Historically, the addition of two Windows keys and a menu key marked the change from the 101/102-key to 104/105-key layout for PC keyboards. [2] Compared to the former layout, a Windows key was placed between the left Ctrl and the left Alt and another Windows key and the menu key were placed between the right Alt (or AltGr) and the right Ctrl key.
In computing, the menu key (≣ Menu), or application key, is a key with the primary function to launch a context menu with the keyboard rather than with the usual right-mouse button. [1] It was previously found on Microsoft Windows-oriented computer keyboards and was introduced at the same time as the Windows logo key.
In computing, a button (sometimes known as a command button or push button) is a graphical control element that provides the user a simple way to trigger an event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action.
Windows 8.1 and Windows Server 2012 R2 restore the button back to its original place without removing the new button in the charms. [21] [22] On most versions of Windows, the Start button is located on the lower left corner of the screen, while the start button on Windows 11 is located in the center (but can be moved back to the lower left corner).
The first sodium-ion cell using hard carbon was demonstrated in 2003 and showed a 3.7 V average voltage during discharge. [20] Hard carbon was the preferred choice of Faradion due to its excellent combination of capacity, (lower) working potentials, and cycling stability. [ 21 ]

Voltage-gated calcium channels (VGCCs), also known as voltage-dependent calcium channels (VDCCs), are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g. muscle, glial cells, neurons) with a permeability to the calcium ion Ca 2+.
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
