EXAMPLE 3

Instrumentation

The pH values of the buffer solutions were recorded using a dual channel pH meter (XL60, Fisher Scientific). All electrochemical measurements were performed using a CHI (760E) electrochemical workstation (CH Instruments, Austin, Tex.). Bare ITO and modified ITO were used as the working electrodes, Ag/AgCl was used as the reference electrode, and a platinum wire was used as the counter electrode. All electrochemical experiments were carried out at RT without deaeration. Images were obtained by using a field emission scanning electron microscope (FE-SEM, TESCAN LYRA 3, Czech Republic), and by using a transmission electron microscope (TEM, JEOL, JEM 2011) operated at 200 kV and equipped with a 4 k×4 k CCD camera (Ultra Scan 400SP, Gatan).

Example 5

Surface Morphology:

The morphologies of the prepared carbon materials were evaluated by both scanning electron microscopy (SEM, Tescan Lyra 3, Czech Republic) and transmission electron microscopy (TEM, JEOL, JEM 2011). The nitrogen-doped carbon prepared with or without activating agent was studied using SEM and TEM to ascertain the surface morphology of the prepared samples. FIGS. 5A, 5C, and 5E show SEM images of WANC, ZnNC, and NaNC SEM respectively, and FIGS. 5B, 5D, and 5F show TEM images of WANC, ZnNC, and NaNC, respectively. The figures mentioned above show the porosity improvement of surface by using an activating agent. FIGS. 5A and 5B demonstrate the bulk nature of WANC, which in turn explains the low surface area of carbon material. Using ZnCl₂as an activation agent increases the carbon surface topography, as shown in FIGS. 5C and 5D by the appearance of some small-sized pores. However, the use of NaHCO₃increases both the size and number of pores on the surface of NaNC carbon significantly, as shown in FIGS. 5E and 5F, and thereby increasing the specific surface area. That is consistent with the BET results discussed above. NaNC is composed of carbon nanosheets with numerous macropores, which correlates with the BET data discussed above.

The Mg(OH)₂NPs size distribution and the zeta potential were characterised by a Zetasizer Nano ZL instrument (Malvern, UK). A digital sonicator (Branson LTD) was utilized for dispersing the Mg(OH)₂NPs samples at 40% amplitude for 15 min at 2.0 s ON/2.0 s OFF pulse time. The thermogravimetric analysis (TGA) of Mg(OH)₂NPs was done using a Mettler Toledo TGA/DSC instrument under N₂ atmosphere. The crystallite size of Mg(OH)₂NPs at various temperatures was studied by X-ray diffraction (Siemens D5000 X-Ray Diffractometer at 0.15418 nm wavelength). A JEM 2011 (JEOL, Japan) Transmission Electron Microscopy (TEM) machine was used to characterise the particle size and the morphology of Mg(OH)₂NPs on the microbial cells surface. The JEOL JSM-6480 LV SEM instrument was utilized for characterising the morphology of Mg(OH)₂NPs with bacterial.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
