The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) was founded with the aim to promote scientific cooperation in the area of construction materials and structures worldwide. This mission is achieved through collaboration of leading experts in construction prac…
Diatom and calcareous nannofossil biostratigraphy was established for the PlioceneKuwae Formation along the Natsui stratigraphic section, Tainai River, Kitakanbara area in NiigataPrefecture, central Japan. Three useful diatom biohorizons, the FO (first occurrence) ofNeodenticula koizumii; RI (rapid increase) of N. koi…
Emissions of methane to the atmosphere are deemed by many to pose environmental problems. Conversion of methane to carbon dioxide through combustion reduces greenhouse gasses and can provide a source of energy. Catalytic combustion is a viable option for oxidation of lean methane streams. Lean methane mixtures can be…
The effect of ageing in parent phase and martensite stabilization on melt spun Ni50Ti30Hf20 ribbons were investigated by Differential Scanning Calorimetry and X Ray Diffraction. Thermal treatments in parent phase generally shift the martensitic transformation range as far as an equilibrium state is reached. The equili…
Thermal aging embrittlement of newly developed W-alloyed 9%Cr ferritic steel KA-STBA29/KA-STPA29 (ASME T92/P92) was investigated. In order to clarify the controlling factor of embrittlement, Charpy impact tests were carried out, and characterization of precipitates was determined through use of materials that had been…
Optically transparent and homogeneous polymer hybrids of poly(2-methyl-2-oxazoline) (POZO) and vanadium oxide (V2O5) can be prepared by utilizing the hydrogen bonding interactions between the amide groups of POZO and V–OH groups formed in the hydrolysis of vanadium(V) oxytripropoxide (TPVO). POZO acts as a stabilizer…
The end use requirements for standard ASTM F 562 wire for pacing leads present difficult challenges to achieve the desired performance of these permanent implant devices. It will be shown that an optimized process produces a measurable improvement in surface finish and greatly improved fatigue life of wire forms under…
In this study, new organic-inorganic hybrid composites were prepared by means of an in situ sol-gel process. The polymer used as the continuous phase was the metallocene polyethylene-octene elastomer (POE) or the acrylic acid grafted polyethylene- octene elastomer (POE-g-AA). The silica forming the inorganic phase was…
On propose un modèle de comportement prenant en compte les couplages thermomécaniques qui accompagnent le changement de phase dans une éprouvette monocristalline de CuZnAl. Cette modélisation met en avant le rôle capital joué par la diffusion de chaleur dans la propagation de fronts de changement de phase. Les simulat…
Article Continuous filtration and titration apparatus for real time monitoring of polyelectrolyte concentration and cationic demand of a paper furnish was published on January 1, 2003 in the journal Nordic Pulp & Paper Research Journal (volume 18, issue 1).
A new compound [La(NMP) 4 (H 2 O) 4 ][HGeMo 12 O 40 ]·2NMP·3H 2 O (NMP = N -methyl-2-pyrrolidone), 1 , was synthesized and characterized. The compound crystallizes in the monoclinic space group P 2 1 / c with a = 17.3428(4), b = 18.3258(5), c = 23.0387(7) Å, g = 107.088(1)°, V = 6998.9(3) Å 3 and Z = 4. The structure…
In this work we investigated the possibility of using scintillating rare earth Ce3☎, Tb3☎, and Pr3☎ ions to optically activate germanate glass matrices. Glasses were characterised in terms of radiation resistance, UV-VIS transmittance and luminescence spectra. Their radiation induced response was found to be dependent…
This paper is an overview of fundamental studies and large scale achievements of the foam decontamination technique in the frame of a ten years research program conducted in the CEA. Main aspects of foam feature (hydrodynamic, stability, chemical composition) are developped. Industrial applications gave the opportunit…
The three phase transitions at T 1, T 2 and T 3 in CsZnPO 4 crystal have been studied using an X-ray diffraction technique with both bulk and powder crystals. It is found in bulk crystals that all the three phase transitions take place and that two high temperature phase transitions at T 1 and T 2 are fast, while the…
Contrary to the conclusions based on isotropic elasticity, anisotropic elasticity theory predicts that a screw dislocation in the b.c.c. lattice dissociated symmetrically into three 1/6 [111] partial dislocations on {110} planes is stable or metastable. A symmetric dissociation on {112} planes is unstable. For the hig…
The decomposition performance of p-chlorophenol in aqueous solution by combination of ultrasound and ultraviolet light was examined. The decomposition of p-chlorophenol in aqueous solution was a pseudo-first-order reaction. The decomposition rate constant increased with increasing ultrasonic intensity and became lower…
The composition of nitrogen-doped hydrogenated amorphous carbon (a-C : H : N) films grown in a magnetically confined rf plasma-enhanced chemical vapour deposition system has been determined by X-ray photoelectron spectroscopy (XPS) and compared with that determined using a combination of elastic recoil detection analy…
Electrochemical capacitors have been devised using hybrid electrolytes containing either lithium or magnesium salt and high-density graphite (HDG) electrodes. The cells exhibit single-electrode discharge capacitance of 355 μF/cm 2 at 1 mA/cm 2 discharge rate for magnesium-containing ormolytes at 80°C. Typical response…
Issues associated with the development of an alkali metal thermal‐to‐electric conversion (AMTEC) converter model that serves as an effective design tool were investigated. The requirements and performance prediction equations for the model were evaluated, and a modeling methodology was established. It was determined b…
Method of modification of highly oriented pyrolytic graphite (HOPG) is proposed for deposition of biological objects especially DNA for scanning probe microscopy. Atomic force microscopy (AFM) images of DNA on HOPG are compared with those on conventional support — mica. The advantages of HOPG as a substrate for DNA fo…
