Abstract Background Humic substances can be considered as polyelectrolytes with supramolecular character and complicated behaviour in water environment. The fractions of humic dissolved are the most active ones determinative for their functioning nature, where proton-binding dissociation ability play a crucial role. fulvic acids affected by different circumstances including concentration which ...

Single crystal Li[Ni 0.5 Mn 0.3 Co 0.2 ]O 2 //graphite (NMC532) pouch cells with only sufficient graphite for operation to 3.80 V (rather than ≥4.2 V) were cycled charging either 3.65 or facilitate comparison LiFePO 4 (LFP) on the grounds of similar maximum potential and negative electrode utilization. The NMC532 cells, when constructed be charged V, have an energy density that exceeds LFP a cy...

In the present paper we report on an analysis of the fine structure of the first excited quartet T2g of Mn4+ ions which occupy the octahedral site in the Cs2GeF6 host crystal. The dynamic T2g⊗ (eg + t2g) Jahn–Teller effect is considered in details, including the Ham effect of the reduction of the spin-orbit splitting and displacements of the ligands due to the combined effect of the a1g and eg ...

The cumulative reaction probability is calculated for the H,+OH+H+H,O reaction in its full (six) dimensionality for total angular momentum J=O. The calculation, which should give the (numerically) exact result for the assumed potential energy surface, yields the cumulative reaction probability directly, without having to solve the complete state-to-state reactive scattering problem. Higher angu...
