A new method has been developed to fabricate multilayer films by superimposing free-standing films and the resulting film was utilized as the barrier coating to control the drug release. First, the poly(lactic acid) (PLA) free-standing film was prepared by using polyvinyl alcohol (PVA) as a sacrificial layer. Then the…
A method to measure the refractive index of the ceramic layer of thermal barrier coating (TBC), based on the intensity ratio of the reflections of terahertz waves from the ceramic surface and a reference metal plate, is proposed. The method uses a variable aperture to change the relative proportions of specular reflec…
Electrically driven high-speed light emitters based on compound semiconductors are widely used in the areas of optical communication, time-resolved spectroscopy, etc. However, because of their large footprints, the low crystal-linity of the compound semiconductors grown directly on Si wafers, these emitters face signi…
木粉を基材としたポリアリルアミン型貴金属吸着剤（CPP-GP吸着剤）を合成し，金めっき排液から金の回収を試みた．このCPP-GP吸着剤は，金のみならずパラジウムに対しても選択的な吸着特性を示した．めっき排液では，pH 4～6の範囲で吸着効率が高かった．これは実際のめっき排液の場合，pHの調製が不要となり回収処理のプロセスが容易となることが考えられた．夾雑物の多いめっき排液での金吸着容量は吸着剤質量に対して8.4％ だった．X線光電子分光装置（XPS）及び昇温脱離ガス分析装置（TDS）を用いて，金吸着前後のCPP-GP吸着剤を測定することで，シアノ金の形態で結合していることが明らかになった．めっき工場にてCPP-GP吸着剤を用いた金…

In this study, case-hardened steel rollers with an effective case-hardened depth of 2 mm were fatigue-tested using a roller testing machine in order to elucidate their rolling contact fatigue life. They were made of three kinds of steels. These experimental results were compared with the results of the case-hardened s…
It is a known fact that fibers are usually added to cementitious composites (concrete and mortar) in order to improve some of their physical-mechanical properties, such as: tensile and flexural strength, impact resistance, shrinkage, freeze-thaw resistance, durability, etc. On the other hand, improvement of deformatio…
In a chemical surface modification, effects of modified conditions on adhesive force were investigated. As test samples, propyl-modified plates were prepared by 36 different modified conditions on Si plates. The surface free energy and surface roughness of the modified plates were measured. Furthermore, adhesive force…

Mesoporous titania is a cheap, non-toxic photocatalyst that can play an important role in for example hydrogen generation from water splitting, -air and water purification. Furthermore, porous titania is already used as a catalyst in different industrial processes, such as the recovery of elemental sulfur from waste g…
采用溶胶—碳热法制备LiFe1-xCoxPO4/C（x=0,0.05,0.1）复合正极材料。研究发现：钴离子掺杂不改变磷酸铁锂的晶体结构特征,在LiFePO4/C复合材料掺杂金属离子后,材料的电化学性能得到改善。原因是掺杂可以使材料内部产生部分缺陷,缺陷的产生有利于提高材料的导电性,从而提高电化学性能。LiFe0.95Co0.05PO4/C具有最好的电化学性能,循环中最高的放电容量为152.3mAh/g,50次循环后放电容量为146.4mAh/g,容量保持率为96.2%。

Plasmonics in the deep-UV spectral range (λ=200–300nm) has been eagerly studied in the recent decade. In this range, Al has been considered as the only reliable, efficient metal supporting surface plasmon resonances (SPRs) while SPRs can’t occur in Au and Ag[1]. In the study that will be presented in this talk, we wil…
Natural clay mineral, allophane, was tried to be used for removal of cesium ion from aqueous solution. The removal performance of allophane was evaluated by atomic absorption spectrometry in batch test and flow test compared to that of the other clay minerals, such as zeolite, montmorillonite, and kaolinite. The adsor…
Application of the Debye model to the temperature dependence of atomic mean square displacements determined by X-ray diffraction provides individual knowledge of dynamic and static natures of atomic displacements, together with characteristic values of crystals such as Debye temperature and one particle potential coef…
