The world's Most Powerful Microscope. Lawrence Berkeley National Labs just turned on a $27 million electron microscope. It has the ability to make images to a resolution of half the width of a hydrogen atom. This makes it the most powerful microscope in the world...well, maybe not.... Everything is getting smaller! Our phones, our TV parts (flat screen), computers...as this technology gets smaller so do the parts inside get smaller! The newest microscope was unveiled last month: a $5.5 million Nion Hermes Scanning Transmission Electron Microscope that scientists are saying is one of only three in the world. It can image objects a million times smaller than a human hair. Why do we want to see things in such tiny detail? Because we have to! Keeping up with technology requires parts to become super small, even down to the size of an atom. When playing with atoms and modifying a material even by one atom or two could change its properties. Think about wonder material graphene, for instance: a 2D sheet of carbon atoms. Add another atom here or there and you've changed the material and modified what it can do. Keeping an eye on the exact structure is therefore very important. Graphene can be used to hold heat out and keep tiny electronics cool. Another 2D material, molybdenum disulphide can be used as an industrial catalyst, for example to remove sulphur from fossil fuels and make them cleaner to burn. Scientists are even looking at nanomedicine, finding a way to transport medicine using a tiny vehicle to take the medicine to the exact place in the body its needed. Electron microscopes are showing us the close ups of things that are really "far out"...

Wow this feels so weird I haven’t post on the blog in a long time! I’m just going to talk about today! Well I woke up went to the orthodontist and got my braces off 😀😀😀😀😀😀😀😅😅😅😅😅😅😜😆😆😆😆! But then I figured out that I have a cavity behind one of my front teeth so they can’t put my top permanent retainer on yet so today at 3:25 I had to go back to the orthodontist to get a clear top retainer until I go to the dentist and get the cavity filled in!! I know a lot of info in just a couple sentences!

I AM SO SAD!!!! I FEELL SOOO BAD FOR YOU BEN. $27 million dollars!!!! that microscope must be crazy good at its job!!! only three in the world! what if the tecno. gets to small and, like you cant see it or your fone flys away. wow carbon is so wierd. i wonder what would happen if we changed helium? canyou bring my question up in class, and mabey the anserw? i liked the smily face gif. what was the point of it. interesting machines they are making. are they realy small enough to protect an electron? well at least they are using that wierd molicule machine for a good, medicine related use. haha. i also love the harry potter and the sorcerers stone gif.

i am so glad that we humans can start to see atoms. Mrs. Taylor i was thinking that since every thing is made up of atoms i was wondering is it possible that atoms can form atoms but we don't knoww about it yet because they woud be to small then i hope that the microscopes can see smaller things faster. The thing about the phones getting smaller i feel that the phones are getting bigger. If you haven't seen the I PhoneX then you doen't know that phones are getting bigger.did you know that seth dobson is the younger brother of Rebecca dobson? coconuts i just remembered that you knew that. coconuts!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
