Marie Sklodowska Curie was a Polish chemist who was born on November 7, 1867, in Warsaw. Exceeding all expectations, Curie excelled in and outside of the classroom by achieving a masters degree in physics and math. Curie was also the only woman of her time to win the Nobel Peace Prize twice in chemistry and in physics. Having one of the world’s most brilliant minds, Marie Curie discovered the field of atomic physics, polonium, leading to the development of the atom bomb, and radium, which paved…

is the energy released during nuclear fission or fusion. Nuclear fission is a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. Nuclear fusion on the contrary is the exact opposite; it gathers energy from the heavy nucleus combining with the shot particle. These two combined produce a lot of energy that is used all over the world on a daily basis. Nuclear power has proved to serve a huge part of our society today. For…

read at night, or bright to the point where they would be seen. Undark Paint, created by William J. Hammer in 1902, provided a perfect solution. Radiation energy found in luminescent particles in the alpha radiation emitted by radium is…

Moles 1.How is molar mass calculated and why is it useful? Molar mass is calculated by going to the periodic table finding each mass of each element in the compound then adding them all up based on how many of those elements are in the compound. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. Mole is considered the unit for amount in chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the…

Victor Ninov is a former high energy physicist at Lawrence Berkley National Laboratory (LBNL) who specialized in synthesizing heavy elements. Ninov has participated in the discovery of element 110 darmstadtium, element 111 roentgenium and element 112 copernicium. Ninov is famous for designing a computer software that detects the decay chain of chemical elements with an atomic number greater than 92. Ninov was the only one in the group capable of using the computer software and then he would…

will aggregate, leading to inclusions within the cell bodies and its intracellular processes [6]. Furthermore, Lewy pathology (LP) can be found in the peripheral nervous system and spinal cord in PD [7]. Alpha-synuclein becomes present…

Salbutamol Discovery Chiral chemistry was introduced in 1848 by French chemist and biologist, Louis Pasteur. He discovered this new branch of chemistry after he separated two isomers of ammonium tartate (1). This paved the way for several progressions in the pharmaceutical industry. Although it took approximately a century for scientists to use chiral compounds as effective drugs, they have played a remarkable role in the life of plants and animals (1). The credit for discovering the chiral…

Radiotherapy Radiation has many beneficial ways to be used. The type that will be discussed in this report is its medical uses in treating cancer. The treatment is called radiation therapy or radiotherapy (National Cancer Institute 2010). More than half of all cancer patients get radiotherapy as part of their treatment (American Cancer Society 2014). It is often used alongside chemotherapy (D Hermann n.d.). The purpose of radiation therapy is to cure or control the cancer or to relieve symptoms…

RESEARCH TASK AND WRITTEN REPORT Many theoretical and experimental problems were not solved in the early twentieth century. There were attempts to explain the behaviour of matter on the atomic level with the laws of classical physics however they were not accurate nor successful. It was not until the period between 1900 and 1930 where a revolution occurred and a generalised formulation called quantum mechanic was developed. And since the understanding of the structure of the nucleus of the atoms…

Nanoparticles (NPs) have piqued the interest of scientists because of their distinct physical, chemical and biological properties when compared to bulk material. These differences in characteristics can be attributed to the high surface-to-volume ratio (SA:V) of NPs compared to bulk material. Since NPs have a higher SA:V than bulk material, they are more reactive than their bulk counterparts; therefore, the surface characteristics of NPs can be easily manipulated. (Xuefei et al, 2014) Metal NPs…
