General description

Poly(acrylic acid) solution (PAA) is an anionic polymer that can be synthesized by the free radical polymerization of acrylic acid. It has a swelling nature that tends to absorb and retain the water. It has a high ion exchange capacity that makes it useful in the development of membranes.

Application

PAA can be used for a variety of applications such as:
  • a surfactant in the formation of photonic crystals
  • a binder for the development of Silicon anode based lithium ion batteries
  • polyelectrolyte membranes for electronics and optoelectronics based applications

Magnetic-plasmonic nanoparticles offer the combined benefits of both a magnetic probe as well as additional imaging modes usually associated with noble metal nanoparticles. Professor Shinya Maenosono (Japan Advanced Institute of Science and Technology) explores the synthesis, characterization, and proof-of-concept application of Ag/FeCo/Ag core/shell/shell magnetic-plasmonic nanobeads for imaging and isolation of cellular organelles (autophagosomes of COS-1 cells).

We have discussed shortly the applications of 1:1 and 2:1 phyllosilicate material in membrane technology, as well as the basic geometric understanding of their layered structures.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
