Crystal

She rises from her chair and grabs a spherical green object from a nearby shelf. She sets it on the table with a thump. “Is that a crystal ball?” Will asks. The sound of his voice sends my heart into a downward spiral. Heat rises up my spine. Whatever is in the air in this place, it’s making my emotions go haywire. The crystal ball suddenly sparks into a cloud of green, producing sparkles within it. The woman laughs at the sight. “So much attraction! I’ve never witnessed the crystals igniting so fiercely before, darlings.” I shy away from Will, unable to face him. The crystals settle in the bottom of the sphere. “Exactly!” the woman say for the twelfth time. “Give me your hands, both of you! Quickly!”…

Fallingwater and Crystal Palace are two different buildings more than 100 years apart in architecture. These buildings have both made it through history of architecture by two famous architects Frank Lloyd Wright and Joseph Paxton. Their buildings display their sensitiveness to the natural environment. Also, how the compromises of these two buildings were based on their materials. Frank Lloyd Wright, Fallingwater, 1936, concrete, steel and stone, 5,330 square ft . This building is fascinating,…

Predecessor to the 80’s cult classic, The Labyrinth, The Dark Crystal was legendary puppeteer Jim Henson’s first attempt at creating a fantasy motion picture filmed entirely with intricate animatronics and puppets. The film is complete with heroes, villains and the other main elements of fantastical narratives as described by Russian scholar and folklorist Vladimir Propp in his breakthrough work, Morphology of the Folktale, which states that there is a sequence of 31 functions — certain actions…

create a model based off the crystal structure of the endonuclease domain of Bacillus subtilis MutL. This structure, in particular, exposes the presence of zinc in the binding site which is important for the MMR function of BsMutL in vivo. From there, they proposed a model describing the association of MutS and DNA polymerase III, β clamp with MutL, and nicking of a synthesized DNA strand. The importance of MutL is in its united effort with MutS to recognize mismatches and interactions of the β…

TITLE: QUALITATIVE PHASE IDENTIFICATION & CRYSTAL STRUSTURE ANALYSIS OF ISONICOTINAMIDE POLYMORPHS. INTRODUCTION The science of crystallography is important in stability studies and determination of solid state molecule or particles. Isonicotinamide (pyridine -4- carboxamide) is the amide form of isonicotinic acid which exists as different polymorphs. Isonicotinamide finds extensive use in the pharmaceutical industry because of its good anti-tubercular, anti-bacterial, anti-pyretic and…

The crystal size is also affected by the rate of cooling and larger crystals were shown to be formed when fat was cooled at a slower cooling rate83. However the samples were not subjected to changes in the rate of cooling in this study. At higher temperatures (or lower supercooling conditions) due to decrease in the driving force, less crystals are formed although the crystals are larger in size as compared to those formed at lower temperatures83. At lower temperatures, due to the higher driving…

Crystals form when a type of liquid cools down, and then hardens. The process when crystals grow is called "nucleation". Whenever a person eats salt, they are eating salt crystals. These crystals are called salt crystals. To make homemade salt crystals, the materials you need are hot water and salt. When dissolving salt in water, the salt is not changing its properties. This project will use different types of waters to see how many more crystals it will help grow. Dasani water is a brand of…

crystallization. The crystals were then put through the filtering apparatus to collect and dry all the crystals. About 3ml was used to rinse the crystals while in the apparatus. The crystals were then dried and the yield and melting point were taken. Results • Maleic anhydride = 0.4g (0.004 moles) • Ethyl acetate = 1ml • Hexane = 2ml + some to rinse crystals • Cyclopentadiene = 0.4ml (0.0048 moles) • Filter paper before = 0.18g…

Abstract: The objective of this experiment was to synthesize aspirin from salicylic acid and acetic anhydride. The general theory behind this experiment was to study the synthesis of a drug from organic materials. During the experiment, esterification had occurred between reactants salicylic acid and acetic anhydride. Then, phosphoric acid would catalyze the reaction and water would be added to decompose the remaining acetic anhydride. Through the process of filtration, aspirin crystals were…

The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…
