A nanoscale polymer layer formed by mucins at the surface of tumour cells protects them against immune cell attack. This shield can be circumvented through immune cell engineering, using chimeric antigen receptors to stimulate natural killer and T cells or by tethering glycocalyx-editing enzymes to immune cells.
Optically detected magnetic resonance (ODMR) is an efficient mechanism for quantum sensors and has been discovered in a few systems, but all have technological limitations. Here the authors report room temperature ODMR in single defects in GaN, promising for integrated quantum sensing applications.
Light-induced artificial goosebumps on liquid crystal elastomer skin are used to precisely manipulate passive microstructures, achieving a localized and controllable system for programmable micromachines.
Exploiting optical multimodal confinement, the deep-subwavelength confinement of hyperbolic phonon polaritons is demonstrated in isotopically pure hexagonal boron nitride, enabling nanoscale polariton manipulation.
Developing active and stable atomically dispersed catalysts is challenging because of weak non-specific interactions between catalytically active metal atoms and supports. A general method for synthesizing these catalysts via photochemical defect tuning for controlling oxygen-vacancy dynamics is proposed.
Considering responsive materials as transient collective assemblies rather than individual shape-changing objects allows for emergent functionalities that cannot be derived from the properties of single objects but are driven by interactions between them.
Early detection of electrical degradation can be identified by colour change due to the chromogenic response of blended molecules in dielectric polymers.
Metal monochalcogenides — a class of van der Waals layered semiconductors — can exhibit ultrahigh plasticity. Investigation of the deformation mechanism reveals that on mechanical loading, these materials undergo local phase transitions that, coupled with the concurrent generation of a microcrack network, give rise to the ultrahigh plasticity.
Oxides with a face-centred cubic anion sublattice are generally not considered as solid-state electrolytes. Li superionic conductivity in face-centred cubic oxides with face-sharing Li configurations have now been created through cation over-stoichiometry in rocksalt-type lattices via excess Li.
Intense light pulses can induce symmetry breaking, as for the generation of ferroelectricity in SrTiO3. Using ultrafast X-ray diffuse scattering at a free-electron laser, nonlinear phonon interactions that occur on such mid-IR excitation are observed, with a theory for the dynamics presented.
Soft building blocks tend to be near spherical, limiting their packing structures to those found in metallic systems. Here the authors report the spontaneous generation of highly deformed mesoatoms using molecular pentagons and observe Frank–Kasper phases not found in metal alloys.
A general process for a room-temperature, homogeneous Suzuki–Miyaura-type polymerization is reported, demonstrating a route for the scalable production of device-quality conjugated polymers.
