Recent Advances in Prussian Blue Analogs as Capacitive Deionization Electrode Materials: Fundamentals, Structure–Performance Relationships, and Design Strategies

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review systematically examines the fundamental ion‐storage mechanisms, the structural chemistry, and redox behavior of Prussian blue analogs as Faradaic electrodes in capacitive deionization, their intrinsic limitations and engineering optimization strategies, and the critical materials‐to‐device considerations required to advance PBA‐based CDI ...

Structure and Magnetic Properties of Bi5Ti3FeO15 Ceramics Prepared by Sintering, Mechanical Activation and Edamm Process. A Comparative Study

Archives of Metallurgy and Materials, 2016
Three different methods were used to obtain Bi5Ti3FeO15 ceramics, i.e. solid-state sintering, mechanical activation (MA) with subsequent thermal treatment, and electrical discharge assisted mechanical milling (EDAMM).

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 ...

Cation Distribution in Natural Chromites from Oman

Sultan Qaboos University Journal for Science, 1996
Two specimens or natural chromite from the Oman ophiolite were studied using Mossbauer Spectroscopy (MS), X-ray Diffraction (XRD). and Scanning Electron Microscopy (SEM). The diffraction patterns obtained at room temperature showed that the two specimens

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 ...

Fully Compensated Ferrimagnetic Properties of (Cr,Fe)S Compound with a Pyrrhotite‐Type Structure

Small, EarlyView.
Pyrrhotite‐type crystal structure of (Cr,Fe)S compound. The fabrication conditions for obtaining a single phase of the non‐equilibrium phase were optimized. The temperature dependence of the magnetization exhibits the typical behavior of compensated ferrimagnetism. A large magnetic coercivity of the (Cr,Fe)S compound.
