  • Publication number: 20120313860
    Abstract: An electrical pressure sensor is provided with a method for measuring pressure applied to a sensor surface. The method provides an electrical pressure sensor including a sealed chamber with a top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When the top surface of the sensor is deformed in response to an applied pressure, the elastic polymer medium is compressed. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance between metallic nanoparticles, the electrical resistance is decreased between the first and second electrodes through the elastic polymer medium.

  • Patent number: 8314015
    Abstract: A process of silicon (Si) surface modification is provided for the electrochemical synthesis of Si particles in suspension. The process begins with a Si first substrate with a surface, and forms Si particles attached to the surface. Hydrogen-terminated Si particles are created and the first substrate is immersed in a hexane/1-octene (1/1 volume ratio) solution with a catalytic amount of chloroplatinic acid (H2PtCl6). 1-octene is bonded with the hydrogen-terminated Si particles, creating modified Si particles, with octane capping ligands, attached to the substrate surface. The first substrate is then exposed to ultrasonication, separating the modified Si particles from the first substrate. After removing the first substrate, a suspension is created of modified Si particles suspended in excess hexane/1-octene.

  • Publication number: 20120164212
    Abstract: The invention relates to methods and compositions for selectively directing stem cells to a target tissue within a subject using a system that employs one or more vectors that contain a gene switch/biosensor, a tissue-specific promoter, a gene encoding a stem cell-attracting chemokine, and a gene amplification system. In one embodiment, a stem cell-attracting chemokine is expressed in damaged tissue using a stimulus-responsive vector system. The stimulus can be a physiological stimulus associated with cell injury, such as hypoxia or elevated glucose levels, for example. Expression of the chemokine increases the trafficking of stem cells to the damaged tissue.

  • Publication number: 20120139958
    Abstract: An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.

    Abstract: The present invention provides a novel method to isolate and expand pure progenitor/stem cells from a primary tissue explant, which produces a population enriched in multipotent functional progenitor/stem cells free of contaminating fibroblasts and other cell types. Cardiac progenitor/stem cells isolated by this method maintain their self-renewal and clonogenic character in vitro and differentiate into normal cells in myocardium, including cardiomyocytes, endothelial cells, and smooth muscle cells, after transplantation into ischemic hearts. The present invention also includes substantially pure populations of multipotent progenitor/stem cells, e.g., cardiac progenitor/stem cells, and their use to treat and prevent diseases and injuries, including those resulting from myocardial infarction.

    Abstract: Disclosed are cleaning solutions. More particularly, non-toxic solutions of base, water, alcohol and detergent, that effectively and surprisingly eliminate contaminating aliphatic acids in aqueous solutions. When present as a foam or even a contaminating film remaining on various parts and surfaces, aliphatic acid contaminants can be present a large and costly problem in manufacturing operations, cleaning tasks, personal hygiene. The need to remove such contaminants arises in a myriad environments and situations, such as during the manufacture of detergents, pharmaceuticals, consumer products, coring and core analysis, manipulation of oils, fuels, fermentation applications, manufacture of emollients, moisturizers, liquors, foods such as seafood, milk, butter and other dairy products, water processing, paper products, tissue culture, reusable clinical equipment, and the like.
