Study of magnetic and structural and optical properties of Zn doped Fe3O4 nan...Nanomedicine Journal (NMJ)
Objective(s):
This paper describes synthesizing of magnetic nanocomposite with co-precipitation
method.
Materials and Methods:
Magnetic ZnxFe3-xO4 nanoparticles with 0-14% zinc doping (x=0, 0.025, 0.05, 0.075, 0.1 and 0.125) were successfully synthesized by co-precipitation method. The prepared zinc-doped Fe3O4 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM) and UV-Vis spectroscopy.
Results:
results obtained from X-ray diffraction pattern have revealed the formation of single phase nanoparticles with cubic inverse spinal structures which size varies from 11.13 to 12.81 nm. The prepared nanoparticles have also possessed superparamagnetic properties at room temperature and high level of saturation magnetization with the maximum level of 74.60 emu/g for x=0.075. Ms changing in pure magnetite nanoparticles after impurities addition were explained based on two factors of “particles size” and “exchange interactions”. Optical studies results revealed that band gaps in all Zn-doped NPs are higher than pure Fe3O4. As doping percent increases, band gap value decreases from 1.26 eV to 0.43 eV.
Conclusion:
These magnetic nanocomposite structures since having superparamagnetic property
offer a high potential for biosensing and biomedical application.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Material
• Threaded tensile bar
• Standard Test Methods for Tension
Testing of Metallic Materials.
ASTM E8/E8M
threaded tensile
3. Characterization Properties
• Surface structure: Surface morphology, topography
and crystallographic information.
• The fracture mechanics
• The composition
5. Technique 1: X-Ray Diffraction (XRD)
• Analyze and identify unknown materials
• To identify the composition of the specimen
• This identification is performed by comparison of the
diffraction pattern to a known standard or to a
database such as the International Center for
Diffraction Data's Powder Diffraction File or the
Cambridge Structural Database (CSD).
• Non-destructive technique
• Sample preparation is easy and fast.
DEFINITION:
Analytical technique used for phase identification of a crystalline material and
can provide information on unit cell dimensions.
6. Technique 2: Scanning Electron Microscopy (SEM)
• High resolution and large depth of field: Produce a
good image (3D)
• Analyze how the atoms are arranged in the object
• See the fractured surfaces of a specimen.
• Specimens must be conductive when examined using a
SEM to provide conducting path to earth.
• For non-conductors it is required to be coated when
using a SEM.
DEFINITION:
Technique that uses an electron microscope that produces images of a sample by
scanning the surface with a focused beam of electrons.
7. Results : XRD
• The composition is identified by comparing the XRD pattern to the
library of known patterns.
• Aluminum, Silicon and Nickel.

8. Result: XRD
• The intensity is proportional to the number of x-ray photons
of a particular energy that have been counted by the detector
for each angle 2θ.
• Each peak or reflection in the diffraction pattern corresponds
to the x-rays diffracted from a specific set of planes in the
specimen.
9. Aluminum
• 9 peaks: low with symmetry
• 9 different positions: 9 different crystal structure of Aluminum
• For example, the miller indices or hkl plane of the highest peak would be Al[111]
which it is either be a FCC or cubic structured. Meanwhile, the lowest peak would
be Al[420]
• Highest peak (intensity of 100%), it proved that the quantity of the Al [420] is
higher compared to other different Aluminum types.
13. Scanning Probe Microscopy (SPM)
• Expensive tip
• Tip must be as sharp and narrow as possible
• It requires extremely clean surfaces
• Sample surface must be able to conduct
electricity
14. Optical Microscopy
• Low magnification and small depth of field: Small resolution
• Only able to view objects in the range of 1 mm - 300 nm.
• Requires proper and sample preparation
15. Optical Microscopy
• Preparation of the specimen : Change the microstructure of
the material (through heating, chemical attack, or mechanical
damage).
• The amount of damage depends on the method by which the
specimen is cut and the material itself. For example, cutting
with abrasives will cause high amount of damages.
• Friction heat can damage specimens and generate artifacts in
the microstructure.
19. Raman spectroscopy
can identify unknown materials from their
unique Raman spectral fingerprints, typically
using databases of known spectra
involves the interaction of light with matter
20. • study changes in the details of the spectrum
such as the height, width, and position of the
Raman bands
• In solid-state physics, Raman spectroscopy is
used to characterize materials, measure
temperature, and find the crystallographic
orientation of a sample
22. • The XPS instrument measures the kinetic
energy of all collected electrons. The electron
signal includes contributions from both
photoelectron and Auger electron lines.
• widely used technique for studying the
properties of atoms, molecules, solids and
surfaces. It has been utilized for the study of
free atoms, free molecules, and the bulk
properties of solids and liquids.
