Researchers at the National Institute of Standards and Technology (NIST) have done a mash-up of two very different experimental techniques—neutron scattering and electrochemical measurements—to enable them to observe structural changes in nanoparticles as they undergo an important type of chemical reaction. Their recently published technique* allows them to directly match up particle size, shape and agglomeration with the “redox” chemical properties of the particles. The measurements are important both for the design of nanoparticles for particular applications and for toxicology studies.

To better understand the fundamental behavior of molecules at surfaces, researchers at the U.S. Department of Energy's Oak Ridge National Laboratory are combining the powers of neutron scattering with chemical analysis.

Neutrons have shown the movement of cholesterol between and within cells takes far longer than previously thought. Findings could impact the treatment of a range of diseases linked to abnormal rates of cholesterol transfer. Scientists using neutron scattering at the ILL and at the NIST Center for Neutron Research have discovered that cholesterol moves far slower within and between cells than previously thought. Their findings reveal how different concentrations of cholesterol within cells are maintained and shed light on severe disorders linked to cholesterol transport abnormalities, including Alzheimer’s, which may help in their treatment.
