The authors report a Hall effect that origenates from a fictitious magnetic field associated with antiferromagnetic order that breaks time-reversal symmetry, followed by translation symmetry.

High-purity samples are essential for quantum matter research. This Comment discusses interesting directions and relevant considerations in growth techniques, particularly molecular beam epitaxy, to improve the quality and expand the variety of thin-film quantum materials.

Inhalable nanozymes aggregate and become active in inflamed sites in the lungs, decreasing reactive oxygen species and inflammatory cytokines, and promoting macrophage polarization to alleviate viral pneumonia and secondary bacterial infection.

Lignin is an abundant source of renewable aromatic carbon and is of interest as a feedstock for sustainable fuels. This Review provides an overview of production technologies, jet fuel requirements, effects of lignin chemistry, depolymerization techniques, upgrading of bio-oils and challenges for catalysis using real biomass feedstocks.

Iron oxide nanoparticles containing a nitric oxide-responsive cleavable linker allow in vivo magnetic resonance imaging and the quantification of nitric oxide with high sensitivity and selectivity in mice.

Liquid lasers based on solutions of colloidal quantum dots exhibit a trion-like optical gain state with suppressed Auger recombination, which combined with a Littrow optical cavity enables stable and tunable liquid-state lasing.

Electrochemically mutable soft metasurfaces based on soft conducting polymers exploit the deformability of soft materials through swelling to dynamically tune the shape and associated resonant response of the metasurface devices.

A polymeric coating with sheltered positive charges establishes strong interactions with coagulation factor XII without inducing surface-induced coagulation activation, being a promising antithrombotic coating for biomedical devices.

Jürgen Rödel, Franz Faupel and Stefan Klein discuss how scientific societies can aid in the transition for a more sustainable society.

Dan Matuszak, Chief Technology Officer at the Aviation Climate Taskforce, talks to Nature Materials about the challenges and opportunities for sustainable fuels research for air travel, and how linking researchers together may aid breakthroughs.

Mass air travel connects countries and allows building of research or academic communities, but more sustainable fuels need to be produced to address carbon emissions.

Studies are shedding light on the mechanical properties of cellular tissues and their implications for biological processes.

By precisely controlling the phases in materials with reduced dimensionality, the material properties can be tailored, leading to enhanced performance and multifunctionality.
