My first router used the Freesco project (https://www.freesco.org/) it had 2 pci network cards in an old pentium 80 that booted linux off a floppy, probably around 1999.
People also don't develop good habits and constantly touch their face with gloves. I worked with surgeons in the hospital and they would point this out. Equally important in a cleanroom.
The stearates aren't microplastics, they aren't polymers, but they have chemical/spectroscopic similarity that results in them confusing the microplastics assays.
That does seem like an oversight. We routinely run process blanks for elemental analysis at my job. I guess if the metal substrates had specifications on no particles you might skip this, obviously a big mistake if another step (ie. handling with gloves) introduced contamination.
In surface science the baggy clear polyethylene are widely known to be cleaner than other options.
I guess with Raman I can see this being misidentified but I do testing with FTIR at my job, although not often for microplastics and we often detect olefins and stearates and they don't seem to get confused. I didn't realize there were stearates on nitrile gloves, we'll need to be more careful of that. We are always weary of protein contamination from people, or cellulose/nylon from clothing.
My M4 Air was $750 on black friday 2025. I bought it after I cracked the screen on my M1 and the cost to repair was half the cost of the much newer computer.
