Biochemistry
Atherosclerosis causes millions of deaths worldwide and no known medications dissolve the plaques that build up inside arteries. Some proponents of alternative medicine claim that B-complex…
Chemistry
PURPOSE The project's purpose is to determine the number of particles in a mole, which is Avogadro's number. My hypothesis is that a mole of any substance contains a definite number of parti…
Biochemistry
Second Award
Green fluorescent proteins (GFP) are used as markers to image ß-amyloid plaques in Alzheimer's diagnosis, visualize cancer progression, and measure drug toxicity. However, the large size of…
Chemistry
Reed and Slater's rules do not accurately calculate effective nuclear charge in f-filling elements, and subsequent ionization energy values of these elements are difficult to find experiment…
Chemistry
Artemisinin, a sesquiterpene lactone isolated from a plant, is currently used as a superior antimalarial agent. Because of a recent discovery of artemisinin-resistant parasites, there is an…
Chemistry
Onion, ginger and tea, which are common foods, have antioxidant activity due to polyphenolic compounds such as flavonoids. In this study, I employed 1,1-diphenyl-2-picrylhydrazyl (hereinafte…
Biochemistry
Cattle breeding and feeding requires large areas of pasture and is dependent on climate and designed soil. The use of supplementation is often necessary and in general the agroindustrial res…
Biochemistry
Avian influenza, or bird flu, has been present since the early 20th century, with the first outbreak recorded in Scotland in 1959. Notable outbreaks occurred in the late 1990s and early 2000…
Biochemistry
Whether a diabetic or dieting, it's convenient to know how much sugar is actually in a food. Yes, the amount of sucrose is on the nutrition label, but what about the hidden sugar glucose tha…
Chemistry
In the evolving world of sustainable energy, hydrogen production by photoelectrochemical (PEC) water splitting stands out as a highly promising approach. Yet, challenges like limited light a…
Chemistry
Third Award
The accumulation of heavy metal ions in wastewater poses significant health and environmental risks as heavy metals are known to be toxic and bioaccumulate in living organisms. In recent yea…
Chemistry
Microalgae is one of the best biofuel candidates due to its ease of growth in many water environments, high lipid content, and lack of overlap with food production. The separation of microal…
Chemistry
