The Effect of Overheating Treatment on the Crystal Orientation of TbDyFe Alloy
The effect of overheating treatment on the crystal orientation of the Tb0.27Dy0.73Fe1.9 alloy was investigated. The results indicated that different overheating treatment conditions could obtain different crystal orientation. It means that overheating treatment affects the process of Tb0.27Dy0.73Fe1.9 solidification.…
A thermodynamic model for determination of the vibrational temperature in non thermal plasmas
A gaseous plasma in a non-local thermodynamic equilibrium (NLTE) can be characterized by the thermal disequilibrium Te ≠ Tex ≠ Tvib ≠ Trot ≠ Th, where Te and Th are respectively the translational temperatures respectively for the free electrons and heavy species, and Tex, Tvib, Trot are the internal temperatures respe…
Study for MDS properties of pressured CO2 to supercritical state and DC breakdown mechanism
Summary form only given. The generation of DC discharge in supercritical carbon dioxide using a point-plane electrode with the gap distance tens of mircometer is studied experimentally. The results reveal a strange phenomenon that there is a slightly drop of breakdown voltages in vicinity of supercritical phase. It is…
Imaging and characterization of femtosecond surface plasmon wave packets on a silver film
Irradiations of nano-structured metal films by ultrashort laser pulses excite surface plasmon wave packets, which propagate along the metal-dielectric interface for tens of femtoseconds. Recently developed novel time-resolved microscopic methods enable to take movies of the evolutions of them. We show photoemission el…
P2‐143: Intracellular seeded aggregation and cytotoxic model of TDP‐43
TAR-DNA binding protein of 43 kDa (TDP-43) is the major component protein of ubiquitin-positive inclusions observed in brains of patients with frontotemporal lobar degeneration (FTLD-U) and amyotrophic lateral sclerosis (ALS). Here we report the establishment of seeded TDP-43 aggregation model using cultured SH-SY5Y c…
Tailor-made domain structures on the x-face and y-face of LiNbO3 crystals
Domains with a width of a few microns are engineered in lithium niobate crystals by irradiating the surface with strongly absorbed UV light. The fact that the UV light can not only write but also erase domains enables on-demand geometries of the domain features.
The computer simulation research on evolution of solidification microstructure
Phase-field method is the effective method to simulate microstructure as a kind of numerical computer simulation technology. On the basis of the free energy functional, the anisotropy is introduced into the phase-field model which applied to the solidification process, and the side-Branch competitive growth, ripen and…
Synthesis, Characterization and Flame Retardancy of Two Novels Amino Phosphate
Two phosphorus-containing flame retardant (FR) were synthesized and incorporated in the backbone of polyamide 6(PA6) by polymerization. The structure and spectroscopic data of these flame retardant were determined by Fourier Transform Infrared Spectroscopy (FTIR) and Elemental analysis. Flame-retardancy and thermal pr…
3D non-destructive grain orientation mapping of polycrystalline materials using 3D-XRD and TEM

Thermal Stability of a Novel Polytriazoleimide
A new polytriazoleimide (PTAI) was prepared from 1,2,3-triazole-containing diamine and 4,4’-(hexafluoroisopropylidene) diphthalic anhydride by polycondensation. The thermal stability was investigated. The PTAI was pyrolyzed at 400 °C and 750 °Cseparately and the pyrolysis was traced by the Py/GC/MS combined technique.…

Effect of Fibrinolytic Compound GDG on Crystal Structure of Lysozyme
Lysozyme was extensively studied as a model of protein crystallization, we identified that 15 mg/ml lysozyme, 0.1 M sodium acetate buffer containing 5% (w/v) sodium chloride and 0.02% (w/v) sodium azide, pH 5.2, crystal nucleus were less and crystals could reach a certain size. Basic on GDG effected conformation of en…
Preparation and Characterization of Polyacrylonitrile-Based Fluorescence Probe for Sensing Solution Structure Change
A novel polyacrylonitrile (PAN)-based fluorescence probe was prepared by chemically combining the aminoanthraquinone as a fluorescent group with the PAN chains. It is found that the -C≡N group in PAN chains can affect the photolysis of anthraquinone groups. The results show that the conformational state and aggregati…
Study on the Mechanical Property of the Spun Silk and T-400 Interlaced Fabric with Different Weaves
T-400 is an elastic fiber developed by Dupont. It was commended as one of the best developing prospect chemical fiber in the 21 century. In this paper, the mechanical property of spun silk/T-400 interlaced fabric with different weave was studied. The drawing, peaking, bending and abrasive characteristics of the spun s…
Carbon nanotube pastes for field emission prepared by adding metallic and oxide nanoparticle fillers
The CNT paste, to be screen-printed for field emission applications, should satisfy many stringent requirements such as CNT dispersion, surface uniformity, paste adhesion to a substrate, CNT adhesion in the paste, low outgassing rate in vacuum, printability, long shelf lifetime, etc. In our previous study, the CNT pas…
Evaluation of Optical Properties for Nanocrystal Si Dot Layers Fabricated by CVD as a Function of Size Reduction
Raman spectroscopy and photoluminescence were performed in order to understand the optical properties of nanocrystal Si in relation to quantum confinement effects. The nanocrystal Si (nc-Si) dots in the SiO2 layer were fabricated by the H2 plasma treatment and chemical vapour deposition followed by the oxidation of th…

Intramolecular Nucleophilic Substitution in the Hydrolysis of Bis(4-Nitrophenyl) Phosphate Ester Catalyzed by the Metallomicelle
A macro-cyclic Schiff base ligand and the corresponding Cu (II) and Ni (II) complexes were synthesized and characterized. And the catalytic efficiency of the metallomicelles made of these complexes and noninonic micelle Brij35, as mimetic hydrolytic metalloenzyme, was investigated in the catalytic hydrolysis of bis(p-…
