20160046761 | BIODEGRADABLE SIDE CHAIN LIQUID CRYSTAL ELASTOMERS: SMART RESPONSIVE SCAFFOLDS (SRS) FOR TISSUE REGENERATION - Controlled biodegradable smart responsive scaffold (SRS) materials enhance attachment and viability of cells, i.e. actively guiding their expansion, proliferation and in some cases differentiation, while increasing their biomechanical functionality is an important key issue for tissue regeneration. Chemically build-in functionality in these biodegradable SRS materials is achieved by varying structural functionalization with biocompatible liquid crystal motifs and general polymer composition allowing for regulation and alteration of tensile strength, surface ordering, bioadhesion and biodegradability, bulk liquid crystal phase behavior, porosity, and cell response to external stimuli. Liquid crystal modification of such polymeric scaffolds is an ideal tool to induce macroscopic ordering events through external stimuli. None of these approaches have been demonstrated in prior art, and the use of biocompatible scaffolds that respond to a variety of external stimuli resulting in a macroscopic ordering event is a novel aspect of the present invention. | 02-18-2016 |

20150217131 | TERAHERTZ PULSE RADIATION IN TREATING SKIN DISORDERS - The disclosure provides methods for the treatment of skin disorders through the use of minimally invasive terahertz radiation. The method includes exposing skin cells to terahertz radiation in amount sufficient to modulate gene expression in the skin cells. The modulation of gene expression then results in a reduction of the disease state or aspects thereof in the exposed skin cells. | 08-06-2015 |

20080296526 | Damping valve for a vibration damper - A damping valve for a vibration damper includes a guide sleeve which slides on the piston rod of a vibration damper. An annular damping valve body which is provided with at least one through-opening is fixed axially by positive engagement on the guide sleeve, and the through-opening is covered at least partly by at least one valve disk which is biased by at least one closing spring which is supported at its end at a spring plate connected to the guide sleeve. The damping valve body and a spring plate which is constructed separate from the guide sleeve form a compression chain between two axially spaced stops of the guide sleeve. | 12-04-2008 |

20090027611 | Metal Nanoparticle and Use Thereof for Inducing Chirality in Liquid Crystal Phases - The invention provides a metal nanoparticle comprising a metal and a chiral and/or thiolate group bonded to the metal. The monolayer-protected metal nanoparticle may be used as a chiral dopant in a liquid crystal. Accordingly, the invention also provides a colloidal suspension or dispersion comprising a metal nanoparticle comprising a metal and a chiral and/or thiolate group bonded to the metal, and a liquid crystal. | 01-29-2009 |
20100055042 | Enhancing Clot Busting Medication in Stroke with Directed Drug Convection using Magnetic Nano-Particles - An important step towards successful drug targeting with nanoparticles is developing a method to coat the nanoparticles with a useful drug. BSA was used by us to mimic the actual drug for its cost effectiveness during initial trials. We have successfully immobilized BSA onto three (PEG, PEMA and glutamic acid) out of four different surfactant capped nanocomposites. We found that the BSA immobilized particles showed excellent colloidal stability in water and stayed well suspended without any sign of agglomeration or settling. The suspended particles were easily accumulated using a magnet and could be re-dispersed readily. These properties indicate that the BSA immobilized iron oxide nanocomposites are excellent candidates for directed drug convection (DDC). | 03-04-2010 |
20100195008 | PLANAR NEMATIC LIQUID CRYSTAL CELLS DOPED WITH NANOPARTICLES AND METHODS OF INDUCING A FREEDERICKSZ TRANSITION - Nematic liquid crystal cells with positive dielectric anisotropy that include colloidal suspensions having nanoclusters are provided as well as methods of inducing Freedericksz transitions therein and methods of controlling the alignment of a liquid crystal. | 08-05-2010 |
20100302470 | Planar nematic liquid crystal cells doped with nanoparticles and methods of inducing a freedericksz transition - Nematic liquid crystal cells with positive dielectric anisotropy that include colloidal suspensions having nanoclusters (e.g., CdTe nanoclusters, CdSe nanoclusters) that include a pure monolayer of ligands are provided as well as methods of inducing Freedericksz transitions in the nematic liquid crystal cells and methods of controlling the alignment of a liquid crystal. | 12-02-2010 |
20100303730 | Methods of making iron-containing nanoparticles - A method of making iron-containing nanoparticles (e.g., magnetite nanoparticles) that includes contacting an iron-containing precursor with a reducing agent at a temperature less than 200° C. and allowing the mixture to react to form magnetite nanoparticles. | 12-02-2010 |
20110062385 | BENT-CORE LC DECORATED GOLD NANOCLUSTERS - Novel thiol-terminated bent-core liquid crystals (LCs) are used to decorate gold nanoparticles. Thioacetate or xanthate/xanthogenate functional groups are used to effect the attachment of the LCs to the gold nanoparticles. Such bent-core decorated nanoparticles may be dissolved in bent-core liquid crystal host media to provide polarizable systems which respond quickly to applied electric fields and exhibit other interesting and useful optical and electro-optic behaviour. | 03-17-2011 |
