High Efficiency Preparation, Structure and Properties of Silicon Nano-Crystals by Induction Plasma Method

Wen-zhi Yang, Wei-ming Huang, Qiang Zheng, Wei Huang, Zi-ming Chen, Fu-jun Shang and Bao-yu Zhang
Free-standing silicon nano-crystals were synthesized from silicon multi-crystals with high efficiency by induction plasma method. The particle morphology and distribution of nano powder were significantly influenced by powder feed rate, induction plasma power and the ratio of sheath gas. The average particle size monotonously increased with the increase of powder feed rate.

Epitaxial Growth of Ruthenium Dioxides on Ru(0001) Surface

C.-H. Nien and M.S. Zei
The epitaxial growth of the RuO2 clusters on Ru(0001) electrode formed by electrooxidation in HClO4 solution has been studied by ex-situ reflection high energy electron diffraction (RHEED), low energy electron diffraction (LEED) and Auger electron spectroscopy (AES) after emersion. The LEED pattern for the RuO2 clusters on Ru(0001) exhibits a (1 x 1) phase, while both Ru-oxide and substrate reflections are observed by RHEED, so that the crystal structure of RuO2 clusters has been determined by RHEED rather than LEED.

Ethanol Based Vesicular Carriers in Transdermal Drug Delivery: Nanoethosomes and Transethosomes in Focus

Lalit Kumar, Shivani Verma, Kuljit Singh, Deo Nandan Prasad and Amit Kumar Jain
Transdermal route is one of the attractive routes for drug delivery due to its easy accessibility. Effective delivery of bioactive molecules through skin is however, still a challenge. The development of vesicular formulations has generated some promising solutions to the problems associated with drug delivery not only related to drugs but also those of barriers like skin.

How Bibliometric Indicators Should Be Used to Assess Excellence in Science and Technology

Claudio Nicolini
In order to identify the best standards for the assessment of world-wide scientific performances at the level of both individuals and institutions, we have carried out a comparative analysis of the relative scientific and technological level of individual scientists and individual scientific institutions for given fields and disciplines, using the prominent bibliometric indicators (patents, citations, publications SCI, impact factor).
