| 1 | Radical Addition of Perfluorinated Alkyl Iodides to Multi- Layered Graphene and Single-Walled Carbon Nanotubes显示文摘A simple one-pot reaction that serves to functionalize graphite nanosheets(graphene)and single-walled carbon nanotubes(SWNTs)with perfluorinated alkyl groups is reported.Free radical addition of 1-iodo-1H,1H,2H,2H-perfluorododecane to ortho-dichlorobenzene suspensions of the carbon nanomaterial is initiated by thermal decomposition of benzoyl peroxide.Similarly,UV photolysis of 1-iodo-perfluorodecane serves to functionalize the carbon materials.Perfluorododecyl-SWNTs,perfluorododecyl-graphene,and perfluorodecyl-graphene are characterized by infrared(IR)and Raman spectroscopy,X-ray photoelectron spectroscopy(XPS),thermogravimetric analysis(TGA),and atomic force microscopy(AFM).The products show enhanced dispersability in CHCl3 as compared to unfunctionalized starting materials.The advantage of this one-pot functionalization procedure lies in the use of pristine graphite as starting material thereby avoiding the use of harsh oxidizing conditions. | Christopher E.Hamilton Jay R.Lomeda Zhengzong Sun James M.Tour Andrew R.Barron | 2010 | Nano Research2010，3，2： | 5 |
| 2 | First demonstration of an all-solid-state optical cryocooler显示文摘Solid-state optical refrigeration uses anti-Stokes fluorescence to cool macroscopic objects to cryogenic temperatures without vibrations.Crystals such as Yb3+-doped YLiF4(YLF:Yb)have previously been laser-cooled to 91 K.In this study,we show for the first time laser cooling of a payload connected to a cooling crystal.A YLF:Yb crystal was placed inside a Herriott cell and pumped with a 1020-nm laser(47 W)to cool a HgCdTe sensor that is part of a working Fourier Transform Infrared(FTIR)spectrometer to 135 K.This first demonstration of an all-solid-state optical cryocooler was enabled by careful control of the various desired and undesired heat flows.Fluorescence heating of the payload was minimized by using a single-kink YLF thermal link between the YLF:Yb cooling crystal and the copper coldfinger that held the HgCdTe sensor.The adhesive-free bond between YLF and YLF:Yb showed excellent thermal reliability.This laser-cooled assembly was then supported by silica aerogel cylinders inside a vacuum clamshell to minimize undesired conductive and radiative heat loads from the warm surroundings.Our structure can serve as a baseline for future optical cryocooler devices. | Markus P.Hehlen Junwei Meng Alexander R.Albrecht Eric R.Lee Aram Gragossian Steven P.Love Christopher E.Hamilton Richard I.Epstein Mansoor Sheik-Bahae | 2018 | Light(Science & Applications)2018，7，1： | 1 |
