1. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials
Master-uppsats, KTH/KemiSammanfattning : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. LÄS MER
2. Transient state UV spectroscopy of Tyrosine and Tyrosine-containing protein
Master-uppsats, KTH/Tillämpad fysikSammanfattning : The aromatic amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies. These investigations extract information on protein conformations and interactions from the emitted fluorescence's intensity, wavelength, and/or polarization. LÄS MER
3. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER
4. Chemical analysis of polycyclic aromatic compounds in plastic materials used in indoor environments
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Human bodies are in constant interaction with materials containing known and unknown chemicals of hazardous behavior. One group of chemicals are polycyclic aromatic compounds (PACs) which can be present in both indoor and outdoor materials, commonly in plastics. LÄS MER
5. Kvantkemisk förutsägelse av regioselektivitet och reaktivitet hos SNAr-reaktioner
Kandidat-uppsats, KTH/KemiteknikSammanfattning : Multivariate regression of several different quantum chemical descriptors was used to build a model for the reactivity of nucleophilic aromatic substitution reactions, i.e. SNAr reactions, through predictingthe molecular reaction site’s Gibb’s free activation energy (ΔG‡).
