57Fe Mössbauer spectroscopy investigation of La0.7Ca0.3Mn0.5Fe0.5O3

Results in Physics, 2016
A La0.7Ca0.3Mn0.5Fe0.5O3 (LCMFO) ceramic sample was produced using conventional solid-state reactions. According to the X-ray diffraction data, the obtained sample has an orthorhombic space group Pnma (a = 5.482(2) Å, b = 7.739(3) Å, c = 5.446(3) Å ...

Layered π Systems Based on Ferrocenophanes

European Journal of Inorganic Chemistry, EarlyView.
Syntheses of a variety of ferrocenophanes and extensions of their π systems are reported. These are performed by Knoevenagel reactions and predominantly lead to syn diastereomers. Eight ferrocenophanes were crystallographically characterized. [1.1]Ferrocenophane was prepared by the literature method along with a small amount of [1.1.1.1]ferrocenophane,

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

Journal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

Small, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...
