Development of Characterization Techniques of Various Nanocomposites: A Review
type: item
description: Abstract Nanotechnology is basic research and development that is a phenomenon in laboratories all over the world. A nanometer (nm) is one thousand millionth of a meter. For comparison, a red blood cell is approximately 7,000 nm wide and a water molecule is almost 0.3 nm across. Nano-scale is a scale where the properties of materials can be very different from those at a larger scale. Nanoscience is a study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ considerably from those at a larger scale. Composites made from particles of nanosize ceramics or metals smaller than 100 nm can suddenly become much stronger than predicted by existing materials. This review focuses on overview of characterization methods and their advantages for research and development perspectives.

type: item
description: Abstract Zinc sulphide nanoparticles are very good candidate for optoelectronic applications. In this paper we have reported green synthesis of zinc sulphide nanoparticles using Musa peels available in abundance as organic waste. Various precursor ratios and various extract concentrations were used. The samples obtained were analyzed using optical and morphological characterization. Strong blue shift in absorption edges was observed for increasing concentration of thiourea. It also was influenced by concentration of peel extract, which indicates the effective role of peel in nanostructure formation. The samples also show reasonable luminescence in visible or UV region to make them suitable for various optoelectronic applications.

Influence of Dip Cycles on the Structural, Optical and Morphological Properties of CdS-SILAR Deposited Thin Films
type: item
description: Cadmium sulphide (CdS) thin films were deposited on a glass substrate by a relatively simple and cost effective successive ionic layer adsorption and reaction (SILAR) method at temperature 80ºC at different deposition cycles. For a fine nanocrystalline thin film growth, the parameters include concentrations of cationic and ionic precursors, number of immersion cycles, and the immersion time. A study was made to know how dip cycles affects the structural, surface morphological and optical properties of the film using X-ray diffraction (XRD), EDAX, scanning electron microscopy (SEM) and UV-VIS (ultraviolet visible) spectrophotometer. The deposited CdS thin films were found to be greenockite αCdS film with a strong preferred orientation along the (002) plane exhibit hexagonal phase with optical band gaps between 2.38 and 2.70eV. The band gap with a value to a certain extent larger than the distinctive value of the bulk CdS (2.42 eV), can be ascribed to quantum confinement effects due to the nanometer crystallite size of the CdS thin films.

A Study on the Synthesis and Characterization of Silver Metal Nano Particles with Acrylic Acid– Acrylamide (Aa) Copolymer as Mediating Agent
type: item
description: Silver metal nano-particles (MNP) have been synthesized by chemical methods with acrylic acid- acryl amide (AA) copolymer as mediating agent. Formation and interaction of silver metal nano- particles with AA copolymer has been confirmed by ultraviolet–visible (UV-VIS), Fourier Transform Infrared (FTIR) techniques. Thermal and morphological properties of the composite have been studied by Differential Scanning Calorimetry (DSC) and Scanning Electron Microscope (SEM) techniques. Change in intensity together with shift of FTIR absorption bands in the regions of 3500–3150 cm-1 and 1700 cm-1 position in an evidence for interaction of silver metal particles with amide (CONH2) and carboxylic acid functional (COOH) groups of the copolymer. Presence of 280 nm, 350 nm and 450 nm optical absorption bands indicate the formation and existence of silver nano metal particles in copolymer matrix. DSC thermogram indicates that the thermal stability of the complex is more than the copolymer. The silver nano metal particles are found to lie on the surface of copolymer matrix.

Growth and Description of Cu Nanostructure via a Chemical Reducing Process
type: item
description: Chemical reduction process has been employed to produce copper (Cu) nanostructure by using L-ascorbic acid. The use of L-ascorbic acid makes this process cost effective. In this process, copper chloride (CuCl2.2H2O) has been used as a precursor to produce the Cu nanostructure. They were characterized through UV-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The experimental findings revealed that the molar concentrations of L-ascorbic acid played an important influence over the particles size. The result observed was the average particle size ~50 nm.

Piezoelectric Nanoparticles Loaded with Curcumin for Cancer Treatment
type: item
description: Conventional cancer chemotherapy treatments are often compromised by systemic toxicity which starts from the lack of tumor specificity of administered anticancer drugs. The side effects limit the dose of the drug that can be administrated, making effective cancer treatment difficult. Nanoparticle-based drug delivery has the potential to overcome this challenge by targeted delivery to tumor and taking the advantage of tumor’s natural leaky vasculature to increase the accumulation of drug-loaded nanoparticles in the tumor interstitium. By loading anticancer drug into nanoparticles, the more favourable pharmacokinetics and tuneable bio distribution of nanoparticles which can increase in the efficacy of the drug, can be achieved. Drug molecules loaded into a nanoparticle may also be protected from degradation and oxidation while in circulation. In this project, we are intending to accomplish an effective cancer treatment in a more economical and efficient manner without using chemical dosage, radiation exposure or any other surgical methods minimizing the side effects. Here, the Rochelle salt crystals are used to accomplish this by utilizing its piezoelectric property. Since the Rochelle salt comes under food additive chemicals and it is easily excreted in the urine without metabolizing in the body, it is a biocompatible material. The nanoparticles must be biocompatible and we are choosing this material in combination with curcumin and are administered after polymer encapsulation. Curcumin thus becomes an answer to several limitations in the present day techniques. Curcumin loaded Rochelle salt nanoparticles will be administered after the polymer encapsulation using PCL and PEG, with antibodies for tumor specificity which will ensure specific delivery. Ultrasound applied externally can initialise the piezoelectricity in Rochelle salt which will disintegrate the cancer cells.

The method is very effective to understand the localized variations in mechanical behavior of the composites that are influenced by precipitation of reinforcements. The composites were synthesized en-route powder metallurgy, the matrix and reinforcements were ball milled which facilitated the study of the morphological and structural aspects involved in powder particles during structural evolution and morphological changes of powder particles during ball milling. Hardness and elastic modulus values of powder particles were measured by nanoindentation method. Nanoindentation tests were done in current work on specimens prepared from five different compositions viz. Al, Al/5 wt% B4C, Al/0.5 wt% CNT/5 wt% B4C, Al/1 wt% CNT/5 wt% B4C, Al/2 wt% CNT/5 wt% B4C scratch tests were also performed to define the tribological characteristics of materials, since scratch resistance and friction are core properties of any composite material. The nano-hardness is measured in GPa scale and is found to vary between 0.5 and 0.62 GPa, while the elastic modulus is found to vary between 110 and 122 GPa for specimens of different compositions.

Wear Characterization of Al/B4C/CNT Composites for Different Alloying Composition
type: item
description: Wear is a surface phenomenon that occurs predominantly at the surface of the material. It is majorly due to the rubbing action between two surfaces that is attributed to solid state contact. As wear is a material removal phenomena occurring at the outer surfaces, it is indeed very apt to develop materials that have wear resistant characteristics. Henceforth in the current work, it is therefore judicially justified to develop a composite material with different proportions of carbon nanotube (CNT) and boron carbide (B4C) for obtaining wear resistant characteristics. The objective of present work is to develop an experimental plan to find the important factors and the combination of factors influencing the wear phenomenon to optimize the wear characteristics such that the minimum wear rate and COF is achieved. The plan of experiments are developed based on an orthogonal array, the main aim of orthogonal array is to relate the sliding speed, applied load and sliding distance. The parameters henceforth considered are distinct and affect the performance of composite materials. Taguchi Genechi method gives an overview of conceptual approach that takes into account S/N ratio for optimizing the experimental variables and identifying the significant factors.

Structural and Photoluminescence Studies of Porous Anodic Alumina Templates Prepared using Different Electrolytes
type: item
description: The effect of different electrolytes on the structural and optical properties of porous anodic alumina (PAA) was investigated. PAA templates were synthesized using different electrolytes namely; oxalic, phosphoric, sulphuric and chromic acids maintained at two different temperatures, 18 and 27°C respectively. PAA templates were prepared using two-step anodization process in 0.3 M of sulphuric acid at 20 V, 0.3 M of oxalic acid at 40 V and 0.3 M of phosphoric acid at 90 V, and 0.3 M chromic acid at 50 V. Highly uniform hexagonal cell structure was obtained for the PAA templates synthesized using oxalic acid. It was found that the electrolyte temperature influenced the morphologies and regularities of PAA templates formed on aluminium substrate. X-ray diffraction analysis shows that PAA is in amorphous state. Photoluminescence (PL) analysis showed that a blue PL band occurs in the wavelength range of 350–550 nm. The experimental results indicated that the oxygen-related defect centers, F+ centers, are responsible for the photoluminescence of PAA templates. Among the different electrolytes used in our experiments, oxalic acid showed the highest peak in the emission spectra in PL.

SnO2 Nanoparticles: Preparation, Characterization and Humidity Sensor Application
type: item
description: The microwave-assisted synthesis method is used to prepare SnO2 nanoparticles for the application of humidity sensor, because of oxygen vacancy in the lattice. Microwave-assisted method is very simple, low cost and rapid heating method. Room temperature ionic liquids and tin source were used in the reaction as precursors. The obtained SnO2 nanoparticles were characterized by X-ray diffractometer, particle size analyser, Fourier transform infrared spectroscope, and thermo gravimetric-differential thermal analyser. The humidity sensor application was investigated by digital electric meter. The SnO2 nanoparticles confirmation was done by XRD and the average crystallite size was 28 nm. The strong stretching bond observed at 880 cm-1 confirmed the nanoparticles formation. The weight loss of the material observed as 3.7%, infers the high stability of nanoparticles. The resistance value of the SnO2 nanoparticles decreases along with increasing of relative humidity; because of this reason, the sensitivity of the nanoparticles increased.

Efficient Green Synthesis of TiO2 Nanoparticles Using Murraya koenigii Leaf Extract
type: item
description: Green synthesis of nanoparticles by plant extract is at present under exploitation due to eco-friendly, non-toxic and inexpensive process. Titanium dioxide (TiO2) nanoparticles were synthesized by ultrasound assisted sol-gel precipitation method using titanium tetra-isopropoxide as a precursor and Murraya koenigii leaf extract as a reducing and stabilizing agent. The leaf extract was prepared under various solvent media such as ethanol and distilled water under controlled ultrasonication. Due to effective ultrasound, the extraction of chemical agents from Murraya koenigii leaf was in a large extent. The effect of various leaf extracts on size of TiO2 nanoparticles was studied using transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and photoluminescence spectroscopy (PL). The nanoparticles prepared from ethanolic leaf extract were found to be smaller and spherical in shape (~2–15 nm) as compared to leaf extract prepared using water (~15–30 nm). Besides this, X-ray diffraction (XRD) study shows TiO2 of anatase form. Moreover, the band gap values of TiO2 nanoparticles were found to be 3.26 and 3.17 eV for ethanolic and water leaf extracts, respectively studied from PL spectra. The FT-IR spectra of TiO2 nanoparticles exhibit a prominent peak at 714 (Ti-O-Ti bond), 1642 (N-H) (O-H stretching).
