>Why does pointing a laser at graphene oxide reduce it?
It breaks the bond between the carbon and the oxygen.

>Do you release molecular oxygen?
Yup. Also, I'm guessing some other byproducts. If I get the chance, I'd like to analyse them via ICP-MS.

>What wavelength do you use?
A usual LightScribe laser. 780 nm.

>What's stopping the oxygen from just reacting with the graphene again?
The same reason you don't spontaneously combust, even though there's oxygen in the air - activation energy.

>I tried repeating this experiment in HS Chem, small explosion shattered the test tube.
That's why I took Humer's Method as a blueprint for my synthesis. Brodie's method is quite dangerous and cooling everything with an ice bath is a must - regardless of the method of preparation. Maybe you didn't cool it enough or took too much oxidation agent and produced a shitton of carbon dioxide?

I can't see why anyone would use LaTeX anymore. Nowadays, there are several (non-Microsoft) alternatives which are faster, more productive and wysiwyg. Hell, they even have an equation assistant. I've tried to write some protocols and lecture scripts in LaTeX but I needed about five times longer than just writing everything down in OpenOffice and then exporting it as a pdf.
Why would anyone use it? Srs question
