Is there a liquid crystal or similar material that gets cloudy when an electric field is applied, but is otherwise clear?
Is there a way to make a liquid, such as a liquid crystal material, transition from cloudy or clear and vice-versa using only electric current?
By cloudy, I mean, similar to the effect that cholesterol or 5CB exhibits, thermally.
If so, where could…

Reason behind Opaque translucent transparent
I would like to know the reason that some materials allow light to pass (transparent), blocks it a little (translucent), or completely reflects or absorbs it (opaque.)
I'm don't have a PhD, so answer this in a way that is easy to understand.

Is methanol optically active?
Strictly on theoretical basis, not based on experimental results.
I can very well be wrong, but I think that methanol should be
optically inactive because it has a plane of symmetry passing through it.
My teacher however insists that it is…

How to detect nM levels of Copper(I) Oxide in blood?
I'm trying to design an experiment to detect nM quantities of Copper(I) Oxide in fish blood. Are there any specific tests for Copper(I) Oxide that can be used to detect trace quantities(~nM)? Any non-destructive tests such as using optical methods…

optical rotation of styrene oxide
Which optical isomer of Styrene Oxide would be produced if it is synthesized via epoxidation of the halohydrin. i.e.
Is there a way to deduce this? I assume it would depend on which isomer the halohydrin itself is since that too seems to have an…

Optical activity
I was studying about the optical activity of compounds. And I found , it is written that the chirality of a molecule is the necessary and sufficient condition for a molecule to be optically active. I mean if a molecule is chiral then it ia…

Effect of optical activity
I know that optical activity means polarisation of light but what is so special in that that it changes the properties of the substances significantly

How is Volume an Extensive Property?
Based on the following definitions, can anyone explain why volume is an extensive property?
Extensive Property: Properties that depend on the amount of matter in a sample.
Volume: the amount of space an object occupies.
It has clearly been shown…

Optical activity of substituted biphenyl
How come the given compound in the diagram is optically inactive? The two rings should be in different planes due to steric hindrance between $\ce{COOH}$ and bromine. How am I wrong?
