Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed tremendously, mostly because of their exceptional optoelectronic properties. Core@shell NCs, in which one or more inorganic layers overcoat individual NCs, recently re

Polymer nanofibers, with their specific set of material properties, are favorable for many applications in biomedical engineering (scaffold, stent, or tissue engineering). This application, however, requires the ability to control the manufacturing p

Thermal transport in the axial direction of polymers has been extensively studied, while the strain effect on the thermal conductivity, especially in the radial direction, remains unknown. In this work, we calculated the thermal conductivity in the r

We have investigated the Purcell enhancement of spontaneous Raman scattering in microcavities with a test gas under pressure. Micromirrors were fabricated on bulk substrates and assembled into sealed microcavity arrays into which gases could be intro

Contact resonance atomic force microscope (AFM) methods are used to quantify the elastic and viscoelastic properties of numerous materials including polymers. More recently, U-shaped AFM thermalevers have been developed to allow the local heating of

While the moduli of thin polymer films are known to deviate dramatically from their bulk values, there is not a consensus regarding the nature of this size effect. In particular, indenting experiments appear to contradict results from both buckling e

4A single-walled carbon nanotubes (SWCNs) were fabricated using Si-substituted AlPO4‐5 (SAPO-5) molecular sieves as the template. In comparison with neutral AlPO4‐5, the SAPO-5 framework plays an important role as a catalyst in pyrolyzing the hyd
