  • Patent number: 9598668
    Abstract: A substrate having a pattern of two or more materials exhibiting different grafting efficiencies for a temperature-responsive polymer that varies its interaction with water in a temperature range of 0 to 80° C. by electron beam irradiation under the same conditions is grafted with the temperature-responsive polymer by simultaneously irradiating the surfaces of the materials with electron beams to obtain a temperature-responsive cell culture substrate. According to this method, a temperature-responsive cell culture substrate having a surface (1) that allows cells to adhere thereto and to grow thereon during cell culturing and that allows the adhering and grown cells to be detached therefrom by changing the culturing temperature and a surface (2) that does not allow the cells to adhere thereto at all can be obtained by a simple process.

  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • Patent number: 8455265
    Abstract: A surface grafted conjugated polyelectrolyte (CPE) is formed by coupling a CPE by a coupling moiety to the surface of a substrate. The substrate can be of any shape and size, and for many uses of the surface grafted CPE, it is advantageous that the substrate is a nanoparticle or microparticle. Surface grafted CPEs are presented that use silica particles as the substrate, where a modified silane coupling agent connects the surface to the CPE by a series of covalent bonds. Two methods of preparing the surface grafted CPEs are presented. One method involves the inclusion of the surface being modified by the coupling agent and condensed with monomers that form the CPE in a grafted state to the substrate. A second method involves the formation of a CPE with terminal groups that are complimentary to functionality that has been placed on the surface of the substrate by reaction with a coupling agent. The surface grafted CPEs are also described for use as biosensors and biocides.

These cells have a heterologous nucleic acid that (i) encodes an isoprene synthase polypeptide and (ii) is operably linked to a promoter. The isoprene produced in such a cultured medium can then be recovered and polymerized into synthetic rubbers and other useful polymeric materials. The synthetic isoprene containing polymers of this invention offer the benefit of being verifiable as to being derived from non-petrochemical based resources. They can also be analytically distinguished from rubbers that come from natural sources. The present invention more specifically discloses a polyisoprene polymer which is comprised of repeat units that are derived from isoprene monomer, wherein the polyisoprene polymer has ?13C value of greater than ?22‰.

  • Patent number: 8084214
    Abstract: The present invention intends to provide a high sensitivity method for identifying the type of a protein contained in each cell with a diameter of ten to several tens ?m and a sample treatment solution required for it. The above is achieved by three steps of (1) treating a slice of a diseased tissue with an aqueous solution containing gold particles and a digestive enzyme, and digesting restrictively a protein of interest, (2) measuring a 2-dimensional distribution of fragmented peptides by TOF-SIMS, and (3) visualizing a 2-dimensional distribution of the target protein in the slice of the diseased tissue using the results of the proteome analysis and by means of a numerical analysis.

  • Patent number: 8076146
    Abstract: A method for evaluating rubber is provided which can evaluate the degree of crosslinking of a crosslinked rubber product within a short period of time without performing any specific treatment. In the above method, the amount of energy shift of the peak (such as the peak of C12p3/2 of chlorinated butyl rubber) of a constituent element of the rubber is measured by photoelectron spectroscopy, and the degree of crosslinking of the rubber is evaluated from the amount of energy shift. In addition, a method for manufacturing a rubber product is also provided which includes the steps of measuring the amount of energy shift of the peak of a constituent element of the rubber product by a photoelectron spectrometer which is installed in a manufacturing line and then feeding back measurement result to adjust heat molding conditions so as to obtain a desired degree of crosslinking.

  • Patent number: 8048679
    Abstract: The present invention provides several methods of determining values of physical or chemical properties of polymers. In these methods, at least two polymer training samples are provided. Characteristics of the polymer microstructures of the training samples are correlated with values of physical or chemical properties of the training samples. These correlations are subsequently applied to the respective characteristics of polymer test samples in order to determine the values of physical or chemical properties of the test samples.

  • Publication number: 20110250696
    Abstract: Provided is a method for high concentration cation exchange metathesis of divalent ions such as calcium with univalent ions such as sodium or potassium. Due to the difference between ionic valences between the exchanged ions, the provided process behavior is strongly dependent upon the selection of resin properties and to total solution normality. A combination of resin properties and solution normality is provided to achieve the cation exchange.
