compared to those of the fresh catalysts. Fig. 6 represents the TEM images of the fresh SCR catalysts. By comparing the EDS electron images of the catalysts, the Cu, Ce, and Nb particles on catalyst surface were distinguished. As shown in Fig. 6(a), copper may disperse as Cu2+ or CuO species on the catalyst surface. In Figs. 6(c) and (d), Ce and Nb were observed, because of metal oxides of CeO2 and Nb2O3 as shown in the XRD results (Fig. 2) and XPS data of Figs. 4 and 5. Comparing Figs.…

Introduction Copper is an element that can be typically obtained from copper ore (minerals) in the Earth’s crust(1). The ore is initially mined then goes through processes to recover copper(2). Copper is important as it many chemical and physical properties. Copper is a good conductor of electricity and is malleable (the ability to be bent) which is why copper is used in electrical wiring. It is also used in bronze and brass as an alloying agent(3). Chemists use a sequence of chemical reactions…

this experiment I will prepare a pure sample of an element (copper) by making a copper solution and then plating it out onto a more active metal. HYPOTHESIS: Because Copper is a more active metal than Iron, I believe the copper solution will plate onto the iron nail. PURPOSE: The purpose of this experiment is to observe reactions between metals depending on which one is more active and observe how to clean pennies, while making a copper solution. RAW MATERIALS: Two plastic cups Clover…

evidence. As previously stated, pollens prove that Oetzi had traveled up and down mountains before his death. He could have easily been chased up and down the mountains by his attackers. It is true that his copper bladed-ax was left behind, but his attackers might not have wanted to be identifiable. A copper ax would be too obvious for his killers to take. Being identifiable is something killers aren’t fond of. Nothing else valuable was left behind, meaning his attackers took anything else that…

iceman Otzi was assassinated by a group of people because they disagreed with him for some political reason. Otzi was discovered with many different items; with the use of these items we can infer why Otzi was killed. Among them was a copper-bladed axe. The copper axe he carried tells us that he was a of high ranking member of his village, the axe was a very powerful tool, as well as very rare, and cherished weapon; this was because of the time, energy, and resources it took to make one. Not…

On october 12, 2015 at or about 1102 hours i was dispatched to 1735 east young circle (publix supermarket), hollywood florida, in reference to a cellphone being taken. Upon further investigation it was later found that the cellphone would equal the amount to grand theft (over $300.00usd). Let it be also noted during the time of this investigation, i was working an off-duty detail at the above location. Upon arrival i made contact with the james othman, herein after referred to as the victim.…

Task 2 & 3: A. Pile the seaweed up on the tin lid supported on a tripod and begin heating with a strong Bunsen flame. It may have to be added a portion at a time during the heating, given the quantity to be reduced to ash. When all has been turned to ash, about a dessertspoonful of residue will remain. During the experiment we piled the seaweed into a tin container and placed it on top of a tri-pod which was placed over a Bunsen burner allowing the seaweed to burn and inevitably turn into ash so…

The Iceman better known as Otzi, was found buried within the ice of the Alps in the 1990’s. Ever since then people have tried to come up with theories for how Oetzi was murdered over 5,000 years ago. He lived at the end of the Ice age, and the beginning of the stone age. Otzi was five feet two inches tall and around forty to fifty years old. He had been a person of large significance during his time. Now in the 21st century we might have a clue as to why he died. Otzi died after retreating from…

Zinc is a wonderful choice to produce coinage since it is an abundance element with stable market pricing contrasted with numerous other coinage elements. In addition, they require less plating than other alternative base metals and its transportation cost are lower as well. Zinc comes in a phase of a solid with blueish-white color that exhibits a shiny luster and are neither ductile or malleable at room temperature unless the metal is being heated. One of the most important quality of zinc is…

Zinc is an essential mineral that can be found in many foods or dietary supplements. The mineral zinc is found in the periodic table with the symbol ZN and has an atomic number of thirty. Zinc is one of the more abundant elements in the Earth’s crust, the twenty-fourth most abundant, and it contains five stable isotopes. This mineral is also known as an essential trace element, meaning the human body only requires a small amount to be considered healthy. One of the health benefits of zinc…
