Extracellular proteins devoid of signal peptides use nonclassical secretion mechanisms for
their export. These mechanisms are independent of the endoplasmic reticulum and Golgi …

Nanoparticles are produced in natural phenomena or synthesized artificially for
technological applications. Their frequent contact with humans has been judged potentially …

Using density functional theory, we calculate the IR and Raman signatures of the thiophenol
(TP) molecule adsorbed on gold clusters by mimicking the different types of adsorption sites …

Nonlinear optical Sum and Difference-Frequency spectroscopies are used to probe and
model the surface of thiophenol-functionalised gold nanoparticles grafted on a Si (100) …

Nano-optics explores linear and nonlinear phenomena at the nanoscale to advance
fundamental knowledge about materials and their interaction with light in the classical and …

This work describes an electrochemical study of 4-nitrobenzene diazonium (4-NBD)
reduction onto glassy carbon (GC) electrode coupled to in situ sum-frequency generation …

In this work, we demonstrated for the first time that the nonlinear optical (NLO) response of
interfacial water, as obtained from sum frequency generation (SFG) spectroscopy, can be …

Here, we demonstrate how sum frequency generation (SFG), a vibrational spectroscopy
based on a nonlinear three‐photon mixing process, may provide a direct and unique …

The vibrational nonlinear activity of films of 2, 4‐dinitrophenyl phospholipid (DNP) at the
solid interface is measured by sum‐frequency generation spectroscopy (SFG). Hybrid …

Publisher Summary This chapter discusses different aspects of infrared-visible sum-
frequency generation (SFG) spectroscopy. It emphasizes that this noninvasive optical probe …
