Nanostructured TiO2 and TiO2-Ag antimicrobial thin films

Prasad R.G.S.V., Basavaraju D., Rao K.N., Naveen C.S., Endrino J., Phani A.R., Sri Vishnu College of Pharmacy, IN

Bacterial infection is one of the common clinical problems which can be prevented by coating the surgical instruments or implants with antibacterial properties. The high incidence of infections caused by either fungal or bacteria on [...]

A novel strategy for fabrication of mesoporous crystalline tin dioxide films with large pores and fully crystalline walls

Fattakhova-Rohlfing D., Rathousky J., University of Munich (LMU), DE

We have developed a new facile procedure for manufacturing crystalline thin films of tin oxide with a uniform mesoporous architecture and full crystallinity of the walls. The procedure is based on the evaporation-induced self-assembly of [...]

Preparation, properties and thermal control applications of silica aerogel infiltrated with solid-liquid phase change materials

Xiangfa Z., Hanning X., Jian F., Changrui Z., Yonggang J., HuNan University, CN

In the present work, silica aerogel saturated with erythritol as phase change materials (PCMs) was prepared by melt infiltration. The properties of the composite were determined by scanning electronic microscope (SEM), Fourier transformation infrared spectroscope [...]

Mesoporous Titanium Dioxide Sphere with Anatase-Type Crystalline Structure using Cyclodextrin as Templates for Nano-sized Pore with Narrow Size Distribution

Chung J.W., Kim H.-J., Kwak S-Y, Seoul National University, KR

Mesoporous titanium dioxide (CD-TiO2) sphere with pore diameter in several nanometers and narrow pore size distribution was prepared from beta-cyclodextrin (beta-CD) and titanium precursor via sol-gel reaction in aqueous acidic condition. beta-CD was used as [...]

Growth of Ge nanowires by chemical vapour deposition technique

Phani A.R., Grossi V., Passacantando M., Ottaviano L., Santucci S., National Institute of Nuclear Physic, IT

Germanium, Mn doped Ge nanowires have been synthesized using chemical vapor deposition with Au nanoparticles (with size ranging from 5nm to 10 nm) as nucleating centers (catalysts) and Germanium, Manganese powders as a source for [...]
