摘要:In exemplary implementations of this invention, hydrothermal synthesis of zinc oxide nanowires is morphologically controlled. Metal complex ions are used to suppress growth in a face-selective manner, by electrostatic crystal growth inhibition. This permits the aspect ratio (height/diameter) of the nanowires to be dynamically tuned over a wide range, from needle-like nanowires that are efficient field emitters to flattened nanowires with a platelet-like shape. The nanowire synthesis is all inorganic and occurs at low temperatures (e.g., <=60° C.). The growth inhibition may be predictively modeled, using speciation plots and treating non-zinc complex ions as ligands. Microfluidic channels may be used for the synthesis, with different solutions flowing down different channels, permitting nanowires with different properties to be synthesized in parallel. This invention may be used to produce field emission devices and nanowire-embedded AC electroluminescent devices, and for in-situ fabrication of spatially complex integrated devices in a polymeric microfluidic system.

摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

权利人:INOLEX INVESTMENT CORP
摘要:A process is incorporated herein for the synthesis of bio-1,2-alkanediols, comprising: providing a bio-alkene having a carbon chain of about 5 to about 20 carbon atoms and a bio-1-alkene regioselectivity of at least about 80%, at least about 92% and/or at least about 95%; and converting the bio-alkene to a bio-1,2-alkanediol having a carbon chain length of about 5 to about 20 carbon atoms. Methods for treating catalysts which may be incorporated in the process for the synthesis of bio-1,2-alkanediols are also included herein. Such bio-1,2-alkanediols are used in compositions and products alone as antimicrobial materials, or with existing bio-compounds and/or antimicrobials, preservatives, alternative preservation systems and/or hurdle technology components. The bio-1,2-alkanediols incorporate a natural and bio-based pathway for antimicrobial effects in various compositions such as cosmetic, pharmaceutical, industrial and household products.

摘要:A new type of hydrazide compounds is disclosed corresponding to general formula (A): (A) the symbols of which are explained in the description. Examples of synthesis are given. Incorporation of these diacyl hydrazides into the silver halide emulsion layer(s) of a photographic material causes a significant increase in sensitivity.
