Capacitative Calcium Entry [PDF]

open access: yesPhysiology, 1998
Capacitative Ca2+ entry is a recently discovered Ca2+ entry pathway that is activated on depletion of intracellular Ca2+ stores, providing an avenue for store refilling. Despite recent progress in elucidating the capacitative Ca2+ entry pathway, the mysteries of its molecular identity, its biophysical properties, and the store depletion signal remain.

Anomalously large capacitance of a plane capacitor with a two-dimensional electron gas

open access: yes, 2012
In electronic devices where a two-dimensional electron gas (2DEG) comprises one or both sides of a plane capacitor, the resulting capacitance $C$ can be larger than the "geometric capacitance" $C_g$ determined by the physical separation $d$ between ...

The effect of electron dielectric response on the quantum capacitance of graphene in a strong magnetic field

open access: yes, 2013
The quantum capacitance of graphene can be negative when the graphene is placed in a strong magnetic field, which is a clear experimental signature of positional correlations between electrons.
