Rayleigh scattering of nanomaterials can be greatly enhanced by the interface dipole enhancement effect. Consequently real-time true-color imaging of colorful single-walled carbon nanotubes (SWCNTs) on substrates has been successfully achieved under an optical microscope by wide field supercontinuum laser illumination, which facilitates high throughput chirality assignment of individual SWCNTs.

We plot the measured phonon frequencies of the A g1, B2g, and A g2 modes of few-layer black phosphorus (BP) under uniaxial tensile strain along both the near-armchair and near-zigzag directions. The pronounced dependence of the strained phonon frequencies on crystal orientations can be ascribed to an anisotropic mechanical response to uniaxial strain in BP, as a result of its unique puckered crystal structure.

Ultrahigh magnetic gradients at Fe3O4-nanoparticle-modified electrodes (>108 T﹞m-1) induce enhanced mass transport to the electrodes. This is attributed to the magnetic field gradient force and the superparamagnetic properties of nano-Fe3O4, which enable switching of the force using an external magnetic field.

A chemically modified scanning tunneling microscope (STM) tip is fabricated by picking up a Cl ion from the NaCl surface. In comparison with a bare metal tip, the Cl-functionalized tip yields enhanced resolution accompanied by contrast reversal in the STM topograph.
