Carbon Nanotubes Research Paper

Chemistry is in everyday life, including space travel. One might ask what is involved with space travel? A lot of times fuel for the rockets come to mind, but there is also the making of the rocket itself and how they breathe all the way up into space. A method they use for breathing in space is electrolysis. Other factors are the diet, the removal of waste, and the impact of space. In spacecraft fuel the two main categories are liquid and solid rockets, which have different combinations and impulse values. In the development of a spacecraft carbon nanotubes are expected to used.
Rocket propulsion, of course, includes combustion. Combustion is where a substance reacts with oxygen and gives off heat. The source of oxygen is called an oxidizer

Carbon nanotubes are an allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology, electronics, optics and other fields of materials science. Properties of carbon nanotubes include high electrical conductivity, very high tensile strength, very flexible; can be bent considerably without damage, very elastic, high thermal conductivity, and low thermal expansion coefficient. Other properties include good electron field emitters and aspect ratio. Electrical conductivity in the nanotubes could be useful in future spacecraft; the body itself could store power and have several functions and bend themselves. That is where the flexibility comes in. The thermal conductivity could be used as an insulator for the extreme temperatures in …show more content…
Plants on earth grow in soil and the roots grow down to absorb nutrients and water. Instead of the roots going in one direction, in space they go in all directions and since there is no gravity everything floats. A “veggie” is a capsule which includes a plant pillow to keep the soil, water, and the plant itself from floating around. The roots can be drawn down by sticking seedlings onto a wicking material that is included in the plant pillow. Sunlight is not available however, it can be replaced by LEDs to give the plants energy. LEDs (light emitting diodes) produce light when it conducts an electric current. The following plants are examples that have been grown in space: Arabidopsis (Thale Cress), Mizuna lettuce, Super dwarf wheat, Apogey wheat, Bassica rapa (Oilseed), Rice, Tulips, Kalanchoe (tropical flowered plant), flax, peas, radishes, garlic, cucumbers, parsley, and dill.
Everyone has to use the bathroom, even in space. So how do astronauts get rid of their waste? Without gravity, it would be very challenging to try and use the restroom. The astronauts could float around and so could the waste itself. To hold down the astronauts, they are strapped by their feet and thighs. For the waste flushing toilets are used that contain air instead of water. The waste is pulled away from the body by the airflow of the toilets. The liquid waste is disposed outside and the liquid is evaporated by the severe temperatures and pressure in

    In this study, the effects of both varying temperatures and light intensity upon the photosynthetic rate of spinach leaves were observed. Using the ‘spinach immersion’ technique, the rate of photosynthesis under various conditions was quantified by observing the amount of spinach floating on top of a sodium bicarbonate solution. The sodium bicarbonate solution simultaneously supplied the spinach with carbon dioxide for use in photosynthesis, and caused it to sink. When the leaf underwent photosynthesis and produced oxygen gas, the leaf floated to the surface. It was hypothesized that an increase of either temperature or light intensity would lead to an increased rate of photosynthesis, to a degree.…

    Because of their structure they have no Vander Waal’s forces and have the highest strength of any material. According to Miodownik, if an elevator connecting the earth and space was to be built, it would be made from carbon nanotubes. Extravagant ideas like this are only possible because of the advances in materials science. Currently there isn’t a material, maybe with the exception of the carbon nanotubes, that is strong enough to support its own weight when built to a height of many miles. But possibly with the further advancement of materials science such a structure will be possible.…

    Have you ever experienced a concussion? As we all know to go back onto the field or back onto the court the injured athlete must be cleared by a doctor or medical physician. Even though a full checkup and correct healing process is needed, many athletes go back way earlier and without clearance from the doctor. Statistics show that there are nearly 300,000 sports-related concussions that occur each year in the United States. That is more than 5% of high school athletes receive concussion each year while participating in impacting sports.…

    “Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total there are five (5) chemical reactions.…

    Chemistry is an umbrella term that refers to any study of properties, compositions, and reactions occurring between elements at an atomic level. Chemistry exists in many forms: biochemistry, theoretical chemistry, and nanochemistry for instance. One form of chemistry, nuclear chemistry, deals with radioactivity and nuclear processes. The most notable of these processes is transmutation. Transmutation refers to the action that changes an atom of a specific element to a different element, either naturally or artificially.…

    1. I believe we were asked to find the paper using the citation provided rather than having a copy of the paper posted on the D2L website in order to familiarize ourselves with how to interpret citations, since it is critical to understand what information (for example: title, author, publishing date) is provided within the citation, and also to get a sense of how the Ryerson online library site operates, along with the various resources offered on the library site. 2. The legal reason as to why the paper was not posted on Brightspace, but instead we were asked to go through the Ryerson library site in order to access the paper, may be due to the fact that the authors’ permission must be obtained prior to posting the scientific paper to Brightspace.…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    Chemistry is a branch of science that deals with the identification of the substances of which matter is composed. It also involves the properties and the ways in which they interact, combine, and change. Chemistry is important to life. The environment is composed of many chemicals without identification of chemicals we wouldn’t know what chemicals are safe to have around or which chemicals are harmful and dangerous to our bodies. To answer the enduring question, how do we gain knowledge to understand a chemical system, particularly since we cannot see atoms or molecules?…
