AI Thread Summary

Photochromic lenses are designed to remain clear indoors and darken in response to UV light exposure outdoors. This transformation occurs due to photochromic molecules that undergo a chemical change when exposed to sunlight. The lenses provide convenience by adapting to changing light conditions, enhancing visual comfort. Resources like Transitions and Wikipedia offer detailed explanations of the technology and its applications. Understanding the science behind photochromic lenses can help users appreciate their functionality and benefits.

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
