Selective multi-gas detection is often based on spectroscopic methods in the infrared region. The resulting setup consists of a spectrometer and the probing setup where often the spectrometer makes the sensing device large and heavy and does not allow easy ...
A series of 11 low melting ionic liquids based on meso-substituted A(3)B-porphyrins and A(2)B(2)-porphyrins containing one or two pyridyl substituents have been synthesized in high yields. Three of them are liquids at room temperature. All these porphyrini ...
We report on the first successful high-resolution spectroscopic studies on isolated para-coumaric acid, the chromophore of the photoactive yellow protein which has become a model system for studying biological light induced signal transduction. Employing v ...

There has been a very strong development of the sensors based on surface plasmon resonance during the last thirty years, mostly for biological and biomedical applications. If the first experiments in this field were carried out at the beginning of the 20t ...

Combined with high and ultra high pressure liquid chromatography, mass spectrometry-based peptide and protein structure analysis requires high resolution and mass accuracy achievable within short ion detection time. Although Fourier transform ion cyclotron ...
This is the second part of two articles reporting investigation on a thermal-detector-type far-infrared sensor operating in the 8–14 µm wavelength region using Low-Pressure Chemical Vapor Deposition (LPCVD) deposited low-stress Si-rich nitride (SiN) membra ...
This is the first part of the two articles reporting investigation of a thermal detector-type far-infrared sensor operating in the 8–14µm wavelength, using Low-Pressure-Chemical-Vapor-Deposition (LPCVD)- deposited low-stress Si-rich nitride (SiN)membrane a ...

The [Re-I(CO)(3)(4,7-dimethyl-1,10-phenanthroline)(histidine-124)(tryptophan-122)] complex, denoted [Re-I(dmp)(W122)], of Pseudomonas aeruginosa azurin behaves as a single photoactive unit that triggers very fast electron transfer (ET) from a distant (2 nm ...
In this thesis report, we describe a novel home-built instrument designed to study the spectroscopy of biomolecular ions in the gas phase and at low temperature, and we present the first experimental results obtained on protonated aromatic amino acids. The ...
The mid-infrared range is of interest in spectroscopic applications, due to the large number of organic compounds that exhibit characteristic absorption bands in this spectral region. Semiconductor technology, however, has been developed mainly for the nea ...
