  • extraction and Characterization of Nanomaterials from agrowaste
    2020
    Co-Authors: Deepu A Gopakumar, Nathalie Lyczko, Hanna J Maria, Ange Nzihou, Sabu Thomas
    Abstract:

    Green chemistry started for the search of benign methods for the development of nanoparticles from nature and their use in the field of antibacterial, antioxidant, and antitumor applications. Biowastes are eco-friendly starting materials to produce typical nanoparticles with well-defined chemical composition, size, and morphology. Cellulose, starch, chitin and chitosan are the most abundant biopolymers around the world. All are under the polysaccharides family in which cellulose is one of the important structural components of the primary cell wall of green plants. Cellulose nanoparticles can be extracted from agrowaste resources such as jute, coir, bamboo, and pineapple leaves, coir etc. Chitin is the second most abundant biopolymer after cellulose, it is a characteristic component of the cell walls of fungi, the exoskeletons of arthropods and nanoparticles of chitin can be extracted from shrimp and crab shells. Chitosan is the derivative of chitin, prepared by the removal of acetyl group from chitin. Starch nanoparticles can be extracted from tapioca and potato wastes. The preparation of these nanoparticles includes both series of chemical as well as mechanical treatments; crushing, grinding, alkali, bleaching and acid treatments. Transmission electron microscopy, scanning electron microscopy and atomic force microscopy are used to investigate the morphology of nanoscale biopolymers. Fourier transform infrared spectroscopy and X-ray diffraction are being used to study the functional group changes, crystallographic texture of nanoscale biopolymers respectively. Since large quantities of bio wastes are produced annually, further utilization of cellulose, starch and chitins as functionalized materials is very much desired. These nanoparticles can be converted into smart and functional materials by functionalization through chemical modifications due to the presence of large amount of hydroxyl group on the surface. The cellulose, starch and chitin nanoparticles are currently obtained as aqueous suspensions which are used as reinforcing additives for high performance environment-friendly bio-degradable polymer materials. These nanocomposites are being used as biomedical composites for drug/gene delivery, nano-scaffolds in tissue engineering and cosmetic orthodontics. The reinforcing effect of these nanoparticles results from the formation of a percolating network based on hydrogen bonding forces.

    Abstract:

    Abstract Optical properties are among the most entrancing and helpful properties of Nanomaterials and have been widely examined utilizing an assortment of optical spectroscopic strategies. Here, we present a detailed discussion covering the optical properties of metal nanoparticles, semiconductor nanoparticles, semiconductor quantum dots, metallic clusters, and carbon-based materials. It covers UV-Vis absorption and the photoluminescence (PL) properties, their control, and origins in various nanoparticles. Different mechanisms in which nanostructures exhibit PL are discussed. The optical-related applications of nanoparticles are explained in a detailed manner. We have critically analyzed the surface-enhanced Raman scattering and nonlinear optical limiting properties of different types of nanostructures.

  • Thermoanalytical Techniques of Nanomaterials
    Characterization of Nanomaterials, 2018
    Co-Authors: Jiji Abraham, Arif P. Mohammed, M.p. Ajith Kumar, Soney C. George, Sabu Thomas
    Abstract:

    Abstract Designing and fabrication of materials with good thermal characteristics is very important for multifunctional applications of Nanomaterials. Thermal analysis is a group of techniques that characterize the thermal properties of materials. With these techniques, changes in the temperature of the sample is analyzed. No single thermal analysis tool or technique works best in all situations. Accurate thermal assessments require a combination of different analytical techniques. This chapter presents the basic principles of thermal systems and describes some of the techniques and tools available to complete thermal Characterization of Nanomaterials.

  • thermogravimetric analysis for Characterization of Nanomaterials
    Thermal and Rheological Measurement Techniques for Nanomaterials Characterization, 2017
    Co-Authors: Sravanthi Loganathan, Ravi Babu Valapa, Raghvendra Kumar Mishra, G Pugazhenthi, Sabu Thomas
    Abstract:

    Abstract This chapter discusses the basics and principles involved in the instrumentation of thermogravimetric analysis (TGA). Different types of balances, crucibles, and furnaces used in TGA instrumentation are addressed. The basic information that can be derived from a thermogravimetry thermogram is also discussed in detail, as are advanced TGA instruments utilized for evolved gas analysis and their application in predicting the thermal decomposition mechanisms of polymer nanocomposites. Further, the application of TGA in fields such as determination of drug and functional moiety loading, gas adsorption studies, relative strength of catalysts, and thermal degradation kinetic analysis for polymer nanocomposites is addressed with appropriate case studies.

    Co-Authors: U Burghaus, Flemming Besenbacher, Zhong Lin Wang
    Abstract:

    The use of nanotechnology to develop a suite of sustainable energy production schemes is one of the most important scientific challenges of the 21st century. The challenge is to design, to synthesize, and to characterize new functional Nanomaterials with controllable sizes, shapes, and/or structures. To summarize the progress of the research and development made in this important field, the Fuel Chemistry Division of the American Chemical Society (ACS) organized a symposium on “Nanotechnology for Sustainable Energy and Fuels” during the 240th ACS National Meeting in Boston, MA on August 22−26, 2010, with the ACS Catalysis Division as the cosponsor. This symposium was a global gathering of leading scientists at the intersection of energy and nanotechnology. The topics discussed at the symposium included nanotechnology, not only for traditional fossil fuel production but also for novel processes for renewable energy applications.

    Co-Authors: Mark Anderson
    Abstract:

    The ability to perform compositional analysis for in situ elemental Characterization of Nanomaterials, both at room temperature and during heating, provides important insight to structural and compositional changes. In this use case, we demonstrate the use of NanoEx-i/v in the dynamic inter-diffusion process of Silicon through an Aluminum oxide interlayer which results in the growth of large crystalline grains of Silicon, used to design solar cells and transistors. To understand the compositional and structural changes induced by the applied heating, the Al and Si elemental live maps were acquired at every temperature.
