1. Antimicrobials in sewage treatment plants : occurrence, fate and resistance
Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER
2. Pollen och pollenallergen i inomhusmiljön. Metodik för och resultat av laboratorie- och fältmätningar med tonvikt på partikelfilters funktion
Sammanfattning : En stor del av de allergiska besvär som förekommer bland befolkningen i Sverigeorsakas av pollenallergen. Exponering för pollenallergen sker såväl inomhus somutomhus, eftersom uteluft förs in i en byggnad via öppna fönster, ventilationssystemoch eventuella otätheter. LÄS MER
3. Experimental Studies on CO2 Capture Using Absorbent in a Polypropylene Hollow Fiber Membrane Contactor
Sammanfattning : In recent years, membrane gas absorption technology has been considered as one of the promising alternatives to conventional techniques for CO2 capture due to its favorable mass transfer performance. As a hybrid approach of chemical absorption and membrane separation, it exhibits a number of advantages, such as operational flexibility, compact structure, high surface-area-to-volume ratio, linear scale up, modularity and predictable performance.

4. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture
Sammanfattning : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.

5. Applications for Molten Carbonate Fuel Cells
Sammanfattning : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. LÄS MER
