vanadium air classifiers

Identify different classes of classifiers

Body part classifier (BPCL) is a symbol that refers to a part of the body beyond the frame of signing area -- e.g. legs, back, feet, etc. For example, you utter the ASL word #foot and then use its classifier (e.g. the passive hand) to represent the foot. For a brain or a heart, you use the classifier in the mid-air space. Plural classifier (PCL)

Vanadium redox battery - Wikipedia

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery that employs vanadium ions in different oxidation states to store chemical potential energy.

"Classifiers" American Sign Language (ASL)

A classifier (in ASL) is a sign that represents a general category of things, shapes, or sizes. A predicate is the part of a sentence that modifies (says something about or describes) the topic of the sentence or some other noun or noun phrase in the sentence. (Valli & Lucas, 2000) Example: JOHN HANDSOME.
