thumbed up for that professor phone call
=D The Professor is so nice!
It's neat seeing someone so traditionally educated explaining "Give me a moment, I'm making a RUclips video" =) Thank you! We love your videos!
Great to see that Professor Poliakoff had his professor hair even before he was a professor. :-)
4:23 this should totally be a pokemon
I can't express in words how awesome this professor is!
Vileplume!
haha I just got done synthesizing monoacetylferrocene and 1,1'-diacetylferrocene in organic lab!
That was sublime.
The funny thing is, when he pulled out the two dog toys and the yellow ball I immediately thought that the structure was probably like a sandwich.
I remember making ferrocene and acetylferrocene in chem lab, man I miss those days, if I lived somewhere important, I could be putting those skills to use. But man the memories...God I love these videos!! And yes, the Professor shares a likeness I do; finding chemical structures in the mundane, for example, a hex nut is a perfect example of benzene, and chickenwire is an excellent representation of a graphene sheet. Yes, I can say with a passion, I love chemistry, always have, always will!
5:20 in the captions: "org and the metallic chemistry"
That would be quite an unusual band name...
heh, this just shows I really know nothing about chemistry. Loved it!
What I want to know is who called? :)
Really interesting... there's so much to know about chemistry that I never would have imagined.
i worked with ferrocene in graduate school. we bonded two molecules of anthracene to the rings. the electro-dynamics of that compound were very cool. very very interesting molecule!
i so want to come and study on your university it is awesome !
Please never stop making cool videos like this
Great as always :D.
Cyclopentadienyl (anion) is aromatic like benzene.
Thanks. Any chance you'll be doing one soon on ammonia? Or a video on one of the standard pH indicators and its color-change chemistry? It would be great to have those for teaching, to supplement the one you did on HCl.
thanks for help revising for my chemistry degree
wow what a beautiful lab!
During my summer undergrad lab we got to sublime ferrocene very slowly to make nice big flaky orange ferrocene crystals.
From watching these videos I have mostly learnt that dog toys are modelled on various molecules. I wonder if there's some frustrated chemist in a dog-toy design company somewhere.
Safety, and the fact that it heats very evenly. An open flame in this case can produce a grave fire risk.
I love your videos
Wow... that lab is huge!
"because I am making a video" - Haha great :D
if there is any pokemon fans out there, this video helped me learned something that might be clever on game freaks part!
ferroseed is metal grass type, organic and inorganic. ferrocene established the field of Organometallic chemistry which concerns the chemistry of compounds where you have carbon boned directly to a metal, organic and inorganic!
of course i could be looking way into this.....
LOVE THE TIE =D!!
Normally Brady's videos are 100% fluid and beautifully informative but I really fail to understand why it suddenly cuts to Ferrocene sublimation..? Can someone explain this?
I was expecting to see an "extra footage" to shed some light on the matter but I see no such video.. :(
6:40
I love that visual representation of heat :D
5:49 Young Professor has awesome hair, too. COOL!
2:28 You gotta love this guy! :D
Wow, how old is the professor?
I love the videos hope to see many more.
the piano stool is so cute!
I think it was great that you left the fone call in the video:).
that's actually why i clicked on this video, i was watching a video from periodictable channel and they were talking about perfumes, and then i saw vileplume and i thought it had something to do with it. it reminded me of that pokemon episode about perfumes...
i like the editing
Guys, try to turn on the captions and watch the video with reading them, it is hilarious.
Its the additional pi electrons, as opposed to the additional carbon, that are more fundamentally responsible for the stability.
if it was energized in space and turned to gas form, then cooled down but there was nothing for it to cling to, would it crystallize to itself somehow? Or stay a gas forever until the first impurity? Or maybe a simpler way of asking is, do crystals always have to have an impurity to start the crystallization process?
Your videos are the best, thank you all!
why is it darker at the top? is it burning? or is that to do with the new crystals?
I love your videos, making science interesting and fun for everyone!
The 'piano stool' molecule looks like a Vileplume from Pokemon!
@bbsonjohn I think what's happening is that the ferrocene closest to the glass is heating and subliming into gas so that there is a sort of cusion of gas between the solid ferrocene and the gas (a bit like with a hover craft)
With the gas being pulled up into the vacuum it 'knocks' the solid around causing it to move around and give the impression it's bubbling.
It is interesting molecules like this that have made me take chemistry for sixth form.
I'll bet he has a little playroom full of them, where he does his thinking.
@Serostern
I think because that way the molecule can depose quickly enough. A Bunsen burner may keep the molecule too hot for too long.
Oh my god the hair in the photo! Is that a sublimation reaction too?
@Serostern It can be adjusted for making the flame hotter or cooler, however, I still believe that the flame will heat the ferrocene too much to before it loses enough energy and deposits into it's solid form again.
6:20 are the powder "bubbling"?
I have one of those wooden things with the smiley face!! They're used to massage your muscles haha
I find this funny considering organometallic compounds have been known before ferrocene, including the infamous tetraethyl lead.
I would like to give thumbs up (as usual for these great videos!), but it's been deactivated. So in written form: thumbs up!
@verybiggun
Yes, but it was the discovery of metallocenes like this which really made the world of chemistry excited about organometallic chemistry.
@Cellogamer But a bunsen burner can be adjusted for that reason?
I don't really know =P
Very informative viedo :)
What about Nickel Carbonyl....surely that is an organometallic compound that was discovered before ferrocene?
@leungclj Chemists never use (bunsen) burners in labs because there are too many solvents that are highly flammable - chemists try to be as safety conscious as possible. You can get the same effect with blow guns or 'hotplates' as you would with a burner anyway
and only 5 people left comments about his hair in moscow! take a closer look... it made me and my family laugh out loud.
1:43 "....that in the early 1950s a chemist called..ring.... " lol
nice video
I wonder what company made those toys? They'd probably be tickled to see this :D
Yes, cyclopentadiene is incredibly unstable. Its flashpoint is 25 degrees Celsius.
Organo-metalic chemistry example:
Hemeoglobin in the red blood cells.
This is AWESOME! I love your videos! :-)
Can I...can I call you back in a littl'while? I'm just making a video...bye!
Hahah.
@TheBetterGame Because heat guns are safter, generally most labs try to avoid open flames these days.
What about C5H5+?
@ImAmWatching exactly.
Leaves me wondering what are the specific physico-chemical properpites of molecules which prevents them from being liquids.
We want more organic molecules =D.. How about some carbohydrates?
I think sugars are one of the most hard things to study, and would help many if periodicvideos gave a hand =)..
Sincerely, a chemical engineering student.
5:52 , did the professor ever NOT have scientist hair?
His son had a frog which now lives in the university and he has to go and buy food for it, it's in one of the videos
@doctorlady4637 i made synthesize it too last semester ;)
But what happend if u add nitric acid to it?
thank you professor for putting us first!
niobium seems to be a very optimistic "chipper" element :o)
5:58
Youger days, and still...
DAT HAIR.
2:26 LOL
4:20 smiley face :D
thinking about c5h5 and palladium
everything can sublimate under the right conditions, as long as it doesn't decompose
@ImAmWatching I did chemistry at A Level and, although I wasn't very good at it, it is a great subject to take. It's hard, but well worth the effort.
One tip... never trust the soap!
Someone get the professor a pair of psychodelic glasses!
nice tie
I think the Professor spend a lot of his free time in the pet shop
The dog toy looks like a zeolite too!!
Ferrocine is an ice cream sandwich
2:50 Is that a Cadbury Creme Egg below the computer?
Somehow I found this video absolutely hilarious.
niobioum with the ferrocene hat looks like the pokemon Vileplume!! (dude.. i need friends)
Normally, I can remain fairly adult about the hair, but to see it in the earliest stages of its life was almost shocking. What's the earliest shot of that hair that exists?
Why a heatgun instead of a bunsen burner?
Reminds me of a TIE fighter.
why use a heat gun and not a Bunsen burner???
@TheChopstixofdoom
It's a representation of the cation of cyclopentadiene (C5H5-)
I love the absurd veriety of objects the prof uses as models
Wow! Very dramatic first 30 seconds! I went from thinking the Professor had a fetish for chewing dog toys, to briefly thinking he had an interest in witchcraft.
OH IT'S A PUMBLOOM!
can i call you back? i'm making a video. he said that so seriously that it was was funny
The piano stool is more of a vileplume.
