Title: Nanotheranostic lipoprotein-inspired zinc oxide-bound paclitaxel for enhanced anticancer photochemotherapy
Time : 14:45- 15:15
Biography:
Yaw Opoku Damoah has completed his BSc from the University of Cape Coast, Ghana. He is a Graduate of the China Pharmaceutical University where he has pursued Postgraduate studies in Pharmaceutics. As part of his national service, he has worked with the Import and Export Control Department of the Food and Drugs Authority, Ghana. His research is focused on nanotechnology, drug delivery and theranostics. He is specifically interested in the use of nano-theranostics for site-specific delivery and diagnosis. He is currently a PhD (Pharmaceutics) candidate at the Australian Institute for Bioengineering and Nanotechnology, The University of Queensland, Brisbance, Queensland, Australia.
Abstract:
With the emergence of nanotechnology, there is a pressing need for novel bio-friendly drug delivery systems which are capable of eliminating all the constraints related to traditional treatment regimens. Driven by this need, this work encompasses drug targeting via reconstituted High-Density Lipoproteins (rHDL), chemotherapy, photodynamic therapy and in vitro nano-inspired theranostics. Herein, we successfully fabricated zinc oxide-bound paclitaxel (ZnO/PTX) and packaged the photo-chemotherapeutic formulation into rHDLs via one-pot synthesis. The final rHDL mediated ZnO/PTX nanomedicine (rHDL/ZnO/PTX) shared a characteristic near-spherical shape and FTIR analysis proved that ZnO was successfully bound to PTX via hydrogen bonding. The PTX and ZnO drug release pattern was analyzed by HPLC and ICP-OES analysis, respectively. The results suggested that ZnO could remain intact in neutral medium but could gradually dissolve in acidic media to trigger the collapse of the nanoparticle. The in vitro antitumor efficacy on A549 cells was evaluated by MTT assay and flow cytometry. The final nanoparticle irradiated with UV light proved to be the most efficient treatment group. This was further confirmed by the quantitative and qualitative detection of Reactive Oxygen Species (ROS) which indicates the apoptotic ability. Confocal laser scanning microscopy was used to detect the presence of ROS and the resulting images suggested that rHDL/ZnO/PTX could produce significant quantities of ROS. Flow cytometry analysis was employed to confirm that the fluorescence was more conspicuous in cells that were irradiated with UV light as compared to those without UV irradiation. We further employed flow cytometry to evaluate the existence of apoptotic and necrotic cells after a period of treatment. Moreover, ZnO fluorescence was adapted to track intracellular trafficking, suggesting that rHDL/ZnO/PTX could be harnessed for UV light-mediated photo-chemotherapy while apolipoprotein A-I (apoA-I) could help facilitate the shuttling of drugs into cancer cells via SR-BI receptors. In addition, we demonstrated that ZnO could be used as a potential in vitro theranostic moiety which could mediate photodynamic therapy and pH-responsive drug delivery.

Title: Substrate and annealing temperature effects on GaAs PN junction solar cells
Time : 15:15 - 15:45
Biography:
Yahia Fayiz Makableh has completed his PhD degree in Electrical Engineering from the University of Arkansas in 2015. Currently he is an Assistant Professor and the Supervisor of the central labs in the Institute of Nanotechnology at Jordan University of Science and Technology. His research is focused on investigating nobel optical nanomaterials for high efficiency solar cells and energy harvesting. He also works on self-cleaning surfaces and light weight and high strength nanocomposites. He has published several papers in the field of solar cells and optical nanomaterials.
Abstract:
High efficiency solar cells are of a wide interest worldwide due to the higher demand on renewable energy resources. Optimizing the design and fabrication of any type of solar cells is a vital process to minimize any loses due to fabrication limitations and errors. In this work the effect of the optimization of the annealing process was studied. Two scenarios were experimentally investigated in the first scenario the substrate temperature was help at elevated temperature than room temperature without post annealing. In the second scenario a post annealing process was performed by using RTA technique. As a result, the substrate heating during metal contact deposition by using E-beam evaporation enhanced single junction GaAs solar cells power conversion efficiency by up to 25% compared to the case of post annealing. This result is obtained by the J-V characterization of different single junction GaAs solar cells for both annealing processes.

Shree Laxmi Prashant has her expertise in the fields of concrete technology. She has a passion in trying out new and innovative methods of designing the concrete to optimize the performance of concrete. She has been working on High Volume flyash concrete, Geopolymer concrete and use of industrial, plastic and C&D waste as filler materials for concrete. Presently guiding one Phd Student (under QIP scheme), one Mtech and 6 Btech students for their project on the theme of Sustainable development in concrete using various non biodegradable waste including ewaste. Developing geopolymer concrete in order to minimize the use of cement in concrete to reduce the carbon foot print. The paper entitled “Effect of partial replacement of coarse aggregates by E waste on strength properties of Concrete” has been awarded as Best Technical paper at International Conference on Sustainable construction and building materials at NITK Surathkal June 18-22 2018.
Abstract:
Microstructure plays a vital role in defining the strength and durability performance of concrete. The study of mechanism taking place at a nanoscale especially the hydrated cement paste helps to engineer the concrete in a well-defined and systematic way. This helps in improving the microstructural properties of concrete in the interfacial transitional zone. Nanoparticles also densify the concrete by occupying the spaces between the cement particles. This reduces the porosity of the cement paste. Nanoparticles are usually added in small amounts about 1-2% of the cement content in concrete. The shape and amount of nanoparticles can be tailored in order to optimize the performance of concrete to suit various projects. This paper reports the state of the art in use of nanoparticles in concrete.
