Summary In observations of the long-term properties of a series of Cr(III)/polyacrylamide (PAAM) gels, the gels either underwent syneresis upon aging or swelled in contact with excess brine. Both syneresis and swelling can substantially change the vo

A series of water-soluble starch-polyacrylamide graft copolymers (ST-g-PAM) were prepared by Ce4+-initiated graft copolym-erizations of acrylamide (AM) onto starch (ST) dissolved in water at 30°C. The copolymers were found to contain 3-33% (wt) of S

A mutant aspartate transcarbamoylase, ATCase231, has been crystallized at neutral pH. The mutant enzyme has a single substitution of aspartic acid in place of glycine within the catalytic chain and shows not only the loss of enzyme activity but also
