    Abstract: Coating compositions that include acrylic polymers as reinforcing agents. The coating compositions are radiation-curable and include a multifunctional acrylate component, an acrylic monomer diluent, an acrylic polymer, and a photoinitiator. The acrylic polymer is not radiation-curable and lacks hydrogen-donor groups, urea groups, and urethane groups. The acrylic polymer is non-reactive and does not chemically bond to the crosslinked network formed by curing the acrylate components. Instead, the acrylic polymer reinforces the cured network through physical interactions. Representative acrylic polymers include (meth)acrylates that lack substituents with hydrogen-donor, urea, and urethane groups.

In order to guarantee an effective, directed reinforcement effect within an inflatable sail without limiting the lifespan of said sail, the unitary body has, in the cross-section thereof, an oblong outline, wherein the ratio of the maximum width (e) of said outline, which corresponds to a thickness of the unitary body, to the maximum length (l) of said outline, which corresponds to a width of the unitary body, is less than 0.06, a plurality of filaments (821) being arranged in series over the thickness of the unitary body.

  • Patent number: 8652347
    Abstract: Provided are new compositions of ruthenates in the pervoskite and layered pervoskite family, wherein the ruthenate compositions exhibit large magnetoresistance (MR) and electric-pulse-induced resistance (EPIR) switching effects, the latter observable at room temperature. This is the first time large MR and EPIR effects have been shown together in ruthenate compositions. Further provided are methods for synthesizing the class of ruthenates that exhibits such properties, as well as methods of use therefor in electromagnetic devices, thin films, sensors, semiconductors, insulators and the like.
