  • Dcpip Synthesis

    The process of photosynthesis is composed of two phases: light-dependent reactions and the Calvin cycle. The first stage (light-dependent reactions) occurs in the thylakoid membrane, which absorbs light energy to create NADPH and a proton gradient used to power the synthesis of ATP. The latter occurs in the stroma, and results in carbon dioxide fixation. In this experiment, only the light-dependent reactions were studied. 2,6-dichlorophenol-indophenol (DCPIP) was used as an artificial…

  • Gabriel Amine Vs Pyrrole Lab Report

    highly electronegative oxygen and nitrogen atoms. The combined electron-withdrawing resonance and inductive effect ensures that the negative charge on the nitrogen atom is effectively dispersed. Step 2: nucleophilic substitution In Section 3.6 Halogen Derivatives, it was mentioned that an alkyl halide can undergo nucleophilic substitution by heating with excess alcoholic ammonia to yield a primary amine. Excess ammonia is necessary if a high yield of the primary amine is required. If excess…

  • Interpretation Of The Noesy: Nuclear Overhauser Effect

    Interpretation of the NOESY: (Nuclear Overhauser Effect) spectrum of 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a) is as follows. Strong coupling interaction of protons of 2nd and 4th position in 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a), was not so strongly observed in COSY because it involves long range coupling i.e. protons attached between 2nd and 4th carbon atom. Hence, we studied NOESY to know the spacial interaction between these two protons. Thus, the…

  • Raadiant Energy: Kinetic Energy

    Energy can be potential or kinetic. Radiant energy is a form of Kinetic energy. Movement of atoms, molecules, objects, waves, substances referring to a Kinetic energy. There are many different forms of kinetic energies like sound, motion, thermal energy, electrical energy. Nevertheless, there would be no life on Earth without radiant energy. What is radiant energy? The energy of electromagnetic waves and gravitational radiation is radiant energy. Radiant energy is the result of a change in…

  • Temazepam Research Paper

    Temazepam, commonly known as Restoril, is a sleeping pill that is prescribed to patients. This drug is classified under a type of drugs called benozaphines, which are, “a large group of drugs with sedative and anxiety-reducing properties, which have been found valuable for a large number of uses” (UXL Encyclopedia of Drugs and Addictive Substances). This class of drugs is used to reduce anxiety and help with insomnia. Since temazepam is classified as a benzodiazepine, I was curious as to what…

  • Interview On Toys

    For the interview , I asked a Quincey -playing in the building area, building with blocks, what is favorite toy was, and he grabbed some building blocks, and stacked them ,and replied ” Blocks are my favorite toys , especially the green ones.” I asked him “why” , and he responded that - “you can build towers.” He said “you can build a red tower, a blue one, a green one, and lastly a yellow one.” Quincey stated he also enjoyed counting them. He is fully engaged in building, and can build small…

  • Tin Dioxide Essay

    CHAPTER 1 TIN OXIDE 1.1 Introduction Tin dioxide, also known by the systematic name tin(IV) oxide and stannic oxide in the older notation, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six…

  • The Three Different Methods Of Heat Transfer

    Most people know that heat moves from hot objects to cold objects, but do they know how that heat is transferred? There are only three ways that heat can be transferred: conduction, convection, and radiation. Today I will endeavor to inform the reader on how these three different methods of heat transfer work and provide examples of where they occur in the real world. The most prevalent, and most commonly recognized, form of heat transfer is conduction. Conduction is the transfer of heat…

  • Spectroscopy Essay

    Types of Spectroscopy used in Organic Chemistry 1.1 Introduction Spectroscopy is the study of the interaction between matter and light (electromagnetic radiation) (Crouch & Skoog, 2007). It is often phrased as the light of knowledge (Reusch, 2013). In the past, spectroscopy started by the study of visible light dispersed according to its wavelength by a prism (Anon., n.d.). Now, with the knowledge of light having both wave-like and particle-like characteristics, with given frequency or…

  • Membranes

    polar bonding.127 Therefore, the polymer surfaces suitable to this kind of modification must have sites that are able to undergo electrophilic or nucleophilic attack. Such polymer structures include benzene rings, hydroxyl groups, double bonds or halogens.127 The polymer surfaces can be functionalised via nitration,135 amination,135 bromination,136 sulfonation,122,137,138 benzoylation,139 and carboxylation.138 The modification of polyphenylene oxide (PPO) as an example is discussed. The…
