How to build my own lab made four point probe set up?

Hello, I'm trying to measure the conductivity of semiconductor films but since I don't have a commercial four point probe set up I would like to build one on my own in my lab. I have generators,...

Does anybody know why my chitosan/pva/gelatin hydrogel dissolve in PBS?

My final research is about making chitosan/pva hydrogel for wound healing using gelatin as crosslinker. Last month, i made the thin film hydrogel and it turn well. It was okay. Last week, i make...

Is it possible to manufacture polypropylene sheets using a biaxial process?

I know that films and other low-thickness laminated products are produced using biaxial orientation, but is there something similar for sheets with a thickness of around 6 mm? Or are they...

How do you decide an optimal AC amplitude for non-faradaic electrochemical impedance spectroscopy?

I work with planar interdigitated electrodes (IDEs). The finger width and the spacing between the fingers are 5 micron. The surface of the IDEs is coated by a non-conductive polymer layer...

Why am I seeing only one initial maximum in torque-time curves for the fusion of PVC in a Brabender?

We're studying the stability and fusion behavior of multiple PVC compounds in a Brabender. After a few trials, we set the temperature at 195 °C and the rotor speed at 70 rpm. Samples differ in...

What is the thickness of your samples...

Subash C K

Thank u for your reply...... it is a polymer thin film... i can coat it in different substrates... thickness will be 300 nm to 1 microns...

You have to do PFM for this. We have piezo measurement unit but it work for bulk samples only.

thank you.... what is the minimum thickness for measuring piezo response in your facility?

The basic thing is, we can measure stand alone film. But we don't have facility for measuring piezo constant with substrate. So, 100 micron would be measurable in our sample holder.

Thank you.....
