Mixed ionic–electronic transport in conducting polymers remains poorly understood. Here the authors observe non-equilibrium electronic transport when counterions are unable to equilibrate in response to gate-injected electronic carriers.
Helical motifs in dense inorganic solids have remained exceedingly scarce. Now a type of 1D van der Waals helical crystal, GaSeI, is presented that manifests the rare quasi-periodic Boerdijk–Coxeter helix motif.
High-pressure experiments performed on aperiodic TRUMOF-1 demonstrate that this material remains crystalline up to pressures of 1.8 GPa, higher than other cubic metal–organic framework, due to the heterogeneous distribution of different shock-absorption mechanisms throughout the material.
Metal halide perovskite (MHP) materials could revolutionize photovoltaic (PV) technology but sustainability issues need to be considered. Here the authors outline how MHP-PV modules could scale a sustainable supply chain.
Propulsive motion in soft robotic systems requires the power amplification of stored energy. An accumulated strain energy-fracture power-amplification method is used to create light-driven soft robotic systems with a controlled launching ability.
The authors report very high in-field critical current densities in Fe-based superconductors. They achieve this through doping to increase the carrier density and adding defects to pin vortices.
Microbial products only work if the microorganisms are kept alive — usually through the use of cold chains. High-throughput mapping of the microbial–material combinations landscape generated specific dry formulations that enable the microorganisms to survive extreme storage and processing conditions.
Scanning tunnelling microscopy and scanning tunnelling spectroscopy have been used to observe intra-unit-cell nematic order and associated Fermi surface deformation in ScV6Sn6.
The instability of n-type organic semiconductors in air is a long-standing challenge in organic electronics. Now, a strategy based on the use of vitamin C is developed to stabilize organic semiconductors. Vitamin C scavenges reactive oxygen species and inhibits their generation, improving the performance and stability of organic semiconductors and their electronic devices.
An oral inulin allergen gel restores the microbiota of allergic mice and suppresses undesired immune responses to achieve allergen-specific oral tolerance, effectively overcoming food allergy.
The generation of attosecond pulses has opened the door to probing electron dynamics at sub-atomic scales. Beyond atomic physics, this field is envisioned to also have a decisive impact on condensed-matter physics, chemistry and biology.
A high-throughput screen of substances generally recognized as safe identifies species-specific materials that stabilize live microbial therapeutics as powders, making them robust to pharmaceutical manufacturing workflows.
Hydrogel force sensors directly bioprinted into embryonic tissues quantify the forces driving tissue remodelling and reveal the existence of mechanisms that counteract tissue morphogenesis.
Patient-derived pancreatic cancer organoids grown in engineered matrices acquire chemoresistance due to the increased expression of drug efflux transporters, promoted by CD44 receptor interactions with hyaluronan in the stiffer tumoural matrix.
The synergy between the field-induced antiferroelectric to ferroelectric phase transition and substrate constraints results in enhanced electromechanical responses.
Harnessing the large-scale integration and individual control of artificial atoms on silicon photonic circuits enables the realization of a rapidly programmable topological photonic chip that can be dynamically reconfigured to explore diverse topological phenomena.
Researchers have demonstrated that skyrmion-like topological spin textures can be created in a controlled manner via the local application of an electric field with a tip electrode on a multiferroic BiFeO3 thin film.
