We investigated the effects of bioactive-peptides from hydrolysates of flounder fish muscle (FFM) on antioxidant activity. The hydrolysates were prepared by enzymatic reactions of FFM using eight commercial proteases such as papain, pepsin, trypsin, neutrase, alcalase, kojizyme, protamex, and α-chymotrypsin.

A Micro Review of Reversible Addition/Fragmentation Chain Transfer (RAFT) Polymerization

We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands

We presents an article about Copper(I)-mediated Living Radical Polymerization in the Presence of Pyridylmethanimine Ligands, and the emergence of living radical polymerization mediated by transition metal catalysts in 1995, which was a seminal piece of work in the field of synthetic polymer chemistry.

Protokoły

Przygotowanie monodyspersyjnych kulek polimerowych

Sfery polimerowe służą jako szablony kryształów. Metody syntezy dają duże ilości.

Preparation of Monodisperse Polymer Spheres

Monodisperse, surfactant-free polymer spheres for use as colloidal crystal templates can be easily obtained in reasonably large quantities. Typical synthesis methods for poly(methyl methacrylate) (PMMA) and poly(styrene) (PS) by emulsifier free emulsion polymerization are described below and yield spheres several hundred nanometers in diameter.

Typical Procedures for Polymerizing via RAFT

We presents an article featuring procedures that describe polymerization of methyl methacrylate and vinyl acetate homopolymers and a block copolymer as performed by researchers at CSIRO.

Concepts and Tools for RAFT Polymerization

Sigma-Aldrich presents an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.
