1. 1. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

   University essay from KTH/Fiber- och polymerteknologi

   Author : Murtaza Sharq; [2022]
   Keywords : Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

   Abstract : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. READ MORE

   Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

4. 3. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Emelie Graham; [2015]
   Keywords : Ecosystem Science; Physical Geography; 2nd generation biofuels; furans; tropospheric chemistry; ozonolysis; atmospheric kinetics; computational chemistry; IR Spectroscopy; Atmospheric Science Biochemical Cycles; Earth and Environmental Sciences;

   Abstract : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. READ MORE

5. 4. Atmospheric decomposition of cyclic ethers

   University essay from Lunds universitet/Fysiska institutionen

   Author : Ida Mexnell; [2013]
   Keywords : Atmospheric chemistry; environmental issues; bio fuels; furans; Physics and Astronomy;

   Abstract : Renewable alternatives to fossil fuels are of importance nowadays since the use of fossil fuels is considered to stand for the largest contribution to global warming. In recent years, a group of cyclic ethers called furans have been proposed as potential renewable fuels. READ MORE

6. 5. Furan - A Future Fuel and its Lifetime in Urban Air

   University essay from Lunds universitet/Fysiska institutionen

   Author : Emelie Graham; [2013]
   Keywords : Atmospheric science Tropospheric chemistry Kinetics Rate constant Absolute rate method Biofuels Furan Ozone; Physics and Astronomy; Chemistry; Earth and Environmental Sciences;

   Abstract : With a rising global mean temperature caused by increased emission of greenhouse gases into the atmosphere biofuels are considered as a possible solution to the greenhouse effect. One of the potential biofuels is furans and this report aims to determine their lifetime in polluted air. READ MORE
