The development of simple methods for generating molecular complexity with defined stereochemistry from easily accessible starting materials became significant and fascinating over last few decades. A simple methoxyphenol is found to be most appropriate precursor for generating wide range of complex cyclic and acyclic architectures. Several chemical1-5 and electrochemical methods6 have been used for the umpolung of electron-rich nucleophilic 2-methoxyphenols and 4-methoxyphenols to electrophilic…

1. What is macro photography?: Macro photography is when you take a photograph of a very small object very close up. 2. What are the advantages and disadvantages of macro lenses?: Macro lenses can magnify a small object to be life size without any other attachments but they are very expensive 3. What are extension tubes? What are the advantages and disadvantages of this piece of equipment?: Extension tubes are hallow tubes placed between the camera and the lens. They aren't as good as macro…
When looking at a flashlight, it can be determined that the flashlight itself resembles a parabola. Flashlights are supposed to be able to focus on a single point, which is infinitely small. Since a flashlight is supposed to mirror a parabola, the flashlight has similar components as a parabola. The filament, which is the part of the flashlight that gives light, resembles the focus on a parabola. The filament is a three dimensional object so it is infinitely larger than a point, yet the filament…
Richard Misrach is an American contemporary photographer that focused mostly on landscape photography. One of his main goals was to capture the effects of the society on nature. (Artnet) Misrach’s work consists mostly of nature and landscapes. His photo I have selected is of the aftermaths of a forest fire at Yosemite. It is unknown weather the fire was man made or from natural causes but it does make one think of the effects they might be having on this gorgeous earth. Misrach’s Yosemite (Burnt…
II INTRODUCTION The purpose of this lab was to demonstrate and observe the effect a large focal spot and a small focal spot will have on the resolution of the image. Chapter 3 of Practical Radiographic Imaging states that resolution is “the ability to distinguish two adjacent details as being separate and distinct from each other” (Carrol, 2007, p. 48). This definition of resolution helps to explain what will be looking for to retrieve the data for this lab. As stated in Chapter 16 of…
Experiment #6: Polarimetry Resolution of (∓)-Racemate: (∓)-ɑ-Phenylethylamine OBJECTIVE All chiral molecules have a mirror image of themselves. While they have the same physical properties, they interact with other chiral molecules completely different. Since there are many chiral molecules in organics, this can lead to the need to make optically pure products. If the chemist does not, it can lead to many problems including death. In this experiment, the separation of two enantiomers was…
Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…
SHAH How to do HDR photography (lions) HDR Photography HDR (High Dynamic Range) photography is a form of image processing that uses a series of images captured at different exposures to produce one, amazing photo. The dynamic range is a term used to infer to the ratio of darkness to the light. The idea is usually to compress the compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital…
