1. 1. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Adam Jacobsson Trönndal; [2023]
   Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

3. 2. Lagring av skogsflis med och utan täckning : substansförlusters påverkan av nederbörd och vind

   University essay from SLU/Dept. of Energy and Technology

   Author : Daniel Wetterholm; [2021]
   Keywords : biobränsle; bränslekvalitet; substansförluster; fukthalt; data analys; lagring;

   Abstract : In the supply chain for wood chips, storage is a neccesary part due to seasonal demand. During storage there are several mechanisms occuring, cell respiration, biological degradation and thermo-chemical oxidative reaction. All of the mentioned mechanisms lead to increased temperature, loss of dry matter and energy. READ MORE

4. 3. Microbial test organisms for sterilization processes in food industry

   University essay from Lunds universitet/Bioteknik; Lunds universitet/Teknisk mikrobiologi

   Author : Yasmin Nabila; [2018]
   Keywords : Aseptic processing and packaging; validation; test organisms; Aspergillus brasiliensis; Bacillus atrophaeus; Bacillus subtilis; sterilization; disinfection; applied microbiology; teknisk mikrobiologi; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be designed according to the aseptic condition, including the packaging material, the filling machines, and the surrounding area where the process takes place.

5. 4. Grovfoder till lågdräktiga dikor med speciellt fokus på fiber och protein

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Linn Frendberg; [2017]
   Keywords : Rörflen; ; NDF; ; iNDF; ; torrsiktning; ; partikelstorlek i träck;

   Abstract : Till följd av ökande efterfrågan på betande nötkreatur och nötkött från nötkreatur uppfödda i Sverige har dikalvsproduktionen i Sverige ökat. För att möta behovet behöver produktionen öka ytterligare, vilket kräver en bättre ekonomisk lönsamhet för lantbrukare som håller dikor. READ MORE

6. 5. Improved analytical capacity for determination of forage quality, utilising the gas production technique

   University essay from SLU/Dept. of Agricultural Research for Northern Sweden

   Author : Katarina Niva; [2008]
   Keywords : in vitro; in vivo; in sacco; gas production; gas production technique; incubation time; silage intake;

   Abstract : Voluntary intake and digestibility of forages are characteristics that affect the animal's performance (Mertens, 1994). Today there are several techniques that can be used for studying forage quality and from where the results can be correlated to feed intake and animal performance. READ MORE
