Evidence for the formation of a Mott state in potassium-intercalated pentacene [PDF]
Phys. Rev. B. 79, 125116 (2009), 2008 We investigate electronic transport through pentacene thin-films intercalated with potassium. From temperature-dependent conductivity measurements we find that potassium-intercalated pentacene shows metallic behavior in a broad range of potassium concentrations.

Evidence for phase formation in potassium intercalated 1,2;8,9-dibenzopentacene [PDF]
Eur. Phys. J. B 85, 242 (2012), 2012 We have prepared potassium intercalated 1,2;8,9-dibenzopentacene films under vacuum conditions. The evolution of the electronic excitation spectra upon potassium addition as measured using electron energy-loss spectroscopy clearly indicate the formation of particular doped phases with compositions K$_x$dibenzopentacene ($x$ = 1,2,3).

Potassium Effects on NCC Are Attenuated during Inhibition of Cullin E3–Ubiquitin Ligases
Cells, 2021 The thiazide-sensitive sodium chloride cotransporter (NCC) plays a vital role in maintaining sodium (Na+) and potassium (K+) homeostasis. NCC activity is modulated by with-no-lysine kinases 1 and 4 (WNK1 and WNK4), the abundance of which is controlled by

Negative-charge-storing mechanism of potassium-ion electrets used for vibration-powered generators: Microscopic study of a-SiO2 with and without potassium atoms [PDF]
Appl. Phys. Lett. 117, 193902 (2020), 2020 A potassium-ion electret, which is a key element of vibration-powered microelectromechanical generators, can store negative charge almost permanently. However, the mechanism by which this negative charge is stored is still unclear. We theoretically study the atomic and electronic structures of amorphous silica (a-SiO2) with and without potassium atoms ...
