    1. Color Color is a piece of the electromagnetic range and has dependably existed, however Sir Isaac Newton gave the first clarification of shading in 1666. Newton passed slender light emission daylight through a crystal situated in a dim room. Obviously all the noticeable range (red, orange, yellow, green, blue, indigo, and violet) was shown on the white screen. Individuals as of now realized that light went through a crystal would demonstrate a rainbow or noticeable range; however Newton 's…

    The purpose of this experiment was to use aldol condensation methods to synthesize colored cyclopentadienone and then UV/VIS spectrophotometry to characterize the dienone structure synthesized. The information gathered from the UV/VIS analysis was then compared to a computer model of the desired product to analyze the optimal 3D structure of the dienone. The base catalyzed condensation reaction was used to form the product for analysis, followed by vacuum filtration to recover the product. Both…

    UVB’s 1. The sun shines on the skin. 2. The UVB light interfaces with a form of cholesterol in the skin called 97-dehydrocholesterol. 3. This is synthesized into pre-vitamin D3, which is immediately converted into vitamin D3. 30 minutes of midday sun in a bathing suit, and you’ve absorbed up to 20,000 IU of vitamin D. Whether you spend half an hour in the midday sun or take 2 10,000 IU of vitamin D3 in tablets, it’s then transported to the liver where it’s turned into D25 for storage. These…

    Abstract In this paper CuO-NH-NH2 nanoparticle was synthesized and used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction (XRD) were used to characterize the nanoparticle. Direct Red 80 (DR80) and Direct Green 6 (DG6) were used as anionic dyes. The effect of adsorbent dosage, dye concentration and pH on dye removal was evaluated. Kinetic…

    When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

    Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

    Hooge’s relationship is an empirical relationship based on a large collection of data obtained for flicker noise in semiconductors and metal films. According to this model, the PSD of flicker noise is given by, S(f) = γHV 2 Ncf α Where Nc = ncΩ is the number of free charge carriers in the specimen,nc is the charge carrier density and Ω is the volume of specimen.γH is the Hooges constant, a parameter which characterizes the noise levels of a particular system. The initial value of gamma is…
