Nano materials are at the frontier of research

Abstract

research and review articles were published in volume 2 in 2018. Ghann & Uddin1 investigated the synthesis and characterization of CdSeS/ZnS quantum–dot–gold nanoparticles hybrids (denoted as QD–GNP) , which is a composite structure of semiconductor nanomaterial and metal nanoparticles. Its wavelength of maximum absorption is different from the gold nanoparticles and the quantum dot. And strong photoluminescence quenching was observed in this hybrid. The interaction of this hybrid with terahertz radiation shows the unique terahertz signal of the un conjugated gold nanoparticles and quantum dots versus the conjugated forms. The results indicate that the hybrid gold nanoparticle and quantum dot will have great potential for other optical application. Abraham et al.,2 prepared multiwalled carbon nanotube based styrene butadiene rubber nanocomposites. Imdazolium type ionic liquid was found to facilitate the dispersion of MWCNT in polymer matrix and to act as accelerators for the sulphur vulcanisation of SBR composites and to be helpful for the formation of three dimensional network of MWCNT in rubber matrix. Phul et al.,3 reported a synthesis method of copper nanoparticles by wet chemical reduction using L–ascorbic acid as reducing agent. The as–synthesized nanoparticles have cubic structure with an average particle size of 3 nm, with10times higher surface area as compared to the literature. The fabricated Cu nanoparticles showed noteworthy enhancement in the degradation of Rhodamine B organic dye when used as catalyst for its degradation under both dark and light conditions.
