Abstract: Methods and apparatus for long read, label-free, optical nanopore long chain molecule sequencing. In general, the present disclosure describes a novel sequencing technology based on the integration of nanochannels to deliver single long-chain molecules with widely spaced (>wavelength), ˜1-nm aperture “tortuous” nanopores that slow translocation sufficiently to provide massively parallel, single base resolution using optical techniques. A novel, directed self-assembly nanofabrication scheme using simple colloidal nanoparticles is used to form the nanopore arrays atop nanochannels that unfold the long chain molecules. At the surface of the nanoparticle array, strongly localized electromagnetic fields in engineered plasmonic/polaritonic structures allow for single base resolution using optical techniques.

Abstract: A polymer composition including polymer particles containing a first polymer and a second polymer is disclosed. The first polymer has a crosslinked core and has a glass transition temperature in the range of ?30° C. to 100° C. The second polymer containing select crosslinking groups and has a glass transition temperature in the range of ?10° C. to less than 18° C. A process to prepare the polymer composition is provided. Also provided are a coated article containing a coating prepared from the polymer composition and a method of preparing the coated article. The polymer composition has good low temperature film formation and provides a film with an acceptable level of hardness.

Abstract: An aqueous polymer blend composition including a predominant amount of soft polymer particles and a minor amount of hard polymer particles is provided. The soft polymer particles contain, as copolymerized units, 70 to 99.7% by weight monoethylenically unsaturated (meth)acrylic monomer and from 0.3 to 10% by weight monoethylenically unsaturated acid monomer, based on weight of soft polymer particles. The soft polymer particles are made by a select process including redox polymerization or polymerization in the presence of excess unreacted monomer. The aqueous polymer blend composition is useful for preparing dry coatings having improved dirt pickup resistance and acceptable scrub resistance. A method is provided for preparing a dry coating from the aqueous polymer blend composition.

Abstract: The present invention is directed to traffic paint compositions, which dry faster than conventional waterborne traffic paints and to a method of producing traffic paint road markings made therefrom. The traffic paint composition of the present invention includes a blend of an anionically stabilized polymer binder, a polyfunctional amine polymer having an amine and an acid functionality therein and an amount of volatile base sufficient to raise the pH of the composition to a point where essentially all of the polyfunctional amine polymer is in a non-ionic state. The traffic paint composition of the present invention further provides improved storage stability.

Abstract: The present invention is directed to a method of producing wear resistant traffic paint composition. In accordance with the method, a traffic marking of a traffic paint composition having low GPC number average molecular weight latex binder when applied to the road surface exhibits improved wear resistance over those traffic paint compositions having high GPC number average molecular weight latex binders. The wear resistance is further enhanced by modifying the latex polymer used in the composition with acetoacetyl functional pendant moiety and amino silane.
