  1. High nitrogen martensitic stainless steels show improved resistance to localized pitting. Corrosion & Resistance of Stainless steel : https://en.wikipedia.org/wiki/Stainless_steel#Corrosion_resistance
  2. The cleaning begins with a natural chemical reaction called oxidation-reduction discovered by a Dutch gardener. He used his steel planting tool to remove the stubborn leek odors from his hands. When in contact with water, the metal ions in stainless steel capture and penetrate the sulfur and nitrogen molecules responsible for the foul fumes. So, on first contact with steel, the smell of foods rich in sulfur disappears immediately. An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
  3. Yes sorry. Finally I know. I thought you were talking about a specific detail for the weak interaction with dark matter. Yes.
  4. No. Not really. I have my little idea. But I think that will interest no one. Besides, why to put this thread in speculation? Thank you for your answers.
  5. Which means that thanks to the strong interaction, we could explain why dark matter is dark? By what approach or reason do we make this deduction? Is it related to the very weak interaction that can occur? The mass, and the interaction. The ideal would be to find an axion of a large mass which does not interact at all with baryonic matter. That's it ? Quite the contrary. Are you wondering why dark matter does not interact with baryonic matter?
  6. Thank you strange. But what is the link (if there is one) between dark matter and QCD?
  7. A physicist told me this was wrong. What is the relationship between a dark matter axion and the QCD axion? Or quite simply what about the history of the dark matter in the functioning of the QCD? Thank you.
  8. Here is what I had already written about it. Catch me if i'm wrong: The difficulty of QCD lies in the interpretation of the SU(3) symmetry due to the convergence of the baryonic flow in relation to the coupling constant. The role of dark matter in the case of QCD is found in the mass of the axion which is very often taken into account for example very early in the creation of the universe by particle exchange WIMPs. If I have understood rightly, an outcome could be determined in the relic density in the supersymmetry particles like the neutralino. The SUSY is only an illusion insofar as the exchange of the flow can only be in a dynamic of oscillation alternating between its two potentials (DM-SM).
  9. There is an unusual term called "QCD axion dark matter". Do you have any idea what "QCD axion dark matter" is? Here are among others the most recent documents on this subject: https://arxiv.org/abs/1910.04163 QCD Axion Dark Matter from a Late Time Phase Transition https://arxiv.org/abs/1905.04686 A Unique Multi-Messenger Signal of QCD Axion Dark Matter https://arxiv.org/abs/1901.07401 A new experimental approach to probe QCD axion dark matter in the mass range above 40μμeV https://arxiv.org/abs/1711.10486 QCD Axion Dark Matter with a Small Decay Constant
  10. It comes from the work of a researcher. Even beginners like me. Is math compulsory? It was my question. It was because more younger I had to write oscillator 1001 times, before understanding that it took two l.
  11. I want to make the link between a harmonic oscillator, and the functioning of the universe. Here, graphically speaking, this is how would be the evolution of the universe following the rules of the potential energy of a harmonic oscillator: What do you think of this evolution? Reference: [1] The Universe as an Oscillator https://arxiv.org/abs/1807.03864
  12. The formula of QCD does not change. So dark matter can be explained by the quantum vacuum of quantum chromodynamics. The pressure? Yes it is rather the reverse. What is the difference between: and: Case for axion origin of dark matter gains traction ?
  13. Here is an approach by the Cosmological Constant https://arxiv.org/abs/1802.08317 With the Oscillator:
