Labio, a.s. – studie možností rozšíření plynového chromatografu
Divoký, Martin
2015 - Czech
Projekt byl zaměřen na testování a vývoj UV plynového chromatografu Labio G11. Spektrometr chromatografu byl modifikován, aby došlo k rychlejšímu propláchnutí vnitřního prostoru dusíkem (neabsorbuje v UV) a byla uspíšena připravenost k provozu. Dále byla otestována citlivost spektrometru v UV pod 150 nm a navrženy možnosti rozšíření citlivosti v této oblasti. This project aimed at testing and development of a UV gas chromatograph Labio G11. A spectrometer from the chromatograph was modified in order to increase nitrogen gas flow in the device and speed at which the inner of the spectrometer is filled with nitrogen (that doesn’t absorb in UV). This allowed decreasing startup time of the spectrometer. Additionally, sensitivity of the spectrometer in region below 150 nm was tested and ways to increase this sensitivity were proposed.

Fabrication methods of diamond coated Love wave SAW biosensors for bacterial detection applications
Drbohlavová, L.; Bulíř, J.; Valeš, Václav; Jákl Křečmarová, M.; Taylor, Andrew; Talbi, A.; Soltani, A.; Mortet, Vincent
2015 - English
Pathogen detection has a huge importance in the food industry and it can play significant role in the medical practice. This paper focus on the fabrication methods of diamond coated Love wave surface acoustic wave (LW-SAW) biosensors for bacteria detection. LW-SAW sensors have been fabricated on AT-quartz crystals. Interdigitated transducers have been patterned by RF sputtering and photolithography techniques. Amorphous silicon oxide (SiO2) guiding layer and nano-crystalline diamond layer were both deposited by plasma enhanced chemical vapor deposition at low temperature. Preliminary experimental study of diamond surface termination for sensors bio-functionalization is also reported.

Doped DLC coatings for biomedical applications
Písařík, Petr
2015 - English
Nowadays there are materials having excellent properties for use in medicine (Diamond-like carbon, Hydroxyapatite, …). Diamond-like carbon (DLC) is a metastable form of amorphous carbon containing bonded carbon atoms of sp2 and sp3 hybridized orbital. DLC layers are semiconductors with high mechanical hardness, chemical inertness, low coefficient of friction, high thermal conductivity, good electrical and optical properties, biocompatibility and no cytotoxicity. All properties of the films are not always ideal, so it is necessary to modify the layer. One example of how to modify the properties of thin layers are dopations. The incorporation of dopants in films may lead to greater multifunctionality and much improved properties. Most modifications were made to modify contact angle and surface energy, to reduce internal stresses, to decrease surface roughness, coefficient of friction or wear....

Hydrogen-terminated diamond surface as gas sensing layer working at room temperature
Davydova, Marina; Kulha, P.; Babchenko, Oleg; Kromka, Alexander
2015 - English
Effect of fluorine- and hydrogen-terminated diamond surface on the gas sensing properties at room temperature was investigated. The gas sensing properties diamond-based sensor were measured by the changes of electrical resistance to various volatile organic compounds (C6H6, C3H6O, isopropylalcohol) and relative humidity. The comparative sensing performance of hydrogenated diamond surface shows improvement in sensitivity toward benzene, acetone, isopropylalcohol and humid air in contrast to fluorinated diamond surface, where the surface conductivity was suppressed.
