Microemulsion-based synthesis is found to be a versatile route to synthesize a variety of nanomaterials. The manipulation of various components involved in the formation of a microemulsion enables one to synthesize nanomaterials with varied size and shape. In this tutorial review several aspects of microemulsion based synthesis of nanocrystalline materials have been discussed which would be of ...

We have developed a speech synthesis system based on the speech production process. In the system, control parameters for the vocal tract shape and vocal cords are interactively set in order to produce speech output. Such an intuitive system is useful not only for speech research but also for teaching materials in speech science. In this paper, a network-based articulatory speech synthesis syst...

an efficient, simple and convenient route is described for the synthesis of biscoumarin (3,3'-(arylmethylene) bis (4-hydroxy-2h-chromen-2-one)) by using of recyclable catalyst tio2@ksf. in this method, we synthesis biscoumarin derivatives via 3multi-component reactions (3mcrs) of two equivalent 4-hydroxycoumarin with one equivalent of aromatic aldehydes using 20 mg nano tio2@ksf as homogen...

Functional materials impact every area of our lives, from electronic and computing devices to transportation health. Here we examine the relationship between synthetic discoveries scientific breakthroughs that they have enabled. By tracing development some important examples, explore how why were initially synthesized their utility was subsequently recognized. Three common pathways are identifi...

The effect of cooling process for the synthesis and the superconductivity properties of Pb-substituted Bi-based materials, has been investigated. The preparation condition for the formation of (2,2,2,3) phase has been examined. The influence of thermal condition of the synthesis and quenching on the critical temperature and the content of 110K phase was investigated. Results of the ac-susceptib...
