Jsm 6700f system

The electrochemical characteristics of ITO, PCL@PPy/ITO, Cu/PCL@PPy/ITO, and CuO/PCL@PPy electrodes were examined by using cyclic voltammetry (CV), amperometric response (i-t), and electrochemical impedance spectra (EIS). Electrochemical experiments were performed with a CHI660C electrochemical workstation (Chen Hua Instruments Co., Shanghai, China). A platinum electrode and a saturated calomel electrode (SCE) were used as auxiliary and reference electrodes, respectively. The morphologies of the modified electrode surface were analyzed by field-emission scanning electron microscopy (FE-SEM, using a JSM-6700F system from JEOL, Tokyo, Japan) and transmission electron microscopy (TEM, JEOL JEM-2000 FX, Tokyo, Japan). The X-ray diffraction (XRD) patterns of CuO/PCL@PPy and PCL@PPy were recorded on a D/Max 2500V/PC X-ray diffractometer (Cu, 40 kV, 200 mA, Rigaku, Tokyo, Japan), at a scan rate of 0.05° s⁻¹ with 2 ranging from 10° to 80°.

The scanning electronic microscopy (SEM) observation of broccoli samples was obtained using a JEOL JSM-6700F system (JEOL, Japan) to get SEM images. Before the measurement, samples were frozen in liquid nitrogen and dried in a vacuum freeze-dryer. Then they were coated with a thin layer of gold using a sputter-coater (Hitachi Science Systems, Japan).
The identified chemical composition, including water extracts, ethanol extracts, cellulose, hemicellulose, ASL, AIL, acetic acid, and ash of raw and SE samples, were determined according to the Laboratory Analytical Procedures of the National Renewable Energy Laboratory (NREL).
The FTIR spectroscopy study of raw and SE samples were measured by IS50 FTIR spectroscopy (Thermo Fisher, Massa, WA, USA). Each sample was prepared according to the potassium bromide technique. The region between 4000 and 500 cm⁻¹ was recorded with a resolution of 4 cm⁻¹ and 40 scans.
The thermogravimetric analysis (TGA) was performed with a TA instrument (Waters, LLC, New Castle, DE, USA) under a nitrogen flow. About 3 mg sample was placed in an aluminum crucible and heated from 30 °C to 600 °C at a speed of 10 °C/min.
