“每日科技报告”第9期 Unusual Snail Shell Could Be a Model for Better Armor
Deep within the Kairei Indian hydrothermal vent field, two-and-one-half miles below the central Indian Ocean, scientists have discovered a gastropod mollusk, whose armor could improve load-bearing and protective materials in everything from aircraft hulls to sports equipment.A recently discovered gastropod from the Kairei Indian hydrothermalvent, called Crysomallon squamiferum, has an unusual shell structuresuperbly suited for protecting it against penetration attack.
Researchers at the National Science Foundation-supported MaterialsResearch Science and Engineering Center at the Massachusetts Instituteof Technology are studying the mollusk's physical and mechanicalproperties. A report, "Protection mechanisms of the iron-plated armorof a deep sea hydrothermal vent gastropod," appears this week in theProceedings of the National Academy of Sciences.
The so-called "scaly-foot gastropod," has a unique tri-layered shellthat may hold insights for future mechanical design principles.Specifically, it has a highly calcified inner layer, a thick organicmiddle layer. But, it's the extraordinary outer layer fused withgranular iron sulfide that excites researchers.
The Kairei Indian vent field is a series of deep gashes in theplanet's su**ce along a volcanic mountain chain below the IndianOcean. There, researchers on an expedition discovered the never beforeseen snail in 1999.
