In this study, considerable amount of O2 bubbles is generated when FP NPs are added into H2O2 solution, while H 2O2 or FP NPs solutions barely induce bubbles (Additional file 1: Fig. S9a). As a result, the tube filled with FP/H2O2 mixture shows strong dotted ech- oes ...
Moreover, such a composition yields a compound with the P2 structure considered to have better transport properties in comparison to O3 or P3 analogous [27,33]. Wang et al. [34] were the first to report that NLTO is one of a few zero-strain anode materials that exhibit negligible volume...

About 1 g of the mixture was loaded into an evacuated and sealed quartz tube and annealed under the following protocol: (i) heating to 300 °C for 12 hours; (ii) annealing at 300 °C for 24 hours; (iii) heating to the synthesis temperature Tsyn for 12 hours; (iv) ...
It has been proven that graphite can be regarded as a host for potassium ions owing to the formation of a stable intercalation compound of KC8, thus can deliver a reversible capacity of 279 mAh g−1 [3]. However, exploring and developing novel cathode materials has become the key point ...

Due to the increasing amount of lithium in the layered compound Li1+z[Mn0.4Ni0.4Co0.2]1−zO2, the average oxidation state of the transition metals has to increase to balance the whole chemical formula. This increase could be provided by either the oxidation of Ni2+ to Ni3+, or Co3+...
The mostlikely intrinsic disorder here is inferred to be near-random or only short-range ordered coexistence(mixture) of at least several (or even more) kinds of noncubic (distorted) Gd3+sites: In view of pre-dominantly P-based local structure nature of these SZs, their majorities are ...
