Facile synthesis of the three-dimensional flower-like ZnFeO@MoS composite with heterogeneous interfaces as a high-efficiency absorber.

Lightweight and high-efficiency microwave absorbers are determined by structure and composition of materials. In this research, a novel core-shell ZnFeO@MoS composite with a flower-like heterostructure was synthesized successfully by a facile hydrothermal process. The unique 3D heterostructure (porous ZnFeO and MoS nanosheets as core and outer shells, respectively) endows the synthesized sample with high-efficiency electromagnetic wave absorption performance.

Suppressing the Radiation-Induced Corrosion of Bismuth Nanoparticles for Enhanced Synergistic Cancer Radiophototherapy.

The level of tumor killing by bismuth nanoparticles (BiNPs) as radiosensitizers depends strongly on the powerful particle-matter interaction. However, this same radiation leads to the structural damage in BiNPs, consequently weakening their specific physicochemical properties for radiosensitization. Herein, we studied the radiation-induced corrosion behavior of BiNPs and demonstrated that these damages were manifested by the change in their morphology and crystal structure as well as self-oxidation at their surface.

Preparation of Lead-free Two-Dimensional-Layered (CHNH)SnBr Perovskite Scintillators and Their Application in X-ray Imaging.

Scintillators, as spectral and energy transformers, are essential for X-ray imaging applications. However, their current disadvantages, including high-temperature sintering and generation of agglomerated powders or large bulk crystals, may not meet the increasing demands of low cost, nontoxicity, and flexible radiation detection. Thus, improved perovskite scintillators are developed in this research.
