Scientists have unraveled details of the mechanism of mechanical reinforcement in glassy polymer nanocomposites.1 Measurements in the interfacial layer ~2–4 nm around nanoparticles revealed that Young’s modulus, which defines the relationship between
Misfit heterojunctions formed by van der Waals (vdW) epitaxial growth of one crystalline metal chalcogenide monolayer on another was demonstrated for the first time to form p-n junctions that exhibit a photovoltaic response.
Scientific Achievement The effects of porous media on precipitation reactions are shown to be important, but poorly understood. Significance and Impact Geochemical reactions within rocks and soils occur in pores.
Recent developments in piezoresponse force microscopy (PFM) and spectroscopy revealed the presence of electromechanical hysteresis loops in a variety of materials including inorganic oxides, polymers and bio systems.
