Abstract: Tunable photonic crystals offer an interesting possibility to adjust the photonic band gap (PBG) as per requirement. Various methods of achieving this have been tried that include polarization of liquid crystals, thermal effects and more. Chromogenic devices provided in accordance with the present invention includ e combinations and subcombinations of electrochromic, photochromic, thermochromic devices featuring TMO based inverse opals having tunable photonic band gaps (PBG) for certain frequencies Electrochromic (EC) materials in which a reversible optical property change can be induced with the application of a small electric field offer a novel possibility to tune the PBG in a controlled and reversible way. The reversible chemical change and the ensuing change of optical constants in these periodically arranged EC materials make the PBG tunability possible In a recent work we have demonstrated for the first time the PBG tunability of EC materials deposited in the form of periodic inverse opals. This earlier work was carried out with the well known Tungsten Trioxide (WO3) EC thin films into which lithium intercalation was done by a dry lithiation method In the present work we report on the fabrication of a simple tunable photonic crystal device based on electrochemical insertion/extraction of lithium based on WO3 inverse opals I n alternative embodiments, any suitable transparent conductor can be utilised instead of Indium Tin Oxide (ITO); any suitable electrochromic transition metal oxide, such as for example Molybdenum Oxide (MoO3), Vanadium Pentoxide (V2O5 ), Titanium Oxide (TiO2), Chromium Oxide (Cr2O3), or Cerium Oxide (CeO2)can be utilised instead of Tungsten Oxide (WO3), and any suitable electrolyte solution can be utilised instead of LiClO4 in Polypropylene Carbonate (LiClO4/PC) solution

IPC: C12N15/87

Abstract: Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.

Abstract: A method and a Mobile Node are provided for authenticating an Advertisement message received from an Access Router through an Access Point. The Advertisement message comprises a Hashed Nonce Value and a Nonce Index corresponding to a Nonce Value held in the Access Router. Upon receiving the Advertisement message from the Access Point, the Mobile Node initiates a process for configuring an IP address, by use of information received in the Advertisement, for having a session with the Access Point and the Access Router. In parallel, either the Access Point or the Mobile Node sends the Nonce Index directly to the Access Router. The Access Router replies with the Nonce Value sent to the Mobile Node. The Mobile Node hashes the Nonce Value received from the Access Router and compares a Result of the hashing with the Hashed Nonce Value. If the Result matches the Hashed Nonce Value, the Advertisement is considered authenticated and the IP address configured according to the Advertisement is kept in the Mobile Node.
