On the Conference Title:

“EMERGING TRENDS IN CHEMICAL SCIENCES”

A study of the science subjects cannot be complete without the subject of Chemistry;
Chemistry being an integral part of the totality of science, how the chemistry has now
become a subject which has interdisciplinary role and requires multidisciplinary outlook is
borne out by referring to the subject matter as “Chemical Sciences”.

Chemistry conventionally had three branches, organic, inorganic and physical
chemistry. However, the developments in the respective branches have made the border lines
so diffuse that contiguity of the different branches became predominant than the constraints
restoring the study to a specific branch. The interdisciplinary role enabled the chemist to
transcend into the other science subjects (let alone the transgressing the borders across to
other branches of chemistry) while the multidisciplinary nature enabled the subject of
chemistry prevail on the fields of other science subjects.

Organic chemistry may be the broad category of the study of carbon compounds
(structure, synthesis, mechanisms of reactions, characterization of the compounds, natural
products - isolation, characterisation and total synthesis). Inorganic chemistry may be the
chemistry of other elements in the periodic table (structure, synthesis, characterisation,
reaction mechanisms, properties of ores and extractions from ores). Physical chemistry may
be the state of matter in which the compounds occur, their specification of properties in
standard thermodynamic state, with reference to the standard state defining thermodynamic
and electrochemical quantities, setting equations to follow the kinetics of reactions and
enabling the physical properties be understood from the point of view of intermolecular and
intra molecular interactions.

All the efforts in studying chemistry is to find the applications to turn living more
conducive when the environment is unfavourable and to enable more congenial atmosphere
for the biological processes when affected by ill health and disease. When there are viable
applications it must be under monitored and controlled quantification and quality controlled
industrial production. Such regulatory processes call for appropriate specialisation in
Analytical chemistry and Industrial chemistry. Pharmacology and drug designs add to the
widening of the area of chemical research. Thus the conventional branches have acquired
interdisciplinary nature.

The multidisciplinary characteristics can be well justified by the emerging trends in
chemical sciences. The developments indicated in the previous paragraph call for the
awareness on the emerging trends in chemical sciences. Thus this awareness is to be
emphasized is the need of the hour for the Chemistry to be even better contributing for the
living standards. The topic of the International Conference has been aptly identified for the
“knowledgeable laymen” to know the rapid pace in which the Chemical sciences is taking
strides to ameliorate the consequences of environmental degradation while positively
contributing to health and prosperity due to the human endeavours, one of them being the
scientific research activity. To know more about the variety of names for chemical research
area emanating currently, it may be worth the while glancing through the following pages of
this booklet.

As there is progress and growth, Conferences on Emerging trends would be an avenue
for the evaluation of the benefits of scientific research and assessment of the educational system.

The textual matter above has been written by Prof. S. Aravamudhan, Delegate; ICETCS2013

4. Vice Chancellor, CUG, and
5. Dean, School of Chemical Sciences, CUG.

The messages (as in pages from 5 to 9) expressed happiness that this international
conference is being organized by the Central University of Gujarat. The information about
the ICETCS2013 has been received with much delight as it would catalyze exchange of ideas
among the talents of the country. As Science and scientific research play an important role in
the development of the nation the organizing of ICETCS2013 at CUG has brought immense
pleasure to people at helm of affairs on educational matters. The University authorities were
glad that School of Chemical Sciences is organizing the ICETCS2013 at CUG. That the
organizers extended warm welcome to the delegates is indicative of the enthusiasm and
expectations of significant outcome from the deliberations.

The international conference proceedings were held at such convenient pace and
congenial atmosphere is itself endorsing the good wishes of one and all for the smooth
conduct of the event. The remaining part of this booklet should convince that the objectives
have been accomplished to such an extent that this first International event would pave the
way for further events of similar nature for improving the standards of education, and
facilitate research and teaching more intensely and effectively.

Comments on the Proceedings/ Souvenir contents

The invited talks were delivered by eminent chemists who are experts in their
respective area of chemical research. There were 23 invited talks and the contents covered a
wide area of the Chemical Sciences and to name a few, the following is a list:

1) Chemical publications, 2) Chemical technology, 3) Green Chemistry, 4)
Computational Chemistry, 5) Nano Chemistry, 6) Thin films chemistry and 7) Medicinal
chemistry.

As explained in an earlier context, that chemical sciences indicate the interdisciplinary
approach and multidisciplinary trends in chemical applications is borne out by the highlights
of the contents of invited talks as summarised in pages 14, 15 & 16 of this booklet.

In addition to the 23 invited talks, there were 47 oral presentations and 56 Poster
Presentations. For a two day – event, this many number of contributions all together only
demonstrates the overwhelming enthusiasm (an encouraging feature for holding such
conferences in the coming years as well) for the participation and as pointed out while
enumerating the Invited talk highlights, the subject matter that was covered during the entire
proceedings, projected out the emerging trends in chemical sciences; and the conventional
Synthesis and characterisation aspect (detailed chemical aspects dealt with in the oral and
poster presentations) played the vital role as required for the applications to get the limelight.
Even while almost every contributor had a synthesis and characterisation elements in their
work, its role was not dominatingly conspicuous but it was gratifying to find the necessary
support to enable the applications be highlighted convincingly. And, for such a task,
naturally, it is no wonder that there was time constraint! The Chairpersons of the technical
sessions and the Organizers of the event had to face an uphill task to make both ends meet:
the need for more and more time required to cope up with getting the insight on the emerging
trends at one end, and at the other end, the time-constraint that was inevitable to make the
participant’s stay pleasant and participation in the Conference proceedings meaningful;
further the dispersal to their respective places on time with fond memories of the event.

The Best Oral & Poster Presentation awards was intended to enthuse the aspirant
young scientists and research scholars to take part in such scientific events, and to be part of
such gatherings by contributions. A complete list of names of invited speakers, oral and
poster presenters is included in the pages 11 & 12 of this booklet with the corresponding
event code numbers assigned during the Conference. These are available in the Souvenir
given to all the participants as part of Registration materials. Further details of their
presentation and contact information can be obtained on writing to the organizers, in
particular addressing to Prof. Man Singh, Dean, School of Chemical Sciences, Central

Invited Talks and Contributions at ICETCS2013

The invited talks were delivered by eminent chemists who are experts in their respective area of
chemical research. There were 23 invited talks and the contents covered a wide area of the Chemical
Sciences

Highlights from the Invited Talks

Chemical Publications:
The Journal of Scientific and Industrial Research (JSIR) stared in 1942 and is a monthly journal. It
serves as an information link between generators and users of technologies and address to
entrepreneurs, technologists, engineers, technocrats and scientists on one hand, and planners,
administrators and managers on the other.

Chemical Technology:
Short movies displayed enabled better insight into the changes which the crystals undergo during
guest sorption/desorption processes or change of sorption equilibrium in the systems solid-solution.
Examples of practical uses of sorption selectivity in chromatographic applications of chiral separations
were given.
Addition of surfactants leads to an increase in relative viscosity of polymers after certain
concentration of the surfactants. Further increase in relative viscosity is significant in case of Geminis
and this increase is ascribed to the physical cross-linking of surfactant micelles with NaCMC chains.
Pseudo phase kinetic models (originally developed for interpreting chemical reactivity in
homogeneous association colloids such as micelles, micro emulsions, and vesicles) were shown also
to be applicable to phenomena in fluid, stirred, opaque oil-in-water emulsions. The results show that
phenolic AOs, are located primarily in the interfacial region of the emulsions, except at low surfactant
concentrations, and that their distributions depend on both surfactant concentration and oil polarity.
Laboratory experiment coupled with commercial trials confirmed the high intensity focused
ultrasound (HIFU) to be beneficial for process control and significant energy saving during sugar
manufacturing.
There are inherent difficulties in the synthesis of these compounds, such as oligo- and poly-
merization, air sensitivity, and use of toxic, obnoxious and malodorous compounds. The synthesis of
many cyclic phosphines such as four- membered phosphetane, five-membered phospholane, six-
membered phosphorinane and seven-membered phosphepane using Fe(II) as a suitable template
will be demonstrated, in addition to the synthesis of a rare example of tetrahedral P4 cage on a Cu(I)
template.
The kinetics of micellar-catalyzed oxidation of dextrose and mannose by N-bromophthalimide was
studied in the presence of sulfuric acid at 40°C. The order of reaction with respect to [substrate],
[oxidant] and [H+] were found to be fractional, first and negative fractional order, respectively.
Anionic micelles of sodium dodecyl sulphate showed a partial inhibitory effect while cationic micelles
of cetyltrimethylammonium bromide increased the reaction rate with the same kinetic behavior.
Oxidative functionalization of alkenes by an intermolecular sulfinyl nucleophile as the key step in the
synthesis of (-)-tetrahydrolipstatin (THL), analogues of mannostatin A and toward a synthesis of
tetrahydroxy long chain base (LCB)
The processes of dissociation of multiply charged molecules play important role in our planetary
atmosphere and interstellar space. Such processes can be studied in greater detail by employing an
ion momentum imaging spectrometer (IMIS). The absolute partial ionization cross sections of CO2
molecule are reported for impact of 10-26 keV electrons as well as the complete and incomplete
Coulomb explosion pathways for CO22+ and CO23+ ions were identified and discussed.

Green chemistry:
Recently Green Chemistry Experiment designed by us is published in ACS Journal of Chemical
Education and ACS cited this as most read experiment. The Academic Community has to adopt Green
Chemistry and Green Chemical Technology and their philosophy to be infused in Education and
Research. The chemists of the future have to grow up in an environment where the Principles of
Green Chemistry will be the tools for the design of their research.

15 | P a g e

The concept of green chemistry has encouraged organic chemists to include water as a solvent.
Incredible selectivity’s and activities can be achieved through the addition of surfactants with a
defined nano sized micellar structure. . Cross aldol condensation carried out in micellar media is
observed to be faster and selective than that in the aqueous solution.
Green chemistry protects the environment, not by cleaning it up but by inventing new chemistry and
new chemical processes that do not pollute. This objective can be achieved through the development
using green chemistry techniques like microwave heating, supercritical carbon dioxide as an
important commercial, industrial green solvent, ionic liquid, Sono chemistry, aqueous hydrogen
peroxide for clean oxidation, super critical water oxidation, biocatalyst in chemical synthesis, biofuel,
hydrogen fuel etc.
A technique has been developed for bioremediation of phenol which is generally found in
petrochemical waste.
This has proved the versatility of potential microorganisms Pseudomonas putida IFO 1471 for
bioremediation of phenol. The identified gene responsible for phenol degradation will be a beneficial
source for biodegradation of hazardous compounds.
The positive side of nanoparticle pesticides is that far less needs to be applied and according to the
supporters of nano-technology, this reduces costs and environmental damage. Development of
topical formulations containing repellents and residual insecticides impregnated in fabrics has been a
great advance in prevention of insect bites.
The aim of this study was to develop nanoparticles containing insect repellent/control active
ingredients and to evaluate the incorporation and the permanence of them in different fabrics after
several washes.

Computational chemistry:
Computational chemistry offers a wide choice of menu for chemical education and research.
Computational chemistry calculation and molecular modelling provide reliable and accurate
information which is almost impossible to obtain through observations from experiments. Orbital
contributions, rates and energy levels of each of the photo emissive states (1MLCT = fluorescent state
and 3MLCT= phosphorescent state) of a compound were identified, calculated, reliably interpreted by
the sophisticated tool –Amsterdam Density Functional (ADF) Program package (version 2000) and
finally compared with the experimental findings successfully.
There remain cases of macromolecular computations for which the use of brute force computer
simulations is clearly not the solution. For such cases the importance of small molecule computational
chemistry related to macromolecular computations should be emphasized. Trying to get results with
minimum expense at the learning stage, at the same time setting an awareness of the bio molecules
and the biological pathways enables a comprehension of the subject matter as to why a certain
elementary level learning is important. This provides a new level of confidence and interest in what
the beginners do and enables them to pursue the studies. This educational pattern was highlighted
with illustrations from the earlier results of this author.

Nano chemistry & nanoparticles:
The palladium (II) complexes catalyse Suzuki-Miyaura coupling reactions under mild conditions via
the formation of nanoparticles composed of palladium and selenium. The length of alkyl chain present
on the Se unprecedentedly controls the dispersion and composition of these particles and
consequently the catalytic activity.
Present study revealed that α-alumina nanoparticles can serve as an efficient adsorbents for the
removal of Ni(II) and Cr(VI). These data can be used in the design of a treatment plant at industrial
scale.
Synthesized polyhydrazide derivative of few calix-systems have been used as reducing and stabilizing
agent to yield stable gold and silver nanoparticles in a single pot in few minutes (instantaneously).
Synthesised nanoparticles have been found to be stable at ambient temperature over wide range of
pH and have been characterized by UV-Vis spectroscopy, transmission electron microscopy (TEM) and
particle size analyser (PSA). Due to their unique optical properties the emergence of nanomaterial
based sensor is currently considered a rising hope for designing smart sensors, which not only have
the potential to recognize analytes in real-time, but can also perform their detection with extremely
high sensitivity and selectivity. Therefore these well characterized stable multifunctional nanoparticles
which find applications as sensors for various analytes will be discussed during the lecture.

Thin films:
Spray pyrolysis is a very simple cost effective technique for large area deposition of Semiconductor
thin films with good reproducibility. We have deposited CdS thin films on glass substrate by chemical
spray pyrolysis.
Some interesting results on the physical properties were presented in detail.
It was found that ZnO thin film annealed at 200°C has high degree of crystallographic imperfection.
Surface morphology of the films has been analysed by scanning electron microscopy (SEM). Photo
luminescent spectrum at room temperature studied.

Medicinal Chemistry:
The chitosan based delivery systems found to be highly efficient in their loading and release
behaviour of an active agent in comparison to delivery systems based on synthetic polymers. The
property of chitosan delivery systems has been tuned further adding different ionic species during
their fabrication to control response of the delivery systems with the physiological conditions.
Chitosan with different degree of deacetylation have been produced and used to analyse the effect of
degree of deacetylation on the release behaviour of the delivery systems for the drugs used in the
contraception and in the treatment of the tuberculosis.

On Contributed Presentations:

In addition to the 23 invited talks, there were 47 oral presentations and 56 Poster Presentations. For
a two day – event, this many number of contributions all together only demonstrates the
overwhelming enthusiasm (an encouraging feature for holding such conferences in the coming years
as well) for the participation and as pointed out while enumerating the Invited talk highlights, the
subject matter that was covered during the entire proceedings, projected out the emerging trends in
chemical sciences; and the conventional Synthesis and characterisation aspect (detailed chemical
aspects dealt with in the oral and poster presentations) played the vital role as required for the
applications to get the limelight. Even while almost every contributor had a synthesis and
characterisation elements in their work, its role was not dominatingly conspicuous but it was
gratifying to find the necessary support to enable the applications be highlighted convincingly. In fact,
the oral presentation materials had much detail to pervasively cover the subject of Material Sciences.
