Bi 0.98 Nd 0.02 FeO 3 (BNFO) and Ba 0.8 Sr 0.2 TiO 3 (BST) epitaxial films produced by rf cathode sputtering on (001)MgO substrates are studied by means of XRD. The thickness dependences of uniform lattice deformations and linear dislocation density, generated due to epitaxial stress relaxation, are plotted.
The uranium extraction (UREX) process separates uranium, technetium, and a fraction of the iodine from the other components of the irradiated fuel in nitric acid solution. In May 2012, the time, material, and footprint requirements for treatment of 260 L batches of a solution containing 130 g-U/L were evaluated for tw…
The rearrangement of the grain structure of Ni 3 Fe alloy upon an A 1 → L 1 2 phase transition is studied via transmission electron microscopy in combination with the electron backscatter diffraction. It is established that the formation of fresh grain boundaries of general and special types occurs, with the proportio…
The technology of drawing with shear is developed. It allows increasing\ntechnological plasticity of low carbon steel without heat treatment. It is\nfound that the use of experimental technology can improve mechanical properties\nof wire samples with the diameter reduced during drawing: the relative\nreduction of the…
Abstract: The influence of annealing treatment on the interface-correlated microstructural evolution and subsequent mechanical properties of an Al1050/AZ31B clad sheet was systematically investigated. A scanning electron microscope with an attached energy dispersive spectroscopy revealed that diffusive layer consisted…
Resonans Plasmon Permukaan Setempat (LSPR) adalah satu fenomena optik hasil interaksi elektron bebas dengan gelombang elektromagnet cahaya pada permukaan nonozarah logam. Sifat LSPR nanozarah logam yang sangat sensitif kepada sifat dielektrik medium persekitaran menyebabkan fenomena ini digunakan secara meluas dalam p…
Abstract : Equiatomic powder mixtures of Al and the early transition metals in Groups IV and V (i.e., titanium [Ti], zirconium [Zr], and hafnium [Hf]; and vanadium [V], niobium [Nb], and tantalum [Ta]) were prepared by high-energy mechanical alloying. Blends were subjected to microscopy and differential thermal analys…
tEfficient hydrogen storage with a high density under near-ambient temperature remains a key techni-cal obstacle for a hydrogen economy. Here we demonstrate the enhanced room-temperature hydrogenstorage in super-activated carbon materials, which were prepared by carbon dioxide activation of tem-plated porous carbons.…
This quarterly report covers the following points: A fully three-dimensional smeared cracking model has been implemented and tested in BISON; DAKOTA-BISON was used to study the parameters that govern heat transfer across the fuel-cladding; Calculations of grain boundary mobility in UO2 have been extended to high tempe…
Agarose gel/gold nanoparticles hybrid was prepared by adding gold nanoparticles to preformed agarose gel. Naniocomposite structures and properties were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and UV-Vis-NIR absorption spectroscopy. Experimental data indicated a unif…

OBJECTIVE: This study is conducted to explore new methods to perform surface biomodification of titanium implants and improve osteogenic efficiency. METHODS: An RGD peptide and chitosan (CS) were combined by acylation reaction, forming RGD-CS. An RGD-CS/pDNA complex was subsequently prepared using a complex coacervati…
PUPPOSE: To investigate Candida albicans and Streptococcus mutans adhesion to 3 polyurethane composites [pure polyurethane (PU), 1% polyphosphazene-containing polyurethane (PZS-1%) and 5% polyphosphazene-containing polyurethane (PZS-5%)]. METHODS: Two kinds of microorganism suspension were incubated with the specimens…
Eu-Ag co-doped borate glasses were prepared by the high temperature solid method in the present work. Absorption and emission spectra were employed to investigate the precipitation of Ag nanoparticles, which is influenced by the network form B2O3 and the co-doped Eu ions. It was found in the absorption spectra of Eu-A…
The influence of different additives on the mechanical properties of hydroxypropyl methylcellulose (HPMC) free films was studied using tensile testing. Free films were prepared using the cast method and sliced into bands, and their tensile strength and maximal elongation at break was measured. The results showed that…
In the present paper, nanocrystalline silicon thin films on glass substrates were prepared by rapid thermal annealing (RTA) of RF magnetron sputtered system and alpha-Si/Al films at a low temperature in Nz atmosphere. Optical metallographic microscope, confocal optical microscopy, X-ray diffractometer, Raman scatterin…
To study the effect of physiological conditions on spidroins, we analyzed NTR1SR2CT module secondary structure, aggregation and silk-formation influenced by different salts (in different concentration intervals). According to the full-length Araneus ventricosus MiSp sequence, NTR1SR2CT module was constructed and expre…
对硫化叶菌病毒（Sulfolobus virus）STSV2脱氧尿苷焦磷酸酶（dUTPase）基因进行克隆表达，并分析其酶学特征. 根据STSV2的dUTPase基因序列设计特异性引物，以病毒STSV2 DNA为模板进行PCR扩增，将产物克隆至原核表达载体pET32a(+)中，然后，将其转化至Escherichia coli BL21(DE3)进行dUTPase的IPTG诱导表达及纯化，通过SDS-PAGE检测其大小，并测定其酶学活性. 结果表明，诱导表达的重组dUTPase蛋白分子量（Mr）约为38 × 103（含pET32a(+)自带的助溶标签），重组dUTPase在Mg2+存在的情况下能特异性催化dUTP生成dUMP和PPi…
