This review introduces the THz spectral imaging technique for moisture detection, the Debye relaxation model, and other related theories, reviews the research progress of the terahertz …

THz water, derived from natural minerals, escalates solvation and biological activity via resonating water molecules. Its bactericidal version exploits alkalinity and electrical properties to dissolve …

2024年4月24日 · In this study, we optically measured water-filled rectangular loop nanogaps with gap widths of 2 to 20 nm to determine refractive indices of nanoconfined water at terahertz …

采用分子动力学模拟方法, 本文研究了不同水模型在常温常压下的太赫兹吸收谱, 并且进一步基于温度研究了水的太赫兹吸收谱对氢键网络强弱的依赖性, 发现温度的升高会使氢键网络的太赫兹 …

Here we performed open aperture z-scan transmission experiments on static liquid cells, and detect the THz fields with electro-optical techniques. We show that it is possible to quantify the …

2023年6月30日 · The frequency range of terahertz waves (THz waves) is between 0.1 and 10 THz and they have properties such as low energy, penetration, transients, and spectral …

We explore the potential of liquid water as efficient scheme of table-top THz generator and detector. Further underlying physical mechanism, such as the ultrafast electron migration and …

Here, we use Z-scan technology to directly measure the nonlinear absorption coefficient and nonlinear refractive index of liquid water excited at a higher THz range of 0.1–3 THz. …

The terahertz (THz) Kerr effect technique, as a novel tool, is expected to be useful in exploring the low-frequency molecular dynamics of liquid water. Here, we use an intense and...
