Viscoelastic Relaxation and Molecular Mobility of Hyperbranched Poly(epsilon-caprolactone)s in Their Melt State

Song H.J., Choi J., Kwak S-Y, Seoul National University, KR

The dynamic viscoelastic relaxation behavior and the molecular mobility of hyperbranched poly(epsilon-caprolactone)s (HPCLs) possessing the molecular architectural variation and their linear counterpart, linear poly(epsilon-caprolactone) (LPCL), were characterized and evaluated in conjunction with their specific molecular [...]

On the Development of a Nanocrystalline Yttria Stabilised Zirconia Ceramic Capable of Superplastic Deformation at Relatively Low Temperatures

Bhattacharya S.S., Betz U., Hahn H., IIT Madras, IN

Superplastic deformation behaviour is now well established in fine-grained zirconia ceramics at fairly high temperatures (well above 0.5Tm, where Tm is the absolute melting point). In this study, an attempt was made to develop a [...]
