标 题 :Synthesis of cupronickel nanowires and their application in transparent conducting films
发明人：WILEY BENJAMIN
权利人:UNIV DUKE
摘要:A method of synthesis to produce a conductive film including cupronickel nanowires. Cupronickel nanowires can be synthesized from solution, homogeneously dispersed and printed to make conductive films (preferably < 1,000 Ω/sq) that preferably transmit greater than 60% of visible light.

摘要:Magnetic paper-forming fibers have a particulate magnetic material incorporated within the fibers, as distinct from between the fibers; this can be achieved by loading the lumens of cellulosic fibers with magnetic particles or by generating magnetic particles in situ in a paper-forming fiber which contains ionic groups effective for ion exchange with ferrous ions; the fibers can be employed to produce single layer or multi-layererd magnetic papers for information storage, security paper applications, paper handling, reprographic applications such as magnetographic printing substrate as well as for speciality uses such as electromagnetic shielding, magnetic separation of antibodies based on selective adsorption.

标 题 :Nucleotide analog composition and synthesis method
发明人：MUNGER JR JOHN D; ROHLOFF JOHN C; SCHULTZE LISA M
权利人:GILEAD SCIENCES INC
摘要:The invention provides a composition comprising bis(POC)PMPA and fumaric acid (1:1). The composition is useful as an intermediate for the preparation of antiviral compounds, or is useful for administration to patients for antiviral therapy or prophylaxis. The composition is particularly useful when administered orally. The invention also provides methods to make PMPA and intermediates in PMPA synthesis. Embodiments include lithium t-butoxide, 9-(2-hydroxypropyl) adenine and diethyl p-toluenesulfonylmethoxyphosphonate in an organic solvent such as DMF. The reaction results in diethyl PMPA preparations containing an improved by-product profile compared to diethyl PMPA made by prior methods.
