Light-emitting electrochemical cells are next-generation light-emitting devices but the operation mechanism is still not well understood microscopically. Here, the operation mechanism of light-emitting electrochemical cells is microscopically investigated by operando observation of spin states.

Designing artificial acoustic metasurfaces via traditional numerical simulations is computationally challenging. Here, the authors introduce a data-driven neural network approach for the inverse design of membrane-type sound absorbers, testing the desired properties on two devices fabricated using model-estimated parameters.

Additive manufacturing typically uses spherical powder feedstock prepared by gas or plasma atomization. Here, a high-performance aluminum alloy is prepared from cold mechanically derived powder, showing the viability of non-spherical powders for good mechanical properties.

Controlling the formation of domain structures in ferroelectric materials is vital for their applications. Here, exposing a bulk ferroelectric oxide to water causes self-organization of ferroelectric domains, with adsorbed surface ions promoting domain coarsening.

Strong spin-orbit coupling in SrIrO₃ mixes the orbital character of iridium d-bands, resulting in correlated narrow bands and a metal-insulator transition. Here, the electric field generated by ionic liquid gating is used to manipulate the band structure, triggering a reversible control of the metal-insulator transition.

Architected materials are known for high stiffness-to-weight behavior but bending-dominated lattices are of interest for their energy absorption performance. Here, an interwoven lattice with decoupled nodes shows significantly higher compliance at similar volume fractions to traditional lattices
