A chemist may be draw to the science because it contains physics and mathematics, with results clearly defined. On the other hand, biology can be messy, with fluids and disrupted bodies and patient suffering. For the nursing professional, there may be the temptation to define a physical process present in a patient as either biological or chemical. Technically, the definition for biology is simply the “scientific study of living organisms” (TheFreeDictionary.com), while chemistry is “a science that deals with the composition, structure, and properties of substances and of the transformations that they undergo” (Merriam-webster.com). However, the lines blur when ...

Introduction

Reduction reactions are very important in chemistry as they are effective processes for synthesizing new compounds from existing ones. In organic chemistry, a compound is said to be reduced if it acquires new hydrogen. There are diverse reagents for carrying our reduction reactions. Two of these are sodium borohydride (NaBH4) and lithium aluminum hydride (LiAlH4) - the latter is a more powerful reducing agent compared to the former. In this experiment, NaBH4 was used to reduce p-Nitrobenzaldehyde to form p-Nitrobenzyl alcohol. NaBH4was used over LiAlH4 in this experiment, because LiAlH4 would also reduce the nitro group of the aldehyde.

The United States during World War II had developed a massive new process for technical progress with an applied goal. That is to say, the Manhattan project which culminated with the building of the first ever Atomic bomb was a very important milestone. It showed that civilians and the military could work together for a common goal. While ...

It is not a secret that humanity on the path of development has created a lot of useful things, but for every successful invention there are many unsuccessful. The "Golden age" of mankind was the 19th century, when the invention has become a favourite pastime of many people. Some inventions did not have chances for success, because their authors were not able to understand the scientific principles underlying them. Other inventions were just a flight of fancy and were designed for entertainment. I believe that if we are able to do something, it does not mean that we have ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

INTRODUCTION

The United States and the then Soviet Socialist Republic, or USSR, had always had ideological differences underlining their relations. The US has always been the world’s champion of democratic ideals, while the USSR promoted the socialist ideology. In World War II, however, the two countries set aside their differences and formed an alliance with other countries to fight a common enemy: the Axis Powers that included Germany, Japan and Italy. The defeat of the Axis Powers resulted in power vacuums, which the two countries immediately tried to fill, thereby, resulting in a contest of superpowers. Suspicions of each ...

Introduction

The essay will compare the skepticism of two ancient philosophers concerning popular religious, spiritual and superstitious beliefs. The first philosopher we will look at is Lucretius who was a well-educated Roman popularly known for his poem “On the Nature of Things.” The second philosopher is Wang Ch’ung who was born in China and studied at Loyang academy in the capital.

1) Past events contribute to the present actions of a character: Dr. Manhattan The character Dr. Manhattan is shown as tremendously powerful, with godlike abilities, and has a decreasing capacity to relate to humans. In fact, for most of the story, the character is portrayed as trying to act as a demi-god, but somewhat failing at it, displaying at different times lust, anger, impatience, compassion, and other human traits. I posit the opinion that his aloofness and predetermination belief are not only due to his altered perception of reality – he sees the constituent particles of the universe – or of ...

Substance Dualism and Materialism: According to Descartes

René Descartes’ substance dualism is summed up in the most famous words used by many: “I think, therefore I am.” This is an indication of how he perceived the mind and the body – as two separate entities. His substance dualism can be summed up further in that, the farther the mind is moved away from the senses, the better the mind can understand the truths around its thinking. Thus, it means that, according to Descartes, the mind is separate from the body. In his reasoning, he regarded the material as separate from the mind. This forms the crux of ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Solar Energy

Solar Energy Background What can be more useful for humanity if not an unlimited power source, which we can use without any harm to the environment? Probably nothing, but solar power. Humanity has always tried to conquer the unlimited power of the sun – the history of solar technology dates back to the 7th Century B.C. and continues to this day. In the beginning, we tried to concentrate the sun’s heat by using glass, mirrors or other devices to light fires. From those times, we greatly progressed, but still we did not conquer this magnificent source of power. Why ...

That a man should hate oneself is a common phenomenon, which everyone experiences once in a while, because of people’s intrinsic flaws. These flaws ramify into people’s creations such that there is not one thing a man has created, which does not have to endure a measure of hatred from the rest of society. The creature in Frankenstein is no different from men’s inventions, whose hideous nature was not apparent at the time of their inception, and abhorred for what passed as evil yet not appreciated for the utility its creator envisaged. The guiding question for ...

Introduction

In August 1945, America dropped two atomic bombs on Hiroshima and Nagasaki, killing a total of 129,000 people. The two incidences remain the only known uses of atomic and nuclear bombs in history. The events brought to an end the World War II that had been going on for close to a decade. Paul Tibbets was the pilot of the plane that dropped the two bombs, and up to his death in ...

The Cold War alludes to to an economic, military and political conflict involving the Soviet Union and the United States from 1945 to 1991. After the Second World War, changes in general superiority led to complications which resulted in tensions between the two blocs. The United States was opposed to attempts by the Soviet Union to extend their territories hence leading into diplomatic tension, upgrading of security systems and proxy wars between the two great nations. The Soviet Union wanted to acquire Poland in addition to taking a share of Berlin. The then president of the United States, Harry ...

When considering nationalism and ultranationalism during World War II, I strongly believe that the United States were protecting and defending their nation. I strongly believe that nationalism is important because it helps a country become more united. People are more focused on one common idea and everyone is shooting for this common goal which seems to also increase patriotism. It is a positive impact on society in the United States. However, there were several countries who were involved in World War II and it is imperative to look at the involvement that each country had to truly understand nationalism ...

Abstract

In this experiment, benzene was treated with hydrogen in the presence of Pt/SiO2 as an example that can be applied on industrial operations to show that the most recently modernized methods of neutron total scattering that cover a wide Q-range allow the use of appropriate catalytic chemistry that can be measured on time domain to probe directly on site the hydrogenation of benzene within the catalyst pore. Based on this method, it is possible to study the rates of reaction on length scales that can provide measurements equivalent to the size of an atom or a nanometre. Furthermore, the ...

In the pursuit to explaining the creations, mankind has developed theories and beliefs to feed the curious minds. Transcendence is an important concept at understanding the theories and beliefs. For Christian theology creation is found in the Bible specifically in the Genesis. Transcendence in the Bible is the existence of a supreme being who has created all the living and non-living things from nothingness. The Creator is the lord of everything under the sun.

Transcendence in the Bible

In the Christian Bible, transcendence means that God is the most powerful who is above all the creations. God created all the creatures including a ...

The Hiroshima and Nagasaki bombings represent the only incidences that nuclear bombs were ever used in the history of humanity. The devastation, death, and destruction that followed resulted to the surrendering of Japan and thus brought the Second World War to an end. Over the years that followed, the magnitude of the impacts of the nuclear bombs resulted in the debate regarding the justification, or lack thereof regarding the bombing of Japan by the United States. Essentially, the United States had no justification in dropping the bombs in Japan. To a great deal, the justification for the bombing of ...

The documentary film White Light/Black Rain: The Destruction of Hiroshima and Nagasaki was produced and directed by Steven Okazaki in 2007. This film is full of drama, because it shows personal stories of the people that survived the atomic bombings of Hiroshima and Nagasaki. This film is of great importance for understanding the events that took place at the end of the World War II, because it explains the motives of the USA to use the mass destruction weapons and more importantly it shows the devastating consequences of the atomic bombings. Thousands of people were immediately killed, but even ...

The term Cold War has always been used by many to describe the relationship between the Soviet Union and America from 1945 to 1980. The Cold War started as soon as the Second World War ended. It would have been termed World War three by the free society. However, that whimsical name (Cold War) was preferred because there was no military confrontation between the two nations. Many factors led to the emergence of the Cold War, and it had many impacts. The first reason that resulted in the start of the Cold War was the idea of the Soviet ...

The invention of the scanning tunnelling microscope, in 1982 resulted in the emergence of a whole new category of microscopic techniques. All these techniques fall under the family of probe microscopy, which basically involves the interaction of a sample with the sharp tip of a probe at distances of the order of a few μm to a few nm. The atomic force microscope (AFM) is one such scanning probe microscope that builds an image that describes the surface topology of a sample based on the atomic forces of interaction between the tip of the probe and the sample surface. ...

The Treaty for the Prohibition of Nuclear Weapons in Latin America (Treaty of Tlatelolco), which now also includes all states in the Caribbean just turned 40 years since signature in 1967. Its importance as a model for other non-nuclear areas, is constant to peace and international securities contribution, which stood and continue placing today in the center of the political and legal interest. Its parallelism with the Treaty on the Nonproliferation of Nuclear Weapons (NPT) but without Latin American treaty has affected the principle of legal equality of States and has not been an expression of "unequal rights and ...

The heat was intense. The orange light shone on the desert, drying up the remaining puddles of water into vapour, rising into the atmosphere. A lizard crawled slowly, almost dying, parched and with a hide so leather like, one would think it was crisp fried. Slowly, I heard the intense ringing of the siren. Waaang waaaang waaang. It was time to get inside our shelters. The shelters were not made of concrete. Unlike the olden days, concrete was the material of choice. All buildings were once made from stone, from cement mixed with water to form hard solid blocks. ...

After the Second World War of between 1939 and 1945, the globe witnessed the rise of yet another conflict in the form of the Cold War. Apparently, with no need for an alliance against a common foe, the Soviet Union, and the United States turned against each other on the grounds of different ideologies of governance. While Americans were for the democracy based capitalism, the Soviets stood for communism that went against the United States’ perceptions of freedom. To that end, the Cold War did not amount to actual combat between the two powers; although allied countries took to ...
