Sum-frequency generation vibrational spectroscopy (SFG-VS) was first developed in the
1980s and it has been proven a uniquely sensitive and surface/interface selective …

Understanding the role of water in biological processes remains a central challenge in the
life sciences. Water structures in hydration shells of biomolecules are difficult to study in situ …

In this tutorial review, we discuss how the choice of upconversion pulse shape in broadband
vibrational sum-frequency generation (SFG) spectrometer design impacts the chemical or …

The origin of the sum-frequency generation (SFG) signal of the water bending mode has
been controversially debated in the past decade. Unveiling the origin of the signal is …

Aerosol and molecular processing in the atmosphere occurs in a complex and variable
environment consisting of multiple phases and interfacial regions. To explore the effects of …

Many DNA-based technologies involve the immobilization of DNA and therefore require a
fundamental understanding of the DNA structure–function relationship at interfaces. We …

Biomolecular hydration is fundamental to biological functions. Using phase-resolved chiral
sum-frequency generation spectroscopy (SFG), we probe molecular architectures and …

Sub-1 cm–1 high-resolution broadband sum-frequency generation vibrational spectroscopy
(HR-BB-SFG-VS) using synchronized picosecond and femtosecond lasers at 1 kHz was first …

Quartz crystal has been used as intensity and phase reference standard in sum-frequency
generation (SFG) and other nonlinear spectroscopy measurements. In this report, we …

Controlling the semiconductor nanoparticles (NPs) size can alter their optical and electronic
properties, which is an important feature for many optoelectronic device applications. In this …
