Terahertz time-domain spectroscopy has been used for measuring of bovine serum albumin and glucose solutions response. The transmission and the attenuated total internal reflection geometries have been combined for analyzing the dielectric properties of aqueous solutions spectra at 0.07-3.2 THz.

To study the implications of highly space-demanding organic moieties on the properties of self-assembled monolayers (SAMs), triptycyl thiolates and selenolates with and without methylene spacers on Au(111) surfaces were comprehensively studied using ultra-high vacuum infrared reflection absorption spectroscopy, X-ray photoelectron spectroscopy, near-edge X-ray absorption fine structure spectros...

In situ monitoring of DNA hybridization kinetics is achieved via an attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) technique using a sandwich assay structure. The synergistic enhancement effect gives this ATR-SEIRAS-based detection strategy promise to be a convenient and unique platform for bioanalysis.

We use reflection terahertz spectroscopy to locate and produce three-dimensional images of air gaps between stones that resemble fractures, even of subwavelength thicknesses. This technique is found to be promising tool for sculpture and building damage evaluation as well as structural quality control in other dielectric materials.

A universal label-free method for the spectroscopic investigation of polyhistidine-tagged proteins is presented. A solid supported lipid bilayer (SSLB, picture) containing nitrilotriacetic-acid-modified lipids is attached on top of a germanium attenuated total reflection crystal by hydrophilic interactions. Any His tag-modified protein can be immobilized and investigated by FTIR spectroscopy.

Surface sensitivity in the soil X-ray absorption spectroscopy by the fluorescent X-ray yield detection under grazing exit condition is discussed. It is experimentally demonstrated at Si K-edge that the sampling depth can be controlled by changing exit angles in the vicinity of the critical angle for total reflection.

ITO thin films were deposited by spin coating method starting from indium and tin propoxide in the frame of a sol-gel process. Films with the thickness corresponding to 68 nm for one layer deposition were produced and characterized by X-ray diffraction, transmission electron microscopy and infrared reflection spectroscopy. Low conductivity polycrystalline films exhibiting cubical structure (bix...

Ultrafast spectroscopy can provide unique tools to study and control electronic and structural dynamics on a femtosecond time scale. Here we study, the yet little explored multiferroic material, BaTiO3-BiFeO3 (BTO-BFO), that has demonstrated enhanced magnetic properties, a higher DC resistance in comparison to BFO, and improved magnetoelectric coupling. Our studies include ultrafast time resolv...

Analysis by reflection spectrometry was performed to clarify the interfacial adsorption of protonated lipophilic tetraphenylporphyrin derivatives in a dodecane-aqueous sulfuric acid system, and to confirm the utility of partial reflection spectroscopy. Interfacial adsorption was not observed for porphyrins substituted at the 2,6 positions of meso-phenyl groups, suggesting that the substituents ...

Interfacial oxidation and reduction of Prussian Blue (PB), KFe[Fe(CN)6]‚nH2O (n ≈ 10), powder were probed in situ with Fourier transform infrared attenuated total reflection (FT-IR/ATR) spectroscopy. The combination of electrochemistry in the absence of liquid electrolyte with internal reflectance FT-IR spectroscopy was accomplished using a simple two-electrode sandwich-type cell in which a cry...
