We made transparent arteriole membranous models by using grayscale lithography. We employed a sacrificial model made of WAX and PVA mixture as a novel molding material. Our goal is to complement previous surgical simulators for practice and rehearsal of medical treatments. Since block vessel models cannot recreate moderate compliance which is similar to that of the real blood vessel, here we propose...
In this study, we succeeded in fine construction of the PLCL (poly-L-lactide-cocaprolactone) scaffold with micrometer range resolution using photolithography. PLCL is a biodegradable polymer which is used as a material of the scaffold to reproduce the blood vessel. Photolithography known as a technique of microfabrication was used for the processing of PLCL. By this technique, we fabricated a sheet-like...
The soft magnetic properties of amorphous Fe-Si-B-Cu-Nb alloys are markedly improved by annealing the alloys above the crystallization temperature. The magnetic permeability of the annealed Fe74SixB22-xCu1Nb3 alloys shows a maximum value at an Si concentration of x=14. The precipitation of μ-Fe grains is observed for the annealing temperature giving the highest magnetic permeability. The lattice constant...
