• Trialkylsulfonium dicyanamides - a new family of ionic liquids with very low viscosities

  日期：——

  Trialkylsulfonium dicyanamides show surprisingly low viscosities down to −20 °C and are therefore highly interesting liquid materials for separation processes and electrolyte applications at low temperatures.

  三烷基磺铵二氰胺在低至 -20 °C 时表现出令人惊讶的低粘度，因此在低温下作为分离过程和电解质应用的液体材料非常有趣。

  A new series of low-melting, low-viscosity, hydrophobic ionic liquids based on relatively small tertiary sulfonium cations ([R1R2R3S]+, wherein R1, R2, R3 = CH3 or C2H5, R3 = CH2CH2OCH3, CH2CH2COOCH3, CH2CH2CN) and bis(fluorosulfonyl)imide (FSI−) anion have been prepared and characterized. The important physicochemical and electrochemical properties of these salts, such as melting point, glass transition

• Molten and Solid Trialkylsulfonium Iodides and Their Polyiodides as Electrolytes in Dye-Sensitized Nanocrystalline Solar Cells

  DOI：10.1021/jp036859v

  日期：2003.12.1

  Potential new electrolytes for dye-sensitized nanocrystalline solar cells (DNSCs) of Gratzel type based on trialkylsulfonium iodides have been investigated. Room temperature molten salts of (Et2MeS)I, (Bu2MeS)I, and (Bu2EtS)I, with iodine in low concentrations, revealed good conducting abilities. DNSCs using iodine-doped (Bu2MeS)l as electrolyte achieved an overall light-to-electricity conversion efficiency of 3.7% in simulated AM 1.5 solar light at a light intensity of 0.1 Sun. The effects from varying the temperature during the IN measurements were studied, as well as the effects of 4-tert-butylpyridine treatment of the electrodes.
• Laparoscopic Telescope with Alpha Port and Aesop to View Open Surgical Procedures

  Laparoscopy has advanced surgery by allowing the surgeon to operate within a patient's abdominal and pelvic cavity with minimal trauma and scarring. The coupling of a video camera to the laparoscopic telescope has had the secondary effect of allowing others to view the surgical field either on color video monitors or by watching the video feed over the Internet at a remote location. These advancements have allowed better teaching and mentoring of operations. Open procedures can benefit from this technology as well but have suffered in the past from inadequate methods to depict the open surgical field. We used the Alpha Port and Aesop robot to position a sterile laparoscopic telescope near the surgical field to view open cholecystectomies performed on five pigs and to send the video feed over the Internet to remote physicians. Viewing the video on the monitor, the surgeons performed the operation in a comfortable ergonomic upright position. Both the surgeons and the remote physicians found the quality of the video to be excellent, and the remote physicians felt comfortable learning and mentoring surgical procedures using this technique.
