2. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields
University essay from Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysikAbstract : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. READ MORE

3. Film formation of mixed-halide perovskites for PSCs
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. READ MORE

4. The use of graphene quantum dots as detection elements in nanomaterials-based sensors for forensic applications
University essay from KTH/Tillämpad fysikAbstract : The large-scale abuse and addiction of narcotics such as amphetamine and cocaine have become a global problem. In this project, we innovatively use graphene quantum dots (GQDs) as a fluorescent sensor to detect and quantify amphetamine and cocaine. This technology will have broad forensic application prospects. READ MORE
