However, it is adversely affected by the harmful P2-O2 phase transitions which cause substantial capacity degradation and poor cycling performance. In this work, a unique P2(84%)/O3(16%) biphasic layered oxide, Na0.76Ni0.22Mg0.11Mn0.57Ti0.1O2(NNMMT), is successfully designed and synthesized by Mg/Ti co-doping strategy. The doping of Mg and Ti can form stable O-TM-O bonds, while the biphasic structure generates distinctive interlocked interfaces at the boundaries. The harmful phase transition caused by interlayer slip and structural strain is well suppressed under the synergistic effect of these two factors. As a result, NNMMT demonstrates exceptional capacity and cycling stability (reversible capacity of 109.8 mAh g-1 at 1 C and capacity retention of 97.35% after 100 cycles). Meanwhile, the higher proportion of the P2 phase enables NNMMT to maintain excellent rate capability (initial discharge capacity of 88.9 mAh g-1 at 5 C). Additionally, Ex-situ X-ray diffraction analyses before and after cycling demonstrated a significant suppression of the detrimental P2-O2 phase transition in NNMMT during the charge-discharge process, leading to a notable enhancement in structural stability.

Nevertheless, the coordinated construction of high-performance cathode and anode materials still faces challenges. In this study, sulfur-vacancy-rich CoS (V-CoS) nanoparticles were uniformly anchored onto the surface of hollow nitrogen-sulfur co-doped carbon (HNSC) spheres via a sodium borohydride-mediated chemical reduction strategy. The hollow porous architecture of HNSC and the introduction of sulfur vacancies synergistically enhance the electrochemical properties of CoS. The V-CoS/HNSC composite achieves a high specific capacity of 537.8 C g−1 at 1 A g−1 and maintains 96.3% of its capacity after 10000 cycles at 15 A g−1, showcasing excellent cycling stability. Subsequently, Fe3S4/FeS2 nanoparticles were uniformly grown on HNSC through a one-step solvothermal process.

The transverse component of the dipolar fields effectively diminishes due to the unique head-to-tail alignment of the magnetic easy axes of the Er(III) ions, leading to the emergence of open magnetic hysteresis loops at low temperatures. As the bridging atoms change from O to S and Se, a decrease of the intramolecular dipolar interactions (1.76 cm -1 (1), 1.17 cm -1 (2), 1.06 cm -1 (3)) was observed, which is accompanied by an increase of their effective energy barriers (113(3) cm -1 (1), 134(4) cm -1 (2), 141(2) cm -1 (3)).

Additionally, it demonstrates remarkable efficiency in the chemoselective hydrogenation of various nitroarenes to functionalized anilines under mild conditions (atmospheric H2 pressure, 33 ºC). Furthermore, the synergistic properties arising from the internal structure of these NPs allow them to surpass the performance of nanocatalysts made from their monometallic counterparts and simple mixtures.

The ultra-broadband emission comprises three distinct emission bands centred at 374, 515 and 620 nm, arising from Bi 3+ activators occupying Ca3, Ca2, and Ca1 sites in Ca5Ga6O14:xBi3+, respectively.

Notably, the 347 and 515 nm emissions exhibit typical thermal quenching (TQ) upon heating, whereas the 620 nm emission shows an unusual excitation wavelength-dependent transition from anti-TQ to normal TQ due to preferential energy compensation from the defect energy levels. This unique thermal response endows Ca5Ga6O14:xBi3+ with an outstanding maximum relative sensitivity of 5.12% K-1 in fluorescence intensity ratio (FIR)-based thermometry, outperforming hitherto reported single Bi3+-doped ratiometric thermometers.
