An in-memory factorization device, based on a phase-change material, shows enhanced capabilities in solving large-scale factorization problems due to improved energy, area and time efficiencies of the memory function.
Ionic flow through ångström-scale channels facilitates selectivity beyond steric effects between ions of same charge and hydrated diameter. Here, with two-dimensional channels, the authors show that ion position in the channel influences selectivity.
Sensory signal attributes can be disentangled exploiting the computation-in-superposition capability of hyperdimensional computing, in-memory computing and associated intrinsic device-level stochasticity.
The crystallization of nanoparticles is observed with single-particle resolution via electron microscopy. The growth modes are explained via computer simulations, unifying the understanding of crystallization from the atomic to micrometre scale.
Recent advancements in DNA nanotechnology are enabling the construction of both aesthetically pleasing and functional structures using synthetic DNA strands, paving the way for practical applications in various fields.
Approaches to treat inflammatory bowel disease with probiotics or artificial enzymes have advantages and limitations. Here we combine the advantages to overcome the individual limitations by modifying probiotics with artificial enzymes and demonstrate application in treating inflammatory bowel disease.
A simple descriptor called degree-of-isolation is proposed to describe the microenvironment and determine the effectiveness of active sites in single-site alloys. For a single-site alloy with a high degree-of-isolation, alternation of the active centre strongly affects the selectivity.
The authors use a DNA-framework-based molecular classifier to perform biomarker panel screening and analyse six biomarkers across three-dimensional datatypes to obtain a molecular taxonomy for prostate cancer diagnosis.
The n- and p-type channel characteristics of WSe2 are exploited to implement multiply–accumulate and activation functions simultaneously in an in-memory computing core.
In multilayer WSe2, dipolar excitons with Coulomb-bound electron and hole pairs located in every other layer show unique valleytronic superlattice structure and electrical tunability.
High-Tc superconducting nanowire detectors can detect single photons of telecom wavelengths at a temperature of 25 K and may enable applications in quantum sensing and quantum information processing.
Superconducting single-photon detectors are critical for quantum communication, fluorescence lifetime imaging and remote sensing, but commonly operate at very low temperatures. Now, high-temperature cuprate superconducting nanowires enable single-photon detection up to 25 K.
Differential phase contrast scanning transmission electron microscopy probes the electric field distribution across a GaN-based semiconductor heterointerface.
A semirigid stamp and a standard photolithography mask-aligner enable a reliable and scalable pickup and release process for van der Waals materials integration at the wafer scale.
Multiple alternating layers of two-dimensional materials and epilayers are grown on III–N and III–V substrates in a single growth run. Then, each epilayer is harvested by mechanical exfoliation, producing multiple freestanding membranes from a single wafer.
