    Structure). This interaction contributes significantly to the folding and shaping of a protein. Hydrophobic interactions are generally stronger than other weaker forces. Amino acids such as glycine and proline have hydrophobic effect (https://www.chem.wisc.edu/deptfiles/genchem/netorial/modules/biomolecules/modules/protein1/prot13.htm). Van der Waals interaction is…

    they use Velcro which has many problems such as needing both sides to have Velcro in order to stick and loose fibers creating debris in space. The Gecko Gripper would be able to stick to any hard surface regardless of the material and uses Van der Waals force to create tinier material fixing the issue of the loose fibers. Second, we could attach this amazing new technology to robots to travel around the ISS or any other spacecraft to make any repairs required. Currently, astronauts must fix…

    • 3 Pages

    The alcohol Ethanol a chemical compound that is made up of hydrogen, carbon and oxygen and is produced by a fermentation process, this means that this type of alcohol is renewable, although there are non-renewable ways in which to produce this type of alcohol. This alcohol is often mixed into materials such as gasoline, this helps to allow it to be used as a fuel, and help preserve non-renewable materials that could be put to use in more important ways. The mixture of this is often only at a…

    INTRODUCTION Conformational isomerism is a type of stereoisomerism whereby the isomers are interconverted by rotations about the single bonds. There be terms used below such as eclipsed conformation, staggered conformation,dihedral angle and a few more. Eclipsed conformation is the conformation whereby the C-H bonds on one carbon is directly aligned with the C-H bonds of the adjacent carbon. When the C-H bond of one carbon bisects the H-C-H bond on the adjacent carbon, it is known as staggered…

    Adsorption is the bond of particles, particles, or atoms from a gas, fluid, broken down and attached strongly to a surface. This procedure makes a film of the adsorbate on the surface of the adsorbent. This methodology varies from absorbtion, in which a liquid (the absorbate) pervades or is absorbed by a porous solid. Adsorption is a surface-based procedure while absorption includes the entire volume of the material. The term sorption envelops both methodologies, while desorption is the converse…

    Crystalline and Amorphous Solids  Solids can be divided into two classes: crystalline and amorphous. Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures…

    Linus Pauling was awarded the Nobel Prize in chemistry 1954 "for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances"1 however he made significant discoveries in many areas of chemistry including physical and biochemistry. He also made several contributions to both theoretical and applied science from genetic diseases to diagnostic technology.2 Professor G. Hägg, member of the Nobel Committee for Chemistry stated in 1954…

    strong peptide bonds in the primary structure. Some of the factors resulting in the denaturation of proteins are heat and change in pH or potential of hydrogen. An increase in temperature will disrupt the weak forces of attraction between the R groups such as hydrogen bonds, Van der Waales forces and induced dipole-induced dipole attractions. The application of heat on the protein will increase the kinetic energy of the molecules leading to the breakage of the bonds. Thus the stability of the…

    Ramie Fiber Case Study

    • 2076 Words
    • 9 Pages

    3. Results and discussion 3.1. Grafting of CNT on the ramie fabric The schematic representation for the mechanism of ramie fiber surface treatments is shown in Fig. 2. For the alkali treatment of ramie fiber, the NaOH reacts with the hydroxyl groups of the ramie fiber as shown in Fig. 2(a). During silane treatment, the hydrolysis of silane takes place initially (Fig. 2(b)) which then reacts with the active hydroxyl functionalities in ramie fiber (Fig. 2(c)). Each silane molecule has three…
