They look at the thermal properties of different cups and the effect of preheating on espresso cups. Interesting read!!
(There are three articles with the other 2 being in the left hand column)

thanks for sharing.  it's interesting, but as far as I can tell, only three cups were compared.  I would be happier if whomever wrote the article would have concluded that of those tested the Bodum cup holds heat best, rather than making a blanket statement that the Bodum cup is the best cup for espresso.

There is s similarly designed cup (double wall with air layer insulation between them) available through 1st-line made of stainless steel... http://www.1st-line.com/store/pc/Frabosk-c394.htm ...which likely retains heat even better than the thin wall of glass used in the Bodum.  I suppose I could run an experiment comparing them (though I wouldn't write a scientific paper about it), since I actually own both.  Maybe I'll put it on my list of "coffee things to do"?

My guess would be that the double-wall steel cup doesn't hold heat as well as the Bodum since steel is a better heat conductor than glass.

This may be an issue with cappucino/latte cups, but I doubt anyone expects an espresso to remain at original temperature five minutes after the pull.

true on the conduction issue, but the steel is pretty hefty and the glass is rather thin, so I'm thinking that maybe the bulk of material in the steel cups makes up for it's better ability to conduct heat.  you know...you're just making me want to run a short test...did you do that on purpose ;)  Unfortunately, I only have the Bodum cups in the latte size, but since I own the Frabosk's in all three sizes, I can do that latte cup comparison.

and yeah, who ever still has any espresso siting in their cup 5 minutes after it's drawn?  Well, maybe some italians, but not me, that's for sure.
