1. 21. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB

   University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

   Author : Magnus Kemi; [2023]
   Keywords : bio-energy; biomass; coal; greenhouse gas emissions; industrial residues; LCA; LKAB; logging residues; iron ore; pellets; sinters; willow; sustainability;

   Abstract : Iron production accounts for substantial shares of global coal use and GHG emissions. LKAB is Europe’s largest iron company and Sweden’s fourth-largest emitter of GHGs. To reduce its emissions, LKAB might implement biomass in iron ore pelletisation. READ MORE

3. 22. Characterization of Mitilysin Pores by Cryo-electron Microscopy

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Vladimir Novakovic; [2023]
   Keywords : Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

   Abstract : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. READ MORE

4. 23. Exchanging 'Life' for Money? Overtime work culture and professional women's fertility intentions in China

   University essay from Lunds universitet/Graduate School

   Author : Jinxuan Lu; [2023]
   Keywords : Fertility intention; Overtime work; PLS-SEM; Vignette experiment; Theory of Planned Behavior; Social Sciences;

   Abstract : In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertility intentions among working women of reproductive age in urban China.

5. 24. 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

6. 25. Geobacillus 7349 – A new potential biosurfactant producing microorganism

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Zhuoying Deng; [2023]
   Keywords : biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

   Abstract : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. READ MORE
