When considering concepts in chemistry like colligativeproperties, one might conjure up a mental picture of liquids bubbling insidebeakers in some lab.  In reality,chemistry is involved in all functions of everyday life, even taking placewithin your own body.  Envision kidneydialysis, a procedure prescribed by doctors when a person’s kidney’s fail.  The kidneys, when operating normally, filterout toxins in the bloodstream like potassium and sodium and expel them as urine,and they regulate the body’s electrolyte levels.  Kidney dialysis, more specificallyhemodialysis, artificially removes these toxins from the blood when the kidneysfail.  Once a vein and artery have beenjoined together, blood is pumped out […]

As mankind’s research abilities have increased, so have the discoveries of the universe outside of Earth; outer space. The term outer space corresponds to a lot, but it also just includes our solar system; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, the belts, and everything else. But scientists have begun to look at the finer details, finding out just how exceptional those small pieces are. They could even contain unimaginable stories of physics, exclusive, unique worlds, and even extraterrestrial life. All of those can be descried if you just zoom into Saturn’s Rings and Moons. This paper looks […]

Microwave and millimeter-wave processing of materials, in particular diamonds, is an important research and industrial method that was reviewed by authors44.  CVD techniques, in particular that is based upon microwave-assisted approach, have become one of the most superior methods in the manufacturing of materials, involving different carbon nanoforms, and are well explained in a series of books. The experimental detection give a fundamental perception about the plasma chemistry of hydrocarbon/Ar-rich plasma environment that are used for growing ND films, were discussed. Both main ND types, NCD and UNCD, were obtained via this route45. Between the series of associated works, the […]

Dyeing, a highly complicated and multifaceted chemical process can be described in many different ways, but in short, it is a way of permanently altering the physical colour as perceived by the human of any surface, from cotton or silk fabric to things like glass or wood. There are many processes included in the chemistry of dyeing which describe the interaction of various molecules that bond together and ultimately has the effect of changing colour of an object. In addition to the general dyeing process, the ways in which dyes react to fabrics and other various objects in various environments […]

The article “Knowing what you don’t know can help your grades improve” by Bethany Brookshire is about the Dunning-Kruger effect and how people can improve grades if they know what they don’t know.  At the University of Utah, many students in introductory chemistry were failing, and a chemist named Charles Atwood wanted to change that.  The Dunning-Kruger effect is when someone overestimates how well they can do on a test, even if they don’t actually know enough to pass.  A graduate student of Atwood’s worked with him to promote metacognition or thinking about thinking to the students so they may […]

In  the  sender,  input  bit data  stream  converted into  M  parallel data  stream  after serial-to-parallel  conversion,  so  as  to  realize the  multiple  antennas  output.  For  each path  flow,  we should  first  signal mapping  then  IFFT transform.  IFFT  transform realize  the  OFDM modulation  function  here.  Thefunction  is  that  low-speed of  multi-channel  parallel  data  flow are  modulated  to  mutually orthogonal  K  sub-carrier at  the  same time.  In  order to  reduce  ISI, protect  interval  that  usually use  circle  prefix form  is  joined  in  among symbols  after  IFFT transformation.  At  last, the  data  stream  is  transmitted  after  parallel-to-serial  conversion.1.1. 1 RECEIVING END:In  the  receiver,  each  antenna  received  signals  that  were  sent  by M  transmitting  antennas  and  MIMO  channel  linear  superposition.  The  system  first  desterilizes  and  removes circulation  prefix  from […]

This essay portrays that knowledge indeed comes from the experiences that the individuals go through in the daily activities. Besides, there is an exploration of the phenomenon of qualia in support to the acquisition of knowledge through experience. Importantly, it is relevant to the learning of the critical form of acquisition of knowledge by every individual. In his journal, Jackson presents a character Mary who is only exposed to the black and white television and learns everything she can on neurophysiology but everything like the books she uses, chemistry, and physics in black and white (Jackson 294). Notably, Mary seems […]

The two main ideas that anchor and unify our posters are: the periodic table and the incorporation of chemical compounds in the images. The periodic table idea came from Yasemin who was brainstorming in preparation for the assignment and came across the idea of using the periodic table as a template. She had us all look at the periodic table so we could have an idea of what the layout of the poster could look like. After having a template for the posters and picking a compound to represent each character, Fatima then came up with the idea of having […]

Cereal Chemistry& QualityFinal Exam, FallSemester 2017  1.      Summarize the differentbranches of science that have relevance to dry milling of wheat. Wheat grains have to go through a number of millingprocesses so as to augment product quality and integrity. Dry milling in simpledefinition refers to the separation of the structural parts of the grain as efficientlyas possible so as to realize the desired quality products. Wheat grains initiallyhave to pass through a rigorous meticulous cleaning process which can be up tosix steps of cleaning to get rid of all the unwanted impurities emanating fromthe farmers field such ash debris, sticks and metal […]

People often identify the major of chemical engineering as one of the most difficult anyone can select. Although my personality exemplifies persistence and determination, the daily struggle of managing stacks of lab reports, chemistry problems, and various articles on baffling concepts often make me wonder why I dream to pursue such a profession. I decided that I wanted to study chemical engineering in my junior year of high school. During high school, I knew that I wanted to go into a field that heavily relied on math and science, but I also knew that I didn’t want to study their […]
