Negative capacitance (NC) is a promising route towards low-power electronics. Here, a theory clarifying the connection between NC and voltage amplification is presented, and it is predicted that incipient ferroelectric states that do not necessarily maximize NC can result in a tenfold voltage amplification.
Reconstituted cytoskeleton networks linked with catch bonds display increased mechanical strength and crack resistance than those containing slip bonds, and simultaneously being more deformable, which allows for better adaptability to new mechanical environments.
The authors present evidence for the formation of commensurate charge order in non-superconducting thin films of infinite-layer nickelates, whereas they find no charge order in a superconducting film.
The existence of fast dynamics in glass solids at low temperatures is attributed to liquid-like atoms that are inherited from high-temperature liquids and exhibit behaviour similar to that of atoms in liquid states.
Desired for optical sensing or visual communications, structural colour-changing materials are hindered by the lack of scalable manufacturing. Here, by adapting Lippmann photography, large-area manufacturing of colour patterns in photosensitive elastomers is realized.
A rectified Josephson supercurrent is realized in lateral junctions using a proximitized ferromagnetic Pt barrier, with important implications for practical magnetic field free-superconducting spintronics.
Temperature-independent (Elinvar) soft elasticity with high strength, which is technologically desired but scientifically challenging, is achieved in a lightweight strain glass Mg alloy.
Photoelectrochemical devices are used for direct solar fuel production, but the stability of light absorbers can hamper their commercial prospects. Integrating a BiOI light absorber into a robust oxide-based architecture with a graphite paste conductive encapsulant results in photocathodes with long-term H2 evolution activity.
Real-time imaging of accelerated solid–liquid–gas reactions with nanobubbles uncovers the mechanisms of enhanced triple-phase reactions by identifying the critical distance between solid and gas at the nanoscale.
The interface stacking order of twisted graphene can be actively flipped between locally stable states using a mechanical impulse, and this flipping propagates spontaneously through the network in a domino-like fashion.
By exploring ultrafast magnetization in several compounds with similar crystal structures but different 4f magnetic elements, the authors show that the Ruderman–Kittel–Kasuya–Yosida interaction controls the spin dynamics.
Parallel-plate capacitors of the two-dimensional materials hBN and NbSe2 are integrated with aluminium Josephson junctions to realize transmon qubits with coherence times reaching 25 μs.
A moiré-trapped charge density wave is observed at room temperature in a twisted transition metal dichalcogenide system and attributed to local strain variation due to atomic reconstruction.
Pneumatically actuated membranes made from a chiral nematic liquid crystalline elastomer supported by poly(dimethylsiloxane) layers are assembled into pixelated colour devices, where each individual pixel can be tuned throughout the entire visible spectrum.
Atomic-scale visualization of the superfluid velocity field, the electron-pair density and the superfluid current density in an electron-pair superfluid surrounding an Abrikosov vortex in a superconducting sample of NbSe2 is demonstrated, using superconducting-tip scanning tunnelling microscopy.
A borophene polymorph with two covalently bonded boron monolayers was synthesized, expanding the physical properties of borophene and filling the gap between monolayer borophene and icosahedron-based bulk boron.
