Infrared spectroscopy

The Greenhouse Effect This paper will revolve around the the Greenhouse effect and its effect on all things around it. Basically our environment has all these gases in it that are bad and good. The basic idea is that there are gases in our atmosphere that are unable to leave and it just continue to build indefinitely. The earth 's temperature then starts rising and rising and until it is said that eventually it will cause everything to waste away.. This gradual rise of the Earth 's temperature,…

(DeFries and Townshend, 1994). When light hits a leaf part of the light spectrum is reflected back to the observer (Peñuelas and Filella, 1998:1) and the NDVI is calculated using two variables from this light spectrum, the amount of red and near infrared reflection (NIR), as NDVI= NIR-red/NIR+red…

In our previous report, 21 we investigated the influence of formulation variables of clotrimazole-loaded cubic liquid crystalline nanoparticles. The composition of chitosan tailored cubic nanoparticles was optimized employing central composite design. The findings of Small angle X-ray scattering analysis confirmed the presence of D and P cubic phases in nanoparticles. Most importantly, considerable improvement in mucin binding was observed upon incorporation of chitosan owing to electrostatic…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. The structural evolution of FePO4 arises due to the deviation in temperatures from 294K to 1073K via a process known as the neutron powder diffraction. This happens when the temperature of 980K is reached to result in the α to β transition. There are however certain observations of discontinuities in structural parameters during this transition. The stark contrast is that during the α phase, there…

In the paper, FePO4 was studied in through neutron powder diffraction across a wide range of temperatures, and was found to have 2 states in general, the α (alpha) phase and β ( beta ) phase. The alpha phase exhibits a tetrahedral structure, which is similar to alpha quartz, and this occurs during generally low temperatures. In the case of this paper, the temperatures experimented on were between 294K and 1073K. The beta phase, however, is denser and exhibits a octahedral structure. The…

The FTIR spectrum of PVA/CS nanofiber was shown in Fig. 1(a). The band at 3255.32 cm−1 was corresponded to -OH stretching and the peaks at 1025.6 and 1450.04 cm−1 for the -C-O band. The peaks at 3445.32 cm-1, 2965 cm-1, 1640.01cm-1, 1598.7 cm-1, and 1361 cm-1 are due to amine NH symmetric vibration, C-H vibration, deformation vibration of the absorbed water molecules, stretching vibration of amino group of chitosan and vibration of C-H, respectively. The peaks at 890.1 and 1100 cm-1 was…

Light spectroscopy has become an incredibly useful tool in analyzing the structure and composition of compounds. Specifically, the principles of absorption, the process by which an electron absorbs radiation to excite from a lower energy state to a higher energy state, and fluorescence, the emission of photons when a material is subjected to radiation, allow for the identification and analysis of unknown concentrations of compounds.1 With that being said, the purpose of this experiment is to…

Since ancient Greece, humanity has become fascinated with science. The development of new technologies that will further the existence of mankind, has been the goal for many great scientists. Through centuries of experimenting, the mid-evil era of alchemy, and many years after, Chemistry became a topic of much importance. During the 1800’s, science had become one of the most rapidly growing fields as explanations for how things work, or the technological progression allowing us to discover more.…

ancient place or artifact. This technique wasn't that great with finding things and it took a long time. In 2011, most explorers turned to infrared satellite archeology. "Infrared stellite imagery detects these differences in density, revealing buried roads, tombs, and cities" (Juan De Los Santos, Anicent Civilizations, Paragraph 2). This quote means that the infrared technology highlights the density differences and shows that there is something different in the ground. When this happens, the…
