probe spectroscopy. Such a high resolution cannot be simply explained using the commonly …

By taking advantage of the tensor nature of surface-enhanced Raman scattering (SERS), we
track trajectories of the linker molecule and a CO molecule chemisorbed at the hot spot of a …

Calculated using classical electromagnetism, the van der Waals force increases without limit
as two surfaces approach. In reality, the force saturates because the electrons cannot …

In this work, an electrochemical sensor for the simultaneous detection of sunset yellow (SY)
and tartrazine (Tz) food dyes is developed. It is based on carbon nanofibers (CNF) …
