Patent number: 7217746Abstract: Coating materials comprising polymeric particles in a geometrically ordered array are disclosed. The particles can be formed from materials having different glass transition temperatures; this allows for phase segregation between areas of different glass transition temperatures within each particle. Typically, at least 50 percent of the particles will form a hexagonal array, capable of exhibiting Bragg diffraction. Because the particles within the array do not coalesce to any appreciable extent, significant surface area is provided by the present coating materials. Thus, the present materials have particularly good sound deadening properties. Substrates coated with the present materials are also disclosed, as are methods for inhibiting sound transmission through a substrate using these coatings.Type: GrantFiled: May 18, 2001Date of Patent: May 15, 2007Assignee: PPG Industries Ohio, Inc.Inventors: Calum H.

Patent number: 7217785Abstract: The term “homology” or “homologous” means an amino acid similarity measured by the program, BLAST (Altschul et al (1997), “Gapped BLAST and PSI-BLAST: a new generation of protein database search programs”, Nucleic Acids Res. 25:33 89–3402), and expressed as —(% identity n/n). In measuring homology between a peptide and a protein of greater size, homology is measured only in the corresponding region; that is, the protein is regarded as only having the same general length as the peptide, allowing for gaps and insertions.Type: GrantFiled: May 8, 2002Date of Patent: May 15, 2007Assignee: The Regents of The University of CaliforniaInventor: John K. Bielicki
