Gold Nanoshells in Biomedical Applications

Hydroxyapatite Synthesis Methodologies: An Overview

Hydroxyapatite (HAp) is the emerging most bioceramic, which is widely used in various biomedical applications, mainly in orthopedics and dentistry due to its close similarities with inorganic mineral component of bone and teeth. Synthetic HAp is known to be similar to naturally occurring HAp on the basis of crystallographic and chemical studies. Several methodologies have been investigated and ...

Asynchronous Design Methodologies: An Overview

Asynchronous design has been an active area of research since at least the mid 1950's, but has yet to achieve widespread use. We examine the benefits and problems inherent in asynchronous computations, and in some of the more notable design methodologies. These include Huffman asynchronous circuits, burst-mode circuits, micropipelines, template-based and trace theory-based delay-insensitive cir...

Magnetically mediated vortexlike assembly of gold nanoshells.

Gold nanoshells currently attract increasing research interests due to the important role in many subjects. For practical applications, random arrangement of the nanoparticles is often unfavored so that the assembly of gold nanoshells is becoming a central issue. We here proposed to utilize time-variant magnetic field to direct the assembly of gold nanoshells. It was discovered that the alterna...

Ancient Gold Mining Activities in India - An Overview

Gold was obtained through washing or panning of the river sands during initial periods of civilisation. With the advent of knowledge of metallurgical processing of ores it was recovered through mining of in-situ quartz reefs, and then from auriferous sulphide ores. The metal mining activities are evidenced in the form of large number of ‘ancient metal mines’ or ‘old workings’ and ‘placer mining...
