Essay On Electron Microscopy

To understand the physics of ODT’s, these equations can be simplified further by using the rotating wave approximation [#Allen1987]. This approximation is valid when the frequency of the beam is relatively close to the resonance frequency of the atomic transition, thus \omega/\omega_{\textrm{A}}\approx1

To achieve this, the Heaven Lab uses computational chemistry and laser spectroscopy. For computational chemistry, they use ECP (Effective Core Potential) to correct the mass of the electron and the Darwin term for the actinide elements; following the theories of configuration interaction, density functional theory, and active space methods. Also, Thorium oxide (a specific actinide detectable through spectroscopy) has been tested using laser ablation of an actinide rod with Laser induced fluorescence, REMPI, PFI, PFI-ZEKE, and MCP. Ultimately, they have found that computational chemistry and laser spectroscopy are significant tools in identifying bonding properties of

1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth.  You might have to research this using the "T" button (Tell Me More About...)

Problem: How does the electronegativity of 1.25 mol/L of hydrochloric acid, 1.25 mol/L of sulphuric acid, and 1.25 mol/L of nitric acid, affect the rate at which magnesium will react at room temperature(21°C)? Background: A chemical reaction is the rate at which a substance goes through a change and it is transformed into another substance that has different compositions as well as properties.1 The rate at which a chemical reaction occurs depends on many factors, some of which include the concentration of a reactant2, temperature2, collision theory and electronegativity3. Concentration of a reactant effects the rate of reactivity.

The field trip to the American Museum of Science and Energy was a real eye opener to me. I enjoyed everything in the museum from the history of Oakridge and the cool science exhibits in the upstairs portion. Even the classroom activities were fun and engaging by showing many examples of the classes they have for elementary school students. I observed so many activities that could be integrated into any subject. One particular activity stood out the most. The Manhattan Project during World War Two was the most interesting. Learning about the Manhattan Project can be a combination of learning social studies concepts but integrating science concepts into to that particular lesson as well. Learning about the history of Oakridge and how people had to give up their land to the federal government could be the social studies portion. Learning about the bomb and how it was made could be part of the science portion of that particular lesson. If I had the opportunity to teach this lesson I would start off talking about the history of Oakridge. Giving examples of how people had to give up their land to the federal government for the war effort. I could paint a picture in students minds on how those people felt during that time. The class as a whole could participate in a reenactment that could portray how people came together during World War Two could also paint a picture in their minds. The building of the atomic bomb could be the science portion. Students would be learning about how

Our class gathered to observe the differences and similarities of life observable under a microscope. We wanted to study details of each slide to understand the larger picture of the life that they make-up.

When observing the electric bill, the three concepts that I learned from Chapter Seven: Electricity and Magnetism, is electrical power, electric potential, and Ohm’s Law.

I will then cut the potato chips with the help of the ruler and scalpel and name the three chips as test 1,2,3.

lution by less than one angstrom we can build a reliable atomic model for the rods and test the

“Moving from Max-Planck to Caltech is a great step in my Career. In Max-Planck, I used to study the ultrafast dynamics of matter but here I am able to see this dynamics. I am so lucky because working with Dr. Zewail not only inspired me in science but also in life”.

Nanotechnology is the development of atoms in a certain object. Nanotechnology has become very popular in the past few years. It is a way to rebuild the systems of life. To make systems move faster than ever before. Nanometer is about 10 times the size of an atom. Each of these has a huge effect on a system. Still there are questions out there that keep people wondering how important nanotechnology is to us. Many wonder how will it affect them and if we should continue this research. I myself wondered about nanotechnology. After researching this topic I have learned new and interesting facts to help me understand the entire concept.

B. Label the diagram of the pocket microscope in Figure 4. Use the following terms: eyepiece,

The electron microscope has become one of the most widely utilized instruments for materials characterization. An electron microscope is a scientific instrument that allows us to “see” objects so small that they cannot be seen in any other way. (CITE) Electron microscopes have allowed scientists to see individual molecules and atoms for the first time.
