Summary: Constructing porous and heterojunction structures within the semiconductor oxide composites is an ideal strategy for developing gas sensing materials, but it is difficult due to grain boundaries. In this study, ZnFe2O4/SnO2 (ZFO/SNO) composite with porous core-shell spheres structure was successfully synthesized by combining pre-synthesized SnO2 nanospheres with ZnFe2O4. The porous ZFO/SNO composite with a Zn to Sn ratio of 1:0.7 showed excellent acetone sensing performance, attributed to its rich heterojunctions, porous structure, and small nanoparticle size.

Summary: One-dimensional nanostructures such as nanowires exhibit enhanced photoresponse compared to bulk materials due to unidirectional transport reducing recombination and scattering of charge carriers. CuO and Cu2O are promising transition metal oxides for efficient UV and visible light detection, forming type-II heterojunction for charge separation. Core-shell CuO/Cu2O nanowires show superior performance in terms of responsivity and detectivity, attributed to the Ohmic junction at Pd-Cu2O interface and type II heterojunction at CuO/Cu2O interface.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
