For close to two decades, Cornell scientists have developed processes for using polymers to self-assemble inorganic nanoparticles into porous structures that could revolutionize electronics, energy and more. This process has now been driven to an unprecedented level of precision using metal nanoparticles, and is supported by rigorous analysis of the theoretical details behind why and how these particles assemble with polymers.
New research indicates that nanoparticles are able to change their binding at surfaces to proteins abundant in the blood depending on whether the protein is bound to fat molecules at the time. The findings indicate how nanoparticles interact with blood proteins in the body by influencing the efficiency of the nanoparticle transport to surfaces.
Researchers investigated the topological insulator bismuth selenide by spin-resolved photoelectron spectroscopy. They found an astonishing difference depending on whether it is illuminated by circularly polarized light in the vacuum ultraviolet and in the ultraviolet spectral range. This result could help explaining how spin currents can be generated in topological insulators.
