Polymers

However, there has been an advancement in technology and DNA sequencing has become more reliable and faster by the help of new miniaturized gels that involve the use of conductive polymer materials (eureka). These polymers are organic polymers that are able to conduct electricity. The polymers would replace the platinum electrodes usually used in electrophoresis systems and would be used as part of disposable cassettes/trays containing the agarose gel. Such equipment would avoid the…

as primary or secondary energy source to produce biofuel (Zeller and Grass, 2007). Table 1.1 illustrates the various sources of lignocellulosic biomass from the several sector with some examples. Lignocellulosic materials consist mainly of three polymers which are cellulose, hemicellulose and lignin along with the smaller amounts of pectin, extractives and ash (Collard and Blin, 2014; Bajpai, 2016). The composition of these constituents differ from one plant species to another with age, stage of…

-SiO2@ON/glass was coated with poly(methyl methacrylate) (950 PMMA C4, Micro Chem, 2 mL) by spin coating (500 rpm for 5 s, 1,000 rpm for 5 s, 2,000 rpm for 5 s, 1,000 rpm for 5 s, SP-7200GT spin coater, Intec systems). The plate was cut into 4 pieces of 1.5 × 2.5 cm2 area (Refer to Figure S3), and then added to 5% HF solution (100 mL). In the first 1 min, the glass plate was detached from S-SiO2@ON/glass and removed. The S-SiO2@ON was further etched for 2 h. Caution: HF solution is extremely…

There are some faces we never forget. I can never remember their names but I surely never forget a face. It is like my brain has been programmed to work that way since infancy. It feels has do though it was built into my DNA to remember every face. This particular face that I have remember seeing since my freshman year in college turns out to be my professor in the future. His name, Dr. Mark Pauley. Dr. Mark Pauley is my current Bioinformatics teacher, but that was not the first time I have seen…

polypropylene Electric cables Food packaging Plastic bottles Carpet backing Corrugated boards Structure of Polypropylene Chemical Formula: (C3H6)n Polypropylene is a polymer* with a crystalline structure. - For the crystalline region, many monomer propylene will bond together covalently to form this rigid linear structure. Formation of polymer side chains (crystalline region) (n = controlled chain length of monomers) For the diagram above, the blue lines represent the propylene monomers…

Vertical root fracture is the one of the most critical complications of endodontically treated teeth which can take place before, during or after root canal filling and can end up with tooth loss (1, 2,3). Exaggerated loss of tooth structure due to trauma and caries, dehydration of dentin (4), access cavity preparation, mechanical preparation (5) and irrigation (6) of the root canal, and post space preparation are critical factors that would influence the durability and strength of root canal…

The style of pop art was very different compared to the art styles and techniques of the past. Andy Warhol is known for his artwork, “Campbell’s Soup Cans.” He created this artwork in 1962 (“Pop Art…”). He created this painting with synthetic polymer paint. Warhol’s pop art paintings were famous because they had an uniform structure. The pop art painting, “Drowning Girl,” was painted…

long chains, into polymers, through a process called polymerization. Kevlar has various properties that allow it to be applicable in an array of fields requiring hard, resistant, durable materials, be it canoe racing or aerospace. Amides are chemical compounds in which part of an organic acid replaces one of the hydrogen atoms in ammonia. Polyamides are made by taking an ammonia-like chemical and reacting it with an organic acid. Polyamides like Kevlar, are polymers. Polymers are huge molecules…

would be costly for smaller flock size and can be use by only farmers with at least greater than 10,000 birds. Fourth, it is hard to take out; reusing of the lenses is doubtful and reusing them is the fact that the melting point of the hydrophilic polymer is very close to the sterilization temperature so you could end up with a mass of hydrophilic…

Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue. It was important to keep the amount of glue, borax, and water constant throughout the experiment. In an experiment conducted in class it was hypothesized that the more borax added the denser the slime will be.…
