I really don't know about food safe. Or safe for any end consumer, really. They absolutely need to do some severe toxicity testing. Because this funny new glue is an organic phosph…

If it has a concept of data sources and can digest them, sure. Anecdotally, most issues with Excel at my job are caused by data sources being renamed, moved or reformatted, by brok…

Probably more for repairing than producing, in my experience. That stuff's expensive and breaks easily. An old lab joke: Which daily sound scares a chemist the most? - Krk.

One of my elderly colleagues once told me that at the end of each day, they'd put all the lab coats in a big vat of benzene to clean them. The next day, they took them out, let the…

Sweet? I'd rather liken it to period blood, but more metallic and kind of... vicious. Its smell is hardly comparable to its relatives xylene, toluene, ethyl benzene.

Pure silica? It's really just SiO2. It might kind of fragment/ burst if it has a lot of water absorbed and you heat it too fast. Then everything in the vicinity would get sprinkled…

Yeah don't. Like many metals, finely dispersed iron can self-combust on air. I'd suggest an air-tight packaging filled with CO2, or, if your food is susceptible to acid, N2, if at …

You can see for yourself: https://bundeswahlleiterin.de/bundestagswahlen/2025/ergebnis... This shows the winners of the "second vote." Dark blue = CSU (conservative party), its out…

I hardly noticed, and I've been on Lemmy for nearly two years. I think it depends on which instance you sign on to. But a) you can filter out certain topics, users and even entire …

European LNG spot market prices went up by much more than an order of magnitude between Summer 2020 and Spring 2022. They also went up for other regions while Russia has no problem…

I've been in the field for many years and I see the EU on the forefront of public chemical safety, both in terms of legislation and enforcement. ECHA is transparent about glyphosat…

Where I live (EU), lawyers have standard rates for standard stuff. For a run-of-the-mill letter, you're looking at ~ 100 €, but could be 50 if they want to get you as a new custome…

It is now assumed that this already happened, in 2011, in a Bulgarian umbrella attack in Germany's crime capital, Hanover. My somewhat unfounded guess is that the perpetrator himse…

It's a nice step in the right direction, for sure. But, having worked paying jobs in both Chemistry and Product Safety: Not counting latex, nitrile is the bare minimum, really, whe…

I actually had a similar type of dreams as mark_l_watson when I took quantum chemistry (that's not a drug... for most people). Since I switched to performing more mundane tasks for…

>Is reddit really in decline, though? Doesn't seem like it. In fact, arguably things improved a lot in the past year. That depends on your quality metrics, and, of course, personal…

A while ago, out of the blue, I've been diagnosed with a very rare medical condition. Online ads and recommended videos then started showing relevant and very specific drugs, treat…
