Nanohybrid PVA/ZrO2 and PVA/Al2O3 electrospun mats
Chemical Engineering Journal, 2008Abstract Fibrous poly(vinyl alcohol)/zirconia and poly(vinyl alcohol)/alumina nanohybrids were obtained by electrospinning technique, the applied voltage ranging between 12 and 16 kV. The actual nanofiller content ranged between 2 and 9 wt%. Electrospun nanohybrids consisted of uniform fibers free of defects. The average fiber diameter was around 600

Cell response to Electrospun PVA and PVA/Chitosan nanofibers
2009 IEEE 35th Annual Northeast Bioengineering Conference, 2009PVA and chitosan have been used for many tissue engineering applications. However, most of the studies use only single polymer to fabricate nanofibers. Therefore, the purpose of this study is to fabricate PVA and PVA/Chitosan nanofiber scaffold for potential tissue engineering applications. The nanofrous scaffold was produced via electrospinning.

Dependence of structure of dehydrated PVA on the crystallinity of the original PVA
Journal of Polymer Science: Polymer Chemistry Edition, 1975AbstractPoly(vinyl alcohol) (PVA) films having different crystallinities were prepared by elongating PVA films to different degrees and heating the films with and without elongation treatment at several temperatures between 60 and 200°C. Then, they were dehydrated by heating from 80°C to 230 or 330°C in hydrogen chloride gas.

Proceedings of the seventh ACM SIGKDD international conference on Knowledge discovery and data mining, 2001
In this paper, we present PVA, an adaptive personal view information agent system to track, learn and manage, user's interests in Internet documents. When user's interests change, PVA, in not only the contents, but also in the structure of user profile, is modified to adapt to the changes. Experimental results show that modulating the structure of user

Biodegradation of PVA‐based formulations
Macromolecular Symposia, 1999AbstractInvestigation of the biodegradability of water soluble poly(vinyl alcohol) (PVA) based blown films was carried out under different lab‐scale environmental conditions. In particular respirometric tests were utilized in order to evaluate the biodegradability of PVA films in composting, in modified Sturm test and in soil burial simulation tests ...
