Enzymatic synthesis and antioxidant properties of poly(rutin).
Rutin, quercetin-3-rutinoside, is one of the most famous glycosides of flavonoid and widely present in many plants. In this study, we performed an oxidative polymerization of rutin using… Expand
Inhibition effects of (+)-catechin-aldehyde polycondensates on proteinases causing proteolytic degradation of extracellular matrix.
Inhibition effects of (+)-catechin-aldehyde polycondensates against the activity of proteinases, Clostridium histolyticum collagenase (ChC) and human neutrophil elastase (HNE) causing proteolytic… Expand
The development of polymer-clay nanocomposite materials, in which nanometer-thick layers ofclay are dispersed in polymers, was first achieved about 15 years ago. Since then, the materialshave… Expand

Ring rolling process simulation by the three dimensional finite element method
Abstract The finite element code “RING” was developed for the analysis of ring rolling. A special feature of the program is the updating procedure in three-dimensional deformation. A spatially fixed… Expand
Oxidative polymerization of phenols revisited
Abstract This paper presents an overview on recent developments of oxidative polymerizations of phenols, particularly focusing on the coupling selectivity. In 1959, Hay et al. discovered an oxidative… Expand
Laccase‐catalyzed Synthesis and Antioxidant Property of Poly(catechin)
Catechin was oxidatively polymerized by laccase in a mixture of a polar organic solvent and buffer to give a new class of flavonoid polymers. Myceliophthora laccase showed high catalytic activity for… Expand
Laccase‐Catalyzed Oxidative Polymerization of Phenols
Laccase-catalyzed oxidative polymerization of phenol and its derivatives has been performed in aqueous organic solvents at room temperature in air. Laccase derived from Pyconoporus coccineus… Expand
