Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic metals and metalloids. Knowledge of the underlying processes involved in iron cycling has accelerated in recent years along wit...
In the past 10 years, ferroptosis, an iron-dependent form of regulated cell death, has become increasingly recognized as an important process that mediates the pathogenesis and progression of numerous cardiovascular diseases, including atherosclerosis, drug-induced heart failure, myocardial ischaemia–...
However,Plasmodiumspp. undergo their asexual lifecycles in the unusual environment of the red blood cell, with very high levels of iron in the form of haemoglobin. In contrast, the ubiquitous pathogenT. gondiiis a generalist and so faces different iron stresses throughout its lifecycle. We were ...
Iron oreis used directly in the steelmaking process in the blast furnace in the form of lump, pellet, and fines (seeFig. 5). (Fines are converted to sinter feed in a sinter plant.) Iron ore pellets are also used in the production of DRI and HBI. ...
The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by...

Quantifying hydrogen peroxide in iron-containing solutions using leuco crystal violet p/ pHydrogen peroxide is present in many natural waters and wastewaters. In the presence of Fe(II), this species decomposes to form hydroxyl radicals, that... Cohn,A Corey - 《Geochemical Transactions》 被引量...
Iron chloride hexahydrate is used in nutritional supplements (iron fortifiers). For infant milk powder, weaning food, etc. Definition ChEBI: A hydrate that is the hexahydrate form of iron trichloride. General Description The iron catalysts are known to be inexpensive and environmentally benign. ...
a ImcA homo-dimeric apo form predicted by AlphaFold2 (left) and its substrate analog GMPCPP-bound form (Cryo-EM, right). The secondary structure units are defined by DSSP-Stride plugin in PyMOL. And the ligand was represented with ball-and-stick, and further colored by element (N: blue,...
Among the elements selected in our simulations, we have selected the non-siderophile elements with moderate and high volatility (Fig. 1). As the pressure increases, more alloys become thermodynamically stable, suggesting some non-siderophile elements gradually tend to form alloys with Fe spontaneously...
