from the lab notebook. If both melting point are in the same range, the product made is determined to be pure. A pure acetylsalicylic acid will have a melting range of 134-136C. Finally, an infrared spectrum will be recorded for the product. The infrared spectrum of the product will be compared with an infrared spectrum of a pure acetylsalicylic acid. According to the methods described in the lab manual (INSERT LAB MANUAL CITATION HERE), 150 mg of salicylic acid was added into a test tube.…

"These are truly massive cyclones, hundreds of times stronger than the most giant hurricanes on Earth," said Kevin Baines, Cassini scientist on the visual and infrared mapping spectrometer at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Dozens of puffy, convectively formed cumulus clouds swirl around both poles, betraying the presence of giant thunderstorms lurking beneath. Thunderstorms are the likely…

division where it will be transmitted after analysis. 4. The Detector: The beam will pass through the detector for the measurement. 5. The Computer: The signal will be interpreted and sent to the computer where the transmission will happen. The final infrared spectrum is present for interpret. 3.4 Compaction The synthesized powder is pressed into a disc shape with the diameter is twice to the thickness. The compaction is the process after the blending and mixing process. The composition of…

While cookies are baking in the oven, heat transfer occurs to make them bake correctly. As said by the author Nora Fulmer, heat transfer is the process where an item comes into contact with a heat source and exchange thermal energy between two objects. It is a complex process that removes bacteria, while cooking food. Heat energy is created and transferred when food becomes hot, its molecules absorb energy and begin bouncing off each other. The first type of heat transfer is conduction.…

1. How is Kroger leveraging Technology? Kroger is leveraging technology by utilizing up-to-date ideas to make the stores efficiency better. The first thing is the infrared sensors. These are used to control how many customers are coming into the store and can tell when people are getting in line to checkout. They also have sensors to keep track of the temperature of foods in the store, like produce and met, that need to be checked on regularly. They started using online ordering system, Click…

Is it possible for a star to burn cold? The answer is not as simple as you may think; while all sars burn hot, there are some cold enough to touch (if you survive the vacuum of space). In 2011, NASA’s satellite WISE discovered six Y-Dwarf stars burning as cold as ice, not even forty light years away from our own sun. This type of star is often referred to as a Brown Dwarf, or a failed star. There are three types of Brown Dwarfs; L-Dwarf, T-Dwarf, and Y-Dwarf, the Y-Dwarf being the coldest.…

Characterizing the IR Reflecting Properties of Pigments for Cool Roofs Introduction The sun energy reaches earth as UV visible and Infra-red radiation. UV radiation is an invisible part of electromagnetic spectrum. Only 5 % UV from sun reached the surface is play the major role to the degradation of coating .Visible light wave (295-400 nm) seen by human eyes. Around 50% of the suns energy occurs in this region which gives the perception of colour.45 % of total solar energy is in IR region…

OVERVIEW Four ablations will be done in ex vivo bovine for each flow rate. There will be three different flow rates: 0 mL/min, 860 mL/min, and 1000 mL/min. These flow rate were chosen based on hepatic flow rates of humans in the supine position (Brown et al. 1989; Leen et al. 1992). Each ablation will be performed at 40 watts for 2 minutes for a total of 12 ablations. The average area of a 30ºC and 50 ºC contour at the end of the ablation will be used to characterize the size of the ablation…

higher stability and can be functionalized with drugs for targeted drug therapy.1 Spherical gold nanoparticles and gold nanorods have been used in biomedicine. However, nanorods have gained importance due to its high light backscattering in the near infrared area, which give more insights in the field of optical imaging. The gold nanorods used in imaging had an advantage over enhanced imaging techniques because others convert soundwaves to image or use magnetic resonance imaging which cannot…
