Application

Binding agent for printing inks and foil, hardboard and ceramic lacquers.
Poly(butyl methacrylate-co-methyl methacrylate) (P(BMA-co-MMA) ) may be used to synthesize porous interpenetrating polymer network (IPN) with low-density polymers. These IPN structures are applicable as membranes for separation of liquid mixtures due to their high mechanical strength and selectivity. P(BMA-co-MMA) particles may be used to encapsulate single non-aggregated semiconducting quantum dots (QDs) for size enlargement.These hybrid organic/inorganic nanostructures may be used as single photon sources.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold.

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