The discovery of carbon nanotubes is one of the remarkable achievement in the field of material science and it is a great advancement of Nanotechnology. A carbon nanotube is an expedient material used in several domains and paves way for the welfare of humans in many ways. Carbon nanotubes are nanosized tubes made from graphitic carbons and it is well known for its exclusive physical and chemical properties. The market demand for the nanotubes has increased progressively due to its size dependent, structure and mechanical properties. The carbon nanotubes possess high tensile strength and it is also found to be the durable fibre ever known. It is also found to possess exceptional electrical properties. The carbon nanotube composites have an excellent young’s modulus and higher tensile strength same as graphite carbon. This review plots the properties of carbon nanotubes and portrays the planning and properties of carbon nanotube composites. The wide application of carbon nanotube composites is also explained.

The availability of sustainable and environmentally friendly energy sources is one of the biggest challenges faced by scientists and engineering communities. First of all, the fossil fuels used to meet existing energy demands cause the depletion of resources, the increase of greenhouse gas emissions, and eventually destruction of nature. Polymers have many industrial application areas due to the ease of processing, the reasonable price and the ability to modify with the desired features. Biopolymers have become a focus of attention in terms of the polymer sector because biomass can be separated into harmless products such as CO2 and H2O in the natural environment and can have sustainable resources. The studies on biomass and hydrogen fuel cells are more advantageous than other alternative and clean energy sources because they have the continuous energy supply, compact design, and wide application areas without being dependent on nature. In practice, the polymer electrolyte membrane fuel cells are pinched among the other fuel cells. For this purpose, in this chapter diffusion, transport and water absorption properties of eco-friendly polymer composites generally used are discussed.

In early composite materials, the use of petroleum based fibers such as glass and carbon fibers, aramid etc. was common. In order to reduce the dependency on petroleum based sources and environmental pollution, researchers have focused on the search for alternative sources. Natural fibers are abundant, recyclable and biodegradable plant derived materials. Besides, thanks to good physical, thermal and mechanical properties, natural fibers become promising alternative for composites. This review includes information about natural fiber reinforced composites’ components, manufacturing methods, mechanical properties and applications.

In this chapter, bamboo fiber with parallel and anti parallel orientation has been introduced in the Unsaturated polyester (UPE)/ Epoxidized Soybean Oil Acrylate (ESOA) blend. The reinforced fiber mats were treated with NaOH and NaOH-silane to improve the stiffness and strength of the composites. Parallelly oriented fiber reinforced composite showed improved glass transition temperature. The mechanical, thermal, storage modulus and tribological properties are highly improved for parallel fiber oriented composite. Also alkali-silane treated fiber reinforced composite show optimum properties than alkali treated and raw fiber based composites. Anti parallelly oriented composites show reduced performance due to pull out of fibers. The FTIR analysis of all the composites was observed for the first time with valid reaction mechanism. So this new partially biodegradable composite can open a new door for potential application in various fields. This composite may be used as an alternating material to wood for various indoor and outdoor applications.

The area of sorption and diffusion behaviour of wood/plastic composites has gained considerable attention during the last decade owing to the variety of applications it offers. When it comes to polymers filled with wood particles there are essentially two major limiting factors that controls the final products end user applications; 1) diffusion and 2) sorption/solvent uptake of (especially moisture) the product, since these two processes lead to property degradation in the composite materials. The properties and end use application of a given product can be predicted thorough the knowledge of the parameters like diffusion, sorption and permeation coefficients. Transport (sorption, diffusion & permeation) properties of wood plastic composites (WPC’s) are now a day’s one of the most intensively researched areas owing to its significance in materials science. Liquid transport through plastics is one of the most extensively researched fields in materials science. Present chapter provides a brief insight into the transport (mainly moisture/water) properties of wood/plastic composites. Keywords: Wood particles, wood plastic composites, diffusion coefficient

Polymer electrolyte membranes (PEM) with good properties are essential for the improvement of electrochemical operations. The increase in properties of polymer electrolyte membranes will develop the performance of polymer electrolyte membranes in the fuel cells. The importance of polymer electrolyte membranes is increasing recently due to its activity and simplicity in energy associated applications like automobiles and various portable applications. PEM has various properties like proton conductivity, chemical stability, mechanical properties, thermal stability and so on. These properties are enhanced and influenced by various factors like morphology, the molecular weight of the membranes, chemical structures, cross linkages etc. The present chapter attempts to summarize about the properties of polymer electrolyte membrane involved in the different types of electrochemical utilizations. Keywords: Polymer electrolyte membrane, fuel cells, morphology, proton conductivity, chemical structure.

Following nuclear decay, a daughter atom in a solid will "stay in place" if the recoil energy is less than the threshold for displacement. At high temperature, it may subsequently undergo long-range diffusion or some other kind of atomic motion. In this paper, motion of 111Cd tracer probe atoms is reconsidered following electron-capture decay of 111In in the series of In3R phases (R= rare-earth). The motion produces nuclear relaxation that was measured using the method of perturbed angular correlation. Previous measurements along the entire series of In3R phases appeared to show a crossover between two diffusional regimes. While relaxation for R= Lu-Tb is consistent with a simple vacancy diffusion mechanism, relaxation for R= Nd-La is not. More recent measurements in Pd3R phases demonstrate that the site-preference of the parent In-probe changes along the series and suggests that the same behavior occurs for daughter Cd-probes. The anomalous motion observed for R= Nd-La is attributed to "lanthanide expansion" occurring towards La end-member phases. For In3La, the Cd-tracer is found to jump away from its original location on the In-sublattice in an extremely short time, of order 0.5 ns at 1000 K and 1.2 ms at room temperature, a residence time too short to be consistent with defect-mediated diffusion. Several scenarios that can explain the relaxation are presented based on the hypothesis that daughter Cd-probes first jump to neighboring interstitial sites and then are either trapped and immobilized, undergo long-range diffusion, or persist in a localized motion in a cage.

15-5PH stainless steel is widely used in the aerospace industry, from precision fuse pins to forged products, due to its various high-performance properties. However, there is little systematic evaluation of heat treatment responses, especially at ultra-high temperatures above 650°C (1200°F). The objective of this work was to evaluate the mechanical and microstructural properties of 15-5 PH stainless steel at various heat treatments. Multiple heat treatment parameters were tested. The samples tested had varied chemical compositions because they were from different vendors. The experimental work included multiple aging temperatures, time, heating rates, and the effects of multiple aging treatments. A total of 38 different heat treatments were conducted on these specimens. There was a linear correlation between hardness and ultimate and yield strength. Optical microscopy showed martensitic structures with very fine grains in all the tested samples. Scanning Electron Microscope (SEM) images showed ductile fracture in all the samples.
