A Study of the Effect of a Protein on the Structure of Water in Solution Using Terahertz Time-Domain Spectroscopy

Penkov, Nikita, Valery Yashin, Eugeny Fesenko Jr, Andrew Manokhin, and Eugeny Fesenko.AbstractTerahertz time-domain spectroscopy (THz-TDS) was used to determine the spectra (range = 1.2–120 cm−1) of aqueous solutions of bovine serum albumin (BSA) at pH range 2.5–10....

Excitations and relaxation dynamics in multiferroic GeV 4 S 8 studied by terahertz and dielectric spectroscopy

Reschke, S., Zhe Wang, F. Mayr, E. Ruff, P. Lunkenheimer, V. Tsurkan, and A. Loidl.AbstractWe report on THz time-domain spectroscopy on multiferroic GeV4S8, which undergoes orbital ordering at a Jahn-Teller transition at 30.5 K and exhibits antiferromagnetic order...

A split-ring-resonator-based polarization-insensitive ultra broadband filter in terahertz range

Mei ZhuAbstractSplit-ring-resonators (SRRs) are one of the most common unit cell designs for metamaterials. Though extensively studied and well understood, such devices are often used as narrow-band filters due to SRRs’ sharp resonance to electromagnetic wave....

Structural changes of Bombyx mori fibroin from silk gland to fiber as evidenced by Terahertz spectroscopy and other methods

Wu, Xu, Xiaodong Wu, Min Shao, and Bin Yang.AbstractHere we investigated the structural changes of silk fibroin during Bombyx mori silkworm spinning and reconstitution process. X-ray diffraction, Fourier transform infrared spectroscopy, polarized optical microscopy,...

A phantom study of terahertz spectroscopy and imaging of micro- and nano-diamonds and nano-onions as contrast agents for breast cancer

Bowman, Tyler, Alec Walter, Olga Shenderova, Nicholas Nunn, Gary E. McGuire, and Magda El-Shenawee.AbstractTerahertz (THz) imaging is effective in distinguishing between cancerous, healthy, and fatty tissues in breast tumors, but a challenge remains in the contrast...
