In this study, multi wall carbon nanotubes (MWCNTs) were synthesized by Chemical vapor deposition (CVD) method using two different catalysts (Fe nanoparticles) and (Ni nanoparticles) with  two different substrates: Quartz and Alumina. Acetylene gas was used as a carbon source and Argon as a carrier gas at different temperatures and different times to study the effects of these parameters on CNT...

A hygrometer is an apparatus that measure humidity. Modern electronic devices use temperature of condensation or change in electrical capacitance to measure humidity difference. Humidity sensors are employed to provide an indication of moisture levels in the environment. To measure moisture level, various technologies are used. A capacitive type moisture sensor consisting of nanoporous thin fil...

Platinum nanoparticles with a mean size of 1.7 nm were synthesized by reduction in sodium acetate solution in 1,2-ethanediol. The particles were then functionalized with dodecylamine, dodecanethiol, and omega-mercapto-undecanoic acid (MUDA). Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) showed important variations of the particle surface state with fu...

Proniosomal drug delivery system is a stable provesicular in nanotechnology to overcome the drawbacks associated with other vesicular systems. These are water-soluble pro-vesicular carriers coated non-ionic surfactant which on hydration give niosomes. The encapsulated and shows systemic targeted of poorly soluble drugs increased bioavailability decreased side effects. Here we have covered chara...

Liquid can be instilled into the pulmonary airways during medical procedures such as surfactant replacement therapy, partial liquid ventilation, and pulmonary drug delivery. For all cases, understanding the dynamics of liquid distribution in the lung will increase the efficacy of treatment. A recently developed imaging technique for the study of real-time liquid transport dynamics in the pulmon...
