  1. 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 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.

  3. 7. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yujie Fu; [2023]
    Keywords : Inkjet printing; piezoelectric energy harvester; diphenylalanine peptide; self-assembly; Bläckstråleutskrift; piezoelektrisk energiskördare; difenylalaninpeptid; självmontering;

    Abstract : Diphenylalanine peptide (Phe-Phe or FF) is a very promising bio-material in the future wearable electronics application due to its self-assembly into nanotubes and nanoribbons with high shear piezoelectric coefficient which is comparable to traditional inorganic piezoelectric materials. In order to efficiently harvest piezoelectric response, alignment and unidirectional polarization of FF nanotubes are required. READ MORE

  4. 8. Manufacturing batteries of the future : Critical challenges and undertakings to create the next generation energy storage

    University essay from KTH/Produktionsutveckling

    Author : Victor Carlsson; Victor Granat; [2023]
    Keywords : ;

    Abstract : In today's world, a dominating piece of news is the global race for large-scale production of Lithium-ion batteries (LIB). LIBs are important because they have become the most widely used type of rechargeable battery in modern electronic devices, such as smartphones, laptops, energy storage systems, and electric vehicles.

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Tejbo; [2023]
    Keywords : catalyst; metal-oxide; electrolysis;

    Abstract : Finding materials based on non-rare earth metals is vital for the global transition to a more sustainable economy. Discovering useful properties in common metal oxides is a promising avenue for new materials. READ MORE

  6. 10. Metacaspase type II : Biochemical studies of the activation anddegradation process of calcium-independentmetacaspase type II from Arabidopsis thaliana

    University essay from Uppsala universitet/Nationellt resurscentrum för biologi och bioteknik

    Author : Anna Vikhagen; [2023]
    Keywords : ;

    Abstract : Proteases are found in all living kingdoms and are absolute essential for a functional cell to beable to break down peptide bonds. Metacaspases are proteases with the ability to cleave afterarginine and lysine residues. READ MORE
