Depositing textured functional materials on transparent conducting oxides remains a challenge. We demonstrate the formation of a coherent interface between a set of functional oxides and fluorine-doped-tin-oxide-based transparent conducting oxide substrate despite the lattice mismatch, owing to dimensional and chemical matching of oxygen sublattices at the interface.
Oxidation can degrade the properties and functionality of three-dimensional bulk metallic glasses. However, the formation of percolating oxide networks in metallic glass nanotubes or nanosheets can induce interesting properties, such as a recoverable strain of 10–20% and elastic modulus of 20–30 GPa, which are rarely observed in their bulk counterparts.
Oxidation normally deteriorates the mechanical properties of metals. But it is now shown that the formation of a percolating oxide network in metallic glass nanotubes can result in an unprecedented superelasticity of 14% at room temperature.
Diamond quantum magnetometry is utilized to directly read the vorticity of antiferromagnetic spin textures through coupled multi-polar emergent magnetic charge distributions.
The fundamental discoveries that enabled the development of effective mRNA vaccines against COVID-19 were awarded with this year’s Nobel Prize in Medicine.
Post-infusion poly(ethylene glycol) surface modification of chimeric antigen receptor (CAR)-engineered T cells and a subcutaneous chemokine-adsorbing hydrogel address cytokine release syndrome and the neurotoxicity side effects of CAR T cell therapy against tumours.
Piezoelectrics have longitudinal and transverse piezoelectric coefficients that are opposite in sign. Here, by tuning the interface inversion asymmetry in heterostructures, auxetic systems with positive longitudinal and transverse coefficients are realized, with expansion or contraction along all directions in an electric field.
Polymers made by click chemistry with spirocyclic building blocks form membranes that separate the components of crude oil based on molecular size and type, potentially using far less energy than distillation. Key enablers of this separation are moderate levels of polymer dynamic motion and frustrated chain packing.
A compact, time- and energy-efficient computing architecture — based on ferroelectric-defined reconfigurable two-dimensional photodiode arrays — is shown to be capable of in-memory sensing and computing.
Hybridized electron or hole states across semiconducting van der Waals monolayers in heterotrilayer systems enable the emergence of quadrupolar excitons. Quadrupolar excitons, unlike their dipolar counterparts, have a tunable static dipole moment that responds nonlinearly under an applied electric field.
The discovery of passivating agents for perovskite photovoltaics can be an arduous and time-consuming process. Now, a machine-learning model is reported that accelerates the selection of bifunctional pseudo-halide passivators. The identified pseudo-halide passivators were experimentally shown to enhance the performance of perovskite solar cells.
Heat treatment can transform some moiré superlattices into fully commensurate bilayers, where atoms in opposite layers align perfectly with each other. This structural transformation gives rise to markedly brighter interlayer excitons.
By inserting an epitaxial in-plane buffer layer of Bi5FeTi3O15, an artificial flux closure architecture enables ferroelectric polarization from a single unit cell of BaTiO3 or BiFeO3.
Three protein interaction surfaces are computationally designed into one protein subunit to enable their accurate assembly into three-dimensional crystals with user-specified lattice architectures.
Optically stimulated vibrational control for materials has the potential to improve the performance of optoelectronic devices. The vibrational control of FAPbBr3 perovskite solar cells has been demonstrated, where the fast dynamics of coupling between cations and inorganic sublattice may suppress non-radiative recombinations in perovskites, leading to reduced voltage losses.
