    en.wikipedia.org/wiki/Standard_electrode...

    Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and Absolute partial pressure 101.325 kPa (1.00000 atm; 1.01325 bar) for each gaseous reagent — the convention in most literature data but not the current standard state (100 kPa).

  3. Reference electrode - Wikipedia

    en.wikipedia.org/wiki/Reference_electrode

    To focus on the reaction at the working electrode, the reference electrode is standardized with constant (buffered or saturated) concentrations of each participant of the redox reaction. [1] There are many ways reference electrodes are used. The simplest is when the reference electrode is used as a half-cell to build an electrochemical cell.

  4. Graphene - Wikipedia

    en.wikipedia.org/wiki/Graphene

    Graphene is the strongest material ever tested, [7] [8] with an intrinsic tensile strength of 130 GPa (19,000,000 psi) (with representative engineering tensile strength ~50-60 GPa for stretching large-area freestanding graphene) and a Young's modulus (stiffness) close to 1 TPa (150,000,000 psi).

    1.15: 28: 1.251 – – not Often used at high pressure. Does not facilitate combustion. Can be used with 10–20% of SF 6 as a lower-cost alternative to SF 6. Can be used standalone or in combination with CO 2. Non-electron attaching, efficient in slowing electrons. Air: 29/mixture 1: 1.2 – – Breakdown voltage 30 kV/cm at 1 atm. Very well ...

  6. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
