Smart Surfaces in Biobased Materials
The self-assembly blends of cellulose propionate (CP) and fluorine (F)-containing cellulose derivatives was examined on a model system of solvent cast films. The F-containing derivatives were either high molecular weight statistical cellulose esters with a number of F-containing substituent evenly …

Developing green processes for the conversion of biobased materials into pyrones
<p>The work disclosed in this dissertation implements bio-based material for new synthetic applications. The synthetic applications are corrosion inhibitors, plasticizers, and block copolymers. Triacetic Acid Lactone (TAL) is a bio-based molecule fermented from Saccharmyces cerevisiae. In the first …

Synthesis of a renewable sourced thermotropic polyester with 2,5-furandicarboxylic acid
With the rapid depletion of non-renewable sourced materials, unpredictable fluctuations in the prices of fossil fuels, and increased environmental awareness the need to develop biobased materials grows ever more desperate. Furan derivatives sourced from hexoses provide a promising solution for …

Polyurethane foams containing renewable castor oil replacement
… to the shortage of fossil resources, renewable biobased materials are studied as alternatives to petroleum. In this project, castor oil was chosen as a renewable biobased polyol in order to replace the nonrenewable petroleum-based polyols. Water-blown rigid foams were made from polyols with …

Sustainable food process engineering
… challenges due to the dependency on fossil raw materials and the accumulation of durable single used packaging waste. Therefore, food packaging innovations need to be adjusted to the new demands, by not being an environmental burden, but still providing product protection, safety, and supporting …
