Abstract The dynamic fracture toughness of TA15ELI alloy with two types of microstructures was studied by instrumented impact test. Charpy specimens with both the 0.2 mm U‐notch and the a/W = 0.2 pre‐crack were adopted to compare notch sensitivity in the two microstructures. The result shows that the specimen with Wid…
The time–temperature-transformation (TTT) diagram of amorphous alloys is important for the applications of alloys. However, measurement for it by the conventional method is a time-consuming process. We propose a high-throughput measurement method for compiling TTT diagrams of thin film amorphous alloys. For this metho…
This paper describes a new strategy for fabricating a gold (Au) island film based on a silver (Ag) aerosol surface activation onto a porous polytetrafluoroethylene (PTFE) substrate, followed by electroless deposition (ELD). Spark produced Ag aerosol nanoparticles ( in diameter) were physically captured ( PTFE in activ…
Ortho-type UP resin is reinforced with long abaca and short bagasse fibers to produce a novel type of natural fiber-reinforced (NFR) hybrid composite material that is environment-friendly, has a long service life, possesses the properties of both long and short FRP’s, and has also acquired the advantages of utilizing…
Organoclay (Cloisite 30B)-reinforced polyetherimide (PEI) and pristine nanoclay (K10)-reinforced PEI nanocomposite films were made by solution casting process with 0.5, 1.0, 2.0, and 3.0 wt% values of nanoclay. Scanning electron micrographs showed that Cloisite 30B was uniformly dispersed in PEI/Cloisite 30B nanocompo…
Abstract A new manganese(II) complex [Mn3(bidc)2(C2O4)(H2O)10]n (1) (bidc = benzimidazole‐5,6‐dicarboxylate) was synthesized and characterized by X‐ray crystallography. X‐ray diffraction shows that complex 1 has a neutral, one‐dimensional (1D) brick wall chain structure. With the intramolecular and intermolecular hydr…
A new kind of polyaniline/polytetrafluoroethylene (PANI/PTFE) composite membrane has been successfully prepared by in situ deposition of PANI onto PTFE membranes during the aniline's dispersion polymerization. The PTFE membrane was plasma treated before the aniline polymerization; the induced alteration of morphology…
We calculate the current-voltage characteristic of metallic nanotubes lying on a substrate at high bias voltage showing that a bottleneck exists for short nanotubes in contrast to large ones. We attribute this to a redistribution of lower-lying acoustic phonons caused by phonon-phonon scattering with hot optical phono…
Nanostructured functional oxides have attracted a great research interest as important constituents of electrochemical devices. A new type of porous nickel oxide and ceria (NiO- Ce 0.9 Gd 0.1 O 1.95 , a typical anode material for solid oxide fuel cells) nanoparticles-structured-in-nanowire was synthesized. The sizes o…
(E,E)-1-[2-(4-Nitrophenyl)ethenyl]-4-[2-(2,4-dimethoxyphenyl)ethenyl]benzene was characterised by X-ray diffraction and shown to be dynamically disordered at room temperature. The structure was re-determined over a range of temperatures to infer the thermodynamic parameters related to this disorder. A phase transition…
Abstract The thermomechanical coupling simulation of the isothermal equal channel angular pressing (ECAP) of Ti‐6Al‐4V alloy was conducted. The effect of processing parameters, ECAP pass number and the residual billet on the effective strain, stress and temperature distribution was investigated. Based on the coupling…
Microscopical, differential scanning colorimetry (DSC), and X-ray structural investigations of solution crystallized carbon nanotube (CNT) composites with linear polyethylene (LPE), isotactic polypropylene (iPP), polybutene-1 (PB-1), and nylon 6 (PA6) disclosed varying degrees of surface interaction and nucleation eff…
Abstract A photosensitizer‐Eosin and a reductant‐Fructose have been used in the photogalvanic cell for photochemical conversion of solar energy into electrical energy. The generated photopotential and photocurrent are 848.0 mV and 240.0 μA, respectively. The maximum power of the cell is 203.52 μW whereas the observed…
The relaxation dynamics of 5,10,15,20-tetrakis(4-hydroxyphenyl)-porphyrin (p-THPP) in tetrahydrofuran (THF) and encapsulated within the human serum albumin (HSA) protein in water solution was investigated. The protein environment affects the B→Q(y) and Q(x)→Q(y) transition dynamics (from 80 and 140-200 fs in THF to 50…
Two new compounds of disphosphopentamolybdate (VI), (C6H18N2)2[H2P2Mo5O23] · 2(H2O) (1) and (C6H18N2)4.5H3[P2Mo5O23]2 · 6(H2O) (2), have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the triclinic space group P 1 with a = 11.0863(9) Å,…
Abstract The microstructure, in‐plane anisotropy, and magnetic properties of Fe‐Ga thin films were investigated by X‐ray diffraction analysis, vibrating sample magnetometer, and capacitive cantilever method. The in‐plane induced anisotropy is well formed by the applied magnetic field during sputtering, and the anisotr…
We studied the adsorption of neutral M, charged M, and M 2 dimers (M = Cu, Ag, Au) on the pristine single-walled carbon nanotubes (SWNTs) as well as on the Stone−Wales and vacancy sites by means of the B3LYP/6-31G (d,p) hybrid density functional method. Our results for neutral metal atoms on the pristine and defective…
We have studied two surfaces of a new Al–Pd–Zn approximant using mass spectrometry, X-ray photoemission spectroscopy (XPS) and scanning tunneling microscopy (STM). Zn is bonded weakly in this approximant, perhaps as weakly as in elemental Zn. This is based upon three observations: (1) the low vapor pressure of Zn abov…
Transparent hafnia films containing glycolic acid or lactic acid as a hydroxy acid were successfully prepared in aqueous solutions. The films showed not only hydrophobicity but also high adhesive force to water droplets. The contact angles of the water droplets were 90–94°. Droplets on the surface maintained their sha…
The electronic structures of bcc Np, fcc Pu, Am, and Cm pure metals under pressure have been investigated employing the LDA + U method with spin-orbit coupling (LDA + U + SO). The magnetic state of the actinide ions was analyzed in both LS and jj coupling schemes to reveal the applicability of corresponding coupling b…
