The addition of nanoparticles (NPs) to a polymer matrix, forming a polymer nanocomposite
(PNC), is known to alter the microscopic dynamic processes of both species which leads to …

Understanding and designing sophisticated new materials require measurements of not
only their average structural properties but also their dynamic behavior. X-ray photon …

Recent advances in optical microscopy instrumentation and processing techniques have led
to imaging that both breaks the diffraction barrier and enables sub-pixel resolution. This …

Scalable manufacturing of high-aspect-ratio multi-material electrodes are important for
advanced energy storage and conversion systems. Such technologies often rely on solution …

Enhanced oil recovery (EOR) techniques have the potential to improve recovery in
unconventional shale oil reservoirs which have prolific short-term success but elusive near …

Using neutron spin-echo spectroscopy, x-ray photon correlation spectroscopy, and bulk
rheology, we studied the effect of particle size on the single-chain dynamics, particle …

We find that the initial, solvent-cast state of nanoparticles (NPs) in a polymer matrix
temporally evolves during thermal annealing such that, at steady state, NPs maximize their …

Surface functionalization of nanoparticles (NPs) plays a crucial role in particle solubility and
reactivity. It is vital for particle nucleation and growth as well as for catalysis. This raises the …

The gelation of PEGylated gold nanoparticles dispersed in a glycerol–water mixture is
probed in situ by x-ray photon correlation spectroscopy. Following the evolution of structure …

The addition of nanoparticles to a polymer matrix can in certain cases induce a reduction in
viscosity, with respect to the pure matrix, in the resulting composites. This counterintuitive …
