Scientists have discovered that treating graphene nanofoam electrodes with hydrogen can actually increase the capacity and transport speed of Li-ion batteries. In recent years, graphene has been ...

However, the researchers also found that the hydrogen battery demonstrates a longer lifespan, enduring 18% more charge-discharge cycles than the lithium-ion battery. “This makes the hydrogen ...

Therefore, we have now developed and demonstrated nondestructive state detection and measurement techniques on a single molecular hydrogen ion (HD +) in a Penning trap; applicable to other ...

All acidic aqueous solutions contain protonated water, known commonly as the hydronium ion (H 3 O +). Brønsted acids release one or more of their protons (hydrogen ions), which ... resulting in a net ...

The H scale-H being the symbol for the logarithm of the reciprocal of the hydrogen ion concentration-may seem at first a little topsy turvy, inasmuch as the variable studied-the hydrogen ion ...

At a pH of 1, the hydrogen ion concentration is 10 times higher than that at 2. The pH is thus expressed as pH = log 1/[H+] = −log [H+]. The square bracket is a symbol of the concentration of ...
