Yoshida et al.‚ Flexibility of Hydrogen Bond and Lowering of Symmetry in Proton Conductor‚ Symmetry 2012‚ 4‚ 507-516. Paragraph 1 In this paper‚ we take a look at the different phases of the Cs3H(SeO4)2 polymorphs. There are 3 different phases that is observed and each of them is influenced by the temperatures. In addition‚ in each phase‚ the polymorph exhibits different crystal structure. At the room temperature of 298K‚ it will be in phase 3 whereby it takes the structure of monoclinic-C2/m

Niels Bohr’s model of the hydrogen atom‚ was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns‚ scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form‚ and then leaving the gas in the form of light. He figured the light rays to be quantized‚ meaning only certain frequencies of

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

Stratford-upon-Avon. Analyzing this short story written by Arthur C. Clarke‚ one can conclude that he must enjoy writing about scientific breakthroughs and he utilizes vocabulary that is very different from most authors. The entire story is about a hydrogen bomb destroying the city of Stratford-upon-Avon. The story is told a few days after the incident. The story describes the state of the small town after the bomb was dropped on it. The bomb is destructive‚ there are no humans‚ animals or even dialogues

This could then be focused by the student as follows: “Does ethanol concentration affect the activity of bovine catalase?” It is not sufficient for the student merely to restate the research question provided by the teacher. Variables are factors that can be measured and/or controlled. Independent variables are those that are manipulated‚ and the result of this manipulation
