Abstract: A polyurethane foam composition includes a polyol mixture that includes polyether polyol and polymer polyol, an isocyanate compound, a catalyst consisting of a resinizing catalyst and a foaming catalyst, a foaming agent, a chain extender, and a surfactant. The polymer polyol contained in the polyol mixture is present in an amount of 1% to 70% by weight, based on the total weigh of the polyol mixture. The polyether polyol has an average functional group number of 2 to 4 and a mass average molecular weight of 4000 to 8000. The polymer polyol is grafted or dispersed with 20 to 60 wt % of a solid polymer comprising a styrene monomer and acrylonitrile at a weight ratio of 9:1, in polyether polyol having an average functional group number of 2 to 4 and a mass average molecular weight of 3000 to 6000.

Abstract: The present invention relates to a method for the crystallization of protein using nanoparticles as nucleation agents. Precisely, the inventors performed the crystallization of such proteins as Bacillus subtilis YesR, chicken egg white lysozyme, bovine serum albumin, Alicyclobacillus acidocaldarius acetyl-CoA carboxylase, and Listeria monocytogenes hypothetical protein which have his-tag at amino terminal by using gold nanoparticles in diverse sizes and shapes in the presence of Ni2+ ions. As a result, it was confirmed that the chance of successful crystallization was higher with the gold nanoparticles than without the gold nanoparticles and the various crystallization conditions were successfully screened. Therefore, the method for inducing nucleation of the invention can be advantageously used for the disclosure of protein structure by increasing the chance of successful crystallization of protein.
