Degradation is usually an unwanted process. In certain cases, however, controlled polymer degradation is useful.
WebFood Imitation. One of the most common environmental problems associated with synthetic polymers pollution is that 44 percent of seabird species are known to have ingested synthetic polymers that have been mistaken for food, according to the U.S. National Institutes of Health -- with millions dying from this ingestion every year. WebThe glass transition temperature (Tg) is a phenomenon of amorphous polymers. At this temperature, polymers undergo a transition from glassy to rubbery state. Tg is an important feature of polymer behavior. It marks a region of dramatic changes in the physical and mechanical properties. Below Tg: Due to lack of mobility, the polymers are hard ...
WebPolymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of … WebInhibitory effect of CSOSA/NLC/A-317491 on the Ca 2+ influx of PC12 cells. PC12 cells, highly expressing P2X 3, were used to investigate the effect of CSOSA/NLC/A-317491 on blocking P2X 3 -activated Ca 2+ influx induced by ATP. The intracellular Ca 2+ level was represented by the Fluo-4/AM FI.
A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fun…
