Interaction between Iron-Aluminum Oxides and Organic Carbon in Soils with Different Parent Materials and Its Influence on Heavy Metal Migration

Yankuang ceshi
Iron-aluminum oxides, as significant mineral components, exhibit a notable influence on the organic carbon content in soil. The interaction between these two elements constitutes a crucial aspect of soil environmental processes, particularly in the ...

Photoreductive Dissolution of Iron Oxides Trapped in Ice and Its Environmental Implications [PDF]

, 2010
The availability of iron has been thought to be a main limiting factor for the productivity of phytoplankton and related with the uptake of atmospheric CO_2 and algal blooms in fresh and sea waters. In this work, the formation of bioavailable iron (Fe(II)

Interactions of proteins with biogenic iron oxyhydroxides and a new culturing technique to increase biomass yields of neutrophilic, iron-oxidizing bacteria

Frontiers in Microbiology, 2014
Neutrophilic, bacterial iron-oxidation remains one of the least understood biological reactions to date. One of the reasons it remains under-studied is because there are inherent problems with working with iron-oxidizing bacteria (FeOB), including low ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Antiferromagnetic order and spin dynamics in iron-based superconductors [PDF]

, 2015
High-transition temperature (high-$T_c$) superconductivity in the iron pnictides/chalcogenides emerges from the suppression of the static antiferromagnetic order in their parent compounds, similar to copper oxides superconductors.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Glazed roman ceramic. A multi-analytical approach [PDF]

, 2018
A multi-analytical approach has been applied to characterize ancient glazed ceramics from the archaeological sites of Magna Mater temple and Domus Tiberiana on the Palatine Hill (Rome, Italy) dated between the 3rd and the early 5th century AD. The aim

Synthesis, Characterization, and Evaluation of Boron-Doped Iron Oxides for the Photocatalytic Degradation of Atrazine under Visible Light

International Journal of Photoenergy, 2012
Photocatalytic degradation of atrazine by boron-doped iron oxides under visible light irradiation was investigated. In this work, boron-doped goethite and hematite were successfully prepared by sol-gel method with trimethylborate as boron precursor.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

GLASSES CONTAINING IRON OXIDE, X

Journal of the Ceramic Association, Japan, 1936
It is the object of this paper to set out a brief summary of the past work on the series of glasses which have been prepared from the batch mixtures in which the increasing amount of lime has been replaced by ferric-oxide or by ferrous-oxalate respectively.As the results of the total analysis of the series of lithiumoxide glasses have already been ...
