In situ self cross-linking of polyvinyl alcohol battery separators [PDF]

open access: yes, 1979
A battery separator was produced from a polyvinyl alcohol sheet structure which was subjected to an in situ, self crosslinking process by selective oxidation of the 1,2 diol units present in the polyvinyl alcohol sheet structure.

POLYVINYL ALCOHOL AS AN EMBEDDING MEDIUM FOR LIPID AND ENZYME HISTOCHEMISTRY

open access: yes, 1962
Polyvinyl alcohol is a highly polar, water-soluble resin. Fixed, washed specimens are soaked in a mixture of 15% polyvinyl alcohol, 15% glycerol and 70% water, which is then allowed to dry at room temperature to a hard, sectionable block. Sections 1-100

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

open access: yesAdvanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.
