1/8 Despite what @physorg_com says, TNTNB will not "play an important role in mining and engineering applications, pyrotechnics, space exploration, or military weapons systems."In fact, it will play zero role. Let me explain why.
#ChemTwitter @physorg_com… 2/8 First, TNTNB decomposes at 65 C. That alone precludes its use in the form of any of these aforementioned applications. That decomposition temperature for an explosive material is too low for any practical use, be it for military or civilian applications.

1/7 A bit of chemistry of the Atlas V rocket. Initial liftoff is achieved with “booster” solid composite propellant that contains ammonium perchlorate, aluminum powder, and hydroxy terminated polybutadiene (HTPB) as the binder system.

#Chemtwitter #Space #STEM 2/7 Aluminum only makes up a small amount of the overall formulation of the booster, but is very important. It catalyzes efficient and clean combustion, and maximizes the burning rate of the solid booster propellant mixture.

1/6 If you get invited for an interview, then it means that the organization asking to interview you is genuinely interested in you, your skill set, and what you potentially have to offer. So know this going in.

@PhDVoice #phdchat #AcademicChatter #AcademicTwitter 2/6 To do well in an interview, you will need to talk about your accomplishments. Talk about your research, what you did that advanced the knowledge of the field, and how you can work well in a team environment.

(1/25) I am writing this thread concerning grad student life in organic synthesis. Some folks will agree with it (though perhaps not openly). Others may be very upset. Either way is OK. But here are some stories, thoughts, and advice

#chemtwitter #realtimechem @RealTimeChem (2/25) I began grad school in June 2004, working in the lab of (now retired) Prof. James A. Marshall. He was one of Prof. Ireland’s first graduate students (1957-1960). I joined the Marshall group not because it was easy, but because it was hard. The hard is what made it great

(1/5) My two cents from someone in the energetic materials arena. Med chem is equivalent to small molecule discovery of new explosive and propellant ingredients. Process chem is the scale-up of these materials for testing purposes.
#chemtwitter #RealTimeChem @RealTimeChem (2/5) In the discovery phase, cost of reagents, cost of synthesis, and length of the synthesis route aren’t an immediate priority. Goal is to make the new stuff, and get preliminary data to see if it’s even worth scaling-up.

(1/25) Having received some DMs on the subject, I would like to tell you all about military technologies, and how they impact our daily lives. This will be a long thread that I hope you’ll read and think about.
