    The major bottleneck for lipid extraction from the wet microalgae is the low extraction efficiency, because of the immiscibility of nonpolar organic solvents with water contained in wet microalgae {Yoo, 2012 #31} {Kim, 2013 #118}. Traditional method for lipid extraction from dry biomass uses a co-solvent system, which consist of a non-polar solvent and polar solvent {Halim, 2012 #7} {Kim, 2013 #118}. When the co-solvent system is directly applied to wet microalgal biomass, the microalgal cells…

    Replication, first, came about because RNA was formed. This occurred because organic molecules on Earth were able to form ribonucleotides from the assistance of a clay catalyst. Eventually, these ribonucleotides formed RNA, which, through time, began to fold and replicate itself. As replication got faster, RNA's started to attract amino acids and hold them together. Bonds started forming, and proteins were able to be produced. As more years passed, a lipid membrane enclosed the structure to…

    conditions. Polymerization process can be adjusted and controlled in this method [39]. Materials and Methods for PLA synthesis 85 wt% of purity Lactic acid was used in the polymerization process, and Stannous octoate (Sn(Oct)2) was used as the catalyst. The polymerization process was carried out in a bench top system (Fig. xxxx ), consists with two flasks of 0.5 L, a mechanical stirrer, temperature control system, condenser connected to a vacuum pump. The reaction was conducted with and…

    better with the catalyst in a solid, ground up form. Even though the origin of it might not be completely true, Elephant toothpaste is a chemical reaction of hydrogen peroxide decomposing into water and oxygen gas. First grab a bottle of hydrogen peroxide that is at least 20%-30% pure for the ideal reaction, a small container of dish soap, a sheet of cardboard, a big bottle or beaker with a smaller mouth…

    They used TEM, BET specific surface area, X-ray photoelectron spectrum (XPS) and X-ray diffraction (XRD) to analyses physico-chemical properties of the catalyst. In addition, the catalytic activity, dimer inhibition, stability, and a kinetic model are analyzed to gives further evidence of the effectiveness SCWG of phenol. The results of their experiment show that Ru/CeO2 effectively assisted for converting…

    Assignment 1: Discussion Assignment Discussion Question 1 What is the difference between biochemical reactions in healthcare? Biochemical reactions occur as a chemical reaction, which naturally takes place in a living organism. It happens within a cell involving a catabolic reaction (breaking down of molecules) or a anabolic reaction (building up of molecules). The process involves a diversity of biomolecules interacting with one another in order to make up a new biochemical for a particular…

    they all tend to follow the same pattern. Social change happens as a result of oppressed people being so unhappy with their representation or the status quo, that a single catalyst can trigger them to take action against their oppressor. This essay will examine three of the stages of revolution which are: unhappiness, catalyst, and action. The historical focus will be on multiple revolutions during the enlightenment era and the literary focus will be on The Time of the Butterflies by Julia…

    The theoretical yield of acetylsalicylic acid in grams that should be obtained from the synthesis is 3.96 g. The closest experimental yield was obtained without using a catalyst for the reaction; with a yield of 3.67 g (93%) of crude acetylsalicylic acid and a yield of 3.39 g (86%) of recrystallized acetylsalicylic acid. These results are relatively accurate. Similar results were obtained for the experimental yield of the reaction catalysed by concentrated sodium hydroxide; with a yield of 3.38…
