By considering the topology of chiral crystals, a new type of massless fermion, connected with giant arc-like surface states, are predicted. Such Kramers–Weyl fermions should manifest themselves in a wide variety of chiral materials.
Researchers have developed a graphene plasmonics detector that is suitable for fast-response and high-resolution detection of infrared photons at room temperature.
Colloidal microparticles, with polymer composites encapsulated within two separate 2D material sheets, are fabricated by autoperforation, which can carry chemical and electronic information with long-term instability in complex environments.
Advances in understanding the physics behind remote epitaxy, a technique of growing films that ‘copy’ the substrate crystal structure through 2D material interlayer, facilitates the production of ultrathin components for device heterointegration.
This Perspective explores the history and usage of the concept of oxidation state, its relation to atomic charge and bonding, and opportunities that arise from applying this analysis to systems with mixed valence or correlated electrons.
Micromilling gem-quality diamond tips into a toroidal shape has been shown to greatly extend the accessible pressure range of standard diamond anvil cells, opening the way for studies in extreme physics of high-density matter.
A graphite and hexagonal boron nitride heterojunction enables superlubric sliding, almost independent of alignment orientation, in micrometre-sized contacts under ‘real-life’ working conditions.
Multiscale modelling provides atomic-level insights into how oxygen vacancy defect nucleation leads to the formation of the visible light photocatalyst black titania.
Physicists are searching for superconducting materials that can host Majoranas. New evidence for these elusive particles is provided by missing Shapiro steps in a Josephson effect mediated by an accidental Dirac semimetal.
The metallic state of an iron chalcogenide superconductor is demonstrated to be characterized by the simultaneous presence of itinerant carriers with different degrees of correlation. This orbital-selective metal arises from a sizeable Hund’s coupling.
A quantitative description of sound wave propagation in suspensions of self-propelled colloidal particles is achieved by combining microfluidics, video microscopy and theory.
The van der Waals material Fe3–xGeTe2 is shown to be a strong candidate for a ferromagnetic nodal-line semimetal with a very large anomalous Hall effect.
An orally administered bifunctional gastrointestinal coating has been developed and shown to limit nutrient absorption through the bowel mucosa ultimately lowering blood glucose and also acting as a platform for delivery of drugs to the gastrointestinal tract.
Line defects in two-dimensional borophene can self-assemble into new crystalline phases, blurring the distinctions between perfect and defective crystal.
Immunotherapies have shown significant promise in cancer treatment. This Review discusses how a range of materials have been employed to enhance the effectiveness of these therapies by mediating their delivery and immunomodulatory activity.
Magnetization in magnetoresistive memory devices can be controlled at room temperature by spin–orbit torques originating from the surface states of topological insulators.
Single-particle tracking of nanoparticles dispersed in the cytoplasm of living cells shows that non-specific interactions with the intracellular environment are the major contributors for the anomalous diffusion characteristics of intracellular motion.
