Nano-sized tetragonal BaTiO₃ (BT) particles that are well dispersed in solution are essential for the dielectric layer in multilayer ceramic capacitor technology. A hydrothermal process using TiCl₄ and BaCl₂, as source of Ti and Ba, respectively, or the precursor TiO₂ as seed for the formation of BT, and poly(vinylpyrrolidone) (PVP) as a surfactant, was employed in this study to enhance both th...

Cinnamaldehyde (CA) is marginally soluble in water, making it challenging to evenly disperse it in foods, and resulting in lowered anti-A. flavus efficacy. In the present study, nano-dispersed CA (nano-CA) was prepared to increase its aqueous solubility. Free and nano-dispersed CA were compared in terms of their inhibitory activity against fungal growth and aflatoxin production of A. flavus bot...

Heated scallop-shell (HSS) nano-particles, prepared using a wet grinding mill, and microparticles were examined for their antibacterial activity against vegetative bacterial cells and spores. The median diameters of the nano-particles and micro-particles were approximately 20 nm and 30 µm, respectively. The antibacterial activity of HSS against Escherichia coli increased with an increase in con...

We report on the observation and measurement of transfer transverse angular momentum to birefringent particles several wavelengths in size. A trapped particle is much larger than nano-particles systems for which was previously investigated. The interacts more strongly with both trapping beam fluid surrounding it. This technique could be used studies diverse micro-systems. Thus, it can investiga...

Avoiding collision of nano-particles during manipulation operations and selecting the best route and lowest Atomic Force Microscopy (AFM) movement are major concerns in the area of nano-space. To apply the lowest force on the cantilever from fluid environment forces, we try to minimize AFM movements. Our proposed method calculates the optimum routing for AFM probe movement for nano-particles tr...

We study metallic nano-particles for light trapping by investigating the optical absorption efficiency of the hydrogenated amorphous silicon thin film with and without metallic nano-particles on its top. The size and shape of these nano-particles are investigated as to their roles of light trapping: scattering light to the absorption medium and converting light to surface plasmons. The optical ...

An improved SOFC anode with excellent stability against carbon deposition syngas as fuel is reported. The material Ni–La0.8Sr0.2FeO3 (LSF) composite synthesized by anhydrous impregnation. After reduction in wet H2 (3% H2O), the partially decomposes to SrLaFeO4 and exsolved Fe. Fe forms Ni–Fe alloy impregnated Ni. particle size of about 20–50 nm. nanoparticles disperse on surface La0.8Sr0.2FeO3 ...
