Description:: Recent advancements in processing and manufacturing techniques have spurred an exponential increase in use of polymer nanocomposites in a variety of applications. A key challenge in using these nanocomposites effectively is the dispersion of nanoparticles in the polymer matrix. Matrix-free assemblies of polymer grafted nanoparticles, called hairy nanoparticles assemblies(aHNPs) have...

Description:: High performance polymers and their composites have wide ranging application in advanced and emerging material systems. The macroscale performance of these advanced materials is often defined by interfaces that induce nanoscale changes in the microstructure or molecular conformations (termed the ‘interphase’) of the polymer. Atomic force microscopy (AFM) is an...

Description:: Transition Metal Dichalcogenides (TDMCs) are one of many families of two-dimensional (2D) beyond graphene, that started to gain more attention due to the need for miniaturization and their unique electrical, mechanical, and optical properties. Some members of TMDCs, such as MoS2, has direct band gap in its monolayer form, making...

Description:: Nanoelectromechanical (NEMS) systems fabricated using atomically-thin materials have low mass and high stiffness and are thus ideal candidates for force and mass sensing applications. Transition metal dichalcogenides (TMDCs) offer certain unique properties in their few-layered form – such as piezoelectricity and a direct band gap in some cases – and...
