Qualitative and quantitative analyte analysis is omnipresent: from quality control in food, pharmaceutical, biotechnology industries, to new molecular syntheses, detection of explosives and drugs, as well as natural compound mixture analysis, such as crude ...
Hydrogels have been used extensively in bioengineering as artificial cell culture supports. Investigation of the interrelationship between cellular response to the hydrogel and its chemistry ideally requires methods that allow characterization without labe ...
Interest in microthrusters has grown significantly in the last two decades for possible applications in small satellites and deep space missions. This thesis is motivated by the need of experimental setup for characterization of microthrusters. In the firs ...
Electrospray microthrusters are a very promising micro-propulsion system which can potentially provide very high specific impulse (Isp ~ 3000s). In this paper, we report on the development of a time-of-flight (ToF) measurement setup for characterization of ...
The coupling of atmospheric pressure ionization (API) sources like electrospray ionization (ESI) to vacuum based applications like mass spectrometry (MS) or ion beam deposition (IBD) is done by differential pumping, starting with a capillary or pinhole inl ...
A method has been presented for accounting for ion fragmentation that occurs within the nonzero field of an ionic electrospray thruster. Given the complexities associated with direct thrust measurements, indirect means (and time-of-flight (TOF) in particul ...

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 ...
A dual-channel electrospray microchip has been developed for electrospray ionization mass spectrometry (ESI-MS) where aqueous samples are mixed at the Taylor cone with an organic buffer. Due to the fast and effective mixing in the Taylor cone, the aqueous ...
Proteomics is nowadays one of the most important research topics in life science for understanding many life activities from the molecular level. The objective is to find out proteins or modifications on proteins that regulate biological events, aging, dis ...
