2D magnetic materials have recently attracted significant interest as model systems to understand low-dimensional magnetism and for potential spintronic applications. Here, we report on synthesis of Cr2TiC2Tx MXene and a detailed study of its magnetic as well as electronic properties. Read more »

Domain-Swap Dimerization of Acanthamoeba castellanii CYP51 and a Unique Mechanism of Inactivation by Isavuconazole
We investigated the mechanism of action of antifungal drugs in the human pathogen Acanthamoeba castellanii. We discovered that the enzyme target formed a dimer via an N-termini swap, whereas drug-bound AcCYP51 was monomeric. Cover image shows a molecular model of the AcCYP51 dimer in a phospholipid bilayer. Read more »
Rational Design of a Uranyl Metal–Organic Framework for the Capture and Colorimetric Detection of Organic Dyes
Diffraction data for a new uranyl-containing metal–organic framework reveals a structure of interpenetrating 3D nets with large pores. The material is stable in aqueous media and due to the large void space (constituting 76% of the unit cell by volume) can sequester organic dyes, the uptake of which induces a visible change to the color of the material.

Design and synthesis of high performance flexible and green supercapacitors made of manganese‐dioxide‐decorated alkali lignin
Researchers synthesized a plant‐based composite electrode for use in flexible supercapacitors and used synchrotron x‐ray microtomography to better understand the impact of microstructure and morphology on electrode porosity and electrical conductance. Read more »
Magneto-structural studies of an unusual [MnIIIMnIIGdIII(OR)4]4− partial cubane from 2,2′-bis-p–tBu-calix[4]arene
TBC[4] is a molecular framework that has proven to be a highly versatile ligand for the synthesis of a breadth of polymetallic transition metal, lanthanide metal, and 3d–4f complexes. We outline the synthesis, structure and magnetic behaviour of a new bis-TBC[4]-supported complex, together with theoretical magneto-structural studies examining the exchange interactions. Read more »
Controlling Magnetization Vector Depth Profiles of La0.7Sr0.3CoO3/La0.7Sr0.3MnO3 Exchange Spring Bilayers via Interface Reconstruction
Polarized neutron reflectometry was combined with soft x-ray magnetic spectroscopy to quantify the changes in the magnetic and chemical depth profiles in La0.7Sr0.3CoO3/La0.7Sr0.3MnO3 bilayers, confirming the formation of interfacial layers with distinct magnetization and chemical density.

Reversible Room-Temperature Fluoride-Ion Insertion in a Tunnel-Structured Transition Metal Oxide Host
Fluoride ions show promise as charge carriers in batteries but have limited cyclability. Here we show the reversible and homogeneous topochemical insertion/deinsertion and bulk diffusion of F ions within the one-dimensional tunnels of submicrometer-sized FeSb2O4 particles at room temperature.

Time‐Dependent Cytotoxic Properties of Terpyridine‐Based Copper Complexes
The cover feature picture shows the progressive activation of terpyridine‐based copper(II) compounds that are not cytotoxic against various cell lines after 24 h of incubation but become highly efficient after 72 h of incubation, with IC50 values in the low‐micromolar to nanomolar range.

Controlling antiferromagnetic domains in patterned La0.7Sr0.3FeO3 thin films
Antiferromagnetic spintronics have gained interest because they can be controlled at terahertz frequencies and are insensitive to external magnetic fields. Due to dimensional confinement as well as microstructuring by ion implantation, the spin axis of an antiferromagnetic oxide can be robustly controlled in a deterministic way up to room temperature.

Divergent Adsorption-Dependent Luminescence of Amino-Functionalized Lanthanide Metal–Organic Frameworks for Highly Sensitive NO2 Sensors
A novel gas-sensing mechanism exploiting lanthanide luminescence modulation upon NO2 adsorption is demonstrated. Two isostructural lanthanide MOFs are used, including an amino group as the recognition center for NO2. Energy transfer from the ligands to Ln is strongly dependent on the presence of NO2, resulting in an unprecedented photoluminescent sensing scheme. Read more »
