Abstract: The present disclosure provides nanostructures and nanostructure-based vaccines. Some nanostructures of the present disclosure display antigens capable of eliciting immune responses to infectious agents such as bacteria, viruses, and pathogens. Some vaccines of the present disclosure are useful for preventing or decreasing the severity of infection with an infectious agent, including. for example and without limitation, lyme disease, pertussis, herpes virus, orthomyxovirus, paramyxovirus, pneumovirus, filovirus. flavivirus, reovirus, retrovirus, meningococcus, or malaria. The antigens may be attached to the core of the nanostructure either non-covalently or covalently, including as a fusion protein or by other means disclosed herein. Multimeric antigens may optionally be displayed along a symmetry axis of the nanostructure. Also provided are proteins and nucleic acid molecules encoding such proteins. vaccine compositions, and methods of administration.

Abstract: A method to join a substrate to an object is disclosed using a curable one or two part adhesive composition comprising an effective amount of a stabilized organoborane amine complex initiator and one or more monomers, oligomers, polymers or mixtures thereof having olefinic unsaturation which is capable of polymerization by free radical polymerization.

Abstract: A polymer composition comprises at least an ethylene/?-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/?-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/?-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.
