Platinum is recognized as a harmless metal and is widely used in many industrial products. Recent studies have proposed that platinum in the form of nanoparticles has antioxidant properties, suggesting potential uses for platinum nanoparticles as additives in foods and cosmetics, with direct exposure consequences for…
A method for estimating Wilson parameters on the basis of solubility parameters and molar volumes has been adopted to correlate vapor–liquid equilibria of polar mixtures such as binary systems containing ethers, ketones, ethanol, and water. The correlation performances are examined and discussed.
We have demonstrated the glucan polymer-mediated syntheses of titania at room temperature, which is an energy-conserving and environmentally benign synthetic pathway. Wormhole-like particles (both rutile and anatase) with high surface areas and quasi-sphere-shaped particles (anatase) were obtained for chitosan, sodium…
Using in-situ emulsion polymerization, the exfoliated nanocomposites were prepared from vinyl acetate (VAc) and organic montmorillonite (OMMT) through five different experimental conditions. The different experimental conditions and OMMT had little effect on the structure of PVAc–OMMT, but significant effect on the dy…
Upon examination of shape memory alloy (SMA) actuation designs, there are many considerations and methodologies that are common to them all. A goal of CASMART’s design working group is to compile the collective experiences of CASMART’s member organizations into a single medium that engineers can then use to make the b…
Silver nanoparticles (NPs)-deposited tungstosilicate (Ag/SiW12/Ag) microtubes were obtained by a redox reaction between the heteropoly blue microtubes and Ag+ ions. The Ag/SiW12/Ag microtubes were characterized by FT-IR and XPS spectroscopy. Their morphology was examined by ESEM-FEG, showing that the microtubes kept t…
Depending on the specific event scenario and on the purpose of the analysis, the availability of calculation methods that are not implemented in the standard system thermal hydraulic codes might be required. This may imply the use of a dedicated fuel rod thermomechanical computer code. This paper provides an outline o…
Developing stronger, safer and more cost-effective structural materials for the new generation naval ships is the focus of ongoing research at University of Mississippi. The light-weight nanoparticle reinforced glass/carbon polymeric based composites and structural foams for blast, shock and impact mitigation are emph…
In this investigation, efforts were given to develop carbon-nanofiber-reinforced polybenzimidazol nanocomposite for space application. Processing of polybenzimidazol was carried out by using polybenzimidazol in powder and solution forms. Thermomechanical properties of compression-molded polybenzimidazol, unfilled poly…
Silicon nanocrystals (Si NCs) may be both unintentionally and intentionally doped with nitrogen (N) during their synthesis and processing. Since the importance of Si NCs largely originates from their remarkable optical properties, it is critical to understand the effect of N doping on the optical behavior of Si NCs. O…
A manganese and three isomorphous lanthanide complexes, [Mn(1,10-phen)(L)(H2O)] (1) and {[Ln(1,10-phen)2(H2O)2] [Ln(1,10-phen)(H2O)3](L)3}·2.5H2O (Ln = Pr (2), Nd (3), La (4); L = 4,4′-bis(2-sulfonatostyryl)biphenyl) are reported. The manganese solid can release the coordinated water to form a dehydrated phase, which…
A boronium-based paraquat analog undergoes reductions at more negative potentials than paraquat itself, making it a promising building block for electroactive materials.
Stainless steels are often used instead of painted carbon steels or weathering steels in architecture or construction for aesthetic reasons and/or when maintenance cost reduction is considered. With duplex stainless steels the investment cost can also be significantly reduced using their better yield and tensile stres…
This paper addresses a three-dimensional model for isothermal stress-induced transformation in shape memory polycrystalline materials in presence of permanent inelastic effects. The basic features of the model are recalled and the constitutive and the three-dimensional quasi-static evolution problem are proved to be w…
Lithographic scaling has been driven by improvements in wavelength and numerical aperture historically. In the semiconductor industry, the H2O base 192 immersion technique has still been main exposure tool combined with various low-k1 techniques, such like off-axis illumination, phase-shift mask and so on. The focus i…
High aspect ratio (AR) gold nanorods (NRs) attract great interest for biomedical applications due to their novel physicochemical properties. Here, we report a facile method for preparation of high AR gold NRs through a seedless surfactant-mediated protocol with the additive of nitric acid. High-resolution transmission…
Full DFT based quantum mechanical studies reveal that zero dimensional porous structures, especially the newly proposed phosphorus incorporated organic cages, can be excellent catalysts for the dehydrogenation of ammonia borane.
Abstract Production of walleyes Sander vitreus in extensive culture ponds may be variable depending on pond substrate. The goal of this research was to determine whether fish performance and physiochemical differences existed between ponds lined with ethylene propylene diene monomer (EPDM) and ponds with earthen subst…
Single crystals of glycine doped potassium acid phthalate (KAP) have been grown from low temperature solution growth method by employing slow evaporation of the solvent at room temperature. The grown crystal was subjected to various studies such as X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), UV-visible…
Fabrication of nanostructured ZnO thin films is a critical process for many applications based on semiconductor devices.So on understanding of the electrochemical deposition mechanism is also fundamental for knowing the optimal conditions on growth of ZnO nanorods by electrodeposition.In this paper the electrochemical…
