1. 1. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Md Shabbir Hossain Khan; [2022]
   Keywords : Scattering; Absorption; Nanoparticle; Cross-section; Mie; Electromagnetic; FDTD; dipole; Wavenumber.;

   Abstract : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. READ MORE

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. Atmospheric Attenuation for Lidar Systems in Adverse Weather Conditions

   University essay from Umeå universitet/Institutionen för fysik

   Author : Johan Viklund; [2021]
   Keywords : Lidar; Lidar equation; Extinction coefficient; Signal attenuation;

   Abstract : In this study, the weather impact on lidar signals has been researched. A lidar system was placed with a target at approximately 90 m and has together with a weather station collected data for about a year before this study. READ MORE

5. 4. Economic Development and CO2 emissons : A comparison of High- and Middle-income economies

   University essay from Jönköping University/Internationella Handelshögskolan

   Author : Robin Abrahamsson; Rasmus Augustsson; [2020]
   Keywords : Revised kuznets curve; Environmental Kuznets curve; CO2 emissions; Middle-income; High-income; Economic Development;

   Abstract : The purpose of this paper is to investigate the relationship between economic development and pollution in the middle- and high-income countries for the period between 1960 and 2014. The study is conducted by first testing the environmental Kuznets curve, an economic theory that income has an inverted U-shape relationship with environmental degradation. READ MORE

6. 5. Correcting biological infrared spectroscopy data for atmospheric gases and Mie scattering

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Author : Stéphan Pissot; [2020]
   Keywords : FTIR; spectroscopy; chemometrics; infrared absorption microscopy; atmospheric correction; scattering correction; Physics and Astronomy;

   Abstract : Infrared absorption microscopy is a powerful chemometric tool with a wide variety of applications. It is, however, subject to considerable disturbances from atmospheric gases and scattering effects. READ MORE
