  • There is an ongoing need to increase the operating temperature of jet engines, requiring new high-temperature materials. Here, local phase transformations at superlattice stacking faults contribute to a three times improvement in creep strength in a Ni-based superalloy.

  • Microscale resonators are widely used in modern technology and achieving large tunability of their resonant frequency is highly desirable. Here, a design for electro-superlubric springs, based on a restoring force between sliding solid surfaces, is predicted to have continuously tunable resonant frequencies from zero to several GHz.

  • Miniaturized systems for in situ plant applications are important to understand and preserve natural ecosystems. Here, the attachment of bioinspired microhooks to the surfaces of plant leaves is investigated, and on-leaf soft machines fabricated for monitoring conditions and for molecular delivery.

  • Three-dimensional magnetometers are key for detecting the motion of objects in automated electronics, but typically require multiple sensors on orthogonal planes. Here, a compact planar-type 3D magnetometer with low power consumption is realized using a topological ferromagnetic Fe-Sn heterostructure.

  • Shielding materials are crucial in protecting devices against electromagnetic radiation but are often heavyweight and operate in narrow frequency ranges. Here, highly conductive, lightweight, ultrathin, and flexible membranes based on Ag-WO3-coated polymeric nanofibers provide multispectral shielding from microwaves to X-rays.

  • Lead telluride is an important thermoelectric material but its metal-to-semiconductor transition above 230 °C is not fully understood. Here, atomic-resolution transmission electron microscopy provides structural insights into this transition, explaining the metallic behavior by a dislocation network within the rock salt structure.

  • Long coherence times are a key property of superconducting qubits, but in conventional Al-based Josephson junctions they are limited by microscopic two-level systems. Here, NbN-based qubits on Si promise to overcome this limitation, showing an energy relaxation time T1 = 16.3 μs and a spin-echo dephasing time T2 = 21.5 μs.
