The authors report a Hall effect that originates from a fictitious magnetic field associated with antiferromagnetic order that breaks time-reversal symmetry, followed by translation symmetry.
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.
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.
Aluminium surface work hardening is used to create structures that cover multiple length scales, featuring precise nano-features and adaptable material options. The potential is showcased through multi-scale carbon network sensors.
Synthetic hydrogels and immune organs-on-chip mimicking human immune tissue developed from blood samples allow effective modelling of immune responses and B cell disorders, with implications for the development of improved immunotherapies and vaccines.
Two-dimensional monocrystalline gadolinium pentoxide with high dielectric constant and wide bandgap was prepared through van der Waals epitaxy, allowing the realization of sub-1 nm equivalent oxide thickness and low-power nanoelectronics.
Minutes-scale whole-cell movements fuelled by fast cytoskeletal dynamics and nuclear activity regulate mesenchymal stem cells differentiation into chondrocytes in hydrogels, being another process modulating the stem cell fate.
Benzene is a genotoxic carcinogen with no safe level of exposure. Here, by creating and decorating a structural defect in a metal–organic framework to form MIL-125-Zn, a benzene uptake of 7.63 mmol g–1 at 1.2 mbar is observed due to binding to Zn(II) sites.
The authors realize non-thermal spin switching in a canted antiferromagnet through dynamically modifying the magnetic potential using a strong multicycle terahertz magnetic near field.
In situ and computational methods are used to investigate the nature of the dense liquid phase of calcium carbonate and its transformation to the amorphous phase that is common in biomineralization processes.
Drawing inspiration from the antagonistic muscle structure found in insect wings, the authors develop a light-driven self-sustained oscillator that offers high power output.
Single-phase NaxV2(PO4)3 compositions obtained by annealing mixtures of Na3V2(PO4)3 and NaV2(PO4)3 enable the complete electrochemical extraction of Na+ through the activation of the V4+/V5+ couple. This results in a substantial increase in the energy density of such Na super ionic conductor electrodes when used in sodium batteries.
The optical spin Hall transport of exciton polaritons at room temperature is reported in a perovskite microcavity, which enables them to realize polariton spintronic devices such as a spin-polarized beamsplitter and a polariton spin inverter.
Non-reciprocal charge transport has potential for applications but is usually weak. Here the authors report a room-temperature divergent non-reciprocal Hall effect in devices made of Pt deposited on Si substrates.
Li-rich oxides were found to slowly release considerable quantities of oxygen at varying states of charge. These observations point to the intrinsic instability of oxygen in partially charged oxides and highlight the need for degradation studies.
Geometric packing of tubules in the developing kidney urinary collecting system leads to tissue stiffening and rhythmic mechanical stresses local to nephron-forming niches that synchronize with tubule branching.
