Super Bainite: Super Strong Steel
|
Super bainite, a surprisingly-strong steel, is the subject of this week's Naked Scientists. We discover how it's made in the metallurgical equivalent of a pizza oven, why it makes the best bearings and how, even when it's full of holes, it also makes great armour. In the news, a nanotechnological tool to unblock blood vessels, a dust cloud that's disappeared around a nearby star and have we found the Higgs? Plus, can your cutlery affect the flavour of food?

Dear Chris,
Question:
Does metallic cutlery really affect perception of food taste?
For example common wisdom tells that caviar should not be eaten from steel spoons and for gourmet occasions often porcelain or bone spoons are used.
