Powder metallurgy includes an intensive variety of approaches wherein substances or components are made of steel powders. Pyro metallurgy contains thermal remedy of minerals and metallurgical ores and focuses to achieve bodily and chemical changes inside the materials to enable recuperation of valuable metals.
General data of metallurgy can help us to extract the metal in a greater possible manner and can used to a much wider range. Nanomaterials and Nano composites: Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than nanometers nm or structures having nano-scale repeat distances between the different phases that make up the material. The idea behind Nanocomposite is to use building blocks with dimensions in nanometre range to design and create new materials with unprecedented flexibility and improvement in their physical properties.
In the broadest sense this definition can include porous media, colloids, gels and copolymers, but is more usually taken to mean the solid combination of a bulk matrix and nano-dimensional phase s differing in properties due to dissimilarities in structure and chemistry. The mechanical, electrical, thermal, optical, electrochemical, catalytic properties of the nanocomposite will differ markedly from that of the component materials. This includes both nano-objects, which are discrete pieces of material, and nanostructured materials, which have internal or surface structure on the nanoscale; a nanomaterial may be a member of both these categories Nanoparticles.

Carbon Nanomaterials: Carbon nanotubes CNT are a class of nanomaterials that consist of a two-dimensional hexagonal lattice of carbon atoms, bent and joined in one direction so as to form a hollow cylinder. Carbon nanotubes are one of the allotropes of carbon, specifically a class of fullerenes, intermediate between the buckyballs closed shells and graphene flat sheets.
Besides these single-wall carbon nanotubes SWCNTs , the name is also used for multi-wall MWCNT variants consisting of two or more nested nanotubes, or of graphene-like strips rolled up into multiple layers like a scroll. Individual nanotubes naturally align themselves into "ropes" held together by relatively weak van der Waals forces. While one can build nanotubes of other compositions, most of the research has been focused on carbon ones; so that the "carbon" qualifier is often left implicit, and the names are abbreviated NT, SWNT, and MWNT.
Advances in Dielectric Materials and Electronic Devices: A dielectric or dielectric material is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor but only slightly shift from their average equilibrium positions causing dielectric polarization.
Because of dielectric polarization, positive charges are displaced in the direction of the field and negative charges shift in the opposite direction.

This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.
Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information-processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed electronic components into a regular working system, called an electronic system; examples are computers or control systems.
An electronic system may be a component of another engineered system or a standalone device. As of most electronic devices use semiconductor components to perform electron control.

The actual application of surface science in related arenas like chemistry, mechanical engineering, electrical engineering and physics is recognized as Surface Engineering. Surface Chemistry achieves the alteration of chemical configuration of a surface by presenting functional groups and additional elements while Surface physics deals with the physical deviations that arise at interfaces.
Techniques tangled in Surface engineering are spectroscopy methods such as X-ray photoelectron spectroscopy, low-energy electron diffraction, electron energy loss spectroscopy, Auger electron spectroscopy, Thermal desorption spectroscopy, ion scattering spectroscopy and secondary ion mass spectrometry, etc. The chemical reactions at the interface is generally termed as Surface Chemistry and is also linked to surface engineering.
It is very significant in the arenas of heterogenous catalysis, electrochemistry and geochemistry. Biomaterials and Tissue Engineering: Tissue engineering is the use of a combination of cells, engineering and materials methods, and suitable biochemical and physicochemical factors to improve or replace biological tissues. Tissue engineering involves the use of a tissue scaffold for the formation of new viable tissue for a medical purpose. While it was once categorized as a sub-field of biomaterials, having grown in scope and importance it can be considered as a field in its own.
A biomaterial is any substance that has been engineered to interact with biological systems for a medical purpose - either a therapeutic treat, augment, repair or replace a tissue function of the body or a diagnostic one. As a science, biomaterials is about fifty years old. The study of biomaterials is called biomaterials science or biomaterials engineering.
It has experienced steady and strong growth over its history, with many companies investing large amounts of money into the development of new products. Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering and materials science. Materials Chemistry and Sustainable Chemistry: Materials Chemistry and Physics including Materials Science Communications is a peer-reviewed scientific journal published 18 times per year by Elsevier.
The focus of the journal is interrelationships among structure, properties, processing and performance of materials. It covers conventional and advanced materials. Publishing formats are short communications, full-length papers and feature articles.
Sustainability can also be defined as a socio-ecological process characterized by the pursuit of a common ideal. An ideal is by definition unattainable in a given time and space. However, by persistently and dynamically approaching it, the process results in a sustainable system. The study of ecology believes that sustainability is achieved through the balance of species and the resources within their environment. In order to maintain this equilibrium, available resources must not be depleted faster than resources are naturally generated.
