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.
Stacked atomic layers that interact via van der Waals forces offer a confined interlayer space for stabilizing unconventional materials or physical states, enabling a versatile platform for engineering structural configurations and properties at the atomic level.
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.
Index-matched fluorescent particles provide a system that directly visualizes ionic crystallization using confocal microscopy, and offers insight into the structure, nucleation and growth of ionic solids.
Scanning tunnelling microscopy of doped RuCl3 shows distinct charge orderings at the lower and upper Hubbard bands, which can be attributed to a correlation-driven honeycomb hole crystal composed of hole-rich Ru sites and a rotational-symmetry-breaking paired electron crystal composed of electron-rich Ru–Ru bonds.
The authors investigate the origins of chirality transfer across length scales, quantitatively demonstrating how chirality propagates from the molecular to liquid crystal level in filamentous virus systems.
Here, the authors observe that in thin films of antiferroelectric PbZrO3, substrate clamping enhances the electromechanical response, with expansion purely in the out-of-plane direction, achieving 1.7% strain for 100-nm-thick films.
The authors demonstrate a programmable topological photonic chip with large-scale integration of silicon photonic nanocircuits and microresonators that can be rapidly reprogrammed to implement diverse multifunctionalities.
Understanding the origin of photoinduced water splitting on TiO2 is crucial to control photocatalytic surface reactions. A photoexcited-hole-transfer-driven mechanism now shows that water dissociation is strongly coupled with dynamic lattice distortion (photoexcited phonons) on TiO2 surfaces.
Although structurally ordered intermetallic nanocrystals are promising electrocatalysts for fuel cells, their high-temperature large-scale preparation has proved challenging. A low-melting-point-metal-induced bond strength weakening strategy to promote alloy catalyst ordering is now proposed.
Quantum coherent control of single-photon-emitting defect spins have been reported in hexagonal boron nitride, revealing that spin coherence is mainly governed by coupling to a few proximal nuclei and can be prolonged by decoupling protocols.
Integrating electrochemically actuated soft robotics with ultra-flexible microelectrodes enables reversible and gentle wrapping around nerves for high-quality recordings.
The authors report the sweet-spot operation of germanium hole spin qubits, exploring the optimization of the external magnetic field orientation, the g-tensor and its electric tunability, and hyperfine interactions.
The detailed interplay between electronic and lattice dynamics in two-dimensional perovskite materials remains elusive. Here the authors establish the room-temperature polaronic nature of the excitons in two-dimensional Dion–Jacobson-type perovskites.
Lithium-rich oxygen-redox cathodes demonstrate high capacities, but lose energy density when cycled, showing cation disordering and formation of nanovoids and bulk molecular O2. These structural changes are shown to be a consequence of a kinetically viable and thermodynamically favoured local phase segregation mechanism.
An approach combining machine learning and combinatorial chemistry enables the creation and evaluation of ionizable lipid libraries for lipid nanoparticle formulation to effectively deliver messenger RNA to several cells and tissues.
Ultrathin and flat crystals of bismuth are grown between the atomically flat layers of a van der Waals material. These crystals exhibit outstanding electronic properties, including gate-tunable quantum oscillations of the magnetoresistance.
