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.
Nanoscale systems are ideally suited to study quantum mechanical effects and explore these as resources for emerging quantum technology such as quantum sensing, communication or computing.
Silicon spin qubits have demonstrated some promising properties at the individual level, but the technology is beleaguered by a late start and high barriers to entry. To overcome these challenges, the quantum computing and electrical engineering communities will need to find novel ways to work together.
High-performance quantum light sources based on semiconductor quantum dots coupled to microcavities are showing their promise in long-distance solid-state quantum networks.
