Are there any known ways to differentiate between isotopes visually via emissive behaviour?

Lets say we have a luminescent molecule which is highly sensitive to protonation in specific solvents. If adding a) AcOH and b) deuterated AcOH to 2 aliquats of the same solution a results in...

What is the correct way to prepare a solid state sample for QY measurement?

We approach this problem purely from the sample side and disregard the specific apparatus. Non the less of course an integrating sphere with reabsorbtion correction will be used. Lets say we want...

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...

Why sometimes current- voltage plot in chemiresistors/ FET does not pass through the origin?

I am trying to measure resistance from I-V curve from a chemiresistor/ FET sensor with a keithly sourcemeter. The substrate is soaked/ wet with protein and phosphate buffer only. But the I-V line...

MOS Capacitor instance or a mosfet used as a cap (D-S-B connected to gnd)?

Hi, in Cadence Spectre simulations should I use a MOS cap instance or a mosfet (D-S-B connected to gnd) to simulate a real life MOS-cap? I tried both of them and they gave different results i.e....
