Copper Iron Alloy Of Different Thickness By Electrodeposition Technique

The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction was determined to be as following:-

We did this experiment to investigate about turning copper into gold. We did this experiment to find out that whether adding heat and chemical can change a substance’s colour. To find that out, we placed the pennies into the hot zinc powder and sodium hydroxide solution and added heat flames to the penny. After this experiment, we found out that adding certain chemicals and heat can change the colour of a penny from copper to silver to gold.

Here's a puzzler! If the outer core is clearly a liquid iron-nickel mixture, then shouldn't the inner core of the earth be liquid, too? The inner core should be hotter, and therefore it should be a liquid, too, right?

Atomic Force Microscopy was the method used to analyze samples inorder to identify their surface composition and determine their top structure. Compiled data was used to calculate the roughness of the sample.

The XRD results revealed the presence of magnetite nanoparticles and indicated their sizes from 30 – 40 nm (Figure 1a). SEM micrograph clearly illustrates that the magnetite nanoparticles sizes varied from 27.3– 34.62 nm (Figure 1b).

To optimize the properties of nano-material and atomic level needs an elemental probe with resolution of <1nm. The nano scale probe helpful to provide the reproducible control over defects.

Thin flakes of TMDs can be peeled off from bulk materials using adhesive tape, applied to the substrates and then identified by light interference using similar techniques used to develop graphene. Fig 6c shows a thin monolayer flake peeled off from the bulk material (Fig 6a) mechanically with the tape. Oxide nanosheets as well as other materials can be obtained using this method. Using the mechanical method of exfoliation helps to produce flakes of high purity that

Thin flakes of TMDs can be peeled off from bulk materials using adhesive tape, applied to the substrates and then identified by light interference using similar techniques used to develop graphene. Fig 6c shows a thin monolayer flake peeled off from the bulk material (Fig 6a) mechanically with the tape. Oxide nanosheets as well as other materials can be obtained using this method. Using the mechanical method of exfoliation helps to produce flakes of high purity that can be used for fabrication of individual devices, however, the size and thickness of the flakes produced by this method cannot be controlled. In recent research, lasers have been used to control the thickness of MoS2 flakes by thermal ablation, this method however has a lot of challenges attached to it.

Although the idea of luminescent SiCN structure was initiated in a previous master project where the ICPCVD system was employed, the parameters to fabricate luminescent SiCN thin films have not been established by the time of starting this thesis. Therefore, first, it was required to calibrate the deposition parameters to find the composition of the SiCN films exhibited luminescent. This involves a significant number of film depositions, the system maintained and troubleshooting of the plasma-assisted ultra-high vacuum deposition systems as well as some multitude characterization techniques. The results of this work have been accepted to publish in “Thin Solid Films” journal (#4) and were presented at the 211th Meeting of the

The M-H loops taken at room temperature for Co0.6Zn0.4PrxFe2-xO4 (x = 0.0, 0.025, 0.05, 0.075, 0.10) compositions as a function of applied magnetic field H are shown in Fig. 8. From these loops, saturation magnetization (Ms), remanence magnetization (Mr) and coercivity (Hc) were measured, shown in Fig. 9. It can be observed that all the samples have the lower values of Hc (few hundred Oersted), thereby indicating the soft magnetic nature of these samples. Moreover, with thesubstitution of Pr3+ions, Hc of the samples enhances, whileareduction in MS and Mr have been observed.

Raman spectroscopy and Raman microscopy will be utilized as major experimental methods throughout this project. Films with different flavors (multi-layered) will be divided into different parts and will be tested and imaged to see if there is any flavoring component on each cell part of the film.

The formation of nanocrystalline ZnO films was confirmed by using X-ray diffraction. XRD patterns of simple glass substrate and ZnO coated glass substrates were shown in figure 3(a) and (b-d), respectively. The amorphous behavior of glass substrate with a continuous curve ~20˚ to 35˚ in 2θ range was depicted in ‘figure 3(a)’ and was clearly evidenced in ZnO coated substrates. A comparatively low intensity and broadness in diffraction peaks was observed in single layer deposited ZnO thin film ‘figure 3(b)’, which revealed that film consist of coarse fine grains with nanocrystallinity. It was observed that the peak intensities gradually increased from triple ‘figure 2(c)’ to five layers ‘figure 2(d)’ deposited ZnO thin film and hence

FESEM images of Co-Ni-P film electrodeposition without the effect of magnetic field (a) and with magnetic field strength of 0 T (a), 6 T (b) and (c) 12 T (D. Li et al., 2016).

With advent of scientific research and technological interest, multiferroic materials have drawn much attention for foundational physics, technological application in possible miniaturization and integration for multifunctional devices (e.g. magnetic field sensors, multiple state memory element, transducers, actuators, broadband magnetic sensors, non-volatile memory elements, oscillators, phase shifters, electric field controlled ferromagnetic resonance devices, switching devices, modulation of amplitudes, filters, waveguides, spin wave generation, energy harvesters, magnetic recording read heads, random access memories, RF resonators, tunable inductors, and ME antennas) [1-11]. The most intriguing characteristic of multiferroic materials

Nanoscience is a rapidly-developing field that covers a wide-range of application in a large variety of areas of science and technology. It is a phenomenon and manipulation of materials at atomic, molecular and micro molecular scales, where properties differ significantly from those at a larger scale. The subject nanotechnology deals with study of manufacturing and manipulation of matter at nano-scale in the size range of 1-100 nm in any of the one dimension of the object which are called as nanoparticles (Rajan, 2004). Nanoscience and nanotechnologies are widely seen as having huge potential to bring benefits in areas of interfacing physical, chemical, medical, biological, agricultural, environmental, and engineering sciences with myriad
