In this article, Szymanski et al. develop novel, cost‐effective ternary polymer solar cells printed in semi‐industrial conditions from a relatively benign ink, which do not require any further processing. These solar cells show good stability and efficiency due to balanced charge-carrier mobilities achieved by optimizing the composition and morphology. 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.

Targeting the trypanosome kinetochore with CLK1 protein kinase inhibitors
Saldivia et al. identify CLK1 as the target for the amidobenzimidazoles series of compounds. Inhibition of this protein kinase impairs inner kinetochore recruitment, causing cell-cycle arrest and cell death in trypanosomal pathogens such as Trypanosoma brucei. Read more »
Site-dependent selectivity in oxidation reactions on single Pt nanoparticles
Heterogeneous catalysis is a surface-controlled phenomenon in which different surface sites often show variations in reactivity, posing a major complication for the chemical industry. Here, site-dependent selectivity in oxidation reactions on Pt nanoparticles was identified by conducting IR nanospectroscopy measurements while using allyl-functionalized N-heterocyclic carbenes (allyl-NHCs) as probe molecules.

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.

Thermoinduced Crystallization-Driven Self-Assembly of Bioinspired Block Copolymers in Aqueous Solution
Thermoinduced crystallization-driven self-assembly of polypeptoid-based block copolymers results in delicate control over the nanostructure in aqueous solution. This provides a convenient platform for comparing cellular uptake efficiency of nanostructured assemblies with various morphologies that are otherwise similar. Read more »
Structural Features Mediating Zinc Binding and Transfer in the AztABCD Zinc Transporter System
Zinc homeostasis is critical for bacterial survival and virulence. Extracellular zinc-binding proteins play an important role in this process. This work assesses the role of several flexible or unstructured sequences in zinc binding and transfer from proteins AztD to AztC. The results provide insights into the dynamic nature of these processes and support a previously proposed structural model of transfer. Read more »
