A three-dimensional field-effect transistor array produced via compressive buckling enables accurate and minimally invasive intra- and intercellular recordings in cells and cellular networks.
Beta-alumina solid electrolyte enhanced by yttria-stabilized zirconia can provide a very low interfacial impedance with a sodium metal anode and a critical current density higher than those previously reported in lithium and sodium batteries.
Flexible neural probes, consisting of a linear array of graphene microtransistors, can be used to record from DC brain signals to high-frequency neuronal activity in awake rodents, thus showing potential for in vivo electrophysiology, and in particular epilepsy research.
The movement of fractionalized phase defects, that can be considered as fractional solitons promising for future information technology, is observed in atomic chains formed along step edges of silicon surfaces, solitons may serve as robust, topologically protected information carriers in future information technology
In magnetic double nanohelices, the balance of geometrical effects and dipolar interaction results in strongly coupled three-dimensional spin states. This leads to topological features in the stray field, offering a new route to pattern the magnetic induction.
Holographic vector-field electron tomography reveals the three-dimensional magnetic texture of Bloch skyrmion tubes in FeGe at nanometre resolution, including complex three-dimensional modulations and fundamental skyrmion formation principles.
Malignant pleural effusion (MPE) is the terminal stage of cancer and the current standard of care for MPE is largely palliative. Here the authors design a liposomal nanoparticle loaded with cyclic dinucleotide for targeted activation of STING signalling in macrophages and dendritic cells and show that, on intrapleural administration, the nanoparticle effectively mitigates the immune cold MPE and significantly augments the checkpoint blockade immunotherapy in a mouse MPE model and clinical patients’ samples.
An artificial molecular machine was designed by coupling a chemical equilibrium to a photoresponsive molecular motor. Upon light illumination, the rotary movement of the motor performs work on the chemical equilibrium generating a far-from-equilibrium state.
Quantum fluctuation in a vacuum can induce a measurable force between neutral objects in close vicinity. By dynamically modulating a system of two micromechanical oscillators near an exceptional point in the parameter space, this so-called Casimir effect can induce a non-reciprocal, diode-like energy transfer.
A strategy based on molecular intermixing of two highly miscible components enables the demonstration of high efficiency multiple-component organic solar cells.
Square-centimetre scale, multilayer superlattice structures based on atomically thin two-dimensional chalcogenide monolayers enable the realization of excitonic metamaterials.
In moiré superlattice van der Waals magnetic materials, competing interactions emerge and can stabilize new magnetic states. Here, stacking-dependent interlayer exchange interactions in small-twist-angle CrI3 bilayers yield an ordered ground state with coexisting ferromagnetic and antiferromagnetic regions.
A general versatile approach combining wet-chemistry impregnation and two-step annealing is devised for the scalable synthesis of a library of ultra-high-density single-atom catalysts with drastically enhanced reactivity.
Light-induced contraction in the out-of-plane direction in two-dimensional (2D) hybrid perovskites enables the realization of high-efficiency 2D perovskite solar cells.
A study of gold nanospheres and nanorods shows that, even without internalization, they are very efficient for siRNA delivery and inducing gene silencing in mature plant leaves.
Photoluminescence blinking is a ubiquitous phenomenon that detrimentally reduces emission stability and quantum yield. Now, an all-optical method, which employs ultrafast mid-infrared pulses, can effectively suppress the blinking of single CdSe/CdS core–shell quantum dots.
