Spatial representativeness is an important quality criterion in trace gas monitoring, especially if measurements are intended for regulatory and model validation purposes. Open-path absorption spectroscopy techniques meet the representativeness requirement ...
In this thesis, the use of nanotemplates for steering the molecular self-organization at metallic surfaces is investigated. Nanotemplates are surfaces that exhibit a periodic variation of the adhesion energy on the nanometer scale. Preferential adsorption ...
A spectrometer allowing the measurement of signals with spin-spin relaxation times as short as 0.5 μs has been developed. It consists of a transmitter based on a commercial spectrometer and a homemade receiver. The acquired signals are imported in the soft ...
Using a high-efficiency grating interferometer for hard X rays (10-30 keV) and a phase-stepping technique, separate radiographs of the phase and absorption profiles of bulk samples can be obtained from a single set of measurements. Tomographic reconstructi ...
We present the optical design and realization of a low-resolution liquid-crystal (LC) Fourier-transform spectrometer (FTS). This FTS is based on a polarization interferometer that has a Wollaston prism made of a LC material as a key component. It has a com ...
This thesis further explores the possibilities of scanning near-field optical microscopy (SNOM) in both materials and life sciences. Two experimental SNOM setups were developed: one designed for infrared spectroscopy applications and the other for the imag ...
A new cobalt(II) phosphate compd. has been synthesized using high-temp. flux methods in the CsCl/NaCl media at 650°C. The title compd., Na3CsCo7(PO4)6, forms vibrant purple plate crystals. It crystallizes in a monoclinic space group C2/c (no. 15) with the ...
The goal of our project (HES-SO n°11246) is to develop chemometric methods that enhance the development of chemical reactions. Semi-batch experiments are performed using a fully automated chemical reactor. Real-time analytical data, infrared (IR) spectra f ...
We show that it is possible to immobilize membrane proteins uniformly and reversibly as self-assembled (sub)monolayers on nitrilotriacetic acid-covered sensor surfaces via hexahistidine sequences present either in the protein or in lipid membranes. Fourier ...
The novel versatile Co(I) tris-carbene complex [(TIMENxyl)Co]Cl (1) (TIMEN = (tris[2-(3-aryl-2,3-dihydro-1H-imidazol-2-ylidene)ethyl]amine)) reacts with CO, 1-electron oxidizers such as CH2Cl2, and O2 to yield the Co complexes [(TIMENxyl)Co(CO)]Cl (2), [(T ...
