Today On Adventuresinchemistry: Mouth Pipetting: Horribly Disgusting Or The Most Horribly Disgusting?

Distillation of the reaction product from a pressure tube. 

This picture may look like that’s nothing special with it, but in the receiving flask (left side) there is a really-really special disulfide what I was able to prepare first time in pure form with a high yield. For months I was unable to prepare this molecule with a high selectivity from the starting materials. Always at least 2-5 side products formed and the product was only isolated in a low, 10-20% yield. 

Geminids of the South : Earth’s annual Geminid meteor shower did not disappoint, peaking before dawn on December 14 as our fair planet plowed through dust from active asteroid 3200 Phaethon. Captured in this southern hemisphere nightscape the meteors stream away from the shower’s radiant in Gemini. To create the image, many individual frames recording meteor streaks were taken over period of 5 hours. In the final composite they were selected and registered against the starry sky above the twin 6.5 meter Magellan telescopes of Carnegie Las Campanas Observatory in Chile. Rigel in Orion, and Sirius shine brightly as the Milky Way stretches toward the zenith. Near Castor and Pollux the twin stars of Gemini, the meteor shower’s radiant is low, close to the horizon. The radiant effect is due to perspective as the parallel meteor tracks appear to converge in the distance. Gemini’s meteors enter Earth’s atmosphere traveling at about 22 kilometers per second. via NASA

hey, your blog is super great and you seem like a beautiful human being. i find you to be super inspiring! i know you get a lot of these questions, but is it okay to punch boys who tell me that i "can't can't be an engineer because I'm a girl"?

Not that I’m advocating violence, but if hypothetically you were to punch a shitty dude for being sexist, you should aim for the solar plexus or the stomach, not the face, because you’re less likely to hurt your hand and you’ll do more damage. Hypothetically of course. 

Finally! Something was made what is a critical compound during the production of a quite special amino acid. 

The fun part with this was, that I tried nearly 20 methods to obtain this compound, and all of them failed. At last I tried a Chinese recipe what said that the product will be something that could be easily converted to my molecule, but instead of that compound I got the compound what I need out from the reaction. Better news: 90% isolated yield! 

The use of 3-D printers has opened up the possibility of on-demand implants, prosthetics, and medical devices. This week, scientists reported that they were able to 3-D-print the first stable ear, bone, and muscle structures out of living cells and implant them in mice. The results were published in Nature Biotechnology. Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine and an author on that paper, describes the challenges of 3-D printing living cells and how the technology could be used in bioengineering body parts.

There was a brief period of time my junior year of undergrad when I wanted to be an organic chemist, so I took the graduate level organic synthesis class.

This wasn’t even the advanced ochem class, it was specifically synthesis for actual organic chemists, and it was just me and two other undergrads surrounded by first year grad students.

Anyways, the exams were these hellish two hour affairs which probably stand as the most difficult exams I’ve ever taken, and we all knew they were going to be bad going into the first midterm but not how bad.

So about forty minutes into the first two hour midterm one of the grad students gets up and turns in his test. The rest of us were like still on the first page so we were all kind of impressed that he was done already.

He leaves the room, and then from the hallway we hear him yell “fucking fuck,” and I think that was the purest expression of how midterms and finals feel that I have ever encountered.
