Magnetic PDMS micro-pillars
If | we mange to create PDMS molds outside of the clean room |
|---|---|
Then | it will reduce the need for clean room |
But | it might lower the device quality |
creating one device takes long time
create copies from a working device and not from scratch
creating one mold takes long time in the clean room
new process without the need of clean room
the lithography process is to long
we need to improve the process or find a way to skip it
we need to expose a lot of area to create the holes
we need to change the pattern to make the process faster
we can't create multiple devices at the same time to reduce time
we need to create from one mold multiple molds to do it we can create silicon mold of pillars and then to create multiple holes molds from PDMS instead of silicon.
by creating silicon pillars instead of holes - the time in the clean room is reduced significantly because the exposure area is a lot smaller

we depend to much on the skilled operator, by reducing the process that requires the skilled operator we can make the process a lot more simple

This project aims to develop an efficient and reproducible method for synthesizing perovskites from metals with halides. The focus will be on addressing material synthesis challenges, ensuring scalability from laboratory to industrial production, optimizing the physical and chemical properties, and minimizing the environmental impact.
Chilled water is used for production equipment cooling. Suddenly pH of the water started to drop. The aim of the project is to analyze the issue, understand the root cause, and propose solutions to the problem.
