- ItemFiltrace kapalin v medicíně a biotechnologii(Technická Univerzita v Liberci, 2010) Míčová, Hana; Cerman, JiříThis thesis deals with a liquid filtration in medicine and biotechnology. The work was created in cooperation with Elmarco p. l. c. company. For better understanding of this work the basic concepts are characterized first. The basic task was to create a market analysis of the liquid filtration. Two the most interesting applications were chosen after an agreement with Elmarco, these were a filtration during dialysis and a beer filtration. On the basis of the analysis were identified the substitution products and potential customers. The work also contains a characteristic of filter innovation produced from nanofibers. Further a technological - economic evaluation of nanofiber filters was completed and then subsequently were considered opportunities and obstructions of launching in the market.
- ItemFiltrace vzduchu v průmyslu(Technická Univerzita v Liberci, 2010) Laifrová, Lenka; Cerman, JiříThis thesis, deals with the application of nanofiber layers to air filters in cooperation with Elmarco, s.r.o. Task is to analyse market air filtration industry, the current manufacturer of filters and the filters commonly used today. Based on the analysis result segment where the application of nanofiber layers will have highest use possibility is selected. Last task is to prepare a thesis technological-economic evaluation of nanofiber filters for the final application and analyse opportunities and threats in the introduction of innovative products to market.
- ItemPovrchová úprava polymerních materiálů využitím atmosférické trysky(Technická Univerzita v Liberci, 2012) Vaněk, David; Cerman, JiříThe bachelor thesis deals with surface modification of polypropylene using plasma under atmospheric pressure. Plasma was generated by an atmospheric jet, which works with gliding arc discharge (GAD). Many materials have a low surface tension, which either makes impossible their bonding, coloration, printing or makes it more complicated. The purpose of the process is to improve the surface properties of the modified polypropylene, especially to increase its surface tension. Furthermore, this thesis examines the influence of the atmospheric jet height on the sample and the speed of the atmospheric jet shift against the sample.
