and dissolution. Would you expect crosslinking or crystallinity to have the greater influence? Justify your choice. During swelling and dissolution of polymeric materials‚ the solute molecules diffuse to and occupy positions among the polymer macromolecules. Increasing both the degrees of crosslinking and crystallinity will enhance a polymer’s resistance to these types of degradation since there will be a greater degree of intermolecular bonding between adjacent chains. For linear polymers that are

set-up was a dialyzing set-up was dialyzing bag filled with saturated NaCl immersed in saturated NaCl solution. The set-ups were weighed every five minutes for fifty minutes. The next experiment used gelatin granules and distilled water to test if macromolecules could pass through a semipermeable membrane. The change of weight was observed. The last experiment used dialyzing bag filled with NaCl-methylene blue solution. As the Silver nitrate (AgNO3) was dropped‚ clouds were formed first‚ proving that

Introduction Polymers are large macromolecules composed of many small repeating subunits (monomers) connected via covalent bonds. Both natural and synthetic polymers are created via polymerization of these small molecules (Chemistry 144 Writing Assignment information sheet). The chosen polymer‚ polytetrafluoroethylene (PTFE) in the form of Teflon®‚ is a synthetic fluoropolymer of tetrafluoroethylene (Wikipedia‚ 2015)‚ and is one of the most well-known brand names for PTFE based formulas‚ owned by

1. Are all crimes solvable? No‚ not all crimes are solvable Specialists hunt down confirmation utilizing strategies. Here and there‚ in any case‚ almost no confirmation exists. In this manner‚ not all wrongdoings are resolvable. For instance‚ a burglary carried out by a transient who goes into a house through an open entryway‚ takes nourishment (robbery)‚ eats it‚ and after that leaves the territory inconspicuous is a wrongdoing not liable to be understood. A thievery submitted by a man wearing gloves

I.BASIC CONCEPTS NUCLEIC ACIDS polymeric macromolecules‚ or large biological molecules‚ essential for all known forms of life are made from monomers known as nucleotides Each nucleotide has three components: a 5-carbon sugar‚ a phosphate group‚ and a nitrogenous base If the sugar is deoxyribose‚ the polymer is DNA. If the sugar is ribose‚ the polymer is RNA. Together with proteins‚ nucleic acids are the most important biological macromolecules The two nucleic acids used in repair‚ reproduction
