Creative gen. chem exam

It’s summer, hooray! I am currently interning/vacationing in Livermore, so it’d be great if some of you guys can stop by to check on Mitch & Maz every once in a while, make sure they bathe and stuff. They would probably prefer that you bring some brownies, if possible. 🙂

Most of you Reddit addicts have probably already seen it, but I thought I would share anyway. This is one disgruntled chemistry student.

If my professor (or even TA) actually reads what we write on the exam, instead of just selectively scanning for answers, I would probably do something similar. My last creative masterpiece was a half page filled with happy faces on a lab final. The very kind and patient TA that graded the problem is probably reading this blog. 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂 🙂

News from the NanoPutians

Besides having a strange taste in humour, we wacky Europeans are also a bit crazy. Soccer-crazy.

In less than two weeks, the European Football Championship is starting. On this occasion, I would like to present the first bis(alkinylplatinum(II))-based fullerene receptor (1). A fullerene, such as C60 (2) is readily recognised by this box-shaped metal complex. The association reaction can be accelerated by arylacetylene 3, which contains two hydroxylamine functionalities that serve as a catalytic dyad.

You know you’re a Chemist when…

… The Mercedes symbol looks like an eclipsed conformation.
… The first thing you reach for in the morning are your prescription safety glasses.
… All your shirts have holes.
… All your scars are not from bar fights but from chemical burns.
… Someone offers you acid, but its not what you expected.
… Describing sexual positions you use SN1, SN2 and all your friends know what you are talking about. (Theoritically)
… Kids ask you how Santa fits through a small chimney and you reply, “Duh, tunneling effect.”
… You buy a sleeping bag but its not for camping trips.
… You BBQ with the Bunsen burner.
… You say its the size that matters, but you’re really talking about molecular radii.

… You have blisters from playing with your molecular model kit
… You are fed up of people saying alcohol, when they mean ethanol

… You hear the word ‘Molar’ and teeth are the last thing on your mind.
… You habitually wash your hands BEFORE and AFTER using the restroom
… When someone says ‘sodium’ you don’t think about salt, but you think about a clay-like metal that goes well with a big lake.

… You know what saline water is composed of

… You hear “ABS” and you think about acrylnitril-butadiene-styrol copolymer instead of anti-lock breaking system.

… You hear that someone had a bicycle crash and you think that he couldn’t handle working with Naphthalene.

… You stare at the bottle of water and begin to wonder how you would separate all those ions.

… When a friend offers you a glass of amaretto after dinner, you have a sip and say “Ahh, Benzaldehyde…”

… You look at a hexagonal-shaped cookie and think of benzene, not a hexagon.
… I and Me can be iodine and methyl when read…
… OH is a hydroxy group, not Ohio (and I even live in Ohio)

… The stick figures you draw are carbon and not people. (Unless you are CBC)

… when you are humming “dilution is the solution to pollution” while looking at a urinal.

… You put a vodka shot in a 100 ml beaker.
… You use two stirring rods as chop sticks.
… You use the magnetic stirrer as a mixer for your drinks.
… You use the chemostat as an aquarium.
… You use the fume hood as a closet.
… You don’t say table sugar but call it sucrose, and you call common table salt as sodium chloride.

… Someone says, “I love U” and you think they are talking about Uranium!
… You use coke not for drinking, but for cleaning pennies

… You realize your most visited site is not a pornographic one: it’s Chemistry Blog or Chemical Forums!

… You understand these jokes and laughed at them.

Now its your turn to contribute! Leave your jokes in the Comments Section.

Random Science Fact#1: Rhodamine B will stain Polyetheretherketone

Sometimes in lab there will be an interesting result that would be good for fellow scientists to know but is not worth even considering publishing. In that spirit, I bring you random science fact.

In the course of experiments, it became prudent to determine whether Rhodamine B will stain an apparatus made out of PEEK (polyetheretherketone), which is a rather good chemical resistant material. I prepared a 1M Rhodamine B solution in DI water (not all Rhodamine B dissolved by the way) and spun it in an apparatus completely made out of PEEK in conjunction with my undergrad colleagues.


PEEK’s chemical structure is shown above.

Rhodamine B did appear to stain PEEK, where the PEEK had been poorly machined and there were small grooves for Rhodamine B to collect in. Cleaning with a 1M HCl solution and some intense elbow grease action cleaned the Rhodamine B off the PEEK very well. However, the crazyglue that was used to piece together some of the PEEK pieces were permanently stained and no amount of HCl seemed to be able to remove the stain.

This has been a Random Science Fact
