Synthesis and Applications of Conductive Polyaniline Rice Husk Ash Silica Nanocomposites: A Comprehensive Review | Chapter 9 | Chemistry and Biochemistry: Research Progress Vol. 4

Recently, the development of Nanotechnology, Nanoscience and Nanomaterial have received more attention following its optical, mechanical, electrical and chemical properties. Nanostructures have a prominent place in Nanotechnology since more space can be used in different applications. In the past decades, a class of conductive polymers became famous because of their mechanical and electrical properties. Polyaniline is a conductive polymer popularly known as an environmentally stable and highly adjustable polymer given in an application form of powder, membranes or loose fibres. Low-cost polyolefin and large-scale production are widely used in broad applications. Rice Husk Ash (RHA) is the by-product of the rice mill industry considered as waste material. Many types of research focused on RHA target the highly contained silicate to be converted to silica after Rice Husk (RH) pyrolysis undertaken in a furnace with a temperature of (800˚C). The sol-gel technique offered a simple route in producing silica from RHA, where 3- (chloropropyl) triethoxyscilane (CPTES) is used to convert the RHA into high-quality silica. Polyaniline/Rice Husk Ash Silica Nanocomposite (PANI/RHACCl (SiO2)NCs) are prepared via chemical oxidative polymerization and can be used in various applications such as supercapacitors, pseudocapacitors, coatings, metal absorption, chemicals, encapsulation of light-emitting organs, proton exchange membrane, diffusion membrane, devices Sensor, Nanoelectronic flexible devices, as well as drug delivery. Results have shown that PANI encapsulates SiO₂ Nanoparticles with a very powerful impact on Nanocomposite morphology.

Structural Studies of ZnO Nanostructures and Nano Powders: A Recent Approach | Chapter 6 | Newest Updates in Physical Science Research Vol. 5

 Nanostructures and nanoparticles have attracted a lot of attention from scientists because of their unique features. Zinc Oxide has piqued the curiosity of researchers because it might be utilised as a low-cost alternative to Si and GaN. Because of its piezoelectric and transparent conducting capabilities, zinc oxide is one of the most promising semiconducting materials. In the visible area, it exhibits strong electrical conductivity and optical transparency, as well as strong UV absorption. As a result, it can be used as a window and sunscreen. Sensors, transducers, biomedical devices, optoelectronic devices, solar cells, and other nanostructured ZnO applications are common. In a muffle furnace, high purity Zinc is oxidised at high temperatures, resulting in nanostructures on the surface of metallic Zinc. The high-energy ball-milling technology is used to make ZnO particles. Because of its enormous direct band gap of 3.37 eV and strong exciton binding energy at ambient temperature, ZnO is widely employed. X-Ray Diffraction and scanning electron microscopy are used to examine the structure and morphology of ZnO Nanostructures. The structure and morphology of furnace melt ZnO Nano particles are the subject of this work.

Preparation and Characterization of Nanostructures in Glasses | Chapter 9 | New Insights into Physical Science Vol. 12

 Melt quenching was used to make sodium borate and sodium-lead-germano-tellurite (SLGT) oxyfluoride glasses embedded with Er³⁺ and/or Ag. The glasses were characterised using thermal analysis, X-ray diffraction, and optical spectroscopy measurements. Heat treatment of the glasses resulted in the formation of nanoparticles. Because of the increased field in the vicinity of silver particles, Er³⁺ luminescence increased by 4 times. Under 972 nm Ti-sapphire laser excitation, high room temperature upconversion emissions were observed from Er³⁺ doped SLGT sample at 415, 540, 554, and 667 nm. The formation of nanocrystals was aided by changes in optical spectral characteristics.
