  2. Splint (laboratory equipment) - Wikipedia

    en.wikipedia.org/wiki/Splint_(laboratory_equipment)

    The glowing splint test is a test for an oxidising gas, such as oxygen. [4] In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel. [4]

  3. Nickel–hydrogen battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–hydrogen_battery

    A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]

    [specify] [2] [3] A glowing splint can be used to show that the gas produced is oxygen. [9] The rate of foam formation measured in volume per time unit has a positive correlation with the peroxide concentration (v/V%), which means that more foam will be generated per unit time when a more concentrated peroxide solution is used.

    en.wikipedia.org/wiki/List_of_battery_types

    This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.

  6. Hydrogen battery - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_battery

    Hydrogen battery may refer to: Nickel–hydrogen battery , a rechargeable battery with a power source based on nickel and hydrogen Hydrogen fuel cell , an electrochemical cell that uses hydrogen as a fuel source

  7. pH meter - Wikipedia

    en.wikipedia.org/wiki/PH_meter

    The glass electrode for measuring the pH has a glass bulb specifically designed to be selective to hydrogen-ion concentration. On immersion in the solution to be tested, hydrogen ions in the test solution exchange for other positively charged ions on the glass bulb, creating an electrochemical potential across the bulb.

  8. Tritium radioluminescence - Wikipedia

    en.wikipedia.org/wiki/Tritium_radioluminescence

    Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence .

  9. Voltage-gated proton channel - Wikipedia

    en.wikipedia.org/wiki/Voltage-gated_proton_channel

    As a result, the opening of voltage-gated hydrogen channels usually hyperpolarize the cell membrane, or makes the membrane potential more negative. [10] A recent discovery has shown that the voltage-gated proton channel Hv1 is highly expressed in human breast tumor tissues that are metastatic, but not in non-metastatic breast cancer tissues. [11]
