What is the best substrate for exfoliating few layers of hexagonal boron nitride (hBN) using traditional scotch tape method?

Unlike graphene, it is usually very difficult to exfoliate few layers (~10 nm thick) of hBN on SiO2 substrate due to lip-lip interaction at the edges. Au substrates have been proven very useful...

Do the introduced salts (NaOH/ HCl) influence the spectroscopic shifts of the fluorescence excitation-emission matrix?

During the resin (XAD-8) fractionation of wastewater salts (NaOH or HaCl) are used for acid or base elutions/pH adjustments. Since the amount of introduced salt is minimal, so is it required to...

What do I do with DLS peaks that are from the buffer?

I'm looking at the aggregation of my protein sample using DLS. Unfortunately, my buffer (20mM HEPES) also results in a set of peaks. These are at approximately 1 and 1000 d.nm. The lowest peak...

FLIM Signal to noise ratio of a time series - can I use dark frames to measure noise?

I am doing an analysis on some FLIM data in the form of time series image stacks. I need their signal-to-noise ratio. Recording starts several picoseconds before the excitation pulse, so no sample...

Dear Nuha, what is really your question? Is that reducing the cabin noise emission of regional aircrafts (Turboprops? Jets?) for the passenger's comfort inside the plane? Or the plane's radiated noise footprint on ground? Specifically at take-off and landing? And does your question address technologies only, or regulatory issues? Or both? You have to be specific to get relevant responses...
