Recently, the effect of textured surface facing narrow gap, where gases cannot be treated as continuum fluid even at atmospheric pressure, on the properties of air bearings is focused on. For example, Nakamori et al. reported that the friction between a dimpled surface, which is fabricated by partial polishing of diam…
鋼構造物のほとんどは熱切断された部材を溶接により順次組み合わせることにより製作される。したがってこうした溶接構造物の変形を抑え十分な寸法精度を確保するためには、切断から歪取までの各段階における変形を予測する技術が必要となる。本研究では、固有ひずみの概念と部材間の結合状態を表現する界面要素を用いた溶接組立変形シミュレーション法を開発した。
In the Polymer electrolyte membrane fuel cell (PEFC) cathode catalyst layer, the structure of ionomer with which the catalyst is covered is very important on the point of transferring protons to the catalytic surface and oxygen permeation to the surface. But the mechanism of oxygen permeation through an ionomer was no…
Tissue engineering is an alternative approach for the preparation of small-diameter (4〜6 mm) vascular grafts due to the potential to control thrombosis, anastomotic cellular hyperplasia and matrix production. It is very important for tissue-engineered blood vessels (TEBVs) to be cultured under mechanical stimulations,…
Because the operation of a passive type polymer electrolyte fuel cell (passive type PEFC) is accompanied with complex phenomena such as an electrochemical reaction, heat and flow, it is hard to obtain an appropriate orientation for the improved design. Numerical analysis is conducted for the purpose of obtaining the p…
采用水热法制备Ag掺杂量不同的Ag/TiO2纳米复合材料,通过原位聚合法制备PANI/Ag-TiO2纳米纤维复合材料,利用XRD、SEM、FT-IR等检测技术对复合材料的结构进行了表征。研究了光源、Ag掺杂量、不同实验菌种等因素对PANI/Ag-TiO2纳米纤维复合材料抗菌性能的影响。结果表明：在无光照射情况下,PANI/Ag-TiO2纳米纤维复合材料具有良好的抗菌性能,在长波紫外光照射情况下,抗菌性能进一步增强。在浓度1mg/mL时,在无需光照的情况下对4种实验菌种杀菌率均达到99.99%。
一つの材料では所要の機能が発現できない場合、複数の材料を用いて要求される機能を発現させる必要がある。先進超耐熱材料として研究が始められた傾斜機能材料は、材料を構成する組成を連続的または不連続的に変化させることにより、所要の機能を発現する材料である。傾斜機能材料は先進超耐熱材料のみまらず、先進医用材料、光学的材料等あらゆる分野に応用されるため、各種研究がおこなわれている。そこで傾斜機能材料の理論解析の立場から、傾斜機能材料の熱応力について歴史的経緯を踏まえ概説しながら、将来展望を俯瞰する。
