Many industrial processes, including those producing aluminum and “green” hydrogen, use electrodes to speed up chemical reactions. Unfortunately, bubbles that form on the electrode reduce its efficiency anywhere from 10 to 25 percent by blocking parts of the electrode. The assumption has been that any area shadowed by bubbles is blocked, but a recent study shows that’s not the case. Instead, it’s only the electrode area in direct contact with the bubble that’s blocked.
To show this, researchers looked at a smooth electrode where bubbles formed randomly (left) and a nanotextured one with many spots where bubbles could form (right). In the animation above, bubble shadows are highlighted with circles. There are clearly more bubbles on the nanotextured electrode, but it actually performs better than the smooth electrode because the bubble contact area is smaller. (Image and research credit: J.

So many natural processes take place right in front of us, but they’re too small and too fast to see. Here, the Beauty of Science team puts some of those processes — crystallizing solids, nucleating bubbles, and more — front and center. The shapes and colors draw you in, inviting you to engage with science we see daily but rarely appreciate. (Video and image credit: Beauty of Science)

@Wolfie_Rankin this is why you don't clean your cups *too* hard.

Of course, I didn't even know then that many #snowflakes have bacteria at their centre! #Ice formation requires #nucleation, and #bacteria are everywhere...
I'm the leader of the #metamorphic #petrology group https://www.teamgar.net/. Using X-rays, electron- and ion-beams, and lasers, we study the chemical and isotopic properties of #crystals and their 3D distributions in #geological #materials. This helps us to better understand #nucleation, #growth and #diffusion. We collect our samples in the field and develop numerical models that simulate geological processes. The software https://www.teamgar.net/theria_g is a product of that research.
