When you see this, what do you think it is? The spring of a mattress? Chains? Threads? Well.. they're all good guesses but are all incorrect! portable microscope portable microscope It turns out, these are nylon polymers connected to create stockings!!! Believe it or not, nylon comes from petroleum, just like how asphalt also comes from it. It is not only sturdy but also flexible! The "chain" like nylon polymers are actually extremely flexible despite its appearance! When I stretched it, I observed the polymers bending to oval-like shapes! A little background history: The nylon stockings were created in 1939 and were also used in World War II for manufacturing tents and parachutes! The stockings were also big in popularity during the mid-twentieth century. The Polyamide is actually very thermal and chemical resistant. Personally, I wonder whet...
Hey guys! So some time ago, I found these colonies of white mold on a potato and decided to check it out! Honestly I find it slightly intimidating how thick a single fungus is (check out the 1000x picture and you'll see what I mean!).
ReplyDeleteIt reminds me of a beehive, but wow 1000x picture drastically changes your perspective on it.
ReplyDeleteYeah it does! What I find weird is that it has a close resemblance to bacteria in the photos. I think it's because the photo isn't showing the best resolution of the fungi like how you'd see it if it were in an electron microscope.
DeleteTrue...I'd expect to see some kind of hyphae make a more concise mycelium. Unless what is in the 400x is the mycelium then yeah okay, I see it now.
DeleteI just realized that when I looked at the cell wall, it looks much thicker than an ordinary cell wall we see in plant cell walls. Is it because they have chitin making up their wall while plants have cellulose?
ReplyDeleteThat would make sense, since chitin is also used to form the exoskeleton of arthropods, it stands to reason that it would have to be thicker or more durable in some way in comparison to cellulose.
DeleteI was just thinking about this but what is the difference between blue and white mold? I know they have different colors but other than that I have no idea what the difference between those two are..
ReplyDeleteI was just thinking this...why are you letting your potatoes get mold?!
