Geometric packing of tubules in the developing kidney urinary collecting system leads to tissue stiffening and rhythmic mechanical stresses local to nephron-forming niches that synchronize with tubule branching.
Defective platinum diselenide can serve as a highly efficient and stable catalyst for the oxygen reduction reaction outperforming commercial Pt/C catalysts, which is achieved by a restructuring approach via electrochemical cycling.
All-solid-state sodium-ion batteries are promising candidates for grid-scale energy storage, but they require superior solid-state electrolytes (SSEs). Here sodium-ion SSEs based on dual-anion frameworks of oxychloride are studied and found to show high ionic conductivity and electrochemical oxidative stability with mechanical softness.
A class of III–V semiconductors with memristive properties has been created by combining computational screening and experimental synthesis. The synthesized compounds have gate-tunable synaptic functions, and could be used to create energy-efficient, reprogrammable logic devices that are compatible with existing silicon technology.
A phase engineering strategy, using a device configuration consisting of 2D channel materials and patterned electrodes, has been demonstrated. It achieves various phase configurations of 2D materials and versatile functions that can be tailored in situ.
Ultrafast laser light can create emergent polar orders in specially designed thin-film heterostructures. A single-shot X-ray diffraction study, over a timescale of seven orders of magnitude, has revealed how one such polar supercrystal forms with lattice periodicities of tens of nanometres.
Increasing the electronic carrier density in the overdoped state of high-temperature superconductors enhances the critical current density due to higher efficiency of vortex pinning defects.

Monolayers of metastable 1T′-phase transition metal dichalcogenides can be rapidly grown and stabilized on 4H-phase gold nanowires, providing a hybrid system for ultrasensitive surface-enhanced Raman scattering detection.
A miniature hydrogel launcher inspired by the squirting cucumber achieves record-high jumping height through water evaporation and fracture-driven power amplification.
Electrons in solids carry orbital angular momentum in diverse non-equilibrium situations. This orbital current is often overlooked when considering electronic transport. Here we discuss how recent studies of orbital current are enabling more opportunities for technological advancements rooted in angular momentum.
Electrochemical properties of organic mixed ionic–electronic conductors depend on their microstructure in operational ionic environments. The microstructure of a model organic mixed ionic–electronic conductor across multiple length scales in both dry and hydrated states, as well as its evolution on hydration, is revealed using cryogenic four-dimensional scanning transmission electron microscopy.
A framework is presented to automate the design of flexible metamaterial structures that can execute desired nonlinear dynamic tasks and have reprogrammable functionality.
