Improved Surface Quality with TiN‐Coated Tool

“…The small white particles observed on the surface of the coated tool are associated with the presence of the TiN compound. [9,10] In Figure 2b, it can be observed that there are white droplets and pits on the surface of the TiN coating. This is due to the intrinsic characteristics of the deposition technique.…”

Preparation of a Cu-Doped Graphene Oxide–Glutamine Nanocomposite for Supercapacitor Electrode Applications: An Experimental and Theoretical Study

“…The energy crisis is, with the massive consumption of fossil fuels, one of the major issues in modern society. , Therefore, energy storage must be demanded, which could reduce the gap between its utilization and turnout. − Supercapacitors are a kind of clean and sustainable energy storage devices that have become a hot topic due to their high power density, fast charge–discharge cycles, eco-friendliness, wide operating range, and long cycle life. − Supercapacitors have been investigated for different energy storage applications, such as larger-scale electrical lines, transportation (electric buses, trucks, and heavy-duty vehicles), power supply backup, memory backup, portable devices (phones, digital cameras, and laptops), wearable electronic devices, smart grids, satellite applications, and military applications. Therefore, they play an important role in people’s daily life. , They can store energy in two ways: (i) oxidation–reduction (redox) reactions between the electrolyte and electrode (pseudocapacitors) and (ii) ion adsorption on the electrode (electrochemical double-layer capacitors). , …”
