Abstract Guest‐induced host–guest assembly in metal–organic frameworks (MOFs) has become a critical strategy to achieve circularly polarized luminescence (CPL). Herein, chiral clusters (MOCs) induced CPL of achiral MOF are reported. Enantiopure titanium‐oxo (R/S‐TOCs) effectively loaded into the pores fluorescent, highly stable NU‐901 thin film by using liquid‐phase epitaxial layer‐by‐layer encapsulation method. The resulting TOCs@NU‐901 films exhibit strong chirality, intense...

The design and development of highly efficient electrocatalysts are very important in energy storage conversion. As a kind inorganic organic hybrid material, metal-organic frameworks (MOFs) have been used as electrocatalytic reactions due to their structural diversities fascinating functionalities. Particularly, MOF thin films coordinated on substrate surfaces by liquid phase epitaxial (LPE) layer (LBL) growth method (called surface-coordinated films, SURMOFs), recently studied various...

ABSTRACT We report the evolution of X-ray pulsations EXO 2030+375 during its 2021 outburst using observations from Insight-HXMT. Based on accretion torque model, we study correlation between spin frequency derivatives and luminosity. Pulsations can be detected in energy band 1–160 keV. The pulse profile evolves significantly with luminosity outburst, leading to that whole divided into several parts different characteristics. reveals transition supercritical (fan-beam dominated) subcritical...

The fast transitions between different types of quasi-periodic oscillations (QPOs) are generally observed in black hole transient sources (BHTs). We present a detailed study on the timing and spectral properties type-B QPOs MAXI~J1348--630, by \emph{Insight}-HXMT. fractional rms variability--energy relationship energy spectra reveal that probably originate from jet precession. Compared to weak power-law dominated power spectrum, when QPO is present, corresponding spectrum shows an increase...
