Publication number: 20140076815Abstract: A treatment process for an aqueous phase which contains oil droplets, possibly of 10-50 nm diameter, in aqueous flow from a hydrocyclone separator, comprises bringing the water into contact with a surface subdivided into areas of differing surface energy and affinity for oil and such that when the surface is submerged in an aqueous phase, oil droplets adhere to it with an apparent contact angle in a range from 90 to 150 degrees. Areas of the surface may reduce their affinity for oil in response to an external stimulus causing controlled release of droplets adhering to the surface. The process may be used to remove oil droplets from water produced by an oil or gas well, after downhole oil water separation or after production at a at a well head, or used to coalesce droplets in such water to a larger size to enable conventional separation.Type: ApplicationFiled: May 14, 2012Publication date: March 20, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Khooi Yeei Tan, Trevor Hughes, Wilhelm Huck, Michaela Nagl

Publication number: 20070202304Abstract: A method for producing a colloid of metallic nanoparticles including the steps of: providing metal ions in solution; providing a stabilizing agent; and reducing said metal ions in the presence of said stabilizing agent, so that metallic nanoparticles are formed with a surrounding layer of said stabilizing agent, wherein the reduction step is carried out at a temperature of not less than 20° C. and not more than 150° C. The metallic nanoparticles are formed of a mixture of transition metal and noble metal, such as Ni—Pd. The resultant nanoparticles have a high stability in terms of size and chemical degradation and so can be stored for long periods. They are therefore particularly suited for forming patterned nanoparticle arrays on a substrate by nanocontact printing for the subsequent formation of a corresponding array of carbon nanotubes or nanofibers via plasma enhanced CVD.Type: ApplicationFiled: February 27, 2006Publication date: August 30, 2007Applicant: Cambridge University Technical Services Limited,Inventors: Vladimir Golovko, Brian Johnson, John Robertson, Mirco Cantoro, Angel Berenguer, Wilhelm Huck, Hongwei Li, Zongqiang Yang

Patent number: 7098145Abstract: A self-assembled monolayer (SAM) is fabricated using either a semi-fluorinated sulphur containing compound, or a sem-fluorinated silane derivative and compressed carbon dioxide (CO2) as the solvent medium. The temperature and/or pressure of the compressed CO2 may be varied during the fabrication process to improve the molecular packing density of the monolayer. By using compressed CO2 as the solvent medium, monolayers with good molecular packing density can be fabricated relatively quickly without the use of environmentally unfriendly solvents.Type: GrantFiled: December 4, 2001Date of Patent: August 29, 2006Assignee: Seiko Epson CorporationInventors: Hitoshi Fukushima, Satoru Miyashita, Masaya Ishida, Andrew Holmes, Wilhelm Huck, Christine K Luscombe
