Chemistry Essay

Chromatography is a key aspect in chemistry. It allows one to separate molecules based on a variety of things. In labs 3 and 4 we looked at two of the characteristics that molecules carry that can help separate them. Lab 3 used spectrophotometry once again, but the concept that garnered the most interest was ion exchange chromatography. Ion exchange chromatography works by separating molecules based on the individual charges they carry. In our case we used anion exchange chromatography, which…

The longer I spend studying chemistry and biology, the more I find patterns and overlaps between the two disciplines. As I’ve matured in my studies, I have found the boundaries between the sciences to blur, which has led to my desire to do biochemistry. The course encompasses several science disciplines from biophysics and bioengineering to cellular biology and organic chemistry and looks at these from an analytical and quantitative standpoint. The diversity and interdisciplinary nature of…

Dmitri Ivanovich Mendeleyev, born on February 8, 1834, was believed to be the youngest of 14 children. His father, Ivan Pavlovich Mendeleyev was a teacher at a local gymnasium. Around the time Dmitri was born, his father went blind and later died in 1847. Consequently to support the family, his mother Mariya Dmitriyevna Kornileva began working at a small glass factory in a nearby town, and eventually started managing it. On December of 1848, the factory burned down, and the family moved to St.…

Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer chemistry have a wide range of application in day to day life and the research and recent advanced in this field are both industrially and academically notable and increasing day by day . In this review essay I am going to briefly discuss about polymerization. Introduction to polymer chemistry, different types of polymer, the…

Biophysics Ph.D. Program is an exceptional and prestigious program that will provide me the opportunity to broaden my skills and intellect within biochemical research fields. This top-ranked program is an ideal fit for me as it contains the biological chemistry and biophysical that I aspire to focus on during my graduate studies. I am greatly interested in biochemical pathway elucidation and structure-based drug design by understanding the specific molecular interactions of essential enzymes in…

In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…

The overlying questions asked in this experiment were: does the dissolution of metal ions (Ni and Co) from NMC particles into solution change over time as well as to how small particles (glucose) affect this dissolution. From the wet chemistry Figure 3b, it can be seen that the concentration of Co appears to begin and remain between 7 and 10 μM, meaning that the majority of dissolution takes place immediately when the solution is constructed, then increases at a slow rate onwards. This does not…

nuclear breeder reactor in very close detail and his adventures along the way to becoming what he's dreamed of always being, a Scientist. I will be informing you of different chapters in The Radioactive Boy Scout and how they relate to our current chemistry class. Key Idea 1 In chapters one…

In taking advance placement (AP) classes I have learned that determination and a good work ethic will allow you to surpass other people’s expectations of your capability. Determination to succeed has allowed me in AP Chemistry- which is more difficult than I originally anticipated- to maintain an A in the class and learn concepts that deals with my future career. I am expected to learn about matter, chemical bonding, physical properties, rates of chemical reactions, laws of thermodynamics,…
