Proton insertion/extractionManganese dioxide(MnO_(2)) is considered as a potential cathode material for aqueous magnesium-ion batteries. However, the charge/discharge mechanism of MnO_(2)in aqueous electrolyte is still unclear. In present study, highly porous 未-MnO_(2) is investigated, which ...
Ammonium (NH4+) is a positively charged ion (or cation) that is formed by the addition of a hydrogen proton to ammonia (NH3). Ammonia is found naturally in water, but if it is found at higher than natural levels this is a sign of contamination. This is why it’s so important to ...

The mass spectrometer was operated in positive ion mode. MS/MS spectra were acquired with either higher-energy collisional dissociation (HCD) in Orbitrap (Q-Exactive) or collision-induced dissociation (CID) in ion trap (Fusion Lumos). The spectra labeling, database search, and quantification were...
Plant survival requires an ability to adapt to differing concentrations of nutrient and toxic soil ions, yet ion sensors and associated signaling pathways are mostly unknown. Aluminum (Al) ions are highly phytotoxic, and cause severe crop yield loss and

the Ion P1 sequencing Kit v2 (Thermo Fisher Scientific) on an Ion Proton™ sequencer, following Manufacturer’s instructions. Samples were run on two Ion P1 Chip Kit v3 chips (Thermo Fisher Scientific). All the libraries were sequenced in both chips to prevent the influence of batch effects...
The liquid chromatography was coupled to an EVOQ Elite TripleQuad mass spectrometer (Bruker) equipped with an electrospray ion source operated in combined positive and negative ionization mode. The instrument parameters were optimized by infusion experiments with pure standards. The ion spray voltage ...
