoproteins ...

Nanostructures Formulation for Food Products: Advances in soft matter nanotechnology are increasingly being realised to offer smart and generic solutions in various production fields including food and agriculture industries [1]. In recent years there have been several studies reporting on nano medicinal applications of Lyotropic liquid crystalline (LLC) phases like in development of novel cont...

to resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  the assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process para...

pH-sensitive micelles with hydrophilic core and hydrophilic corona were fabricated by self-assembling of triblock copolymer of poly(methylacrylic acid)-poly(ethylene glycol)-poly(methylacrylic acid) at lower solution pH. Transmission electron microscopy and laser light scattering studies showed micelles were in nano-scale with narrow size distribution. Solution pH value and the micelles concent...
