We present a simple electron time of flight spectrometer for time resolved photoelectron spectroscopy of liquid samples using a vacuum ultraviolet (VUV) source produced by high-harmonic generation. The field free spectrometer coupled with the time-preservi ...

A microstructured falling film reactor was applied to the dye-sensitized photochemical conversion of 1,5-dihydroxynaphthalene to juglone. This continuous-flow microreactor enables the efficient contacting of a gas and a liquid phase in combination with ext ...

This thesis focuses on the commissioning and characterization of HARMONIUM, an ultrafast tunable EUV source based on high-harmonic generation for performing photoelectron spectroscopy of liquids. In ultrafast photoelectron spectroscopy a short pump pulse i ...

Identification of kinetic models and estimation of reaction and mass-transfer parameters can be performed using the extent-based identification method, whereby each chemical/physical process is handled separately [1-3]. This method is used here to analyze ...

To understand biological processes at the cellular level, a general approach is to alter the cells’ environment and to study their chemical responses. Herein, we present the implementation of an electrochemical push-pull probe, which combines a microfluidi ...

A microchip electrospray emitter with a magnetic bead trap has been designed for solid phase extraction-gradient elution-mass spectrometry (SPE-GEMS). The goal of this method is the detection of analytes at low concentrations and it is here demonstrated us ...

The nanoimmunoassay chip comprises at least flow and control layers, divided into several rows, each row containing a plurality of single assay units, each assay unit contains two spotting chambers (1) and an assay chamber in the middle, wherein neck valve ...

Studies of the real-time dynamics of embryonic development require a gentle embryo handling method, the possibility of long-term live imaging during the complete embryogenesis, as well as of parallelization providing a population's statistics, while keepin ...

The recent years have highlighted the potential of photonic nanostructures to extend the capabilities of optical tweezers and to perform advanced optical manipulations. In this context, two-dimensional photonic crystal cavities have been regarded as promis ...

We present a novel optofluidic differential method for carrying out absorbance spectroscopy of subnanolitre volumes of liquid samples on a microfluidic chip. Due to the reduction of liquid volume, the absorbance detection in microfluidics is often hindered ...

Fundamental biological and biochemical studies, proteomics, practical nutrition-related and medical applications, all the research fields, where bioanalytical chemistry is an essential tool, constantly require the improvement of existing techniques of bioa ...

Micro particle shadow velocimetry (mu PSV) is performed in the present study for simultaneous velocity measurement and interface tracking in both liquid-liquid and gas-liquid two-phase flows through circular microchannels of 5001 mu m diameter. The back-li ...

A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical syste ...

Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based ...
