Acoustic shock wave from spark?

I'm working with an application where I'd like to detect a short sound from a distance up to 100 m. An ultrasonic chirp has been unreliable so far. I was contemplating the use of the snap of an...

What is the best format to export from igraph to gephi?

I have been using R, igraph, and gephi to create semantic networks. I generally export gml file from R through igraph, then import the gml file into gephi for further adjustment. However, I am now...

Can we relate DC measured resistance to the resistance fitted by equivalent circuit from AC Nyquist plot?

My fitted resistance results from Nyquist are not equal to the one measured from the DC signal. Wondering if it is fair to compare these values measured in different ways.

How to distinguish between A.C and D.C Josephson Effect ?

When two superconducting materials are separated by an insulator of very few thickness and are connected by a wire, a dc current flows in the external circuit (dc.Josephson effect). However, if...

Are. or are not, superinsulators with respect to electricity also superinsulators with respect to heat?

Superconductors with respect to electricity manifest zero resistance to electric current. But they are NOT also superconductors with respect to heat. The flip side of electrical superconductivity...

Anyone know where to find BSCCO .cif files?

I've been looking for a .cif file for the superconducting phases of BSCCO(2201), BSCCO(2212), and BSCCO(2223). I know they are tetragonal crystals, but every file I find seems to fit it to an...

Is superconductivity an Equilibrium or Non-equilibrium phenomenon?

Many researchers consider superconductivity (SC) an equilibrium phenomenon, because there is no external acting force (zero resistivity) and only temperature change is sufficient to make the phase...

How to remove the papers I'm not entitled to have, by mistake?

I don't know by whose fault, I was claimed one of the authors of many papers I'm not entitled to have. I don't know how to remove those papers either. For example, how on earth do I have papers...

Need oxide thin films for your research?

We have built a high throughput PLD machine, rather than making the usual 2-5 films a day we can make around 20-40 films a day depending on the substrates size and we love it. We want to know if...

Twisted bilayer Graphene shows superconductivity. Do the pi- electrons moving between the two layers form cooper pair or is it in other way around?

stacking one layer on another monolayer of graphene in a 'magic angle' changes the properties of the bilayer significantly. Which phenomenon will be responsible for the superconductivity. I...
