Magneto-gas vesicles, protein nanostructures with enhanced ultrasound signal and sensitivity, enable the non-invasive, long-term and quantitative monitoring of the mechanics of three-dimensional tissues and animals.
Membrane/catalyst systems in the oxidative coupling of methane are promising for their high product selectivity but suffer from low volumetric chemical conversion rates, high capital cost and optimizing performance. A dual-layer additive manufacturing process, based on phase inversion, is now proposed to optimize a hollow-fibre membrane/catalyst system.
Encapsulation annealing leads to atomic reconstruction of transition metal dichalcogenide layers into fully commensurate structures with zero twist angle, enabling control over interfacial properties.
Self-rectifying magnetoelectric metamaterials with nonlinear responses generate electrical pulse sequences that enable precisely timed remote neural stimulation and restoration of sensory motor responses in vivo.
Lithium-rich nickel manganese cobalt oxide cathodes are widely explored due to their high capacities related to their anionic redox chemistry. A compositional optimization pathway for these materials investigating the variation of using cobalt and nickel now provides valuable guidelines for future high-capacity cathode design.
Ferroelectric dead layers can form at perovskite interfaces—a major challenge in integrating oxide thin films into devices. Here, by depositing an in-plane-polarized epitaxial buffer layer of Bi5FeTi3O15, out-of-plane polarization is demonstrated in ultrathin films down to the single-unit-cell level.
It remains challenging to integrate memory, sensing and computing in one device. Here a compact in-memory sensing and computing architecture based on ferroelectric-defined reconfigurable two-dimensional photodiode arrays has been reported.
A route to the rapid and batch production of 12 inch MoS2 monolayers is reported, which shows a synergistic optimization of scale–cost–performance metrics for a transition from lab to fab.
Extracting information about polymer network topology from mechanical properties alone remains challenging. Here the authors develop a forensic approach to quantify network structural information by analysing their nonlinear mechanics.
Polyethylene terephthalate (PET) tape is widely used for lithium-ion batteries but its chemical stability has been largely overlooked. Reversible self-discharge is now shown to be virtually eliminated in LiFePO4–graphite cells by replacing PET with polypropylene jellyroll tape.
The room-temperature self-healing behaviour of a nanotwinned diamond composite is quantitatively evaluated and found to stem from both the formation of nanoscale diamond osteoblasts and the atomic interaction transition from repulsion to attraction.
Unit-cell-thick films of metal–organic frameworks with ordered porosity would be attractive for membrane applications as these thin systems combine large molecular flux with high selectivity. Here crystalline ZIF films are grown on a crystalline substrate with high H2/N2 gas separation performance.
Trapped films of air known as plastrons are promising for underwater engineering but typically have short lifetimes. Here, aerophilic titanium alloy surfaces are developed with thermodynamically stabilized plastrons for antifouling applications.
Laminin, an important component of the extracellular matrix supporting the epithelium, hinders the typical mechanoresponse of epithelial cells to an increase in substrate stiffness, by protecting the cell nucleus from mechanical deformation.
Dynamic disorder reduces the carrier mobility in organic semiconductors (OSs) to an extent that depends on their specific electronic band structure. Here the authors study the temperature-dependent hole mobility of two structurally similar OSs and find that thermal access to transiently delocalized states enhances hole mobility in C8-DNTT-C8 compared to DNTT.
Polyethylene glycol conjugation to chimeric antigen receptor T (CAR T) cells creates a physical block between CAR T cell interactions and other immune and tumour cells, controlling tumour lysis and immune response stimulation to mitigate cytokine release syndrome.
The rational design of out-of-equilibrium demixing transitions remains challenging. Active fluids are used to control the liquid–liquid phase separation of passive DNA nanostars and establish the activity-based control of the phase diagram.
Organic luminophores emit a bright near-infrared afterglow after X-ray irradiation and outperform commercially available radio sensitizers by producing higher levels of singlet oxygen, having potential applications in precision cancer theranostics.
Two-dimensional crystals of hexagonal boron nitride become fluorescent when immersed in common solvents. Now, this phenomenon is used in the design of in-liquid sensors operating at the nanometre scale.
