1. 1. Techno-economic fesibility of a hybrid CSP (sCO2) - PV plant for hydrogen production

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Patricia Perez De La Calle; [2023]
   Keywords : Soec oxide electrolyzer cell SOEC ; Concentrated solar plant CSP ; Super critical cO2 sCO2 ; photovoltaic field PV ; Thermal storage TES ; electrolyzer; MoSES; high temperature electrolysis THE .;

   Abstract : The global need to eliminate CO2 emissions and its consequent reduction in the use of fossil fuels drives the ongoing energy transition that highly involves the research achievements of the scientific community to reach the goals of this purpose. Renewable sources like photovoltaic and wind energy, are central to this endeavor, however, the intermittency of natural resources makes it non-dispatchable and energy storage is fundamental.

3. 2. Comparing different methods of measuring particle size for pharmaceutical excipients

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Jiawen Wang; [2022]
   Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

   Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

4. 3. Size detection limits of spICP-MS for analysis of nanoparticles in environmental media

   University essay from SLU/Dept. of Soil and Environment

   Author : Eline Goossens; [2018]
   Keywords : nanoparticle; detection limit; single particle ICP-MS; environmental analysis;

   Abstract : Nanoparticles (NP) are widely integrated in our everyday lives, such as consumer products, health, agriculture, food, etc. This has resulted in a growing concern for their possible harmful effect on human health and the environment and the demand for characterization. READ MORE

5. 4. Measuring volatile nicotine from electronic cigarettes

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Simon Lundegard; [2017]
   Keywords : AMS; denuder; e-juice; electronic cigarettes; NGI; nicotine; SMPS; Technology and Engineering; Chemistry;

   Abstract : This thesis is focused on electronic cigarettes and the formulations (also known as e-juices) associated with these. The reason is that there have been countless studies on the health effects and nicotine delivery of normal cigarettes, but not as much on electronic cigarettes. READ MORE

6. 5. Development of a method to measure “soft particles” in the fuel

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Botond Csontos; [2016]
   Keywords : Biodiesel; Particle sizing; Particles; Filter blocking; Nozzle hole fouling.;

   Abstract : As environmental awareness raises the expectations to reduce emission of modern diesel engines are growing as well. Fuel diversity and the advanced injector systems requires even more attention on an ever existing problem which is called nozzle hole fouling. READ MORE
