The structures of Pt clusters on nitrogen-, boron-, silicon- doped graphenes are theoretically studied using density-functional theory. These dopants (nitrogen, boron and silicon) each do not induce a local curvature in the graphene and the doped graphenes all retain their planar form. The formation energy of the sili…
The success of anti-cancer drug targeting is depends on the ability of the therapeutics to reach their desirable cellular and intracellular sites and minimizing action at the nonspecific sites. In the present study, anti-human epidermal growth factor receptor (HER-2, ErbB2) antibody anchored nanoparticles were prepare…
The magnetic and crystal structures of the Pr0.5Sr0.5CoO3 metallic ferromagnet have been studied by the neutron diffraction technique. It is demonstrated that below 150 K, the compound is mesoscopically separated into two crystalline phases with different spatial symmetries and with different directions of the magneti…
Polyaniline and polyaniline/gold films were prepared by potentiodynamic oxidation of aniline in 1 M H2SO4 aqueous solution, and their electrochromic properties were investigated by UV-Vis and Raman spectroscopy. Both tetrachloroaurate and gold nanoparticles were used to deposit gold onto or inside the polyaniline film…
The phase field model is adopted to study the magnetoelectric coupling effects in vertical heteroepitaxial nanocomposite thin films. Both the lateral epitaxial strains between the film and the substrate and the vertical epitaxial strains between the ferroelectric and ferromagnetic phases are accounted for in the model…
Based on the idiographic character of collagenous domain of human type III collagen, a recombinant human gelatin monomeric gene (gel) was designed and synthesized. All hydrophobic amino acids (proline excluded) were replaced by hydrophilic amino acids to improve the hydrophilic properties, and the codons encoding amin…
Hyperbranched polyurethanes [HBPUs] and vegetable oil based polymer nanocomposites have been drawing an imperative attention for their plentiful advantages across a spectrum of potential applications. This study divulges the rheological behaviors of Mesua ferrea L. seed oil modified HBPU/multiwall carbon nanotube [MWC…
Major problems with biological heart valves post-implantation are associated with progressive structural deterioration and calcification attributed to glutaraldehyde processing, dead cells, and cell fragments present in the native tissue. In spite of these problems, glutaraldehyde still is the reagent of choice. The r…
In this review, we report the recent advances in the construction of composite molecular nanoarchitectures of porphyrins and nanoscale carbon materials such carbon nanotubes (CNT), graphenes and polycyclic aromatic hydrocarbons (PAH) for photoinduced electron transfer and light energy conversion. First, we state novel…
This chapter presents a review of the most recent and systematic works performed on the study of the effect of atomic order on the structural and magnetic properties of Ni-Mn-Ga ferromagnetic shape memory alloys. It is shown that a correlation between long-range atomic order and the martensitic and Curie temperatures…
Chalcogenide glasses are suitable for far-infrared and imaging applications. In the present study, Sb10Se90-xGex (x=0, 19, 21, 23, 25, 27) system has been chosen to study structural transformations via physical parameters. Bulk samples with x = 0, 19, 21, 23, 25 and 27 have been prepared using the melt-quenching techn…
The properties of high-strength and high-elasticity film-forming adhesives, high-strength cold- and hot-setting adhesive pastes, functional adhesives for metals, and various nonmetal and composite materials are reviewed. The properties of self-adhesive materials of different grades used for temporary repair of airfram…
The chiral properties of an artificial anisotropic structure composed of microhelices are numerically simulated using the example of a sample developed by a team of authors from the Institute of Semiconductor Physics of the Russian Academy of Sciences. It is shown that this artificial structure can exhibit strong chir…
This paper focuses on the determination of the speciation in calcium-silicate glasses from Raman spectra and describes in detail the statistical method to determine quantitatively the speciation from collected spectra. We developed a novel statistical method employing optimization technique to determine the number of…
The objective of this study was to investigate the feasibility of using the bio-oil generated from the Mississippi State University's (MSU's) fast pyrolysis process as part of a polymeric diphenylmethane diisocyanate (pMDI) binder system for flakeboard production. The bio-oil was obtained from the pyrolysis process of…
The objective of this study is to present an approach to predict ageing due to thermal cycling by start and stop cycles in the lifetime estimation of hydroelectric generator stator windings. In this study a multi-stress electro-thermo-mechanical ageing model was applied for remaining lifetime calculations of stator wi…
A different mechanism to achieve total transmission through an otherwise opaque screen, based on an inherently ultra-broadband tunneling mechanism that can span from DC to the visible range is introduced. In this talk, the physics of this anomalous tunneling phenomenon which is in many ways analogous to regular Brewst…
Qualitative comparison of the effect of ultrasonic treatment and annealing on the structural relaxation of a two-dimensional nanocrystalline material after severe plastic deformation has been performed by the molecular-dynamics method. The treatments of both types lead to a decrease in the dislocation density and to a…
The crystal structure of lead and indium nanoparticles produced by the introduction of lead and indium into porous glasses with an average pore diameter of 7 nm at a high pressure is studied by X-ray diffraction. In contrast to the lead nanoparticles, the indium nanoparticles exhibit pronounced anomalous asymmetry of…
The paper presents the scientific basis and technical implementation of a method for obtaining oxygen by extraction from air using an electrochemical cell based on a solid oxide cell (SOC) with anion-conducting solid electrolyte. A nanopowder of a weak aggregate of the YSZ solid electrolyte and LSM fine powder was use…
