Preliminary study on tensile properties of electrospun silica fibers/polypropylene composites

PublicationsLeave a comment

Wanakamol, P. , Boonyaratgalin, W. , Supanam, N. Abstract   Composites based on silica and glass fibers conventionally contain fibers with dimension in the range of a few micrometers to millimeters. Electrospinning technique allows fabrication of fibers in the submicron length scale. With smaller dimension, these fibers when applied as reinforcement in composites may yield…

Harnessing Yeast Peroxisomes for Biosynthesis of Fatty-Acid-Derived Biofuels and Chemicals with Relieved Side-Pathway Competition

PublicationsLeave a comment

Zhou, Y.J. , Buijs, N.A.e, Zhu, Z., Gómez, D.O., Boonsombuti, A., Siewers, V., Nielsen, J.   Abstract   Establishing efficient synthetic pathways for microbial production of biochemicals is often hampered by competing pathways and/or insufficient precursor supply. Compartmentalization in cellular organelles can isolate synthetic pathways from competing pathways, and provide a compact and suitable environment…
