Lyophilized lymph nodes are a natural scaffold to deliver chimeric antigen receptor (CAR) T cells to tumour resection sites, where they serve as a natural T cell-supporting niche and enhance CAR T cell efficacy in reducing recurrence in preclinical tumour resection models.
Photolysis and ion migration under electrical bias cause intrinsic instability in halide perovskite solar cells. By harnessing materials that both capture and confine iodide and polyiodide ions at the perovskite surface, the stability of devices under ultraviolet irradiation, thermal–light conditions or reverse bias can be greatly increased.
Precision laser irradiation of liquid-crystal polymer networks with dynamic bonds enables reversible phase patterning to create multi-stimuli responsive materials towards wearable devices and information encryption.
Integrating electrochemically actuated soft robotics with ultra-flexible microelectrodes enables reversible and gentle wrapping around nerves for high-quality recordings.
A wide range of zero-dimensional powders can be converted into versatile, high-performance one-dimensional micro-/nanofibres by using two-dimensional cellulose sheets as a mediator, preserving the particles’ nanostructural features and acting as building blocks for complex geometric shapes to satisfy application requirements.
‘Two colour’ pump–probe experiments on yttrium iron garnet discs demonstrate how to harness dissipation of magnetic oscillations. This may have important implications for the use of magnetic materials for information processing.
Physical vapour deposition of small-molecule glass formers onto soft substrates enhances the local dynamics at the top free surface, leading to the formation of denser glasses and providing access to states deeper in the potential energy landscape.
Strong bulk van der Waals materials can be created from water-mediated densification of two-dimensional nanosheets by near-room-temperature moulding, establishing a pathway for the energy-efficient fabrication of a wide range of bulk van der Waals materials and even composites for various applications.
Liquid bioelectronics based on a permanent fluidic magnet made from three-dimensional assembled magnetic colloidal particles can be injected into the surface of the heart for cardiovascular monitoring and subsequently retrieved after use.
In a multi-principal-element VCoNi alloy, premature necking during Lüders banding has been harnessed to produce rapid dislocation multiplication, leading to both forest hardening and hardening induced by regions of local chemical order. The result is ductility of 20% and a yield strength of 2 GPa, during room-temperature and cryogenic deformation.
Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure.
Polaritonic losses, a root impediment to the many bounties of nanophotonics, may be evaded by resorting to the mathematics of synthetic frequencies offering ‘virtual’ gain.
