The Chemistry Of Material Chemistry - 1305 Words

Material chemistry is important as it leads to synthesis of advanced materials with new and superior properties and improved compositions. It is one of the integral parts of material science. It mainly deals with four components. (i)Materials, (ii) Synthesis and processing by different possible routes, (iii) Structure and Properties and finally (iv) Characterization and evaluation. Here the oxygen carrier chosen for the experiment is a mixed oxide of both Cu and Mn. Cu and Mn both belong to transition metal category with atomic numbers 29 and 25 respectively. Oxides of Cu and Mn are not at all toxic in nature and are environmental benign. Also they are less costly compared to other metal oxides. Copper oxides always show better reactivity and Manganese oxides have the ability to change to various oxidation states. Cu has atomic mass of both Cu and Mn oxides separately have showed high reactivity being an oxygen carrier, but literature shows that these oxides have limitations when us ed individually like limited recyclability, agglomeration, sintering etc. This lead to exploring the use of these single metal oxides in a mixed form. The three dimensional or geometrical arrangement of molecules or atoms as points in a specific form in space is called a crystal lattice. The smallest unit of a crystal lattice is called a unit cell. A unit cell is the smallest repeating unit of a crystal. The unit cells have different structures.

Socrates Vs. The Prince - 1842 Words

Socrates vs. The Prince Niccolà ² Machiavelli, a Florentine philosopher and political aficionado from the 16th century and Socrates, a classical Athenian savant who lived during the 5th century B.C., are both judged as being forefathers to modern western political science and thought. The two great men both came from erratic epochs within their respective nations of Italy and Greece: wars, transitions of power, and domestic conflicts left their countries void of sustainable leadership and in desperate need of a brighter future. But despite being from equally hopeless times, their theories on how their societies (and ultimately, future ones) should function in order to prosper, are divergent. In this essay, I will argue that Socrates would†¦show more content†¦He explains that, â€Å"...a natural difficulty which exists in all new dominions, because men change masters willingly, hoping to better themselves; and this belief makes them take arms against their rulers†¦Ã¢â‚¬  (Machiavelli 6). H ence, in order to be an effective ruler, a prince must overcome the aforementioned challenge. Moreover, he must also be pragmatic, unbound to moral consciousness or traditional scruples, heavy-handed, sleuth, defend his state with a domestic military (as mercenaries only provoke the weakening of a state), and take whatever lengths he must to solidify his strength and capabilities to rule, brutality being a welcomed measure so long as the â€Å"ends justify the means†, while also not oppressing the people. Socrates, a Greek philosopher often credited as being the â€Å"father of free speech†, would mostly likely disagree with Machiavelli’s perspective. Socrates is renowned as being a free thinker who was unafraid of questioning authority and making even the wisest men, leaders and commoners alike, unsure of their intelligence. He is sure of his talent, â€Å"...by a skillful speaker they mean one who speaks the truth. If that is what they mean, I would agree tha t I am an orator†¦Ã¢â‚¬  (Plato 25b). Socrates firmly believes in the power of subjective thought rather than pragmatism, as he always deliberates on what he calls the â€Å"unexamined life†, which in his opinion, is not worth living. Therefore, pragmatism, which is preferred by Machiavelli, is not his desired means ofShow MoreRelatedCompare And Contrast Socrates And Machiavelli1419 Words   |  6 PagesSocrates vs. Machiavelli: The meaning of truth As philosophers, both Socrates and Niccolo Machiavelli developed theories in response to the warring political environment around them.

Social Media Diet free essay sample

Social Media Twelve missed calls, seventy messages, and thousands of updates are what I came to after one of the loneliest days of my life. Twenty four hours doesnt seem like much but spending twenty four hours away from something so important to you makes it seem like an eternity. During my time away from my phone I found entertainment in things I usually dont do, such talking with my sister and just spending time with my family. I knew being home all day without a phone was going to be tough so I made some plans with friends to go out later in the night, but the time I did spend home alone was horrible. A day without my phone made me realize that I, like most of my generation, rely too much on our phones and electronics for our social needs. Not having my phone had a lot of obvious impacts on my life, but it also had a few that I had not thought about. For example, the night before I decided to go without a phone I realized I needed it for an alarm to get up before school. My mother woke me up the following day when she got up to go to work so acted as my alarm for the day. Obvious impacts were the fact that I couldnt text people I was used to talking to everyday of my life. Social media sites went out the window for the day as well as I only check them on my phone and didnt have access to them. My only real source of the outside world was the television. People dont often notice that social media sites and just plain texting help a person not feel so alone. Usually I go through my day never noticing the loneliness in my house, feeling Ake, Jancy normal because of people I text and talk to through the internet. On this day, however, I realized how truly alone I was in my home. I noticed the quietness and the lack of things to do around the house. I became a little afraid at the fact at how far everyone and everything felt from me and how vulnerable I was incase of an emergency. Texting and talking give us the illusion of having someone around us because of the immediateness of the conversation. Its not the same as real life but better than nothing. Throughout the day I found things to do here and there. I spent most of my day cleaning to keep myself busy. When my sister and family got home I talked to her and realized just how much she used her phone and how much I would have been using it if I had mine. During our conversations I would get annoyed that while I was talking shed be on her phone or while she was talking shed also be on her phone, but I slowly realized that she didnt do it out of disrespect but she was simply used to it. When I have my phone I do the same to her and we never notice simply because it is normal. In some way having a phone rationalizes being rude during a conversation because the act is mutual. It was a bit weird how I found entertainment in things I usually had no interest for such as going outside for a walk. I decided to go outside since being inside alone didnt help much and to my surprise I enjoyed it. Being outside without my phone felt freeing as if I had no worries and no one could ruin the moment because there was no way anyone could contact me. Anything that would make me forget about the fact that I couldnt use my phone suddenly became entertaining. I was looking for busy work or anything to get me through the day until it was time for me to go out because I thought going out would be no different without my phone. Ake, Jancy At night of that day I went out with my friends to a house party. Early in the night not having my phone wasnt a problem; I was with my friends and had no need for it. As it got later me and my friends spread out and went with different friends for a while, but when I wanted to hang out with a certain friend I couldnt text her to find her and I looked for her but still she was nowhere to be found. I eventually found her and it was late so I decided to go home. A problem that I had not realized was that I had no contact with my boyfriend to pick me up. I realized I didnt know his number by memory so couldnt even ask my friend if I could call him or anything and got a little scared since I didnt know how I was going to get home. I told my friend about my problem and she offered to give me a ride once her sister came home and my worries were alleviated. This experience made me realize just how much the modern world depends technology that our previous generation had no access to. It made me wonder how people lived their everyday life before cell phones and other things were invented. In a way its sad that we find it difficult to live without technology and how much weve come to rely on them for most of our everyday needs. Not having my phone for 24 hours was tough for me perhaps because Ive grown so used to having it when I needed. A friend of mine doesnt even own a phone and yet she gets through her day just fine because shes used to not having one. I feel more aware of how much I use my phone because of this experience and try not to rely too much on it so it isnt such of a big impact on my life.
