Abstract:
Nanomaterials have been widely tested in vitro and in small order animal studies for decades. Results have shown greater tissue growth, decreased bacteria growth and inhibited inflammation. However, few studies exist examining human tissue response to nanomaterials. This presentation presents a cohort study of nano implants inserted into humans. In particular, one study includes the implantation of nanotextured spinal implants into over 14,000 patients over the past 5 years. Results demonstrated no cases of infections or other implant failures which is significantly better than statistics on conventional spinal implants which have up to 20% failure rates. This study will further explain that nano implants mimic the natural nano texture of bone
itself and possess surface energy that can competitively increase the adsorption of proteins known to promote osteoblast (bone forming cells) functions, decrease bacteria functions and limit inflammatory cell functions. As such, this presentation will cover the few human clinical studies on nano implants showing improved human health.

Abstract:
Nanotechnology became a widespread technology in recent years in several medical and pharmaceutical applications. The major goals in designing nanoparticles as a delivery system include enhancing bioavailability by enhancing solubility and dissolution rate, targeting the drug to specific organs and controlling drug release rate. Quality by Design (QbD) encourages the pharmaceutical industry to use risk management and science-based manufacturing principles to gain process and product understanding and thus assures quality of the product. The lecture will discuss the application of QbD approach in the pharmaceutical nanotechnology. Response surface methodology using computer based factorial design to study the effect of critical factors on various quality attributes of APG nanoparticles will be discussed. Based on the optimization procedures, risk assessment and using prior knowledge and experience will be focused to define the criticality of factors based on their impact by Ishikawa fishbone diagram and Preliminary Hazard Analysis (PHA) tool.

Title: Coupled exciton- surface plasmon polariton enhanced photoresponse of 2D hydrogenated SiB
Biography:
Farzaneh Shayeganfar supervises the experimental and computational design of emerging materials research group is a part of the Department of Physics at Polytechnic. Her goal is to better design high quality functional materials by mapping the relationship between materials structures and their physical and chemical properties through a combined theoretical and experimental approach. Her group integrates all the aspects of materials research from developing the fundamental understanding to the design, synthesis and testing of new bulk and nanomaterials. They combine computational approaches in quantum mechanics, solid-state physics and statistical mechanics, with selected experiments into a
complimentary research strategy to investigate materials in the energy field.
Abstract:
Exciton (strong electron-hole interactions) and Hot Carriers (HC) created by surface Plasmon polaritons enhance the photo response of nano-electronic and optoelectronic devices. In the current research, we developed a quantum framework to study coupled exciton-HCs effects on the photovoltaic energy distribution, scattering process, polarizability and light emission of 2D-semicnductors. We show that the strain and thermal effect on the Two-Dimensional (2D) semiconductors can lead to valley polarized plasmon Quasi Particles (QP) and HC generation. Our results reveal that the electron-phonon (e-ph) and electron-electron (e-e) interactions characterize the correlation between the decay rates, scattering of excitons and generation of HCs in 2D semiconductors. Moreover, phonon assisted luminescence spectra indicate that light emission can be enhanced by increasing strain and temperature. Here, we introduce a promising stable 2D H-SiB semiconductor with engineering the elastic strain, creating a broad range of absorption spectrum (solar light capture), which concentrates plasmon resonances and polarized plasmon QP, constituting strong coupling of electronic and photonics states, which makes it as a promising candidate for light harvesting, plasmonic photocurrent devices
and quantum information.
Siddhartha S. Mukhopadhyay
Punjab Agricultural University, India
Title: Nanomaterials for agriculture
Biography:
Siddhartha S. Mukhopadhyay is Formerly Director, Electron Microscopy & Nano-science Lab, PhD Department of Soil Science, Punjab Agricultural University, Ludhiana 141004, India.
Abstract:
Agriculture works in open system, where control and fate of applied nano-materials are uncertain. This calls for redefining nanotechnology and enforcement of rigorous ethics at all stages from fabrication to application of nanomaterial in agriculture. The virtue of clean eco-system free from lethal biotic and abiotic substances and sanitation, interdependence of life forms and safety of food are the lessons we relearnt during COVID pandemic. They are especially indispensable in pedosphere-biosphere-atmosphere domains. Author
primarily focused on fertilizers because fertilizer resources are depleting at a fast pace, their low use efficiency is detrimental to environment and conventional fertilizers are made up of salts; one component of which is plantnutrient ion(s), while counter component is either not very useful or, toxic leading to irretrievable impairment to soils and food-quality threating human and animal health. Some fertilizers like phosphates contain high amounts of heavy metals (e.g., Cd, Cr, Pb, Sb, V, Zn and Cu) and radioactive elements (e.g., U and Th) and as a consequence they get accumulated in soils causing irreversible damage to the ecosystems. Author attempted to address the above stated issues by: (1) obtaining heavy metal and radionucleotide free phosphate minerals through novel beneficiation process of low-grade rock phosphate, (2) assembling exclusive phosphate ion (PO43−) and Zn2+ ions in clay mineral receptacles and (3) innovate farmer-centric method for fabricating plant nutrient supplier nanomaterials. Segregation of P-containing minerals devoid of toxic materials from Phosphate Rock (PR) ore was based on a set of physical non-destructive process that involved physical breakdown of large rock materials into smaller (sand size) parts accompanied by screening, followed by sink-or-float separation of heavy-metal free phosphorus-minerals from the sand size ore using desired specific gravity liquid that do not dissolve ore-materials. Phosphate ion was extracted by dissolving P-minerals by rhizospheric acids. Novel nanophosphorous products were manufactured by intercalating phosphate ion (PO43−) in kaolin clay mineral and novel nano-Zn in montmorillonite. The nanoproducts, when applied to soil would release either phosphate ions (PO43−), or get converted to hydrogen phosphate ions (HPO42−) or dihydrogen phosphate ions (H2PO4−) or Zn2+ ions as the case may be. Fields of agriculture consume inputs like fertilizer in huge quantities and in repetitive manner in every growing season. Novel nanomaterials might open up gigantic market opportunity.
