R L Timings describes materials as being a vital part of the evolution of mankind. He stated that our ability to use and develop materials to satisfy a human requirement is what really set us apart from other animals. This started from building weapons by manipulating stone and wood to hunt and defend territory. He goes on to say this lead to building tools to cultivate land and to manufacture artefacts such as cooking utensils. He finishes this part of his writing by listing how materials have developed

developing the atom theory for several years. Finally, Ernest Rutherford results from all of his experiment now used in the physic and chemistry education. In addition, to regard him, his picture appeared in the $100 New Zealand Dollar. He is a very important person behind the development of modern science and will be remembered for a long time because of his effort to discovering the theory of radioactivity, found the segment direction from his radioactivity experiment, and dissecting the atom.

Chart 1 describes the structure of the key components and overall reaction pathways of the present photocatalytic CO2 reduction based on a TiO2 hybrid system with an antenna and Re-based molecular catalyst; : the antenna, is (E)-2-cyano-3-(5′-(5″-(p-(diphenylamino)phenyl)thiophen-2″-yl)thiophen-2′-yl)-acrylic acid (Dye);, molecular catalyst (ReP), is fac-[Re(4,4’-bis(diethoxyphosphorylmethyl)-2,2′-bipyridine)(CO)3Cl];, and the electron donor (ED), is 1,3-dimethyl-2-phenyl-1,3-dihydrobenzimidazole

oxygen atoms together. The ground level ozone which is called the troposphere is considered an air pollutant that forms in the presence of sunlight from other pollutants in our atmosphere but the ozone layer that is up in the Earth’s upper atmosphere which is called the stratosphere which protects us from the sun’s harmful rays by filtering the UV light. The stratosphere is formed naturally and acts like the Earth’s sunglasses. The next thing that I learned about in this class was about atoms. Atoms

The Rosetta/Philae mission was an international space mission sent to study the small icy worlds that are comets. Specifically, the target of interest for this mission was the comet 67P/Churyumov-Gerasimenko. The spacecraft was launched in 2004 and arrived at the comet 67P/Churyumov-Gerasimenko on August 6, 2014. This space mission was unlike any other because this mission marks the first time in spaceflight history that a spacecraft entered orbit around a comet and deployed a lander to the comet’s

Nanoscience is the branch of science which studies the phenomena on materials at atomic, molecular and macromolecular scales, where the properties can differ very much from that of bulk materials. Nanoparticles are like a bridge between bulk materials and atomic or molecular structures. Despite of its size, the bulk materials possess constant physical properties. But at nano-scale size dependent properties are generally observed. Hence in general the properties of materials change as their size approaches

“Everything is energy and that’s all there is to it…” -Albert Einstein. For some of us the innovative method of hydraulic fracturing in the energy sector is a dream come true. To others, it is a nightmare. Often the word ‘fracking’ itself raises a lot of concerns, protests, and controversies. Environmentalists and the general public who are not aware of the facts and statistics about fracking, what’s called the bigger picture, often tend to think that fracking is a major concern and its impact on

4-1 The high concentration of urea might unfold proteins because urea is a very good hydrogen donor and hydrogen acceptor. Urea molecules are basically able to fit in between hydrogen bonds and eventually destabilize the structures of the proteins. 4-6 A. If you were to have a feedback inhibition from Z that affects BC it would mean that there would be an increased pathway form BXYZ. B. If you had a feedback inhibition from Z that affects YZ would keep the amounts of X and Y the same but

Electrophilic Aromatic Iodination of Vanillin Purpose: The purpose of this laboratory experiment is for an aromatic compound to undergo an electrophilic substitution reaction. To carry this out, our method combines sodium iodide and common bleach as the oxidizing agent in aqueous alcohol as the solvent. Balanced Chemical Equations: Physical Properties: Name of Chemical Chemical Structure Molar Mass (g/mol) BP/MP (ºC) Density (g/mL) Mass/Vol. Used Purpose 3-methoxy-4-hydroxybenzaldehye

\chapter{Event Selection}\label{Ch:BDTSelection} The measurement of the intrinsic electron anti-neutrino ($\overline{\nu}_e$) component in the muon anti-neutrino $\overline{\nu}_{\mu}$ T2K beam is crucial for the oscillation analysis, as it represents the largest irreducible background for the ($\overline{\nu}_{\mu} \rightarrow \overline{\nu}_e $) appearance measurement at Super-Kamiokande. Furthermore, the near detector number of $\overline{\nu}_e$ events $\text{N}_{\text{ND}}$ is used to constrain
