How we can determine LoD of a voltametric sensor?

many answers are available here, which says the standard deviation of the blank should be taken for the calculation. But my doubt is how we can find out the standard deviation of the blank if we...

WHY a composite material with conductivity as high as 10-4 S/cm shows high dielectric constant ( real part of permittivity as high as 6K) ?

I have done the dielectric measurement of conducting polymer nanocomposites containing some metal sulphide as nanofiller. And its d.c conductivity was in the range of 5-100 S/cm. when I measured...

How do I calculate cysttalite size of layered fillers (hexagonal ) by using scherrer equation? is there any relation between its layer thickness?

I have incorporated layered fillers ( hexagonal crystal structure) into the conjugated polymer matrix. I would like to calculate the crystallite size of these filler particles. How we can apply...

Why Austenite grains in steel show much more twinning than ferrite grains?

It is oftentimes said to be a distinctive metallographic trait that differentiates a fully austenitic and a fully felly ferritic steel without etching that might distinguish between two. Why...

Discrete Phase model (DPM) particle break-up has particle size limits during particle tracking?

Hello, I am currently working on simulating water droplet partciles in a closed room. When I use uniform particles, without "particle break-up", I can carry out the simulation without any problem....

What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...

What is the most suitable server for predicting protein structures in bacteria?

I have used the i-Tasser several times, however it has been unavailable for several days. I tried the swiss-model, but the output was not very pleasant due to the model used. Is there any other...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
