1. The significance of ethylene and ethylene response factors in wood formation of hybrid aspen
Sammanfattning : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. LÄS MER
2. Crosslinking of Ethylene Copolymers
Sammanfattning : The chemical reactions taking place when crosslinking poly(ethylene-co-vinyltrimethoxysilane) (EVS) have been studied. Films of EVS were stored in water at 90 °C or treated at processing temperatures in a tubular oven. The different chemical groups involved in the reactions were then followed by FTIR after different treatment times. LÄS MER
3. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae
Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER
4. Ethylene in conifers : involvement in wood formation and stress
Sammanfattning : .... LÄS MER
5. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites
Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER
