Hey to all..
I am in the process of designing a ligand for a clarinet mouthpiece for my own use created only out of string material (braided kevlar).
For those uninformed (like me a few weeks ago) saxophone/clarinets are instruments where the vibration of the standing wave through the...

Hello, assuming to keep an aluminum alloy motorcycle frame not in use, still, will the daily temperature variations cause thermal fatigue due to the continuous expansions and retractions or is the force developed by a few degrees of variations not sufficient to create microstructural dislocations ..read more

Yet again I have lit a scented candle in a jar and the wick disintegrates faster than the wax level decreases. Result: the candle dies after just a few percent of its material is used.
If you go into a high church, you will see great big, thick candles that burn for days and days with healthy...

I work for an aerospace supplier across different departments. I was recently shown how the production workers straighten aluminum parts after a glycol heat solutionizing process. The aluminum parts undergo a heat treatment for a few hours and are quenched in glycol.
I can't get too in-depth...

I am trying to calculate the theoretical thickness of an anodised coating. I know all values apart from I am unsure whether to use 2e or 6e for the amount of electrons.
Anode reaction as follows: 2OH = H2O + O + 2e
the aluminium reactions preferentially with the one O atom, using equation: 3O...

I want to build a mini chemical cabinet to try to eliminate odors in my garage as my wife thinks the car interior now smells. The chemical resistant rubber strip sealant is crazy expensive, but as the intended use will just be fumes with no actual chemical or fuel contact to the seals, can I use...

Not the smartest question, but why should metal deposits be put onto other metals (like razor blades) using Sputtering instead of electrodeposition or electroplating the coating onto the metal object to be coated ..read more

Hi there,
I'm working on a project where my aim is to detect the presence of PFAS (Per- and poly-fluoroalkyl substances) in air samples gathered by a system.
I've done a ton of research, but most solutions are unachievable due to price and the available space (the system should be...

Hello,
Could someone please help me understand how to approximate how long it will take for liquid nitrogen in a room temperature container to completely evaporate.
Here's the scenario:
I have a metal container (41x13x15") filled with 5.5" of liquid nitrogen (just released from a Dewar ~...
