The use of rubber/metal bonded composite is growing in the offshore industries as well as in the automotive components.Maintaining a good adhesion between rubber to substrate bond is a crucial importance in ensuring a satisfactory product performance in service.Bond failure attributes to the severe product performance…
Nanofibers with high surface-to-volume ratio are of significant applications. This paper proposes a novel method for fabrication of particle-like beaded nanofibers and their daughter nanofibers, which are ejected from the surface of charged jets. Polyvinyl alcohol/ash solution is used in the electrospinning process.
Abstract Dynamics of micro droplets, coalescence underneath an inclined hydrophobic surface is explored, experimentally as well as computationally. Such a situation often arises during dropwise condensation, atmospheric dew formation, condensation in green houses, and metal vapor condensation during enrichment process…
Color filters (CFs) are important elements for making color images in liquid crystal displays (LCDs) and other imaging devices. A colored layer is fabricated with colorants of red, green, and blue from either dyes or pigments. These colorants are arranged uniformly and make up the CF while also converting white backli…
This chapter provides a materials perspective to recent developments in biomimetic underwater adhesives for functionalizing a wide range of surfaces. The first part of the chapter is devoted to providing an overview towards mussel adhesion as the source of inspiration. The focus is then shifted to review fully synthet…
Zinc doped cobalt ferrite powders were prepared by the solid state reaction method. The effect of zinc substitution on structure, morphology and magnetic properties was investigated. The X-ray analysis confirmed existence of the single phase cubic spinel structure, while Rietveld refinement data showed increasing of l…
Carbon Nanotube Field-Effect Transistors (CNFETs) are excellent candidates for building highly energy-efficient digital systems. However, imperfections inherent in carbon nanotubes (CNTs) pose significant hurdles to realizing practical CNFET circuits. In order to achieve CNFET VLSI systems in the presence of these inh…
The uniaxial tensile and compression tests of the Cu∑ 5 grain boundary (GB) with and without segregated interstitial boron have been performed using first principles method based on density functional theory. Results show that boron enhances the cohesion of Cu∑5 GB and improves the mechanical property of Cu significan…
Based on transformation optics theory, an elliptical scattering-shifting cloak is designed and the constitutive parameter tensor expressions are derived. Then full-wave simulations to mimic the ellptical dielectric and conductor cylinder are obtained by using finite-element software. The results of full-wave simulatio…
The interlayer energy of the twisting bilayer graphene is investigated by the molecular mechanics method using both the registry-dependent potential and the Lennard-Jones potential. Both potentials show that the interlayer energy is independent of the twisting angle θ, except in the two boundary regions θ≈0° or 60∘, w…
Three phase induction motors consume 60% of industrial electricity. Just 1% increase in efficiency of all the motors in India will save 500 MW powers which needs the initial generation cost of 2000 crores. The efficiency of an induction motor can be substantially improved by controlling the voltage to frequency ratio…
The Al2O3/Al2O3-ZrO2(3Y) laminated composites were prepared with different starting powders to optimize the preparation process and mechanical properties.The influence of phase structure and morphology of powders on microstructure and properties of laminated composites were investigated via X-ray diffraction(XRD),fiel…
Parent material of black soil in the Northeast China is mainly quaternary sediment.Based on chemical composition and XRD of two kinds of soil particles(less than 2 μm in diameter) from black soil profile,laterite parent material and loess parent material,the results show that the black soil in Northeast China develope…
Arthropod cuticle is an excellent biological model system of a hierarchical nanocomposite for studying inner structure and architecture in connection with mechanical performance. While the hierarchical structure of non‐mineralized arthropod cuticle has been widely studied, only recently the particular biomineralizatio…
Inverse molecular design has emerged as an attractive computational approach to take on the challenges in materials discovery. We present a conceptual formalism for the idea of inverse molecular design as it is implemented to perform optimizations that searches along the molecular property hypersurfaces constructed di…
Carbon nanotubes-supported 12-tungsto-silicic materials (referred as CNT- SiW12-x, where x is the loading of H4SiW12O40, abbreviated as SiW12 were prepared and characterized by means of FTIR, XRD, and polarography. The prepared catalysts and attached onto glassy carbon (GC) electrodes by using polyvinylidene difluorid…
A novel ternary electrolyte system that consists of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide (EMITFSA), LiTFSA, and tris(trifluoroethyl)phosphate (TFEP) has been developed as a nonflammable electrolyte for advanced electrochemical capacitors.
