Infrared

system in which certain gases in the Earth’s atmosphere trap infrared radiation emitted from the Earth and re-radiate it in all directions. This causes additional heating of the Earth. As the radiation from the Sun is absorbed by the Earth’s surface, the energy is converted to thermal energy. Then, the Earth radiates lower-energy infrared radiation back out to the atmosphere and space. The Earth’s atmosphere and clouds absorb this infrared energy and radiation directed from the Sun by greenhouse…

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…

The Huygens probe was engineered to fulfill all objectives regarding Saturn’s largest moon, Titan. The probe was made to withstand landing and collect as much information as possible. The design enabled the probe to brake while descending into Titan’s atmosphere followed by parachuting the remaining spacecraft equipped with instruments to the moon’s surface. Engineers were uncertain where the landing site would be and enabled the probe with different features making it capable of landing on…

the scientific evidences that have shown the effects Global Warming has caused. The Earth naturally keeps its temperature within a suitable range for all living species, so they are able to adapt and survive. This happens by the Earth trapping some infrared waves in its atmosphere. This is needed in order for the Earth to be able to keep the temperature at its…

2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol by using the Grignard reaction. The product is then determined by spectral and physical…

What are pests? ‘a plant or animal detrimental to humans or human concerns (as agriculture or livestock production)"; alternative meanings include organisms that cause nuisance and epidemic disease associated with high mortality.’ In short they are troublesome and are the reason for unhealthy crops and dangerous food. What are pesticides? ‘A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests.’ Pesticides are extremely…

Pulse oximetry is a noninvasive procedure that is used to measure the oxygen saturation level of the newborn (Pillitteri & Pillitteri, 2013). The device used in pulse oximetry readings contains two diodes that release equal concentrations of red and infrared light concurrently into the tissue bed the electrode is secured (WHO, 2011). The reading that is displayed is the proportion of reduced hemoglobin and oxygenated blood that is calculated and displayed indicating the oxygen concentration…
