Role of Nanotechnology and applications in today’s Material World!!!!

Nanotechnology devices perform both basic and applied research in areas that have potential impact on electronics technology for the Navy, Marine Corps, and other components of the Department of Defence. Areas of research include MBE growth and characterization of antimonide-based compound semiconductors for low-power high-electron mobility transistors, p-channel field-effect transistors, heterojunction bipolar transistors, hetero-barrier varactors, and mm-wave diodes; carbon nanotubes for chemical detection; graphene for electronics; surface-enhanced Raman spectroscopy from nanowires for chemical sensing; UHV surface science; surface infrared spectroscopy; quantum-chemical modelling of chemical warfare agents and simulants; and gold Nano cluster chemiresistor sensors.

Graphene is a relatively new carbon-based material with high potential for new fundamental science and technological applications. Graphene is a single sheet of graphite, which is either exfoliated from bulk graphite onto a substrate or "grown" by desorbing Si at high temperature from a SiC substrate.

Growth and Surface Properties of Semiconductor and Metal Oxide Nano-wires:

One-dimensional structures, such as carbon nano tubes and semiconductor nano wires, are currently of great interest due to their unique physical properties and potential applications, including Nano scale devices and sensors. We have been investigating a number of nano wire systems, from the perspective of growth mechanism, surface properties, as well as potential applications, especially to sensing.

Infrared spectroscopy is being used to study the vibration spectra of adsorbed species in vacuum, non-vacuum and liquid environments. The focus is on the study of surface reactions and on identifying both strongly-adsorbed stable species and also reaction intermediates and weakly-adsorbed moieties that are present only under steady-state conditions. The materials of interest are primarily semiconductors and dielectric materials in bulk, thin-film or Nano-structure form. Experiments in vacuum or in the presence of gas-phase reagents use primarily reflection-absorption spectroscopy.

Ultra-High-Vacuum Surface Science:

Recent effort in the area of UHV surface science has focused on the wide-band gap semiconductors GaN and SiC and insulators ß-Si3N4 and ß-Ga2O3. The interest is in the physical and electronic structure of the surfaces, chemisorption phenomena, metal contact formation and functionalization with organic species.

Novel Materials- Uses in Material Science!!!

The development of Novel Materials with unique properties is critical to advances in industry, medicine, energy systems, microelectronics, aeronautics and many other fields. Our researchers are pursuing a broad range of interdisciplinary projects with tremendous potential for new products and applications. Novel materials research focuses on improving the performance of materials such as plastics, metals and ceramics by manipulating their structures to exhibit new properties for a wide range of products and applications.

This focus issue on 'novel materials discovery' aims to cover the field of predictive tools for studying inorganic and organic materials as well as hybrid materials and Crystals. The discussion of methods and concepts is complemented by the presentation of results on materials that have not been synthesized so far. The field also needs approaches that enable the identification of hitherto unknown trends helping to recognize, differentiate, and understand materials, their properties and their functions. In this context, searching and analyzing existing and presently evolving data bases of materials properties and functions is an equally important crucial task. Once a novel materials target has been identified, developing a synthesis route for it is often a time consuming process, and we invite insights into rational materials synthesis and the synthesis of non-equilibrium phases.

A suite of materials fabrication facilities at Boise State is available for use by industry and business for measurement of magnetic materials, electrochemical and environmental testing, surface analysis, Nano-micro indentation testing, mechanical/environmental testing, electron microscopy and atomic force microscopy.

The issue contains research from materials science, physics, chemistry and bio-physics/chemistry, as well as applied mathematics, statistics and computer science. Indeed, to bring these communities together is a key to the success of any novel materials discovery project.

Join Crystallography Congress 2018 to be held during November19-20, 2018 in Bucharest, Romania. This will be the best opportunity to outreach the large gathering of participants from all around the world and get name recognition at this two-day event. World-eminent speakers, most recent researches, latest techniques and the advanced technologies in crystallography using novel materials are the principal features of this conference.

Do Hybrid Perovskite Solar Cells increased performance of Neutrons??

The fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials is the neutron scattering. This behavior of the perovskite solar cells will enable manufacturers to design solar cells with significantly increased usage and efficiency.

To study the relationship between the material's microscopic structure and its optoelectronic properties scientists used photoluminescence measurements, along with neutron and x-ray scattering and establish how hydrogen bonding plays a key role in the material's performance to track atomic structural changes in any atom or crystals.

Neutron scattering show the orthorhombic structure of the hybrid perovskite cells that are stabilized by the strong hydrogen bonds between nitrogen substituent of the methylammonium cations and bromides on the corner-linked PbBr6 octahedra.

Hybrid perovskite cells are more easy and efficient in converting light into energy than solar cell materials. These cells are easier to manufacture as they can be spin cast from solution and do not require high-vacuum chambers for synthesis. Hybrid perovskite are made of both organic and inorganic molecules. Neutrons are sensitive to lighter elements like hydrogen that helps in finding the right combination and molecular orientation of the different organic/inorganic components. With the help of neutrons we are able to get information where the atoms are, their temperature, characterization and observe the hydrogen bonding interactions at the atomic scale. The experiment using the perovskite cells and crystals is done to observe how the organic molecules were binding to the lead-bromine component through hydrogen bonds.

This study reveals about the perovskite solar cells how sunlight is being absorbed and what tells the applications for photovoltaic materials. Photoluminescence and x-ray scattering measurements were performed to measure theoretical calculations of crystals along with crystal synthesis. Hybrid perovskites shows the orientation of the organic molecules that impacts the crystal structure and these different methods helps us to design new materials with even greater potential.

Atomic force microscopy (AFM): Graphene-Based Electronics

A straightforward method to adjust atoms in a single bearing on a level graphene surface and effectively controlling sub-atomic arrangement is depend upon to prompt real advance in surface science and sub-atomic designing and above all in the field of materials science.

Graphene is a type of material that is attracting many scientists, students and researchers as a powerful candidate for next generation of electronics materials and in the field of material science due to their unique properties. The graphene surface has three-overlay symmetry, which are thermodynamically equal to each other and along these lines making it hard to adjust the atoms in an arranged or special course.

Atomic force microscopy (AFM) is a type of technique mainly used for detecting surfaces additionally to control sub-atomic arrangement and produces pictures demonstrating the surface uneven layer of precious stone by sliding a test tip over the surface region.

The grey plane represents the graphene surface. The stick-like particles consisting of white, grey, red, yellow white colored balls represent surfactant (sodium dodecyl sulphate (SDS)) molecules. The grey colored reverse pyramid-like structure shows the probe tip of AFM.

At that point the examination on AFM, it demonstrates how AFM tip filtering prompts changes in atomic arrangement on the graphene surface of any material or precious stone. They utilized sodium dodecyl sulphate (SDS), a typical surfactant atom, as a model particle and it forms like ribbon on the graphene surface. It has been observed that SDS strips developed effectively when the relative edge between the ribbon developing hub and the sweep bearing is bigger and adsorbed SDS atoms are really evacuated when they are compelled to pivot under the AFM filtering conditions. This method shows that the AFM scan can help in the 'symmetry breaking' effect of the molecular pattern on graphene.

The idea of breaking the surface symmetry can be used for different purposes, for example, producing sub-atomic circuits in sub-atomic hardware science as well as in related fields that include sub-atomic nanostructures and their arrangement.
