A highly tunable Nernst effect has been demonstrated in graphene/indium selenide devices, achieving a record Nernst coefficient at ultralow temperatures, highlighting its potential for quantum technologies and low-temperature applications.
Minimally invasive cellular-level target-specific neuromodulation is needed to decipher brain function and neural circuitry. Here nano-magnetogenetics using magnetic force actuating nanoparticles has been reported, enabling wireless and remote stimulation of targeted deep brain neurons in freely behaving animals.
Driven by carbon neutral targets, proton exchange membrane water electrolysis is becoming a hot technology due to its capability to convert fluctuating power into green hydrogen. Unfortunately, despite tremendous resources invested in fundamental research, only very few research outcomes have successfully translated into the development of industrial-scale electrolysers.
Here the authors present a pH-sensitive DNA origami nanoswitch that hides ligands for death receptors and displays them as a cytotoxic hexagonal pattern in acidic tumour microenvironments. This reduces tumour growth in a murine model of breast cancer with minimal on-target, off-tumour toxicity.
This Review explores adopting 2D semiconductors to overcome the scaling bottleneck of Si-based electronics. Recent trends and potential approaches for the development of 2D materials as a channel are discussed. Following this, the prerequisites, obstacles and feasible technologies for integrating contacts and gate dielectrics with 2D semiconductor-based channels are examined. The Review also provides an industrial perspective towards facilitating monolithic 3D integration.
A one-pot kinetically controlled synthetic framework for constructing regioselective architectures in a series of well-defined metallic heterostructures is demonstrated, in which phase and morphology regulation of Pd–Sb substrate are implemented to validate the kinetically controlled synthesis.
Simulations show that two-dimensional-material-based static random-access memory (SRAM) circuits leverage their low parasitic capacitance, counteracting performance declines due to increased interconnect resistance and potentially surpassing Si-based SRAM in terms of both performance and energy efficiency at advanced technology nodes.
Targeted black phosphorus nanosheet-based therapeutics that efficiently deliver resolvin D1 to lesional macrophages for the treatment of atherosclerosis by reducing oxidative stress and resolving inflammation have been discussed.
This Review provides a framework for processing multidimensional vision information at the sensory level and illustrates the working mechanisms as well as design principles of hardware implementations.
Mitochondrial transplantation with engineered nanomotorized mitochondria permits increased trafficking to ischemic heart tissue and recovery of cardiac function.
Inactivating hyperregulated metabolic pathways in cancer is used in the clinic to slow cancer progression. Here the authors show that l-tyrosine can reactivate melanogenesis in melanoma cells, resulting in suppression of cancer growth and production of melanin, which can be used as an additional photothermal therapy agent for melanoma eradication.
A room-temperature polaritonic valley Hall topological insulator has been developed by integrating topological photonics with perovskite-embedded optical cavities, for protected optical signal propagation along pre-designed paths.
The progression of neurological disorders might be influenced by environmental factors. Here the authors show that exposure to polystyrene nanoparticles leads to aggregation of the protein TDP-43, which is involved in amyotrophic lateral sclerosis (ALS), triggering ALS-like symptoms in animal models.
Chiral crystals are sought after for their ability to tune the polarization of light. Now, multiwalled boron nitride nanotubes (BNNTs) are shown to be promising chiral crystals with coherently stacked structures, wherein the component tubes display mono-chirality, homo-handedness and unipolarity. This unique architecture endows BNNTs with strong optical nonlinearity and a chiral geometry-dependent chiroptical response.
Combining single-molecule Förster resonance energy transfer (FRET) and fluorescence lifetime information inside an anti-Brownian electrokinetic (ABEL) trap makes it possible to distinguish dozens of biomolecules in a sample mixture. This method enables extensive barcoding of biomolecules with a minimal set of chemical components and opens up a path toward biomolecule quantification in complex mixtures.
By combining fibre-based trapping and position detection with cold damping through planar electrodes, cooling of a silica nanoparticle particle motion to a few hundred phonons on a chip is achieved.
Multiwalled boron nitride nanotubes, featuring coherently stacked structures with monochirality, homo-handedness and unipolarity among the component tubes, show a large nonlinear chiroptical response.
