    Experimental section是sci文章写作中最简单的一个部分,不过也挺有意思的,它有意无意之间可能会反映作者的心态与素养.今天先从简单的开始吧,给大家总结下Experimental Section里面仪器表征部分的一些写法,大家应该用得上,不过不意见大家直接用哈,最好稍微有点变动.

基本介绍

    Experimental section里面的仪器表征部分(Characterizations)主要是跟读者交代 本文所采用的是哪种仪器,使用的什么条件,有什么值得注意的问题等等. 不过,每个人严谨的程度不一样,文中所给出的信息的全面程度也会不一样.在这里,还是意见大家尽可能写得细致一点,.今天给大家分享一些General的写法.

在写论文中,论文润色可以节省很多发文时间,在此推荐editsprings提供的sci论文翻译润色服务。

以下内容蓝色部分可以作为模板

1. XRD:

理论上应该给出以下信息: 仪器型号,工作电压和电流,靶材,步长 等.

A. Grazing incidence X-ray diffraction (GIXRD) patterns were recorded on a Phillips X'Pert Panalytical diffractometer operating at  40 mA and 45 kV using monochromated Cu Kα1 radiation (incident angle = °, λ = Å, step size = °, integration time 20 s/step).(Ref.: J. Am. Chem. Soc . 2012 , 134, 17253−17261 )

 

B.  Wide-angle XRD patterns were recorded on a Rigaku Ultimate IV diffractometer using Cu Kα radiation ( 40 kV, 40 mA, 10° min−1 from 10 to 80° ). (Ref.: J. Phys. Chem. C  2017 , 121, 4343−4351)

 

当然,您真要写得简略点,审稿人也不太会计较

C. Powder X-ray diffraction (XRD) measurements were recorded on a Rigaku D/MAX-RB diffractometer with monochromatized Cu Kα radiation (λ = 0.15418 nm).

 

2. XPS

理论上应该给出: 仪器型号,X射线源,荷电校正的标准 等等

A. X-ray photoelectron spectroscopy (XPS) studies were carried out on an ESCALAB 250 (ThermoScientific) using an Al Kα  monochromated ( 150 W, 20 eV pass energy, 500 μm spot size ) or a Mg Kα nonmonochromated flood (400 W, 75 eV pass energy)  source. The samples were charge-neutralized using an in-lens electron source combined with a low-energy Ar+ flood source. Spectra were analyzed using ThermoScientific Avantage 4.75 software . The Au 4f7/2 signal at 84.0 eV was used to calibrate the binding energy scale. (Ref.:  J. Am. Chem. Soc .  2012 , 134, 17253−17261)

 

B.  X-ray photoelectron spectra were recorded on a VG EscaLab 220i spectrometer, using a standard Al Kα X-ray source (300W) and an analyser pass energy of 20 eV.  Samples were mounted using double-sided adhesive tape and binding energies are referenced to the C(1s) binding energy of adventitious carbon contamination taken to be  284.7eV.

 

C. XPS measurements were performed on a VG Scientific ESCALAB Mark II spectrometer equipped with two ultrahigh vacuum (UHV) chambers. All binding energies were referenced to the C 1s peak at 284.8 eV of the surface adventitious carbon to correct the shift caused by charge effect.  (Ref.: J. Phys. Chem. C  2017, 121, 4343−4351)

 

3. SEM和TEM

理论上应该给出: 仪器型号,工作电压,样品制备细节 等等

A. SEM images were collected on a Zeiss Ultra 55 SEM at 5 kV. Samples for SEM imaging were deposited on Si wafers. (Ref.:  J. Am. Chem. Soc .  2012 , 134, 17253−17261)

 

B.  TEM, HRTEM and EDX mapping were recorded on the FEI TITAN Cs-corrected ChemiSTEM  equipped with an energy dispersive X-ray (EDX) spectroscope, operating at 200 kV. The sample was embedded in epoxy resin, and then microtomed into sub-100 nm ultrathin films at room temperature. These microtomed thin film samples were first dispersed in deionized water and then deposited onto a carbon-coated copper grid for HAADF-STEM imaging and EDX mapping.  ( J. Phys. Chem. C ,  2017 , 121, 4074–4082 )

 

C. Samples of all catalysts were prepared for scanning transmission electron microscopy examination by dispersing the catalyst powder in ultra high purity ethanol. A drop of the suspension was then allowed to evaporate on a holeycarbon film supported by a 300 mesh copper TEM grid. Samples were subjected to chemical microanalysis and annular dark-field imaging in a VG systems HB603 STEM  operating at 300 kV. This instrument was fitted with a Nion aberration corrector and an  Oxford Instruments INCA TEM 300 system for energy dispersive X-ray (XEDS) analysis. ( Science 2006 , 311, 10)

 

4. 紫外可见漫反射光谱

UV-vis相对而言要说明的要少一些: 仪器型号,基底材料 等

A. A Varian Cary 100 Scan UV-visible system equipped with a Labsphere diffuse reflectance accessory was used to obtain the reflectance spectra of the catalysts over the range of 200-800 nm. Laboratory sphere USRS-99-010 was employed as the reflectance standard. ( J. Phys. Chem. C 2011 , 115, 20555–20564)

 

B.  Room temperature UV−vis absorption spectroscopy was conducted on a  Perkin-Elmer Lambda 950 UV−vis−NIR spectrophotometer using an integrating-sphere accessory. ( J. Am. Chem. Soc. 2013 , 135, 10411−10417)
