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

Vanadium dioxide is a strongly correlated material interesting for its ultra-fast resistive switching controlled by an electric-field-driven insulator-metal transition. Here, VO₂ stochastic oscillator power sensors for mm-wave to sub-THz radiation are demonstrated, displaying high responsivities, low noise, and a small scalable footprint.

The melt growth of ice - crystallization from supercooled water - has complex anisotropic kinetics, closely related to the rich variety of snowflake crystals. Here, molecular dynamics simulations shed light on its microscopic mechanism, identifying a layer of ultralow density water at the growth interface.
