Electric field induced antiferroelectric-ferroelectric phase transition is a double-edged sword for energy storage properties, which not only offers a congenital superiority with substantial energy storage density but also poses significant challenges such as large polarization hysteresis and poor efficiency, deteriorating the operation and service life of capacitors. Here, entropy increase effect is utilized to simultaneously break the long-range antiferroelectric order and locally adjust the fourfold commensurate modulated polarization configuration, leading to a breakthrough in the trade-off between recoverable energy storge density (14.8 J cm) and efficiency (90.

The space charge effect induced by high-quality heterojunctions is essential for efficient electrocatalytic processes. Herein, we delicately manipulate intermolecular charge transfer by modifying substituents (-g = -CH3, -H, -NO2) with various electron donating/withdrawing capabilities in CoPc-g/CoS organic-inorganic heterostructures. CoPc-CH3, as a typical electron donor, transfers more electrons to CoS due to the presence of -CH3, forming the strongest space electric field and thus regulating the dual active sites at the interface.

Altering the electron distribution within a catalyst to manipulate internal charge migration pathways is an effective strategy for achieving high efficiency in carrier separation and migration, which is essential for the advancement of photocatalytic water oxidation technologies. We have employed atomic layer deposition (ALD) to construct a BiFeO/CuO (BFO/CuO) heterojunction with a specific CuO thickness, resulting in a Z-type junction (BFO/CuO50) characterized by a robust internal electric field. This junction facilitates the spatial separation of charge carriers, thereby enhancing their migration efficiency.

A carbon nanotube (CNT) composite is an effective method to improve the thermoelectricity of materials. However, the depletion layer between the CNT and thermoelectric (TE) material always decreases the contribution of CNT to the conductivity of the TE material. It is important to eliminate the depletion layer for improving the TE properties.

Rotational spectroscopy is an excellent tool for structure determination, which can provide additional insights into local electronic structure by investigating the hyperfine pattern due to nuclear quadrupole coupling. Jet-cooled molecules are good experimental benchmark targets for electronic structure calculations, as they are free of environmental effects. We report the rotational spectra of 2-chlorobenzaldehyde, 3-chlorobenzaldehyde, and 4-chlorobenzaldehyde, including a complete experimental description of the nuclear quadrupole coupling constants, which were previously not experimentally determined.
