immediate amperometric response toward the addition of 0.2 mΜ OA‚ whereas no remarkable effect was observed for the 50-fold excess concentration of possible interferrants such as ethylene glycol (E.G) (CH2OH-CH2OH)‚ glyoxylic acid (GA) (CHO-COOH)‚ dimethyl oxalate (DO) (CH3OOC-COOCH3) and glycolic acid (CH2OH-COOH) (Fig. 8A). However‚ a considerable response was observed after further addition of 0.2 mM OA into the solution containing of interferences. These results show that this sensor has high selectivity

Effects of curing condition of solution cast Nafion® membranes on PEMFC performance Korean J. Chem. Eng.26(3)‚ 679-684 (2009) Thickness of membrane ~ 50µm There are some disadvantages of the solution casting method that the cold cast films are generally mechanically weak‚ susceptible to crack formation and soluble in many polar solvents‚ especially in water at room temperature. Generally‚ the annealed films undergo morphological changes when heated above the glass transition temperature (Tg=109oC

mistake so much of it for food has never been fully explored” (Parker). Some studies say because of the smell of the algae in the ocean. That very well could be true. As algae breaks down naturally in the Ocean they emit a stinky sulfur odor known as dimethyl sulfide. ( National Geographic). Most sea turtles mistake ziplock bags for jellyfish. Bigger fish mistake tiny pieces of debris as plankton. More than two hundred marine animal species have been documented consuming plastic. Seabird’s are one specific

The nervous system is the most important system in the body. It transmits impulses to and from the brain. Disruption of the nerve cells and fibers that transmit the messages severely impairs the body’s ability to carry out complex function. Once a disruption occurs‚ one may never recover and neurological function will steadily degrade. Multiple Sclerosis is a disease that disrupts this network. Multiple Sclerosis (MS) is the most common disabling neurological disease in young adults between 20 and
