铁(Fe)基纳米酶因其生物相容性和类似过氧化物酶的活性而被认可,有望成为肿瘤治疗的催化剂。然而,它们同时具有类似过氧化氢酶活性,通过将肿瘤组织中的过氧化氢转化为氧气,减少了羟自由基的产生,从而破坏了治疗效果。 2024年12月5日,郑州大学江冰副教授 ...

Examples include chalcocite (copper sulfide), galena (lead sulfide), cinnabar (mercury sulfide), and pyrite (iron sulfide). Sulfates, where sulfur and oxygen bind with a cation, are also common ...
Hydrogen sulfide gas causes the "rotten-egg" or sulfur water smell. Hydrogen sulfide in water causes no known health effects. However, high concentrations do change the taste of the water. Hydrogen ...
This challenging reaction, which requires the insertion of sulfur between two unactivated carbons, is catalyzed by biotin synthase, an enzyme that contains two iron-sulfur [Fe-S] clusters and SAM.
Sulfur, in the form of iron sulfide, can cause steel to be too porous and prone to cracking. Atomic number 16, atomic weight 32.064. Silicon (Si): Silicon is the second most abundant element in ...
