SCI論文寫作之Experimental section(一)

Experimental section是SCI論文寫作中最簡單的一個部分，不過也挺有意思的，它有意無意之間可能會反映作者的心態與素養。今天先從簡單的開始吧，給大家總結下Experimental Section裡面儀器表徵部分的一些寫法，大家應該用得上，不過不建議大家直接用哈，最好稍微有點變動。

基本介紹

Experimental section裡面的儀器表徵部分（Characterizations）主要是跟讀者交代本文所採用的是哪種儀器，使用的什麼條件，有什麼值得注意的問題等等。不過，每個人嚴謹的程度不一樣，文中所給出的信息的全面程度也會不一樣。在這裡，還是建議大家儘可能寫得細緻一點,。今天給大家分享一些General的寫法。

以下內容藍色部分可以作為模板

1. XRD：

理論上應該給出以下信息：儀器型號，工作電壓和電流，靶材，步長等。

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 =0.5°, λ = 1.541?, step size= 0.5°, 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）

當然，你真要寫得簡略點，審稿人也不太會計較

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

理論上應該給出：儀器型號，X射線源，荷電校正的標準等等

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

理論上應該給出：儀器型號，工作電壓，樣品製備細節等等

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. 紫外可見漫反射光譜

UV-vis相對而言要說明的要少一些：儀器型號，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. C2011, 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)
