We herein find that graphene oxide (GO) can enhance the fluorescence signal of conjugated polyelectrolytes (CPEs) with charge transfer characteristics at certain condition, which is due to a relative hydrophobic environment for CPEs induced by GO at low concentration.

Abstract: A two-step process was used to obtain an ultrahigh purity cylindrical tantalum ingot from tantalum powder. Generally, powders cannot be used as raw materials in processes employing electron beam (EB) drip melting. We designed a process that could indeed use powders. The first ...
