S. Balaji and B. Narayanamoorthy
The physical interactions of Platinum nanoparticles anchored on Vulcan® carbon XC – 72 (VC) over Nafion® - Polyethylene glycol - 6000 (PEG) polymer matrix nanocomposite were characterized by Fourier Transform – Infrared (FT-IR) spectra technique and surface morphology by Scanning Electron Microscope (SEM) analyses. The conductivity of the Pt nanoparticles embedded polymer nanocomposite membranes was measured using Electrochemical Impedance Spectroscopy (EIS) and the ORR studies were investigated using Cyclic Voltammetry (CV) and Linear Scan Voltammetry (LSV) under hydrodynamic conditions . The results show that VC over Nafion®-PEG polymer matrix nanocomposite exhibited a better improvement on their conductivity and comparable with neat Nafion® membranes hinting the possible use of the carbon over Nafion®-PEG matrix for improving the fuel cell efficiency for ORR with different Pt loading conditions.

An examination of specific cellular organelle-targeting nanotags using combined 3D Raman and SERS imagingPoster
We investigated the specific targeting of endoplasmic reticulum and trans-Golgi network in Chinese hamster ovarian cells using functionalised nanotags. The targeting was examined using the combined 3D SERS and Raman imaging method.
Fluorescent Nanoprobes Confined in a Drop as a novel Sensing Platform for Detection of Metal Species at Trace LevelPoster
In the last years, a great interest has arisen concerning the design and development of new optical probes for the sensitive and selective detection of chemical species making use of miniaturized and environmental friendly methods. In this sense, quantum dots (QDs) and metal nanoclusters (NCs) have important optical properties to be applied in analytical systems as fluorescent probes.READ MORE
