Crystallization

Cat’s Cradle Kurt Vonnegut’s novel Cat’s Cradle is a satirizing of the Cold War and the possible catastrophic apocalypse brought on by moral ambiguous scientific innovations. One of Bokonon’s sayings explains why Vonnegut favors satire: “Maturity is a bitter disappointment for which no remedy exists, unless laughter can be said to remedy anything” (Vonnegut. 1963, p. 198). World War II brought rapid scientific advances and a state of political tension between the Soviet Union and the United…

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…

Introduction: Limonene is a terpene that can be isolated from orange peels almost 100% in the (R)-(+)-limonene form. The essential oil from the orange peel belongs to terpenes, which are compounds that are made up of two or more five carbon units, named isoprene.1 The limonene is a monoterpene, which means it is made up of two isoprene units. Natural products are related compounds formally derived from isoprene units are terpenoids.3 The skeleton of terpenoids may differ from strict additivity…

Nostalgia manifests itself in many ways; the art of calligraphy is essentially a nostalgic search of the lost totems. Chinese characters are not immutable. As a matter of fact, behind every Chinese character there is a history of evolution, from the ancient oracle bone scripts to modern simplified Chinese characters. In this way, every generation inherits the tradition of Chinese characters, and then overthrows the tradition. Before a nostalgic Chinese speaker can use the lost totems as…

INTRODUCTION For this essay, I will be reflecting on Sherry Ortner’s literature on key symbols. This essay will build on Ortner’s (1973) argument on key symbols in a culture, using my chosen key symbol Gaelic football to convey that this signifies a symbol of Irish culture. For this paper I empirically experienced in ethnographic fieldwork with an experienced individual in the realm of Gaelic football. Key information on interviewee This interviewee is male and his background with Gaelic…

recapture her, the death, and the judgement all are impurities in the community. To become sapphire, the mineral must be impure, otherwise it will remain a clear stone rather than a beautiful blue gem used in jewelry. After high pressure, re-crystallization, weathering, and exposure to impurities, a beautiful gemstone is revealed.…

Abstract: Chemiluminescence is an essential topic in the study of chemistry. The reaction involves mixing two chemicals were to form an excited (high-energy) intermediate that releases energy as light. This experiment first synthesized luminol by reducing 5-nitro-2,3-dihyodropthlazine-1,4-dione, using sodium hydrosulfite (Na2S2O4) and 3M sodium hydroxide (NaOH). The amount of luminol collected was 0.2693 g with the percent yield of 161%. The product of the first reaction was then used to…

After the mass of the crude product was measured, the recrystallization was done for more purification; the solution looked clear prior to it’s cooling to room temperature. After the solution cooled to the room temperature and vacuum filtration was done again on recrystallization product, the solution was a white shiny with crystalline solid appearance. The melting point of the Meta-Methyl nitrobenzoate product formed was at 76.2 ‐ 78°C. The appearances of the TLC for the crude product, starting…

corresponding to reflection planes of cellulose II: 1-10 and 110, respectively are presented3-4. Cellulose I is the most prevalent form in the nature and it occurs in two allomorphs Iα and Iβ. Cellulose II is the crystalline form that emerges after re-crystallization or mercerization with aqueous sodium hydroxide, and it is thermodynamically the most stable form. In cellulose I the chain orientation is exclusively parallel, whereas in cellulose II the chains are arranged in an antiparallel…

membrane of cells which has an unclear function. When the two interact, prion alters and converts part of the PrP’s helical shape to a sheet structure, and the process is repetitive. Prion forces the body to create more of the virus, resembling crystallization (Gale 2013). Prion is similar to the enzymes related to Alzheimer's and is not killed by ultraviolet radiation and resistant to heat, chemicals, and degradative enzymes. (Gale, 2012). Sporadic CJD can occur when prion switches to its…
