Control of cell adhesion by nanoporous gold
HAKAMADA Masataka
We investigated the activity of cells on nanoporous gold (NPG) with nanometer-sized pores and ligaments. HeLa cells were inactivated by NPG substrates after initial temporary adsorption because of the conformational deterioration of fibronectin, which is an important protein for the adsorption of HeLa cells. On the other hand, human mesenchymal stem cells (hMSCs) were not adsorbed on NPG substrates, which may be due to local conformational change in collagen, which mediates the adsorption of hMSCs. Furthermore, cyclic stretching by the actuation of NPG significantly enhanced the proliferation of human embryo-derived fibroblasts., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2019/04 -2022/03, Grant-in-Aid for Scientific Research (B), Kyoto University
Grain boundary enhanced ductility of ultrafine grained materials
Miyamoto Hiroyuki
Severe plastic deformation (SPD) can fabricate high-strength materials by forming ultrafine grained (UFG) microstructure. But, in general, as in other methods, strengthening accompanies ductility loss. Low ductility, which is usually evaluated by the uniaxial tensile tests, has been attributed to low strain hardening of UFG structure where dislocation slip and its accumulation is very limited. In the present work, it is shown that the compressive ductility, or classically called malleability of UFG materials can be comparable or potentially superior to that of coarse-grained counterparts in an appropriate stress state. The high malleability of UFG materials by SPD can be attributed to the unique deformation mechanism related with non-equilibrium grain boundaries and their high damage tolerance. The present results present a prospect for expanding industrial application of UFG materials, which has been limited because of low tensile ductility., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2018/04 -2021/03, Grant-in-Aid for Scientific Research (C), Doshisha University
