AI Thread Summary
Polycarbonate is an excellent choice for applications requiring transparency and high fracture toughness, making it suitable for projects like a CD case. It is known for its superior impact resistance compared to polystyrene, which aligns with the project's requirements for better fracture toughness. While specific fracture toughness values may be challenging to find, polycarbonate is widely recognized for its durability and shatter resistance, often recommended for safety applications such as children's eyewear. This material also typically falls within a cost range that is acceptable compared to polystyrene, making it a viable option for the project.

Polycarbonate fracture toughness?

I am doing a project in which I have to make a cd case out of a material which is transparent, has a young's modulus not too different to polystyrene, can't cost more than twice polystyrene and has a fracture toughness better than polystyrene!

Polycarbonate looks good so far but I can't find the fracture toughness of it anywhere.

Please Help...
It's due tomorrow!

Thanks!

Polycarbonate is highly resistant to fracture, which is why I always recommended it for kids' lenses. You can find shatter-resistance information if you look around.
 

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...
