There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…

1. Fit the stem of a funnel inside the short end of a straw. Push the funnel in as far as it will go. Securely tape the straw to the funnel. Repeat for the second straw and funnel. 2.Push a straw-funnel assembly through the hole near the bottom of each container so that the funnels are on the inside of the containers. Adjust the straw-funnel assemblies so that the funnels face up. Put some modeling clay around the hole, on the outside of the container, to hold the funnel in place. 3. Start by…

More conjugated compounds absorb higher wavelengths/lower energies because as the wavelength increases the HOMO/LUMO gap (ΔE) decreases which is due to the compression of multiple molecular orbitals (ψ). According to Klein, the Ketchup stain (lycopene) on a shirt and upon application of bleach (NaClO), it breaks lycopene’s conjugation, therefore causing a decrease in conjugation; which directly correlates to the stain no longer being visible to the eye but when illuminating the shirt with…

and CO2, there is a compromise of lactate acid and acid- base balance from a high intensity exercise. The factors that avoid this change in the homeostatic limits are PO2 and PCO2, and pH. Which are maintained form increase in oxygen delivery to the alveoli and CO2 exhalation from the body (King, 2018). Acid- Base balance are affected by hydrogen ions which are formed from the lost of electrons. When a molecule releases hydrogen ion it is determined as acid, and when it is bind with hydrogen ion…

Introduction Ascorbic acid is a form of vitamin C that is used by the body as a means of promoting healing of cuts and wounds, as well as boosting the immune system and as such aiding in the fight against infections. Ascorbic acid does not occur naturally and is formed by carrying out a variety of chemical reactions on corn syrup. The chemical formula for ascorbic acid is C6H8O6 and is similar to glucose which has a formula of C6H1206, this closeness in structure allows most animals (excluding…

Acids and Bases are solutions, and can be found everywhere in the world. They can be found in food, drinks, around the house, and in the environment around you. Acids and Bases are used by people, animals, and even plants for many different purposes (Buthelezi et al. 634). A solution is a homogenous mixture, which is a mixture with a composition that is consistent throughout the substance (Buthelezi et al. 634). Solutions are comprised of the solute and a solvent. The solvent is the most…

of HBA and HBA-BMF. In Fig. 2a,terminal methyl group present in fatty acid chain show the peak at around δ = 0.9 ppm.31 The proton of −CH2− groups of the fatty acid backbone and terminal methyl group attached proton show the peak between δ =1.20−1.59 ppm.30 The peak at δ = 5.4 ppm is attributed to the protons attached to the olefinic carbon atom (−CH=CH−) of fatty acid,28 this peak provides the evidence of the presence of fatty acid chain of SO in the HBA resin. The peak in the range δ =7.3−7.5…

As identified in the previous studies mentioned by Knowler et al., (2002) and Gilles et al., (2007) metformin has shown to reduce the risk from progression of prediabetes to diabetes. Moin et al., (2002) case-control study looking at causality examined metformin prescription use for diabetes prevention in individuals with identified prediabetes over a three year period in 17,352 working-age adults. Of the total sample size on 3.7% of patients with prediabetes were actually prescribed metformin…

environment. It does so via the use of two-component systems, one of which is called PhoPR two-component system6. In order for Mtb to survive, it must synthesize its own biotin, an essential cofactor that is involved in the biosynthesis of some fatty acids (e.g. mycolic acid), from pimeloyl-CoA7. During infection, Mtb primarily resides in macrophages, which, normally,…

cellulose. The protists and prokaryotes can hydrolyze the cellulose, which the cow or termite can then use. Lipids A. Fats- A fat is made of a fatty acid and a glycerol. A fatty acid is a long carbon chain with a carboxyl group on the end. It is made up of C-H bonds. Glycerol is an alcohol. Fats are used for energy storage. Fats can store two times as much energy as polysaccharides. Animals use fat instead of starch because fats can store more energy with less space. The adipose cell humans use…
