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…
Trace elements and mineral chemistry of silicified wood from Thailand: colours and elemental distribution
S. Saminpanya Abstract Thai silicified woods were examined using electron probe microanalysis, yielding chemical data that characterised the samples into two groups: low and high silica contents (82—94 wt% and 94—98 wt%). The elements analysed in order of abundance include Si > Fe > Ca > Na > Al > Ti > K > Mg…
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…
