Autor: Nirmalya K. Chaki, Vijayamohanan K. Pillai, Subhramannia Mahima, Jadab Sharma, Bhalchandra Kakade

Publikováno v: Journal of Nanoscience and Nanotechnology. 7:2139-2150

The role of polyfunctional organic molecules in the synthesis of differently shaped metallic nanostructures and their assembly is investigated. These molecules could be used as spacer ligands and also for surface passivation of nanoparticles, especia

Highly resolved quantized double-layer charging of relatively larger dodecanethiol-passivated gold quantum dots

Autor: Subhramannia Mahima, Santosh K. Haram, Bhalchandra Kakade, Kunjukrishna P. Vijayamohanan, Jadab Sharma, Nirmalya K. Chaki

Publikováno v: Journal of Applied Physics. 96:5032-5036

Monolayer-protected quantum dots (Q-dots) show multivalent redox property, popularly known as the quantized double-layer (QDL) charging phenomena. In this report, we demonstrate the QDL behavior of the larger-sized Au Q-dots (ca.3.72nm) protected wit

Solvent-Assisted One-Pot Synthesis and Self-Assembly of 4-Aminothiophenol-Capped Gold Nanoparticles

Autor: Kunjukrishna P. Vijayamohanan, Bhalchandra Kakade, A.B. Mandale, Subhramannia Mahima, Renu Pasricha, Jadab Sharma

Publikováno v: The Journal of Physical Chemistry B. 108:13280-13286

Single-step preparation of smaller sized (ca. 3 nm, approximate composition Au923ATP241) gold nanoparticles (AuNPs) followed by their self-assembly is demonstrated using 4-aminothiophenol (ATP) as a reducing agent in water/N,N-dimethylformamide (DMF)
