G3 and G4 Buchwald palladium precatalysts are the newest air, moisture, and thermally stable crossing-coupling complexes used in bond formation for their versatility and high reactivity.
This article reviews the use of block copolymers to coat a surface to make unique nanoscale patterns on a substrate (shown below). Using this method, as opposed to etching with a laser, can improve resolution from the current limit of
Standardize Your Research. We offer both the Universal Proteomics Standard and the Proteomics Dynamic range Standard as complex, well-defined, well characterized reference standards for mass spectrometry.
