Talk:SEAgel

Aerogel was invented 1931, how can SEAgel be invented before when it was invented 1992?

Thanks. I corrected that statement. ⇒ JarlaxleArtemis 03:35, 25 January 2006 (UTC)[reply]

I removed the phrase "or used to control the properties of semiconductors". The grammar appeared to indicate that SEAgel itself is used to control properties of semiconductors, which I believe is incorrect. More likely, it was intended to further explain the term "doped", but if so the grammar was unclear at best and also quite misleading -- I'll provide a link to the Doping article for those who don't know the term.

Claim it will float if filled with hydrogen seems untrue according to info given under standard conditions. "At sea level and at 15 °C, air has a density of approximately 1.225 kg/m3" - wikipedia density of air. kg/m3 = mg/cm3, first side is 1 million times bigger than other side as volume is cubed. So therefore 1.5-50 mg/cm3 is slightly more dense than air unless that counts air inside the matrix.174.3.135.28 (talk) 02:23, 6 August 2013 (UTC)[reply]

Patents expired/expiring?

The references suggest that the patents expired several years ago due to a lapse in maintenance fees, but there is also a disclaimer saying this conclusion might not be reliable. However, it still looks like one of the patents unambiguously expired in 2013, while the other will expire in March of 2014. If someone stumbles across this page after March 2014, it might be time to change the text so say the gel was covered by those patents. Maghnus (talk) 03:50, 18 January 2014 (UTC)[reply]

Hard? Soft?

is it basically styrofoam to the touch? foam rubber? a hard plastic?

if i had a magic substance FLOATING IN MIDAIR, i don't think "insulation!" would be the first application i'd think of.... 173.9.95.217 (talk) 21:48, 21 February 2017 (UTC)[reply]
