Patent number: 7883648Abstract: Lipobeads (liposome-encapsulated hydrogels) combine properties of hydrogels and liposomes to create systems that are sensitive to environmental conditions and respond to changes in those conditions in a fast time scale. Lipobeads may be produced by polymerizing anchored or unanchored hydrogels within liposomes or by mixing anchored or unanchored hydrogels with liposomes. Giant lipobeads may be produced by shrinking unanchored nanogels in lipobeads and fusing the resulting lipobead aggregates, long-term aging of anchored or unanchored lipobeads, or mixing anchored or unanchored aggregated nanogels with liposomes. Poly(acrylamide), poly(N-isopropylacrylamide), and poly(N-isopropylacrylamide-co-1-vinylimidazole) lipobeads were produced and characterized.Type: GrantFiled: November 16, 2009Date of Patent: February 8, 2011Assignee: Polytechnic Institute of New York UniversityInventors: Sergey Kazakov, Marian Kaholek, Kalle Levon

Patent number: 7865055Abstract: The invention relates to coated optical fibers comprising soft primary coatings and to such primary coatings for protecting glass optical fibers having a sufficient high resistance against cavitation. In particular, the primary coatings have a cavitation strength at which a tenth cavitation appears (?10cav) of at least about 1.0 MPa as measured at a deformation rate of 0.20% min?1 and of at least about 1.4 times their storage modulus at 23° C. The coating preferably shows strain hardening in a relative Mooney plot, preferably has a strain energy release rate Go of about 20 J/m2 or more, and preferably has a low volumetric thermal expansion coefficient. The invention furthermore provides a method and apparatus for measuring the cavitation strength of a primary coating.Type: GrantFiled: November 13, 2009Date of Patent: January 4, 2011Assignee: DSM IP Assets B.V.Inventors: Markus J.
