Cet article présent des travaux qui visent a la valorisation de déchets issus de l’industrie de transformation de l’olive ainsi que du papier (cellulose). L’objectif est la création et la caractérisation d’un matériau isolant à base de grignon et de cellulose. Différentes compositions cellulose/grignon ont été étudiée…
The purpose of the present work is to investigate the effects of helium plasma treatment on tensile deformation of nano-SiO2 sol-gel coating T300 carbon fiber and provide a new concept for the nano-structural interphase between fiber surface and nano-coating. The tensile test results show that the activation volumes o…
高分子融体からの結晶化過程は，一次核生成と結晶成長という二つの主な機構からなっている．アイソタクチックポリプロピレン(iPP)の結晶構造，結晶成長速度およびモルフォロジーについては，多くの研究結果が報告されている．しかし，一次核発生速度の結晶化温度依存性を詳しく報告した論文は少ない．iPP の核発生速度は非常に速いため，従来高温域の極めて狭い結晶化温度範囲でしか実測することができなかったが，測定法を改善することにより，広い結晶化温度範囲での測定を可能にした．本報では，iPP の α 型，β 型(β 核剤添加)の核発生速度(I)および飽和核数(Ns)を広い結晶化温度範囲で実測し，それぞれの結晶型の結晶化温度依存性について考察を行った…
Sodium octanoate CH3-(CH2)6-COONa was found to be one of the straight chain aliphatic carboxylates that show good inhibition characteristics towards mild steel. However, as the previously tested concentrations were too high to be applied in the water treatment of secondary circuits, lower concentrations have been inve…

A set of experimental results reported in the literature was analysed by the application of a mathematical model developed previously. The experimental results analysed consist in a set of shape memory polycrystalline samples which was subject to simple uniaxial tension test. The crystalline orientation of several gra…
Natural fibres have received a growing interest from the composite community over the last decade because they offer a low cost and environmentally friendly alternative to conventional reinforcing fibres. Natural fibre reinforced materials are currently used in different domains such as the automotive industry for exa…
The bcc element, Nb, has the interesting and atypical property that it is predicted to fail by ⟨111⟩ {112} shear, rather than by {100} cleavage, when strained to its ideal strength in uniaxial tension. This suggests that pure Nb will not exhibit the classic bcc ductile–brittle transition when fractured at low temperat…
Fracture mechanics/technology is a key science and technology for the design and integrity assessment of the engineering structures. However, the conventional fracture mechanics has mostly targeted a limited size of cracks/defects, say of from several hundred microns to several tens of centimeters. The author and his…
The aim of this study was to fabricate type II collagen fibrils with surface modified by long-chain hyaluronic acid. Monomeric type II collagen was isolated from bovine articular cartilage and reconstituted into collagen fibrils followed by a reaction with EDC (1-Ethyl-3-[3-dimethylaminopropyl] carbodiimide)-activated…
Al2O3/YAG composite powders have been synthesised by reverse strike precipitation. The powders were characterised by DTA/TG simultaneous analysis; the phase evolution was studied by XRD analysis, while the crystallite formation and growth were followed by TEM observations. A fully dense, homogenous material was obtain…
Many examinations concerning the fatigue life reduction for structural materials of nuclear power plants in water simulated LWR coolants had been carried out after the first paper had been recognized in Japan [1, 2]. Based on these results, the method to evaluate the fatigue damage for the materials exposed to the LWR…
The dependences of the Δ E effect and internal friction on the magnetic field have been investigated upon the magnetization and magnetization reversal of some polycrystalline ferromagnetic materials with different properties. It has been shown that for all the materials that have been investigated there is characteris…
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin‐orbital polaron when…
Thin film solar cells made of amorphous or microcrystalline silicon provide renewable energy at the benefits of low material consumption. As a drawback, these materials don’t offer the high carrier mobilities of their crystalline counterpart. Due to low carrier mobilities, increased process times and material consumpt…
The liquid crystal phase diagram of the discotic hard spherocylinder fluid is investigated in Monte Carlo simulations. The study involved the development of an efficient algorithm to compute the shortest distance between two oblate spherocylinder particles. Molecular aspect ratios within L/D = 0.1–0.5 are considered.…
Recently, eco-friendly machining has been drawing attention in manufacturing field. Especially, environmentally conscious cutting process has been developing widely. However, there is few method that achieves low environmental impact in final polishing field. Here, a new polishing method with fixed-abrasives was propo…
Fatigue properties in high cycle and very high cycle fatigue regime of high speed tool steel (0.7C-0.1W-3Mo-2V) were investigated through the experimental results obtained from a cantilever-type rotary bending fatigue test in air at room temperature using hourglass shaped specimens. Two kinds of specimen were processe…

The performance of a solid oxide fuel cell (SOFC) stack system driven by simulated reformate was investigated in this study. CH4 was used as a surrogate fuel for low hydrocarbon components in reformate gas. One of the motivations for this study is to articulate the effects of low hydrocarbons in reformate gas, such as…
