What’s next? We’d like to know exactly what chemicals lead to what color. If we can develop a relationship between the energy, the oxide layers formed, & the final color, we could save lots of time by calculating the parameters for a color instead of relying on trial & error as is currently standard

How do know this reaction is happening? We bounced X-rays off the laser-exposed areas & measured the Binding Energy of electrons shooting off from the metal surface to tell us which elements & oxidation state are present on the surface, which can distinguish between Cr(OH)3 & Cr2O3

So what’s happening? Turns out there’s a whole field of engineering called “laser color marking.” Brilliant marks on metals can be produced for product identification with high-power, pulsed lasers. Compounds like chromium oxide can have bright, striking colors like this green powder

We did a few experiments and realized the glowing spots only appeared where we shined the laser and only when we applied a voltage to the metal

Our 🔬also allowed us to predict what would happen with way less materials & time. It was critical to use the same exact materials, as the trends strikingly similar between 🔬& commercial methods. I’ve worked in this field for 15 yrs & it’s the first time I’ve ever seen this good of agreement! 6/11

Why were the pores working as intended? Well, after screening many variables, we found that there was too much polymer that was used to make these materials, that would block the pores. We could “clear the way” by using solvent that dissolved some, but not all of the polymer. 5/11

The inaccessible pores weren’t apparent when we used the “conventional” methods (dry or low T). Those showed everything was good. It was only with our microscope that images in solution with similar conditions that industry would perform the separation that we saw this unexpected behavior. 4/11

This literally challenges what textbooks show. It is surprising since the materials are sold with 100 nm pores and we were looking at a 0.7 nm molecule – this would be like a tennis ball not passing through something with the diameter of a jet engine. 3/11

Solid materials that are used to separate a desired molecule from a liquid mixture have high porosity to increase surface area. We made a surprising observation when we imaged these on our fluorescence microscope: materials that are sold as “fully porous” were not really that porous! 2/11

Single molecule microscopy of protein electrophoresis! Start of the video shows Brownian motion, then voltage applied when you start seeing everything move to the right of the frame! Data from lab member Charlotte in collaboration w/ @uagurkan.bsky.social . 🔬

I guess this is what Amazon thinks is the relevant fashion pick for a physicist?
