Mechanical properties of compression-molded electrospun silica fiber/nylon-6 composites

Wangworn, P.a, Wanakamol, P.b aDepartment of Physics, Faculty of ScienceSrinakharinwirot University, Wattana, Bangkok Thailand bDepartment of Materials Science, Faculty of ScienceSrinakharinwirot University, Wattana, Bangkok Thailand Abstract In this study, we utilized electrospun silica fibers (ESFs) as reinforcement in sandwiched nylon-6 composites. The silica fibers were fabricated via electrospinning of sol-gel precursor, prepared from tetraethyl orthosilicate.…

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

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

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…

Physical and chemical properties of the ancient glass beads from the highland log-coffin culture and the lowland areas, Thailand: Considerations on their colors and technology

Seriwat Saminpanya, , Natamon Bavornyospiwat, Sunisa Homklin, Sumalee Danyutthapolchai, Pimtida Bupparenoo Abstract The ancient glass beads from a log coffin cave at Pang Mapha, Mae Hong Son as well as from Sa Kaeo, Thailand, were studied for their physical and chemical properties. The samples have an average specific gravity of 2.25, and an average refractive…
