A study demonstrates that a range of different behaviours—from reversible, through weeping, to explosive—can be exhibited by a chemically homogeneous ceramic system by manipulating conditions of compatibility in unusual ways.
An all-in-one methodology for fabricating soft robotics reported here uses interfacial flows in elastomers that cure to produce actuators that can be tailored to suit applications from artificial muscles to grippers.
Propene is obtained through propane dehydrogenation using catalysts that are toxic, expensive or demanding to regenerate with ecologically harmful compounds, but the ZnO-based alternative reported here is cheap, clean and scalable.
Amorphous–amorphous phase transitions in silicon dioxide are shown to proceed through a sequence of percolation transitions, a process that has relevance to a range of important liquid and glassy systems.
By coordinating copper ions with the oxygen-containing groups of cellulose nanofibrils, the molecular spacing in the nanofibrils is increased, allowing fast transport of lithium ions and offering hopes for solid-state batteries.
An atomically coherent interlayer between the electron-transporting and perovskite layers in perovskite solar cells enhances charge extraction and transport from the perovskite, enabling high power conversion efficiency.
By depositing platinum shells on palladium-based nanocubes, the strain can be controlled by through phosphorization and dephosphorization, making it possible to tune the electrocatalytic activity of the platinum shells.
Gold nanoflake pairs form by self-assembly in an aqueous ligand solution and offer stable and tunable microcavities by virtue of equilibrium between attractive Casimir forces and repulsive electrostatic forces.
Rechargeable Na/Cl2 and Li/Cl2 batteries are produced with a microporous carbon positive electrode, aluminium chloride in thionyl chloride as the electrolyte, and either sodium or lithium as the negative electrode.
Surface enhancements in glass mobility are complicated in polymers by the interplay of the surface mobile layer thickness with a second length scale (the size of the polymer chains), giving rise to a transient rubbery surface even in polymers with short chains.
Model patchy colloids with directional bonding are designed that assemble into icosahedral quasicrystals through the propagation of an icosahedral network of bonds and may be realized using DNA origami particles.
A structured fabric constructed of linked hollow polyhedral particles (resembling chain mail) can be simply and reversibly tuned between flexible and rigid states; when it is compressed, its linked particles become jammed.
Angle-dependent magnetoresistance measurements of a strange-metal phase of a hole-doped cuprate show a well defined Fermi surface and an isotropic linear-in-temperature scattering rate that saturates at the Planckian limit.
A large violation of the Pauli limit and re-entrant superconductivity in a magnetic field is reported for magic-angle twisted trilayer graphene, suggesting that the spin configuration of the superconducting state of this material is unlikely to consist of spin singlets.
High-performance hydrodynamic simulations show that the skeletal structure of the deep-sea sponge Euplectella aspergillum reduces the hydrodynamic stresses on it, while possibly being beneficial for feeding and reproduction.
This Perspective reviews the recent technical developments in the components of the fuel cell stack in proton-exchange membrane fuel cell vehicles and outlines the road towards large-scale commercialization of such vehicles.
Two-dimensional electronic states are observed at the induced domain walls of a three-dimensional charge density wave material by manipulating the periodic lattice distortion via femtosecond infrared pulses.
Optical signatures reveal correlated insulating Wigner crystals—electron solids—in a bilayer of a two-dimensional transition metal dichalcogenide, MoSe2, with hexagonal boron nitride between the layers.
Fizeau drag of plasmon polaritons by an electron flow in strongly biased monolayer graphene is directly observed by exploiting the high electron mobility and slow plasmon propagation of Dirac electrons.
The dynamics of ions within a working lithium-ion battery are examined using optical interferometric scattering microscopy, which allows ion transport to be related to phase transitions and microstructural features.
High-energy X-ray Compton measurements and first-principles modelling reveal how the electronic orbital responsible for the reversible anionic redox activity can be imaged and visualized, and its character and symmetry determined.
Single-crystal monolayer hexagonal boron nitride is unexpectedly tough owing to its asymmetric lattice structure, which facilitates repeated crack deflection, crack branching and edge swapping, enhancing energy dissipation.
CO2 and ultraviolet light are used to initiate the p-type doping of spiro-OMeTAD:LiTFSI films, which show enhanced efficiencies when used as hole-transporting layers in solar cells and have shorter fabrication times compared with interlayers doped using conventional methods.
Optical experiments on WSe2/MoSe2 heterobilayers reveal signatures of moiré trions, including interlayer emission with sharp lines and a complex charge-density dependence, features that differ markedly from those of conventional trions.
