#Analytical chemistry

Nearly all technology today—from cellphones to computers to MRI scanners—contains rare earth elements (REEs). The global market for REEs is predicted to reach $6.2 billion (USD) this year and $16.1 billion (USD) by 2034. High concentrations of one particular REE—lanthanum—are often found in mine tailings. Runoff from this waste can make its way into nearby bodies of water where it poses a risk to human health and the environment. As a result, researchers are on the hunt for ways to recover the material.

I hate that analytical chemistry is called that how I am supposed to take an article seriously that’s published in a journal called Anal. Chem.

Learning about Kendrick mass defect plots 🤍

It feels good learning about things that directly apply to my research 🔬

Sigh, I’ve been trying to study all week but lately the work I’ve been doing for my research lab has been going nowhere and it’s left me unmotivated…I went on a walk

A very slow day 🫠

Colorcoding and planning out my next semester. I love being a double major guys I swear I love it so much 😭

In reality I dunno what I'd do if I had to choose either english or chemistry. I need both! I am really excited for this semester to start up....or maybe I'm just anxious and want to overplan to make up for itttt. I get to TA a class this semester which is exciting but I'm also quite nervous for that, along with my physical chemistry class.

I'm also not super excited to go from my chem class to my english class and then back to the chem building for analytical lol. But at least I get to sleep in a little bit this semester! And I am so so excited for my english classes, especially my Octavia Butler one.

Bromocresol green (BCG) is a dye that is used in chemistry and analytical chemistry as a pH indicator in acid-base titration and in thin-layer chromatography staining solutions to visualize acidic compounds. Generally, the indicator can be prepared by dissolving BCG in an ethanol solution.

Parts per million (ppm) is a way of expressing very dilute concentrations of substances

Parts per million (ppm) is a way of expressing very dilute concentrations of substances. To calculate ppm, you can use the following formulas depending on what information you have. Mass base example   volume base calculation   Practical Notes For dilute aqueous solutions, 1 ppm is roughly equal to 1 mg/L. For gaseous mixtures, 1 ppm is often taken as 1 µL of gas per liter of air. Summary PPM…

Adhesives are everywhere, from the tape used in households to the bonding materials in vehicles and electronics. The search for stronger, more adaptable adhesives is ongoing and may come down to adding a dash of salt to two special polymer ingredients known as polyzwitterions, or PZIs. New research from a FAMU-FSU College of Engineering team led by Hoyong Chung, an associate professor in the Department of Chemical and Biomedical Engineering, shows a new way to create adhesives by using the natural attraction between positively and negatively charged materials. The work was recently published in the Journal of the American Chemical Society.

Spending nearly 5 hours on an assignment worth only 2% of a mark normally doesn’t feel great but my grad student mentors said that my rough draft exceeded their expectations and they had no big comments on the final draft and that’s worth soooo much more to my ego than 5 hours teehee.

Is there a good way to get access to a mass spectrometer as an amateur chemist? I want to synthesize e.g. aspirin and verify the purity

(I understand that this is not the same as it being safe to take if the mass spectrometer only shows peaks corresponding to the product. I'd still be curious)

Understanding Chromatography: Function, How it Works, and How to Use It

Chromatography is a powerful technique used in laboratories for the separation, identification, and quantification of mixtures. It is based on the differential distribution of components in a mixture between two phases: a stationary phase and a mobile phase. The stationary phase is a solid or liquid that is held in place, while the mobile phase is a fluid that moves through the stationary…
