    • Methods for using modified single wall carbon nanotubes (“SWCNTs”) to detect presence and/or concentration of a gas component, such as a halogen (e.g., Cl2), hydrogen halides (e.g., HCl), a hydrocarbon (e.g., CnH2n+2), an alcohol, an aldehyde or a ketone, to which an unmodified SWCNT is substantially non-reactive. In a first embodiment, a connected network of SWCNTs is coated with a selected polymer, such as chlorosulfonated polyethylene, hydroxypropyl cellulose, polystyrene and/or polyvinylalcohol, and change in an electrical parameter or response value (e.g., conductance, current, voltage difference or resistance) of the coated versus uncoated SWCNT networks is analyzed. In a second embodiment, the network is doped with a transition element, such as Pd, Pt, Rh, Ir, Ru, Os and/or Au, and change in an electrical parameter value is again analyzed. The parameter change value depends monotonically, not necessarily linearly, upon concentration of the gas component. Two general algorithms are presented for estimating concentration value(s), or upper or lower concentration bounds on such values, from measured differences of response values.

    • The present invention provides a series of cyclin-dependent protein kinases (Cdks) inhibitors, Scutellaria flavonoid organic amine derivatives, synthesis and use thereof. The preparation method is as follows: taking Baicalein (or Wogonin) from Scutellaria baicalensis as lead compound, mixting it with formaldehyde solution and organic amine compounds based on the molar ratio of 1:1-1.2:1-1.2, adding methanol of duplicate weight than baicalein and reacting at 50-70° C., filtering the sediment and washing and then drying so as to get the product with a content of not less than 97% (weight). Similar to Flavopiridol and P276-00, the activity of baicalein organic amine derivatives inhibiting Cdks has an increase of 50 times compared with that of Baicalin. It can selectively induce apoptosis of the proliferative phase cancer cells, which has scarcely any influence to the normal structure, and it belongs to anticancer drugs of cell cycle inhibitor kind. The product has a rich source of raw materials and has simple process, high purity, low cost, clear metabolic mechanism, high efficiency and low toxicity, which can be made into oral preparations or injections together with acid salts and is expected to become high efficient and low toxicity anti-cancer and AIDS drugs.

    • Hybrid crystalline organic-inorganic quantum confined systems are disclosed, which contain alternating layers of a bifunctional organic ligand and a II-VI semiconducting chalcogenide, wherein the semiconducting chalcogenide layers contain chalcogenides have the formula MQ, in which M is independently selected from II-VI semiconductor cationic species and Q is independently selected from S, Se and Te; and the bifunctional organic ligands of each organic ligand layer are bonded by a first functional group to an element M of an adjacent II-VI semiconducting chalcogenide layer and by a second functional group to an element M from the adjacent opposing II-VI semiconducting chalcogenide layer, so that the adjacent opposing II-VI semiconducting chalcogenide layers are linked by the bifunctional organic ligands of the organic ligand layers. Optical absorption experiments show that these systems produce a significant blue shift in their optical absorption edges, 1.2-1.5 eV, compared to a shift of 1.0 electron volt by the best grown II-VI or II-V semiconducting quantum colloidal dots. In addition, the II-VI confined layers in these systems possess a perfectly periodic arrangement.
