8:08 AM | A convenient method to chemically modify boron nitride nanotubes
So far, it has been generally accepted knowledge that boron nitride nanotubes (BNNTs) are highly inert to oxidative treatments and can only be covalently modified by highly reactive species. By contrast, oxidation of carbon nanotubes has been proven very convenient and fundamentally important to modify the nanotube structure and morphology via controlled corrosive effects. Now, researchers have discovered a convenient method to disperse and chemically modify the morphology of BNNTs by […]

2:44 AM | How Robin Williams helped me out in graduate school
Spring 2004. I was a callow first year graduate student, with an insouciance and naiveté befitting a first year graduate student. At that point like most of my fellow grads, I was hungry for knowledge and thought that everything that I needed to know would be found in books and lectures. Lab work was simply a question of putting some of this knowledge into practice and producing a passable PhD thesis.I was a voracious reader and used to check out as many books on chemistry, physics, drug […]

12:04 AM | MDMA isn't an amphetamine?
Dallas Cowboys' defensive back Orlando Scandrick was suspended today for four games due to a positive urine test for MDMA. Scandrick’s story consists of an excuse that he was in Mexico on vacation and was persuaded by a friend to add a substance to the beverage that they were consuming. Allegedly he did not know the identification of the substance he ingested.In an article from ESPN.com, it is stated:“While MDMA alone would be considered a drug of abuse and would not subject […]

7:26 PM | How Some Nanoparticles are Like Chocolate Chip Cookies
Synthesizing nanoparticles is sometimes a lot like baking cookies. You start with ingredients, mix them together, and put them in the oven. After a few hours, you take them out and admire your hard work. Just like there are lots of different kinds of cookies, there are also many different kinds of nanoparticles. The easiest […]
