The realization of seawater electrolysis requires high‐performing anode materials that should possess good catalytic activity, stability, and specificity for the oxygen evolution reaction (OER) as well as high resistance toward chloride corrosion. Herein, the design of a multilayered oxygen‐evolution electrode is reported to meet the multiple needs of anode material for saline water splitting. The multilayered electrode is synthesized through direct thermal boronization of commercially available NiFe alloy plate with boron powder, followed by electrochemical oxidation. And this electrode is composed of the surface oxidized NiFeBx alloy layer, the NiFeBx alloy interlayer, and the NiFe alloy substrate. The boron species are present in the form of metaborate in the outermost oxidized NiFeBx layer, and their existence is conductive to the generation and stabilization of the catalytic active phase γ‐(Ni,Fe)OOH. The introduction of NiFeBx interlayer effectively prevents the excessive oxidative corrosion of the anode material in the electrolyte containing chloride ions.

Nanoselenium is a promising selenium supplement as a result of its low toxicity and high bioavailability. However, the understanding on the preparation, stability, bioavailability, possible risks, and related underlying mechanisms of nanoselenium is not in-depth. Thus, the above aspects were reviewed on the basis of the latest literature. The reducing capacity and stability of the reducing agent and binding force between nanoselenium and the template decide the nanoselenium stability. Although research on nanoselenium application in food, agriculture, livestock, and aquaculture has been widely carried out, it is not widely applied in the fields. Se-containing amino acids are synthesized using nanoselenium adsorbed by organisms, and they constitute Se-containing proteins with other amino acids, which improves the health of organisms via scavenging excessive radicals. Notably, excessive nanoselenium intake generates redundant Se-containing amino acids, leading to dysfunction of key proteins in organisms, and its toxic doses vary with organisms. Furthermore, some issues related to nanoselenium still need to be solved urgently.

The development of oxide semiconductor-based gas sensing materials that can sensitively detect benzene compounds (e.g., xylene) is highly desirable but challenging due to their inherently low chemical reactivity. Herein, we...
