Abstract:
Diamond has remarkable thermal and mechanical properties including extreme thermal conductivity, low thermal coefficient of expansion, hydrophobicity, chemical inertness, and ultra-hardness for scratch-resistance and durability. Coupled with high optical transmissivity over a broad wavelength range (UV-VIS-IR), these attributes make diamond an ideal protective coating for optical components and windows used in extreme environments. In this work we investigate the use of Nanocrystalline Diamond (NCD) based multi-layer structures for the protection of MWIR windows, an application that is critical for sustained sensor operation in extreme battlefield conditions. The effort incorporates layer designs based on measured optical constants and commercially available optical design software (Open Filters). Protective films deposited via CVD techniques on optical quality silicon substrates are characterized for mechanical and optical properties including hardness, stress, transmissivity, and optical constants. Measured results demonstrate NCD viability as a protective coating for a broad range of optical applications. The technology is compatible with large area scaling, low-temperature deposition on sensitive surfaces, and, in future adaptations, will support integrated transparent electronics.

Abstract:
Hardening is a method for protecting metal equipment, metal tools, or important components against erosion, tension, and corrosion. In this respect, a thin layer of corrosion-resistant metal is welded on the surface of the workpiece. This process is very useful for improving resistance against abrasion and corrosion. As nanotechnology develops, one of the most important properties of materials, namely their surface resistance against destructive phenomena such as abrasion, impact, erosion, and corrosion, could be improved. Enjoying favorable abrasion resistance is considered as one of the most important indicators of piece-part quality in many industries. The useful life of piece-parts could be significantly increased by applying abrasion-resistant coatings, reducing repair or replacement costs associated with damaged parts subsequently. Besides, this process amounts to an inexpensive method in the production of parts and is economically justifiable. Abrasion- resistant coatings could be applied to mining equipment exposed to abrasion and impact. This study is focused on measuring the abrasion resistance of Nano high entropy alloy/Graphene Composite on Copper sulfide ore. This Nano coating is a modern method for hardening the ball and lining of mining grinding mills.

Abstract:
Environmental and economic concerns have caused urgent transitions of fossil fuel-based automotive-vehicles to hybrid-vehicles and, now to fully electric vehicles. In general, the expected driving range of electric vehicles is dependent upon energy density of the batteries. Although batteries provide high energy density, they suffer from several drawbacks such as low power density, safety, limited life cycle, longer charging and discharging cycles, and recyclability. To overcome these drawbacks, supercapacitors are emerging as novel energy storage devices with significantly higher power density compared to batteries. For example, hybrid transit buses in China operate using supercapacitors packs, which estimates to provide improved fuel economy up to 30-50%. Using supercapacitors could also provide the additional advantage of energy regeneration while braking, instead of thermal loss and add to improved fuel economy. In this talk, we will report synthesis, characterization and energy applications of nanostructured carbon. Our research showed that various forms of carbon such as bio-waste derived carbon, graphene, composite of graphene could be used for energy storage as well as energy production via water splitting. Water splitting generates hydrogen which could be used as a green fuel. For example, carbon derived from tea leaves could for Li-ion supercapacitors. The energy storage capacity depends on the electrolyte and temperature. Carbon from tea showed a specific capacitance of 292 and 246F/g in 3M KOH and LiOH electrolyte, respectively with outstanding cyclic stability (100% capacitance retention up to 5,000 cycles). A supercapacitor device fabricated using bio-derived carbon should about 95% retention in charge storage capacity on increasing current density from 1 to 12mA/cm2, confirming high rate stability of the supercapacitor. It was further noted that charge storage capacity increases with increase in temperature. Our studies suggest that nanostructured carbon could be used for an electrode in next-generation energy storage and production devices
