Designing catalysts to proceed with catalytic reactions along the desired reaction pathways, e.g., CO2 methanation, has received much attention but remains a huge challenge. This work reports one Ru1Ni single‐atom alloy (SAA) catalyst (Ru1Ni/SiO2) prepared via a galvanic replacement reaction between RuCl3 and Ni nanoparticles (NPs) derived from the reduction of Ni phyllosilicate (Ni‐ph). Ru1Ni/SiO...
Functional disorders of the thyroid remain a global challenge and have profound impacts on human health. Serving as the barometer for thyroid function, thyroid‐stimulating hormone (TSH) is considered the single most useful test of thyroid function. However, the prevailing TSH immunoassays rely on two types of antibodies in a sandwich format. The requirement of repeated incubation and washing further...
With the advancement of electrical and electronic devices, overcoming electromagnetic pollution turns into an urgent problem. In this work, high‐valence molybdenum (Mo6+) was doped into M‐type hexagonal barium ferrite (BaFe12‐xMoxO19) to improve its electromagnetic performance. The relationship between the Mo6+ doping concentration and the crystallographic structure, morphology and electromagnetic...
