Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Improving the capacitance of supercapacitors requires gaining control over ion behavior inside carbon nanopores. This study ...

Electrical capacitance techniques offer a non‐invasive means to probe the hidden dynamics of plant root systems. Recent advances have demonstrated that carefully measured electrical properties can ...
