An important method of protecting metallic material s against deterioration due to corrosion is by the use of corrosion inhibitors. In the present investigation, corrosion inhibition study of two amino acid comp ounds, 2-amino-N-decyl-3-phenyl propionamide (Inh I) and 2-amino-N-decylacetamide (Inh II) have been perfor…
Both structural refinement using X-ray powder diffraction data and energy calculation using quantum mechanics were used to determine the site preference and the amount of Gd in the host lattice of Gd doped Fe3O4 [Gd(x)Fe(3-x)O4 (x = 0.1)] nanopowder prepared by the sonochemical method. Among possible cation-disorder m…
Interest in engineered metal and semiconductor nanocrystallites continues to grow due to their unique size and or shape dependent optoelectronic, physicochemical and biological properties. Therefore identifying novel non-hazardous nanoparticle synthesis routes that address hydrophilicity, size and shape control and pr…
The U.S. Department of Energy’s Office of River Protection (ORP) is responsible for the retrieval, treatment, immobilization, and disposal of Hanford’s tank waste. Currently there are approximately 56 million gallons of highly radioactive mixed wastes awaiting treatment. A key aspect of the River Protection Project (R…
The first titanium borophosphate Ti[BP2O7(OH)3] has been hydrothermally synthesized and structurally characterized. The compound has a three-dimensional open-framework architecture by linking TiO6 octahedra to the anionic layers [BP2O7(OH)3]4− which are built up from BO3(OH) tetrahedra and PO3(OH) tetrahedra. The comp…
Transport across the membranes of polymersomes remains difficult in part due to the great thickness of the polymer bilayers. Here, we report that dynamic polyion-counterion transport systems are active in fluorogenic polymersomes composed of poly(dimethylsiloxane)-b-poly(2-methyloxazoline) (PDMS-PMOXA). These results…
The organic functionalization of either [60]fullerene or MWCNTs with a highly efficient organogelator has allowed the production of novel and homogeneously dispersed soft-nanocomposites. While the nanostructured carbon materials produced by simple mixing do not homogeneously disperse into a preformed gel, C60- and MWC…
The structural and hydrogen/deuterium desorption properties of AlH3/AlD3 were investigated by Raman spectroscopy, high-intensity X-ray/neutron diffraction, and thermogravimetric analysis. The latter revealed that more than 9.6 mass% of hydrogen/18.1 mass% of deuterium desorbs from AlH3/AlD3, respectively. The presence…
We developed a new method for fabricating reduced graphene oxide (RGO)/Fe-oxide structures from graphene oxide (GO), and for the simultaneous vertical alignment of the RGOs using a single-step process that involves a magnetic field and the fixation of the aligned structures by means of direct evaporation of the films.
Some novel Schiff bases have been derived using aromatic aldehydes and aromatic amine in ethanol under acidic conditions. The geometry of these Schiff bases was established using various spectroscopic methods like infrared (IR), nuclear magnetic resonance (NMR) and mass spectrometry. The conductivity studies reveal th…
A simple and easy method was developed for preparation of large-scale free-standing mesoporous protein thin films through a filtration technique by using ultrathin metal hydroxide nanostrands as frames and pore templates. Composite nanofibrous dispersions of nanostrands and proteins were formed by assembling negativel…
We describe the formation of BaTiO3 superstructures from precursor nanoparticles and the use of ferroelectric properties to trigger a hierarchical growth mechanism. Without specific treatment, the precursor nanoparticles comprise of ferroelectric domains that are oriented randomly (domains of the same spontaneous pola…
We show, using α-glycine in an equi-volume methanol/water mixture as example, that the influence of solvent and solvent mixtures on crystal habits can be predicted by using Extended Interface Structure Analysis (EISA), a hybrid multiscale method based on molecular simulations and theoretical thermodynamic analysis of…
Integrated Coal Gasification Fuel Cell Combined Cycle (IGFC) is expected to be the most efficient power generation system in coal fired power generation systems [1,2]. The Japanese project of the Strategic Technical Platform for Clean Coal Technology (STEP-CCT) aims a target efficiency of 65% (HHV) with exergy recuper…
Instead of metal oxides or alloys, a novel co-assembled conducting polymer, polyaniline–poly(pyrrole), was employed and demonstrated significantly enhanced ethanol oxidation catalytic activities and stability on Pt-based catalysts, indicating a potential practical application in direct ethanol fuel cells with low cost…
Elastic and damping properties of AZ31 magnesium alloy sheet processed by high-temperature rolling were investigated. The specimen rolled at high temperature (798 K) exhibited the significant low basal texture intensity and the wide spread of the basal pole toward the RD and TD, compared with the specimen rolled at 57…
The microdomain structure of polystyrene-polymethylmethacrylate block copolymer (PS-b-PMMA) can be directed by a photochemically attached polymer surface layer. The photochemical attachment of the neutralization polymer on the silicon surface is a convenient and effective technique for interfacial energy control to pr…
We present a simple and straightforward method for creating a hierarchical structure in which the nanoscale roughness is derived from a microstructure. This hierarchical structure is at the backbone of almost all biomimetic functions. A liquid blend of a photocurable prepolymer and a functionalized polysiloxane is mou…
The explorative coordination chemistry of the bridging ligand TTF-PPB is presented. Its strong binding ability to Co(II) and then to Ni(II) or Cu(II) in the presence of hexafluoroacetylacetonate (hfac(-)), forming new mono- and dinuclear complexes 1-3, is described. X-ray crystallographic studies have been conducted i…
The high sensitivity of graphene to the adsorption/desorption of gas molecule, is at the very beginning of its exploitation. This sensitivity relies on the two-dimensional nature of graphene allowing a total exposure of all its atoms to the adsorbing gas molecules, thus providing the greatest sensor area per unit volu…
