Abstract:
Polarization-sensitive photodetectors, based on anisotropic semiconductors, have exhibited wide advantages in specialized applications, such as astronomy, remote sensing, and polarization-division multiplexing. For the active layer of polarization-sensitive photodetectors, recent researches focus on two-dimensional (2D) organic-inorganic hybrid perovskites, where inorganic slabs ....

Polarization-sensitive photodetectors, based on anisotropic semiconductors, have exhibited wide advantages in specialized applications, such as astronomy, remote sensing, and polarization-division multiplexing. For the active layer of polarization-sensitive photodetectors, recent researches focus on two-dimensional (2D) organic-inorganic hybrid perovskites, where inorganic slabs and organic spacers are alternatively arranged in parallel layered structures. Compared with inorganic 2D materials, importantly, the solution accessibility of hybrid perovskites makes it possible to obtain their large crystals at low cost, offering exciting opportunities to incorpora ....

Emissive supramolecular metallacages via coordination-driven self-assembly

Credit: @Science China Press
Metallacages prepared via coordination-driven self-assembly have received extensive attention because of their three-dimensional layout and cavity-cored nature. The construction of light-emitting materials employing metallacages as a platform has also gained significant interest due to their good modularity in photophysical properties, which bring emerging applications in fields as diverse as sensing, biomedicine, and catalysis.
However, the luminescence efficiency of conventional luminophores significantly decreases in the aggregate state because they encounter unfavorable aggregation-caused quenching (ACQ). Therefore, it was quite a challenge to fabricate light-emitting metallacages with high luminescence efficiency in various physical states.
In 2001, Tang s group discovered aggregation-induced emission (AIE) phenomenon that some nonluminous or weakly emissive materials in molecular state are highly emissive in aggregate state. The unde ....

The diesel engine is the backbone of transportation due to its irreplaceability as the primary power source for the freight, navigation and marine engine industries and non-road engineering machinery for the foreseeable future. However, the control of contaminants from fuel combustion has become an urgent global concern. Nitrogen oxides are the primary pollutants from transportation and can contribute to the formation of haze, photochemical smog and acid rain. Selective catalytic reduction of NOx with ammonia (NH3-SCR) technology has been successfully and commercially applied for controlling pollution from diesel vehicle exhaust. The development of efficient and stable NH3-SCR catalysts has been pu ....
