  • How Does Chemistry Affect The Body

    hair growth all deal with chemistry in their own way. They all have certain chemical reactions and chemical changes that affect the way our bodies work. Even though we study different curriculums during chemistry such as the chemical equations, chemical reactions, and other things we have learned go far beyond what is said in class. During food digestion there are chemical and physical changes occurring. One chemical change for example would be, metabolic rate which is the rate of…

  • 3D Printing: A Case Study

    This essay examines the implications of waste in design and manufacturing with regard to the nature and future sustainability of practices considered modern by contemporary standards. Practices, such as CNC (computer numerically controlled) machining and additive manufacturing such as 3D printing, are the benchmark for modern manufacturing; 'In the domain of manufacturing, computer numerically controlled (CNC) technology is a major contributor to the production capacity of the…

  • The Reflection Of Electron Motion In Atomic Systems

    motion of electrons in the chemical bonds. Controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, the ability to take snapshots of the electron motion dynamics will improve our…

  • Mechanical Vibration Experiment

    The principle of physical governing the measurement system is the Doppler Effect that occurs when the laser beam is reflected from a small area of the testing object that vibrate. The figure below gives the pictorial representation of the Doppler Effect. The loudspeaker represents a sound source and it is assumed that the observer is standing on the right…

  • 3d Printing Research Paper

    transferred to the printer that controls “a nozzle that extrudes heated thermoplastic” to build each layer of on top of each other. Since the object is built on a base, the finished product can be easily removed. The third method is called Selective Laser Sintering (SLS).[6] This method works similarly to SLA, but it uses powered materials instead of liquid resin. All of the current competing methods to CLIP are based on a layer-by-layer approach, which is not only timing consuming, but the…

  • Synthesis Of Ferric Chloride By Sodium Borohydride

    Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

  • 3d Printing Case Study

    apparatus(SLA) machine in 1983, and then 3 years later, in 1986, went on to patent his creation, and co-found 3d Systems with that success. On the other hand, Carl Deckard was working on his own RP(Rapid prototype) machine, which he termed Selective Laser Sintering(SLS). -For what may it be used (needs addressed and/or functions performed)? 3d printing, or…

  • The Importance Of Chemistry In Life

    more focused on the study of the properties of matter as well as the interaction between various types of matter. The interaction is often facilitated by the reactions that involve either electron loss or electron gain, as described by the American Chemical Society (2014). Unlike other sciences, such as physics, chemistry doesn’t put more focus on the nuclear part of the atom, and any other subatomic realm. Perhaps it’s important to emphasize that chemistry is a science, and thus the procedures…

  • Gallium Research Paper

    Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France. Gallium also has origins in the Latin word Gallus.…

  • Chemical Kinetics Lab Report

    CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…
