Tensile dynamic mechanical analysis at 1 Hz was used to characterize the solid rheological properties of β-PVDF films. Both the elastic and loss moduli and the specific damping capacity were monitored against temperature, allowing the study of the effect of anisotropy upon the viscoelastic properties of the films. The…
Using electromagnetic levitation in combination with the oscillating drop technique and drop calorimeter method, the surface tensions and specific heats of undercooled liquid Co-10 wt% Mo, Co-26.3 wt% Mo, and Co-37.6 wt% Mo alloys were measured. The containerless state during levitation produces substantial undercooli…
Microstructural evolution during transient liquid phase (TLP) bonding of nitrogen containing duplex stainless steel UNS S31803 has been investigated. In order to evaluate mechanical property of joint, tensile strength test was carried out at room temperature. TLP bonding was conducted at the temperature range 1283–135…
The transient liquid phase (TLP) bonding process of Ni using a Ni–11 mass%P binary filler metal was simulated by using both a phase-field model (PFM) and a moving boundary model (MBM). The dissolution of the base metal and isothermal solidification behavior during the TLP bonding process were simulated, and the result…
The atomic layer deposition (ALD) method based on surface-saturating gas-solid reactions was applied to grow vanadia species on highly dispersed titania/silica supports with from submono- to above monolayer levels of titania. The physicochemical properties of the V2O5/TiO2/SiO2 catalysts were examined with N2 adsorpti…
Abstract We present a detailed density functional theory‐based investigation on the geometry and electronic structure of the [Co 4 (hmp) 4 (MeOH) 4 Cl 4 ] molecule. It is experimentally found to behave as a molecular magnet. The all‐electron electronic structure calculations and geometry optimization of the 88‐atom mo…
Theoretical and experimental results on the limitation of pulsed radiation in the spectral range 3.8–10.6 µm in vanadium dioxide films are presented. The effect of the film structure on the shape of the temperature hysteresis loop is studied. The film thickness and the structure of an interferometer with a vanadium di…
The relationship between primary and secondary recrystallization texture, and the improvement of primary texture on grain oriented silicon steel was examined. The specimens were prepared by using different C content and different hot rolling conditions in the acquired inhibitor method. Higher reduction of the later pa…
The meso-disubstituted dipyrrolide ligand (L) has promoted the formation of a unique tetranuclear iron(II) compound that contains both diazaferrocenyl and distorted-tetrahedral iron centres.
This study examined the effect of medium density fiberboard (MDF) density and sorption state on the sorption isotherms and the effect of panel moisture content and density on the effective water conductivity and diffusion coefficient of MDF panels. A total of 39 laboratory-made MDF panels with dimensions 650 mm X 650…
Flame spray pyrolysis has been utilized in order to improve the photoluminescence (PL) intensity of blue-emitting phosphor particles for light emitting diode applications. When phosphor particles were prepared by conventional spray pyrolysis, the PL intensity was much lower than that of commercial phosphor particles.…
Templated sol–gel encapsulation of surfactant-stabilised micelles containing metal precursor(s) with ultra-thin porous silica coating allows solvent extraction of organic based stabiliser from the composites in colloidal state hence a new method of preparing supported alloy catalysts using the inorganic silica-stabili…
New crystal of glycine with lithium nitrate [(NN + 3CH 2 COO - )LiNO 3 ; GLiN] was discovered. It belongs to the space group Pl of the triclinic system. Its structure is different from that of the glycine-NaNO 3 crystal (GNaN). The Li 2 O 6 units can be distinguished in the GLiN crystal. They have a shape of two symme…
我々は、アルカリセルラーゼ、アルカリα-アミラーゼ、アルカリプロテアーゼの大規模生産を行い、衣料用コンパクト洗剤や漂白剤に利用してきた。初期に使用されてきた洗剤用酵素は、特に自動食器洗浄機中で使用される際には、酸化剤やキレート剤等の洗剤組成物によって簡単に失活し、また、熱に不安定であることが問題であった。我々は、好アルカリ性細菌 Bacillus sp. KSM-1378株が生産するアルカリ液化型α-アミラーゼAmyK(以前LAMYとして報告した)を見い出した。AmyKは今まで報告された他の産業用アミラーゼに比べ、アルカリpHで高い活性を示し、種々の界面活性剤に対して耐性を示した。しかしながら、AmyKはBacillus lich…
Hot dip Zn-Mg galvanized steel sheet having excellent corrosion resistance was developed aiming to elongate the life time of hot-dip galvanized steel sheet. This pre-coated steel sheet also revealed the customers cost down due to the reduction of post-dip galvanized process. It has excellent corrosion performance in v…
The atomic and electronic structures of the Al Σ=9 tilt grain boundary with segregated impurity atoms have been calculated by the first-principles pseudopotential method based on the local density functional theory. Effects of impurities of group I (Na), group II (Ca), group IV (Si) and group VI (S) have been examined…
The morphology, chemical composition, and crystal structure of aluminum anodized films formed in 85°C aqueous ammonium adipate electrolyte at various forming voltages (20-200 V) were investigated. The relationship between the microstructure and the electrochemical behavior of the anodized oxide film was also explored.…
Collagen is the most abundant protein among vertebrates and occurs in virtually all multicellular animals. Collagen molecules are classified into 21 different types and differ in their sequence, weight, structure, and function, but they can be broadly subdivided into families. Type IV, VI, VIII, X, and dogfish egg cas…
In this study, the use of thin Si interlayers (35–150 nm) for promoting diamond deposition onto steel is investigated. The diamond films are deposited by hot filament CVD onto AISI type 316 stainless and high-speed steels. Single stage deposition at substrate temperatures ranging from as low as 475 to 750 °C is found…
Amorphous selenium is one of the most promising candidates as photoconducting material for future imaging devices. It can exhibit ultra-high photosensitivity by using avalanche multiplication inside the solid. However, the requirement of high vacuum by the electron emitters prevents amorphous selenium from being a rea…
