Summary: The preparation of hollow Cu2MoS4/ZnIn2S4 heterostructural nanocubes with intimate-contact interface via a self-template way has significantly improved photocatalytic efficiency. The study shows that the enhanced photocatalytic performance is mainly attributed to the abundant active sites and increased light absorption provided by the hollow structure, as well as the built-in electric field facilitating charge separation.

Summary: In this study, hollow SnO2/CdS QDs/CdCO3 heterostructured nanocubes were synthesized and used to construct a sandwich-typed photoelectrochemical (PEC) immunosensor for the detection of CYFRA 21-1. The PEC responses were amplified by the in-situ catalytic precipitation catalyzed by PtPd/MnCo-CeO2 nanozyme. The biosensor showed a wide linear range and a low limit of detection, making it suitable for detecting cancer biomarkers in clinic.

Summary: In this work, hierarchically hollow CoFe2O4/polypyrrole nanocubes with enhanced electromagnetic characteristics for MW absorption were fabricated. The electromagnetic characteristics can be adjusted by regulating the proportion of polypyrrole. The outcomes demonstrate that the as-prepared composites have outstanding MW absorbing ability and are expected to be potential MW absorbers for extensive applications.

Summary: Colloidal particles can self-organize into highly ordered superstructures, and in this study, uniform polystyrene particles were prepared and used to fabricate solid and hollow colloidosomes. By varying parameters such as shaking frequency and solvent ratio, the size and morphology of the colloidosomes could be controlled, with the formation mechanism well interpreted based on adsorption energy.

Summary: Novel synthesis techniques were employed to fabricate SiO2@SnO2 core-shell microbelts and hollow SnO2 microbelts, which were sensitized with platinum nanoparticles to enhance their acetone detection capability. The sensitized SnO2 microbelts showed significantly higher response to 2 ppm acetone and faster response time compared to pristine SnO2 microbelts. The sensor based on sensitized SnO2 microbelts also exhibited promising stability and repeatability toward acetone exposure in a humid environment.
