White Emitting Magic Sized CdSe Nanoclusters Using Edible Oils: A Green Approach.

Herein; we present a green synthesis method for magic sized nanoclusters (MSNCs) of CdSe. The formation of MSNCs was examined using various edible oils viz; olive oil; mustard oil; castor oil; coconut oil and cod liver oil as capping agents. The source of Selenium is cyclo-octeno-1;2;3-selenadiazole which was decomposed (typically at 150 °C) in high boiling solvent.

Co/Co₃O₄ Based Nanoparticles and Their Polymer Composites for Tuned Electromagnetic Interference Shielding Application.

The magnetic properties of the metal nanoparticles (NPs) can play remarkable role in electromagnetic interference shielding (EMI Shielding) of many defence and commercial electronic devices. In the present work, coconut oil and PVA capped magnetic cobalt/cobalt oxide nanoparticles (Co/Co₃O₄ NPs) were synthesized by chemical reduction method and impregnated in polymer matrix to verify their EMI shielding behaviour. The coconut oil capped Co/Co₃O₄ NPs with presence of hcp and fcc phases were prepared in the size domain of 7-10 nm and the effect of surfactant (the oil) on size and oxidation state was studied by varying the ratios.

Ternary metal selenide/MWCNT/PANI: potential n-type nanohybrids for room-temperature thermoelectric applications.

Lead-free novel n-type ternary nanohybrids were fabricated by blending separately synthesized, diamond like I-III-VI and I-V-VI (I-Cu, Ag, III-In, V-Sb, VI-Se) nanocrystals (NCs) in a multi-walled carbon nanotube (MWCNT) and polyaniline (PANI) matrix. A thermoelectric study of these nanohybrids was performed at room temperature in order to understand their utility as potential thermoelectric materials for advanced applications. Electrical conductivity, thermal conductivity and Seebeck coefficient were measured and the thermoelectric performance was evaluated at room temperature.

Selective Synthesis of or -HgS Nanocrystals via Core/Shell Formation Using Surface Modified CdS Quantum Dots.

Chalogenides (CdS, CdSe, ZnSe etc.) are well known to undergo cation exchange reactions with other cations, including metals. The cation exchange methods are highly efficient in obtaining core/shell as well as alloy type of nanostructures.

Chemically designed Pt/PPy nano-composite for effective LPG gas sensor.

Simultaneous in situ reduction of hexachloroplatinic acid by the amine group in the pyrrole monomer and oxidation of pyrrole to form polypyrrole (PPy) was examined. The reactions were performed at various temperatures to understand the degree of reduction of platinum precursor as well as doping of polypyrrole with Pt(II) chloro-complex. Spectroscopic images revealed different morphologies for the Pt/PPy nano-composite prepared at various temperatures.
