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.
Lattices of micrometre-sized metamaterials embedded in thermoresponsive hydrogels deform upon heating to reveal encrypted images from a blank gel canvas.
An additively manufactured AlSi10Mg alloy shows high fatigue strength, even close to its tensile strength, for micro-sized samples. The fine cells in its inherent three-dimensional network are considered as cages to limit damage accumulation.
Remotely powered vertical electrochemical transistors are demonstrated to track subtle nerve-cell activity even when the transistor core is fully shielded from the biological environment.
Oxide glasses can be intrinsically toughened by forming crystal-like, medium-range order clusters, which transform inversely to the amorphous state under stress, exciting multiple shear bands for plastic deformation.
Overcoming the intrinsic brittleness of inorganic glasses and ceramics improves structural reliability under operation, while also increasing their competitiveness for flexible devices.
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.
Self-healing behaviour in a nanotwinned diamond composite, at room temperature, has been quantitatively evaluated through tensile testing. The phenomenon is shown to arise from a transition of atomic interactions from repulsion to attraction and the formation of nanoscale diamond ‘osteoblasts’, in analogy to the process of bone healing in living organisms.
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.
