Five new heteroleptic lanthanide(III) phenolate compounds have been synthesised in high yield, four via a transamination reaction between Ln(N(SiMe(3))2)3 and two equivalents of the phenol, HOC(6)H(2)(2,4-Bu(t))-6-CH(2)N(Me)CH(2)CH(2)NMe(2) [corrected] (LH) in thf {L(2)LnN(SiMe(3))2 where Ln = La (1); Nd (2); Sm (3);…
Careful control of surface chemistry results in strong surface enhanced resonance Raman scattering from dye-labelled oligonucleotides assembled on nanostructured gold surfaces, releasing their potential as reliable enhancing surfaces.
A program to develop new methods to measure the fracture strength of the chemical vapor deposition SiC coatings in nuclear fuel particles has been carried out. Internal pressurization and crush test techniques were developed and applied to prototype‐sized tubular and hemispherical shell specimens. The fracture strengt…
A new SOFC anode material based upon oxygen excess perovskite related phases has been synthesised. The material shows better electrochemical performance than other alternative new anodes and comparable performance to the state-of-art of the electrodes, Ni-YSZ cermets, under pure hydrogen. Furthermore, this material sh…
A new series of N3,O-mixed donor tripods was prepared for luminescent Eu3+ complexes, in which the soft quinoline nitrogen, tertiary amine nitrogen, and hard amide oxygen donors were cooperatively involved. The mixed donor tripods formed more stable 1 : 1 complexes with Eu(NO3)3, La(NO3)3 and Tb(NO3)3 than the corresp…
Radioactive In111 atoms implanted into zinc oxide (ZnO) single crystals occupy substitutional Zn lattice sites after annealing to 700°C. The respective photoluminescence (PL) spectra of the samples were monitored while the donor In decayed into stable and isolectronic Cd. The commonly labeled PL-I9 line could be clear…
We propose to use a neutral electrolyte based on an aqueous solution of NaCl instead of commonly used aggressive acids or alkaline electrolytes for the purpose of electrochemical nanostructuring of GaAs and CdSe substrates. It is shown that the process of material porosification can be controlled by the conditions of…
Effects of microstructures on the creep and corrosion properties were investigated in the Mg-8Al alloys with addition of the rare earth elements (La-rich Mischmetal, RE). The addition of RE to Mg-8Al alloy may form a stable intermetallic phase, Al11RE3 at elevated temperature, and suppress the β phase (Mg17Al12) with…
Three naphthalene-modified cyclodextrins (CDs) 3–5 were synthesized as supramolecular chiral photosensitizing hosts for enantiodifferentiating photoisomerization of (Z,Z)-1,3-cyclooctadiene (1ZZ) to its E,Z-isomer (1EZ). In aqueous methanolic solutions, β-CD-based sensitizer 4 binds 1ZZ in its chiral cavity much more…
The syntheses of [FeL][BF(4)](2).H(2)O, [FeL][ClO(4)](2).H(2)O, [FeL][NO(3)](2).CH(3)NO(2) and [FeL][CF(3)SO(3)](2) (L = tris(4-{pyrazol-3-yl}-3-aza-3-butenyl)amine) are described. The isostructural BF(4)(-) and ClO(4)(-) salts are high-spin between 5-300 K, while the other two compounds are high-spin at room temperat…
The open-circuit potential of the AZ31 alloy in solution shifts toward less negative values, showing several falls with steady-state value in the range from to (saturated calomel electrode), more positive than the initial potential. The formed film exhibits a superior corrosion resistance. X-ray photoelectron spectros…
BACKGROUND: Gadolinium chelates are relatively safe contrast media used in MRI. Immediate severe adverse effects are exceptionally rare and mostly concern mild anaphylactoid reactions. We report a case of anaphylaxis to gadobenate dimeglumine (Gd-BOPTA, Multihance), a gadolinium-based contrast agent. METHODS: A 32-yea…
Phase change memory (PCM) research has largely focused on bulk properties to evaluate cell efficiency. Now both electrical and thermal interface resistances are characterized and shown to be critical for understanding power in a novel damascene-GST cell. Interfaces reduce reset power 20% and reset current 40% and allo…
Spectroscopic data on high-Z materials for impurity diagnostics are important due to its possible use as a plasma facing component in the next generation fusion device. For this purpose molybdenum and tungsten are injected by an impurity pellet injector into the large helical device (LHD) plasmas. Emissions from such…
This study examines the feasibility of co-electrospinning vapor grown carbon nanofibers (VGNF) within thermoplastic elastomer. The reinforcement effect was studied. The diameter of the thermoplastic elastomer was found to range from 0.5 to 3 μm. The mechanical properties of the electrospun fibrous structure were found…
The formation of polypyrrole (PPy) nanowires containing highly dispersed Pt nanoclusters composite was synthesized on glassy carbon electrode (GCE) utilizing cyclic voltammetry (CV) method. Metallic Pt clusters were dispersed in electrically conducting PPy nanowires in order to achieve multielectron-transfer processes…

Pyrolysis experiments of n-hexane were performed and the product distribution and fuel consumption were measured as a function of temperature. The experimental temperatures ranged from 550-675 degrees C, with a pressure of approximately 1 atm, and residence times of approximately 5 s. N-Hexane was used as a model comp…
Shape memory and superelastic capabilities coupled with good biocompatibility give Nitinol the ability to provide functionality seldom possible with traditional engineering alloys. In this study the effect of heat treatments of 300 ∼ 550°C for 2 ∼ 180 minutes on Ti-50.8%Ni (at.%) wire of 30% and 50% cold work was inve…
The Idaho National Laboratory is conducting moderate strain rate (5 to 200 per second) research on stainless steel materials in support of the Department of Energy’s National Spent Nuclear Fuel Program. For this research, strain rate effects are characterized by comparison to quasi-static tensile test results. Conside…
