Despite the numerous devoted studies, water at solid interfaces remains puzzling. An ongoing debate concerns the nature of interfacial water at a hydrophilic surface, whether it is more solid-like, ice-like, or liquid-like. To answer this question, a complete picture of the distribution of the water molecule structure and molecular interactions has to be… (More)
Virus is known to resonate in the confined-acoustic dipolar mode with microwave of the same frequency. However this effect was not considered in previous virus-microwave interaction studies and microwave-based virus epidemic prevention. Here we show that this structure-resonant energy transfer effect from microwaves to virus can be efficient enough so that… (More)
Interfacial structural and condensed water in nanoporous MCM-41 were investigated by THz-TDS for the first time. A slow reorientation relaxation time of 30 and 100 ps were observed for condensed and structural water.
We demonstrate the magnificent flexibility of the terahertz air-core pipe waveguides. By measuring waveguide attenuation spectra, we found that the pipe waveguides can be easily butt coupled with high coupling efficiency and low bending loss.
