Day I -22nd Feb.
Technical
Session-I
The chairperson
for the first technical session was Prof. Julio B Fernandes. The session started
with presentation on carbon supported catalyst for the electro-Oxidation of Methanol
in Fuel cells by Smt. P.V. Samant, dept. of Chemistry, Govt. College of Arts, Science
and Commerce, Sanquelim-Goa. She started her presentation by giving a overview on
fuel cells saying that fuel cells have been the recent trends in research that focus
on the use of different combinations of noble or other metals as catalysts. She
said that direct methanol fuel cells are environmentally sound power source for
practical use in vehicles. She spoke on the preparation metal catalysts supported
on novel carbon materials, including carbon nanotubes and carbon xerocels.
This
presentation was followed by a presentation on “Nano TiO2 (Titanium Oxide):a
versatile photocatalyst” by Ms. Madhavi Naik, St.Xavier’s College, Mapusa on the
topic. She began her presentation with an introduction to photocatalyst. She spoke
about the advantages of Nano TiO2 in semiconductors, resistance to corrosion.
She spoke about the procedure of Doping TiO2 that is the mechanism of
photosysthesis, characterization with XRD results. She spoke about the photocatalyctic
activity of TiO2 and doped TiO2. She spoke about the applications
of TiO2 in detoxification, H2O treatment, air cleaning, anti
fogging of glass and medicinal fields.
This
was followed by the paper presentations. Ms. Prita Pant, BITS,Goa
spoke about development of novel and cost effective precursor based chemical methodology
for synthesis of single phase Ni-Zn ferrite nanopowder. Dr. harsha uskaikar,PES College
spoke about synthesis of titannates by citrate method. Ms. Swati naik,
Goa University
spoke about synthesis and characterization of manganese oxide. Dr. R.G. Shetkar,
PES College
spoke about preparation and characterization of nanosize manganite perovskites.
Technical
Session-II
The second
technical session began after lunch. The chairman for this session was Dr. A.S Dinge.
The session began with a presentation by Prof. Lalit Kukreja,
Raja
Ramana
Center
for Advanced Technology,
Indore
on recent advances in nanomaterials for electronic industry. He described the changes
in behavior of materials like zinc oxide when there is diminishment of size and
explained that band gap, oscillator strength and absorption coefficient are modified
at nanometer level. He also explained the function of semiconductor quantum well
and dot lasers.
Dr. R.B.
Tangsali,
Goa University
spoke on the topic “Exploration in Nanomagnetism”. He explained that a fundamental
understanding of nanomagnetism can be exploited to yield integrated systems and
presented various observations. He was confident that nanotechnology would yield
better diagnostic tools.
The second
part of session II began after tea break. The chairman for this session was Dr.
Arun V. Salker.
Dr. N.N..Ghosh,
gave a presentation on “Novel synthetic strategies and characterization of nanomaterials”.
He explained the strategies to prepare nanomaterials and spoke about the major challenges
faced in their preparation like cost and precise chemical composition. The objectives
he said are the development of chemical methodologies. He explained how he and his
team have developed nanoferrites and meso porous silica.
This
was followed by the paper presentation by Mr Atmaram V. Gaonker,Govt. Polytecnic,
Bicholim whose topic was “Nano electronic devices-opportunity and challeges”. Ms.
Puzy A. Pavaskar, Ration Pharma, Verna spoke on Synthesis and characterization of
nano size tetra amino metal phthalocyanine. Mr. Bhanudas D. Naik, BITS-Goa, spoke
about development of a modified hydrothermal technique for systhesis of nanostructured
mesoporous silicate based materials.
