1. 1. Combustibility study of resin for warm magnet coils used at CERN

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Juan Carlos Lopez Santiago; [2023]
   Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. 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. Optical properties of water absorbing textiles for camouflage

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Eveline Örtenberg; [2023]
   Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

   Abstract : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. READ MORE

5. 4. Simulation of Quantum Cascade Lasers

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

   Author : Zakaria Mohamed; [2023]
   Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

   Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

6. 5. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Olina Öhrn; [2023]
   Keywords : ZnO; zinc oxide; cone calorimeter; wood; reaction-to-fire;

   Abstract : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. READ MORE
