1. 1. Effekten av gödsling med arGrow® granulat på barrplantors tillväxt efter de första två växtsäsongerna

   University essay from SLU/School for Forest Management

   Author : Karl-Anders Wickberg; Mattias Eliasson; [2023]
   Keywords : arginin; plantgödsling; aminosyror;

   Abstract : Tillgången på näringsämnen i marken är mycket stort i förhållande till växternas behov, men ändå är näringstillförseln ofta en tillväxtbegränsande faktor för växterna. De näringsämnen som behövs i störst mängd är kväve, som ofta är hårt bundet i svårlösliga kemiska föreningar. READ MORE

3. 2. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

4. 3. Sublimation temperature prediction of OLED materials : using machine learning

   University essay from Uppsala universitet/Analys och partiella differentialekvationer

   Author : Niklas Norinder; [2023]
   Keywords : Semiconductors; OLED; machine learning; vapor deposition; sublimation; molecular property prediction; regression; ensemble learning; deep learning;

   Abstract : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. READ MORE

5. 4. ELECTRONIC STRUCTURE AND THERMODYNAMIC PROPERTIES OF LI-IONINSERTION IN SULFONAMIDES COMPOUNDS AS ORGANIC HIGH-ENERGY DENSITY CATHODES

   University essay from Uppsala universitet/Materialteori; Uppsala universitet/Kärnfysik

   Author : Mirna Alhanash; [2021]
   Keywords : Organic batteries; computational; DFT; sulfonamides;

   Abstract : The world’s ever-growing energy demand has evoked great interest in exploring renewable energy sources along with sustainable energy storage systems. While inorganic physics of rocking chair mechanism used in Li-ion battery have proven to provide high energy density and high performance, there are problems yet to be overcome in terms of sustainability and recyclability.
