Keynote: Superior thermoplastics prepared entirely from lipids: synthesis, structure and properties
Time : 09:05-09:30
Biography:
Suresh Narine, named in 2011 as one of Canada’s Top 40 Under 40 Leaders, is Professor of Physics and Astronomy and Chemistry at Trent University; he also is the Natural Sciences and Engineering Research Council of Canada Industrial Research Chair in Lipid Derived Biomaterials, the Ontario Research Chair in Green Chemistry and Engineering and the Director of the Trent Centre for Biomaterials Research. His work focuses on the creation of petrochemical replacements for pharmaceuticals, lubricants, polymers, adhesives, and high-value materials from vegetable oils. He is the author of nearly 200 peer reviewed publications and more than 60 patents.
Abstract:
Functional thermoplastics are much sought after because of their reprocessibility and wide applicability. They are used in a wide variety of applications ranging from automotive parts and building construction to footwear, wire and cable insulation jackets, biomedical devices, etc. Polyesters, polyesteramides and polyesterurethanes present a versatile combination of chemical and physical properties such as biodegradability, flexibility, resistance to dilute acids and alkalis, thermal stability and mechanical strength. There is a desire to utilize renewable feedstock such as vegetable oils to synthesize these materials and therefore reduce their carbon footprint. This talk will detail a careful structure-function approach to the optimization of monomeric structure, polymerization protocol and polymer structure so as to produce lipid-based thermoplastics which are equivalent to or even more functional than current thermoplastics used in the industry. The talk will focus on the synthesis of the monomers, the variation of polymerization protocol, and the relationship of structure to mechanical, thermal and degradation properties.

Keynote: Developing environment-sensitive molecular probes for target binding-activated fluorescence imaging
Time : 09:30-09:55
Biography:
Yi Pang received his PhD in 1990 from Iowa State University, USA. He was a Post-doctoral fellow at US DOE Ames Laboratory during 1991-1993. He is currently a Professor at The University of Akron. He has published more than 135 research papers in reputed journals. His current research interests include synthesis of luminescent polymers, and development of fluorescent molecular probes for recognition of biologically important species.
Abstract:
Recognition of specific biomolecules such as a unique proteins in biological cells is critical for basic biomedical research and the development of novel clinical diagnostics. Considerable interests exist in searching for the novel fluorescent probes that can target specific biological tissues/molecules to meet the need for advanced bioimaging. For in vivo tracking of a specific type of biomolecule or tissue, the probes are also required to be non-toxic, and their presence should not disturb the normal biological development process. In the presentation, we discuss a new class of fluorescent imaging dyes, which are typically non-fluorescent in an aqueous environment. The probes, however become highly fluorescent upon binding to biomolecules such as proteins. The binding-activated fluorescence on biomolecules can be further developed to give wash-free imaging reagents, as those free probes are nearly non-fluorescent in the surrounding aqueous environments. Further extending this concept has led to advanced imaging reagents, which selectively targets the biomolecules in the subunits of biological cells, e.g. organelles, to give fluorescence turn on.

Abstract:
Based on laboratory based growth of plant-like structures from inorganic materials, we present new theory for the emergence of plant structures at a range of scales dictated by levels of ionization (charge density), which can be traced directly back to proteins transcribed from genetic code and their interaction with external sources of charge (such as CO2) in real plants. Beyond a critical percolation threshold, individual charge induced quantum potentials (driven by dissipative systems) merge to form a complex, interconnected geometric web, creating macroscopic quantum potentials, which lead to the emergence of macroscopic quantum processes. The assembly of molecules into larger, ordered structures operates within these charge-induced coherent bosonic fields, acting as a structuring force in competition with exterior potentials. Within these processes many of the phenomena associated with standard quantum theory are recovered, including quantization, non-dissipation, self-organization, confinement, structuration conditioned by the environment, environmental fluctuations leading to macroscopic quantum decoherence and evolutionary time described by a time dependent Schrödinger-like equation, which describes models of bifurcation and duplication. Evidence for macroscopic quantum phenomena has previously been reported in photosynthetic systems [2,3] The theory and evidence presented in the current work suggests that macroscopic quantum systems are not an exception in plant systems, but actually play a key role in the emergence of structure. Based on these insights we consider how the fundamental principles

Abstract:
Solvent free conversion of canola oil and fatty acid methyl esters (FAME's) derived from canola oil and waste cooking oil under microwave irradiation demonstrated dramatically enhanced rates. The microwave-assisted reactions lead to the most valuable terminal olefins with enhanced yields, purities and dramatic shortening of reaction times. Various monomers/chemicals were prepared in high yield in very short time. The complete conversions were observed at temperatures as low as 50 ºC within less than five minutes. The products were characterized by GC-MS, GC-FID and NMR. The prepared monomers were converted into biopolymers and characterized in detail using NMR, FTIR, DSC, TGA, DMA and mechanical testing techniques. In another approach, amphiphilic ABA type PEG-Lipid conjugated macromolecules have been synthesized using the copper-catalyzed azide-alkyne cycloaddition commonly termed as “click chemistry. Characterization of the conjugates has been carried out with the help of 1H-NMR, FTIR and GPC. The conjugates were evaluated for the encapsulation and release of an anticonvulsant drug (carbamazepine) as a hydrophobic drug model in the study. The micellization, drug encapsulation and release behavior of macromolecules was investigated by dynamic light scattering (DLS), transmission electron microscope (TEM) and fluorescence spectroscopy. From the results, it has been concluded that the nanoparticles had different average sizes due to different ratio of hydrophilic contents in the conjugate backbone. The Amphiphilic particle size and structure could be altered by changing the ratio of hydrophilic and hydrophobic contents. The in vitro drug encapsulations highlighted that all the drug-loaded micelles had spherical or near-spherical morphology. In vitro drug release study showed the controlled release of hydrophobic drug over a period of 50 hours. The results indicate that there is great potential of renewable lipid-based micelle nanoparticles to be used as hydrophobic drug carriers.

Abstract:
INTRODUCTION
In 2050 very probably 9 billon people will live on earth, resulting in significant challenges. Major tasks will be supply of food, the more efficient use of resources (raw materials, energy), protecting the environment and prevention of further climate changes.
RENEWABLE RAW MATERIALS AND MONOMERS
Use of renewable raw materials for monomer production offers the opportunity to improve sustainability, esp. the carbon footprint. Important renewable monomers are lactic acid (for PLA), 1,4-butanediol, succinic acid, mid chain dicarboxylic acids (for biodegradable polyesters), 1,3-propanediol (for PTT) and furandicarboxylic acid (for PEF). Actually only 1st generation biorefineries (e.g. corn to glucose) are in place while 2nd generation biorefineries (cellulose to glucose, xylose) are still in infant status. Technological progress has been significant in the last years, but cost competitiveness to the fossil counterparts is difficult to achieve. 1,3-propanediol and succinic acid are examples where the biobased variants seem to be superior in costs and sustainability.
POLYMERS & COMPOUNDS
ecoflex® F, the aliphatic-aromatic BASF polyester, is made from terephthalic acid, butanediol and adipic acid. ecoflex® is the preferred blend partner for biobased and biodegradable polymers which typically do not exhibit good mechanics and processability for film applications by themselves (e.g. starch, PLA). The BASF brand name for compounds of ecoflex® with PLA is ecovio®.[1] The exchange of monomers (e.g. by succinic acid) gives access to polyesters and compounds with new properties.
ORGANIC WASTE MANAGEMENT AND AGRICULTURE AS APPLICATION EXAMPLES
Organic waste management and mulch film in agriculture are two application examples where biodegradable and renewable polymers add value. Approximately 40% of the household waste is organic waste, which can be converted to energy and to valuable compost. To enable this organic recycling, biodegradable organic waste bags and coffee capsules have been developed. Mulch film offers the opportunity to increase crop yield by reducing water consumption, improving microclimate and preventing growth of weeds. Biodegradable mulch film is plowed in the soil after harvest thus reducing the number of working steps.
END OF LIFE AND SUSTAINABILITY
The prerequisite for these applications is the biodegradability of the used polymer compounds. Polymer biodegradation commonly begins with the (hydrolytic) breakdown of the main chain – often enzymatically catalyzed – followed by mineralization of the resulting small molecules by microorganisms present in the respective habitat. Therefore elucidation of the interaction of microorganisms and their respective enzymes with polymer substrates in different environments and deducing relevant structure-property relationships is an important task of BASF biopolymer research.
CONCLUSION
Biodegradable and renewable polymers will not resolve the worlds sustainability challenges. But, smartly used, they will contribute to its solution.

Abstract:
The main achievements of science and technology in the last century have brought substantial improvements in the quality of life of the human species (i.e., in food production, health, energy, transport and communications). However, new approaches and a change in paradigms are urgently needed to address remaining gaps in health worldwide. Some of these include: 1) Strategies to fight microbial drug resitance; 2) novel and more effective therapies against cancer; 3) effective therapies against neurological disorders related to aging. The modern understanding of health is based on the concept of regulation of metabolism by a complex network of communication mechanisms based on signaling molecules that regulate basic cellular activities and coordinates cell responses so they can act in concert. These respond to, are controlled by, and can be interrupted by processes occurring in at the molecular and supramolecular/macromolecular scales. The latter are the domain of bioinspired nanomaterials. These biomaterials are believed to be key in the development of new approaches to tackle the disease. A fundamental reason in this respect, is that these materials not only share similar building blocks, but also the hierarchical organization in the length scale of living systems, for example, bones, shells, hair, fibers, etc. This conference will address recent advances in our laboratory with the aim of contributing to some of the health challenges. To do this, we have to use platforms based on nanomaterials based on biopolymers. These include nanoparticles and nanocapsules capable of disrupting quorum sensing in Gram negative bacteria; nanocapsules capable of preventing the adhesion of Helicobacger pylori to stomach cells; electrostatically self-assembled nanocomplexes of chitosan and polynucleotides (pDNA, siRNA and microRNA) able to transfect cells of breast cancer and cystic fibrosis cells; and nanocapsules loaded with capsaicin that can reversibly disrupt the tight junctions and therefore permeabilize drugs across epithelial cell monolayers. In vitro proof-of-concept of the effectiveness of these systems will be discussed. The current obstacles and future perspectives will also be discussed in the context of the translation of these nanomedicine to the clinic.

Abstract:
Textile mill, the largest revenue earning industry in Bangladesh is facing problem with the disposal of its solid waste (sludge). In this study, textile sludge is detoxified with gamma irradiation (15 kGy) and then used to make environmental friendly bricks for construction purposes. Bricks were graded based on the sludge and clay content ratio. Sludge was mixed with clay and bricks were made in wooden frame. Dried brick samples were then kept at 450°C for 24 hours in furnace. Controlling the temperature allowed us to produce the brick without producing any NOx. Parameters such as density (g/cm³), weight loss (%), firing shrinkage (%), BS (MPa), BM (MPa), IS (kJ/m²), water uptake (%) and electrical resistivity (Ω-m) were investigated. Density, weight loss, firing shrinkage, electrical resistivity reduced as sludge content (%) in bricks increased whereas BS, BM, IS and water uptake (%) increased with the increase of sludge content. The optimum results were found for the 50-50% sludge/clay samples. Further increasing of the sludge percentages led to loss of strength and compactness of the brick sample. According to the results, the optimum sample showed higher strength than the sample made by pure clay but showed slightly lower strength than the commercial brick. The change of density of all bricks was experienced during the ageing tests in water, acid, alkali and salt. BS, BM, IS also tested for water and acid ageing. Morphological analysis of the brick samples were done by metallurgical inverted microscope.
