It is an element of chemistry with the atomic number 29 and the symbol Cu, which comes from the Latin "cuprum."
This welding method is valued for its multiple advantages, including operational efficiency, low environmental impact, energy efficiency, and the ability to restore metal structures without damaging them.

Also, the vertical heterojunction structure might be obtaining the maximum receiving area of the sunlight [12-13-14].
The structure and crystal of the powders were observed by (SHIMADZU XRD-6000, Japan) with CuKα radiation.
The structure, surface morphology, and optical nanocarbon thin films were studied using (XRD), (AFM), (FTIR), and (UV-Visible) spectrometer.
XRD analysis which has been obtained for the nanocarbon powder that confirmed the fact that the materials are hexagonal polycrystalline structure.

Our XRD analysis reveals a single phase without impurity and confirms the presence of orthorhombic structures with Pnma space group.
Generally, the production process can influence the material’s structure, related to its structure and microstructure.
Typically, t value of 1 will form a cubic crystal structure, t < 0.96 to form an orthorhombic crystal structure, and 0.96 < t < 1 to form a rhombohedral crystal structure [14,15].
All samples exhibit a single phase, as confirmed by XRD analysis, with an orthorhombic crystal structure in space group Pnma.

An establishment of electrostatic repulsion by grafting SO3- in molecule structure of PCA may result in a more negative zeta potential in the dispersion system.
It is a key technical method to maximize the targeted properties of PCA by modifying its flexible chemical structure [6].
CaCO3 may modify dispersion ability of PCA used in the present study for a change of cement chemistry of C3A hydration.

Oxidation of Manganese-Containing Aluminum Alloys studied by SEM Shawn C Wilson1,a, Anne Kvithyld1,b, Thorvald A Engh2,c, and Gabriella Tranell2,d 1SINTEF Materials and Chemistry, Industrial Process Technology, Trondheim, Norway 2NTNU Department of Materials Science and Engineering, Trondheim, Norway ashawn.wilson@sintef.no, banne.kvithyld@sintef.no, cthorvald.engh@material.ntnu.no, dgabriella.tranell@ntnu.no Keywords: oxidation, aluminum, manganese, SEM Abstract During remelting of aluminum manganese-containing alloys, some industrial experience has indicated a tendency toward increased oxidation losses when compared to unalloyed Al.
These oxidized materials were analyzed in the Scanning Electron Microscope using Energy Dispersive xray Spectroscopy (EDS) both for chemical composition and to analyze the structure of the oxide that was formed.
The oxidized materials were then analyzed in the Scanning Electron Microscope using EDS and Auger microprobe analysis, both for chemical composition and to analyze the structure of the oxide that was formed.

This leads to a conclusion that the PMMA alters the structure of PANI in a similar pattern as was observed with TiO2 nanoparticles.
The amorphous structures may be attributed to either the TiO2 nanoparticles being agglomerated within the polymer network or PANI being formed around the TiO2 nanoparticles.
PANI completely lost its electroactivity with no observable redox chemistry.
