Effect of γ-Ray Irradiation on Mechanical Properties of PVA and Acetalized PVA Films
Kobunshi Kagaku, 1961 およびアセタール化PVA皮膜の強伸度に及ぼすγ 線の照射効果について研究した。照射は室温で真空中および空気中で行なった。熱処理した皮膜は真空中空気中いずれで照射しても, よく似た挙動を示し140℃ で熱処理した皮膜の強度は4×107r程度の照射により15%程度増加し, 200℃ で熱処理した皮膜では照射によりほとんど変らなかった。伸度は両皮膜共照射量の増加とともに減少した。アセタール化皮膜の強伸度は真空中空気中いずれで照射してもかなり低下し特に空気中照射の場合の低下は著しい。

Control of nanostructures in PVA, PVA/chitosan blends and PCL through electrospinning
Bulletin of Materials Science, 2008 Aqueous solutions of polyvinyl alcohol (PVA) were electrospun and its characteristics were studied as a function of applied potential, tip-target distance and solution flow rate. Solutions of PVA and chitosan were homogeneously mixed and electrospun to result in blend nanofibres and their properties were investigated.

Microneedles Mediated Delivery of Nanodiamonds for Quantum Sensing of Free Radicals in Skin Tissue
Advanced Materials Technologies, EarlyView.Fluorescent nanodiamonds are nanoscale sensors capable of monitoring cellular stress responses. However, to function effectively, they must be delivered into cells or tissues. Here, we demonstrate their application in the skin by developing a dissolvable microneedle platform that dissolves after skin insertion, enabling the delivery of nanodiamonds ...
