Polyanionic Compounds for Potassium‐Ion Batteries
The Chemical Record, 2018AbstractLithium‐ion batteries have the highest energy density among practical secondary batteries and are widely used for electronic devices, electric vehicles, and even stationary energy‐storage systems. Along with the expansion of demand and applications, the concern about resources of lithium and cobalt is growing.

Potassium compounds for gamma spectrometer efficiency verification
Applied Radiation and Isotopes, 2017Now-a-days several standard and well calibrated radioactive sources are available for gamma spectrometer efficiency calibration but at some situations, like lack of standard calibrators, in need of verification of standards or preparation a standard with the same properties with the interested sample, 40K is a cheap and easily available radioisotope ...

Tailor-made Oligosilyl Potassium Compounds
Organometallics, 2002A number of differently substituted oligosilyl potassium compounds have been prepared by reaction of the respective trimethylsilylated precursors with potassium tert-butoxide. It has been demonstrated that in the presence of larger trialkylsilyl groups always trimethylsilyl groups are removed selectively.

Potassium-oxygen graphite intercalation compounds
Synthetic Metals, 1994Abstract Intercalation of potassium superoxide KO 2 into graphite in the presence of potassium metal was studied. Graphite intercalation compounds of stage 1 (assigned formula C 4 KO 2 , c -axis repeat distance 8.44 A) and stage 2 (assigned formula C 8 KO 2 , c -axis repeat distance 11.75 A) were synthesized and isolated for the first time.

ESR dosimetry with lithium, potassium, and sodium compounds
Applied Radiation and Isotopes, 2022This work consists of a first investigation of materials that could be used as ESR dosimeters with doses up to 5 Gy aiming possible applications that would include retrospective dosimetry or dosimetry in specific applications. The characteristics considered were radiological properties close to that of soft tissues, evaluated through their effective ...
