The continuing release of carbon dioxide into the atmosphere is a major driver of global warming and climate change with increased extreme weather events. Researchers at Johannes Gutenberg University Mainz (JGU) have now presented a method for effectively converting carbon dioxide into ethanol, which is then available as a sustainable raw material for chemical applications. "We can remove the greenhouse gas CO₂ from the environment and reintroduce it into a sustainable carbon cycle," explained Professor Carsten Streb from the JGU Department of Chemistry. His research group has shown how carbon dioxide can be converted to ethanol by means of electrocatalysis.

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

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.

A very slow day 🫠

studying anachem makes me wanna cry, can my mum just pick me up cmao ~

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…

Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclerosis. A study published in the Journal of Biological Chemistry found a plant-derived flavonoid—a type of chemical compound—called sulfuretin blocked the activity of an enzyme involved in MS and cancer.

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)

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.

Chemistry’s Chameleon: The Self-Repairing Marvels of Chemical Gardens

Chemists have been enamoured with the vibrantly coloured, coral-like structures that develop when combining metal salts in a tiny vial since the mid-1600s.

To date, scientists have been unable to simulate the functioning of these ostensibly straightforward tubular structures, known as chemical gardens, or the patterns and laws that control their development. Oliver Steinbock, an associate professor of chemistry and biochemistry at FSU, described it as "very interesting in a materials context." They don't develop as crystals do. A crystal grows and has lovely, pointed corners.

Chemical gardens typically develop when metal salt particles are added to a silicate solution. A semipermeable membrane that erupts upward in the solution as a result of the dissolving salt's reaction with the solution gives the structure, which resembles coral in appearance, a biological appearance.

The chemistry is associated with the development of hydrothermal vents as well as the corrosion of steel surfaces, where insoluble tubes can develop. The researchers were able to simulate a variety of distinct shape patterns, some of which resembled flowers, hair, spirals, and worms thanks to the constriction between two layers.

The designs could be made up of self-extending filaments, loose particles, or folded membranes, for instance.  The self-healing properties of the material were also shown by the model, which supported observations that fresh membranes expand in response to microbreaches.

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…
