Phospholipid fatty acid composition of nine marine sponges from Qatar
(
IFREMER
, 1998 , Conference Paper)
Phospholipid fatty acid composition was studied in sponge from Qatar including eight Demospongia and one Calcarea. More than 60 fatty acids were identified in each species as methyl esters and N-acyl pyrrolidides by gas ...
Hybrid plamonic conductor-gap-silicon microring-on-disks electro-optic modulator
(
Institute of Electrical and Electronics Engineers Inc.
