1. Structure evolution of spin-coated phase separated EC/HPC films
Sammanfattning : Porous phase-separated films made of ethylcellulose (EC) and hydroxypropylcellulose (HPC) are commonly used for controlled drug release. The structure of these thin films is controlling the drug transport from the core to the surrounding liquid in the stomach or intestine. However, detailed understanding of the structure evolution is lacking. LÄS MER
2. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence
Sammanfattning : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. LÄS MER
3. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda
Sammanfattning : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. LÄS MER
4. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt
Sammanfattning : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. LÄS MER
5. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature
Sammanfattning : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. LÄS MER
