Weakness of Correlation Effect Manifestation in BaNi2As2: An ARPES and LDA plus DMFT Study

Daniil Yevtushynsky

The electronic spectral function of BaNi2As2 is investigated using both angle-resolved photoemission spectroscopy (ARPES) and a combined computational scheme of local density approximation and dynamical mean-field theory (LDA + DMFT). In contrast to the we ...

Iron-Catalyzed Reductive Coupling of Alkyl Iodides with Alkynes To Yield cis-Olefins: Mechanistic Insights from Computation

Xile Hu

In a recent study, a new procedure for Z-selective olefin synthesis by reductive coupling of alkyl iodides with terminal alkynes in the presence of iron salts is described. This transformation is representative of many newly developed synthetic routes thro ...

Spin cascade and doming in ferric hemes: Femtosecond X-ray absorption and X-ray emission studies

Majed Chergui, Wojciech Gawelda, Giulia Fulvia Mancini, Christopher Alexander Arrell, Frederico Alves Lima, Oliviero Cannelli, Dominik Kinschel, Camila Bacellar Cases Da Silveira, Jérémy Raymond Jean Maurice Rouxel, Rebecca Ann Ingle

The structure-function relationship is at the heart of biology, and major protein deformations are correlated to specific functions. For ferrous heme proteins, doming is associated with the respiratory function in hemoglobin and myoglobins. Cytochrome c (C ...

Mechanism(s) of electron transfer and metabolic changes during iron reduction by Clostridium acetobutylicum

Cornelia List

Microorganisms catalyze many of the redox transformations driving the iron cycle in the geosphere. For instance, iron cycling includes the reduction of solid-phase and soluble ferric iron (Fe(III)) to ferrous iron (Fe(II)). However, in order to reduce soli ...

Enhancing solar disinfection of water in PET bottles by optimized in-situ formation of iron oxide films. From heterogeneous to homogeneous action modes with H2O2 vs. O-2 - Part 2: Direct use of (natural) iron oxides

César Pulgarin, Sami Rtimi, Stefanos Giannakis

Solar disinfection (SODIS) is a well-accepted intervention method, leading to an improvement in contaminated water sources. In this work, we attempted to further enhance the bacterial inactivation process during light exposure. By means of iron oxide addit ...

The effect of iron binding on uranyl(V) stability

Rosario Scopelliti, Marinella Mazzanti, Radmila Faizova

Here we report the effect of UO2+⋯Fe2+ cation–cation interactions on the redox properties of uranyl(V) complexes and on their stability with respect to proton induced disproportionation. The tripodal heptadentate Schiff base trensal3− ligand allowed the sy ...

Enhancement of the Fenton and photo-Fenton processes by components found in wastewater from the industrial processing of natural products: The possibilities of cork boiling wastewater reuse

César Pulgarin, Stefanos Papoutsakis

Some wastewaters from the industrial processing of natural products, such as cork boiling wastewater (CBW), have been known to contain high quantities of polyphenolic compounds that are capable of forming complexes with ferric and ferrous iron and even con ...

Formation of an electron hole doped film in the alpha-Fe2O3 photoanode upon electrochemical oxidation

Michael Graetzel, Florent Alexandre Boudoire

Solar hydrogen generation by water splitting in photoelectrochemical cells (PEC) is an appealing technology for a future hydrogen economy. Hematite is a prospective photoanode material in this respect because of its visible light conjugated band gap, its c ...
