- blululu 4y agoDiatoms are of the more enjoyable things to look at through a microscope. Google Arts and Culture ran a post on this collection a while back that has some really good photos: https://artsandculture.google.com/story/diatoms-of-the-academy-of-natural-sciences-of-drexel-university-academy-of-natural-sciences-of-drexel-university/BwWh7EaVlShRLw?hl=en https://artsandculture.google.com/story/diatoms-of-the-acade...
- avsteele 4y agoIf you want to see an elemental map of a Diatom you can take a peak at some data collected on one with my company's new instruments. https://zerok.com/assets/slides/MM2022_Vendor_Tutorial.pdf https://zerok.com/assets/slides/MM2022_Vendor_Tutorial.pdf slide 28 Background: This is SIMS data (https://en.wikipedia.org/wiki/Secondary_ion_mass_spectrometry https://en.wikipedia.org/wiki/Secondary_ion_mass_spectrometr...). We have a new instrument can perform these analyses at much higher resolution than has been possible historically.
- twic 4y agoDiatoms are pretty cool. Their frustules (shells) are nanostructured pure amorphous silica, which gives them interesting and possibly useful optical properties: https://pubs.rsc.org/en/content/articlelanding/2020/fd/d0fd00031k https://pubs.rsc.org/en/content/articlelanding/2020/fd/d0fd0... https://royalsocietypublishing.org/doi/10.1098/rsfs.2018.0031 https://royalsocietypublishing.org/doi/10.1098/rsfs.2018.003... Some pictures of the frustrules, with some words and diagrams too: https://www.frontiersin.org/articles/10.3389/fmars.2018.00125/full https://www.frontiersin.org/articles/10.3389/fmars.2018.0012...
