KNbO3 (KN) with a perovskite structure is an outstanding representative of lead-free piezoelectric materials, and its mesocrystals have broad application prospects in the fields catalysis, energy storage, conversion. However, formation conditions KN reported so far are difficult owing to their high aspect ratio excellent preferred orientation. In this study, solvothermal process was used successfully prepare flake-like potassium salt Lindquist hexaniobate (K8Nb6O19·10H2O). Subsequently,...
Nitrogen is a rare dopant that can not only enter the interstitial sites (Ni) but also oxygen substitutional (Ns) of vanadium dioxide (VO2). The incorporation N atom has been demonstrated to modulate phase transition behavior VO2. However, deep understanding effect doping on and thermochromic properties VO2 remains lacking. Here, we prepare N-doped with tunable sites. Ni demonstrates ability slightly increase transformation temperature (Tc), while greatly improving visible light...
The anomalous gas sensing behavior has garnered significant attention from researchers, prompting a re-evaluation of the theory. This work focuses on inversion induced by element doping. W/Mo/Cr-doped VO2(M1) samples are synthesized, and their behaviors investigated. results show that elements can modulate with an opposite orientation. in orientation is attributed to extent reduced Fermi level after W-doped maintains resistance-decreased (-n). In contrast, decrease formation Schottky barrier...
The development of a flexible wearable piezoelectric power device has recently caught extensive attention, especially in making inorganic ceramics into polymers from composite with excellent response. As fillers, an oriented polycrystal can improve the mechanical energy efficiency nanogenerators. Herein, two-dimensional BaTiO3-oriented polycrystals are prepared via two-step hydrothermal process based on topochemical conversion mechanism. Additionally, high-performance nanogenerator was...
A high-performance, degradable flexible PNG for human motion status monitoring was manufactured from 2D plate-like BT embedded in PLA, where the high output voltage of realised by mechanical impact deformation.
Nonmetal elements have remarkable potential in modulating the metal–insulator transition behavior of VO2, but little is known about their impact on thermochromic performance. Here, phosphorus (P) successfully doped into VO2 by precursor decomposition diffusion. XPS spectra, together with DFT calculations, demonstrate V-substitutional doping (Pv). The onset temperature P-doped decreases from 62.8 to 50.2 °C. Theoretical calculations reveal that PV interferes strong V–V interactions,...

As a typical cation-exchangeable layered compound, titanate has unique open structure. Its excellent physical and chemical properties allow its wide use in the energy, environmental protection, electronics, biology, other fields. This paper reviews recent progress research on structure, synthesis, properties, application of titanates. Various reactivities, as well advantages disadvantages, different synthetic methods are discussed. The reaction mechanism influencing factors ion exchange...
Abstract Traditional selectivity of gas sensors determined by the magnitude response value has significant limitations. The distinctive inversion sensing behavior not only defies traditional theory but also provides insight into defining selectivity. Herein, novel definition is established in a study with VO 2 (M1).

Interestingly, obtained polycrystalline BT constructed from oriented nanoparticles shows set of single-crystalline diffraction points, implying that is mesocrystal. The [010] and [001] directions mesocrystalline correspond to original HTO crystal, respectively,...
Reactions of the early transition metal atoms Sc, Ti, and V with NH3 molecules in solid argon matrix have been studied by infrared spectroscopy density functional calculations. It is found that ground-state reacted to form MNH3 (M = V) complexes spontaneously on annealing. The underwent photochemical rearrangement HMNH2 molecules.
