We isolated the highly potent attachment-inhibitors (three times more active than standard CuSO4 in the blue mussel assay), trans-6-, 8-, and 10-shogaols, from a hexane extract of the roots of ginger, Zingiber officinale Roscoe. Trans-8-shogaol showed the highest antifouling activity comparable with that of tributyltin fluoride (TBTF), which is recognized(More)
Neocurdione, isoprocurcumenol, and a new sesquiterpene, 9-oxo-neoprocurcumenol, were isolated from fresh rhizomes of Curcuma aromatica and Curcuma zedoaria (Zingiberaceae) as attachment inhibitors against the blue mussel, Mytilus edulis galloprovincialis. The structures of these compounds were elucidated on the basis of spectroscopic evidence.
Fillers in plastic resin can give the local stress to the chip, which causes a single-column-line failure in a sensitive dynamic RAM with marginal sense amplifier circuits. This failure can be improved effectively by employing fillers of small size and/or a buffer coating over the chip.
