1. 16. Synthesis and Characterization of Copper Halide Complex Materials

   University essay from KTH/Tillämpad fysikalisk kemi

   Author : Hiroki Tomita; [2021]
   Keywords : Copper halide complexes; Coordination polymers; Photoluminescence; Bidentate ligands; Applications of thin films; Kopparhalogenidkomplex; koordinationspolymerer; fotoluminiscens; bidentata ligander; tillämpningar av tunna skikt;

   Abstract : Energiförbrukning är ett hett ämne i världen idag, eftersom världens befolkning fortsätter att växa. Som ett resultat ökar också den globala energiförbrukningen snabbt och utsläppen av koldioxid därmed, vilket påverkar global uppvärmning och klimatförändringar. READ MORE

3. 17. Method development for a tribological diffusion couple of rock and cemented carbide

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Alma Fjällström; [2021]
   Keywords : Diffusion couple; tribology; cemented carbide; rock; granite; sandstone; Silicon; rock drilling;

   Abstract : In a diffusion couple, the intimacy of the contact between the two parts is of high importance for the results. In a tribological contact, matter can transfer from one part to another and a very intimate contact is formed. READ MORE

4. 18. Electrical wiring of Shewanella oneidensis MR-1 with osmium polymers of different redox potentials

   University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Beräkningskemi

   Author : Laleh Tavakoli; [2021]
   Keywords : Analytical Chemistry; Bio-Analytical Chemistry; Electrochemistry; Bacteria; Osmium redox polymers; Shewanella Oneidensis MR-1; electrode; Microbial electrosynthesis; Electron transfer; Chemistry;

   Abstract : The results of studies have shown that the several applications such as microbial electrochemical system (MES), bio-electrochemical systems (BESs) and production of beneficial chemicals are due to electrochemical connection among electrodes and microorganisms. The following two factors are important in choosing the microbe mediated electrochemical biosensors: I) Binding of bacterial cells on the electrode, II) Efficient electron transfer (EET) between the electrode and the cells by a mediator.

5. 19. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Cecilia Nemeth; [2020]
   Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

   Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

6. 20. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Nathan Ullberg; [2020]
   Keywords : backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

   Abstract : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.
