Petroleum Jelly was first discovered when a chemist visiting an oil rig noticed that the workers would smear the wax that built up on the drills and rigs on their wounds to heal them faster. He figured out how to refine it and started selling it under the name Vaseline.
OH MY GOD. Thank you SO SO SO much to everyone who came out to my show last night! You guys are just too great. I never thought I would step out and see a line of people waiting to get in. It was a HUGE success and a blast! I will be posting the left over pieces on my store and list them later this evening for anyone interested in snatching up any of remaining works!

cozy and warm here while studying for Physical chemistry Test Tomorrow 🎋 So happy with what my mom bought me yesterday, I’ve been looking for a mini canvas with easel for my desk and finally I’ve got one. Happy Sunday Everyone, Enjoy studying xoxo
Preparing myself tonight for a quiz on Tuesday on Organic Chemistry (as always, my dreadful subject) and organizing tasks for next week.
And today I managed to buy some coloured flashcards and I like how smooth it is to write on; makes me want to study more! 😍😍😍
PS: My bullet journal looks untidy though ://
“It is hard to imagine that in this immense universe there aren’t countless planets with some form of life. That life is likely to be very different from our own, given the major role of random chance in the evolution of life. All we know about our kind of life based on carbon chemistry is that it developed very easily and quickly on Earth once the conditions were right. We also know that the chemicals needed for our kind of life, including amino acids, are very plentiful in space. We just have not found any evidence yet for extraterrestrial life because of the immense distances between stars.”

first time revealing my little bullet journal but anyways I’m determined to finish my macromolecules notes tonight (esp bc I procrastinated throughout the weekend) seriously too much things to do with so little time 😿
btw reblog/like this and I’ll check out your blog (esp studyblrs!) 🌵✨
Seeing is Believing: High-Resolution Transmission Electron Microscopy (HR-TEM)
Most chemists, past a certain level of schooling, will have heard of X-ray diffraction; it is a technique used for examining molecular structures and atomic packing in crystalline materials. But, it isn’t without its downsides.
X-ray diffraction needs large single crystals of the sample, which depending on what the sample is, could be devilishly hard to grow. These large crystals in themselves can be problematic as a crystalline structure will be a lot more regular than the amorphous states of the same material. HR-TEM might be solving those problems.
HR-TEM has already made waves in the scientific community as it has been able to allow the viewing of the structures, movements, and reactions of small organic molecules.
The images above show the visualizations of Py-1-SWNT and Py-2-SWNT, the products of the visualised reactions, respectively.
As shown in reaction scheme A, pyrenes were attached to purified single-walled carbon nanotubes (SWNTs) by the direct addition of 4-(1-pyrenyl)phenyl (PP) radicals to the nanotube sidewall, giving Py-1-SWNT.
Reaction scheme B shows the comparison for a two-step method including the Suzuki coupling reaction, giving Py-2-SWNT.
Hi. I was wondering how do you show chemistry between two characters? I've never really understood the concept in media before. If it helps, my story involves two best friends becoming girlfriends. Help?
I think an important part of showing chemistry between two characters is to make sure you aren’t making the characters too similar–they need to have differences, and have chemistry despite those differences. Another thing to avoid doing is making their relationship perfect. Make sure they have some kind of conflict or argument; the key to a good relationship (and showing chemistry between to people) is not that they don’t argue, but that they successfully resolve the argument, even if it means they agree to disagree.
I don’t think I answered this question very well, so try reading this and this for some more ideas!
