Patent number: 8529784Abstract: Methods and apparatuses for generating electrically-conductive and/or semi-conductive films, and more specifically, methods and apparatuses for generating conductive and/or semi-conductive films having nanoscale features are provided. In one embodiment, an electrically-conductive or semi-conductive film (e.g., a gold layer of less than 50 nanometer thickness) is provided on a substrate (e.g., a poly(dimethylsiloxane) (PDMS) stamp). The substrate may optionally include patterns or features having raised and recessed portions. A first portion of the film may be removed from the substrate, e.g., by methods such as physically contacting the first portion of the film with a surface to which the first portion preferentially adheres. This process can leave a second portion of the film remaining on the substrate. In some embodiments, the second portion includes at least one region having a dimension substantially parallel to a portion of the substrate i.e., of less than 50 nanometers.Type: GrantFiled: August 9, 2006Date of Patent: September 10, 2013Assignee: President and Fellows of Harvard CollegeInventors: Tingbing Cao, Qiaobing Xu, Adam Winkleman, George M.

Patent number: 8431036Abstract: In a first aspect a fire fighting foaming composition contains a partially acetylated polyvinyl alcohol. In a second aspect the fire fighting foaming composition contains chitosan together with a surfactant such as a protein derived surfactant or a hydrocarbon surfactant which is either amphoteric or non-ionic. The compositions can form effective fire fighting foams in the absence of fluorinated surfactants and other fluorinated compounds.Type: GrantFiled: June 29, 2007Date of Patent: April 30, 2013Assignee: Kidde IP Holdings LimitedInventors: David John Mulligan, Nigel Frank Joslin
