6. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : 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.

7. Phonons in 1-D Graphene Nanoribbons Probed with Raman Spectroscopy : Unraveling Fundamental Properties in 9-atom-wide Graphene Nanoribbons
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This report employs advanced Raman spectroscopy techniques to investigate the fundamental properties of 9-AGNRs comprehensively. It is divided into two main sections addressing distinct aspects of 9-AGNR behavior. In the first section, Polarization Raman spectroscopy (PRS) probes phonon mode symmetries in 9-AGNRs. READ MORE

9. Condition monitoring of a linear rail and carriage system through vibration analysis
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Condition-based maintenance is a highly relevant topic as its implementation can save both components and man-hours. Downtime is often expensive in industrial environments because machines are expensive investments; often, the machines are also part of a larger production line where it is of great importance that no bottlenecks occur.

10. Analysis of Footbridge Comfort Vibrations
University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperAbstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE
