Among the candidates for large-scale quantum computing devices, silicon-based spin qubits offer an outstanding nanofabrication capability for scaling-up. In an array of three spin qubits in silicon, high-fidelity state preparation and control enable the creation of a three-qubit Greenberger–Horne–Zeilinger state with 88% state fidelity.
A sustainable and biodegradable antiviral filtration membrane composed of amyloid nanofibrils made from food-grade milk proteins and iron oxyhydroxide nanoparticles can be used to trap a number of enveloped and non-enveloped viruses in water.
MoS2/hBN/graphene van der Waals heterostructures with a clean interface and optimized barrier height and gate coupling ratio enable the realization of ultrafast non-volatile flash memory.
The proposal of a FAIR-aligned Nanosafety Data Interface can advance findability, accessibility and interoperability across physicochemical, bio–nano interaction, human toxicity, omics, ecotoxicological and exposure data.
A class of biomimetic, helically folded pore-forming polymeric foldamers can serve as long-sought-after highly selective ultrafast water-conducting channels exceeding those of aquaporins with high water-over-monovalent-ion transport selectivity conferred by the modularly tunable hydrophobicity of the interior pore surface.
The combination of three techniques to study the cellular binding and uptake, and intracellular transformation of silver nanoparticles shows that despite considerable transformation, these silver nanoparticles can still be found in nanoparticulate form after a substantial amount of time.
A solid–electrolyte interphase that is permeable to Zn(ii) ions but waterproof is formed using an aqueous electrolyte composition. Cycling performances in an anode-free aqueous pouch cell show promise for intrinsically safe energy storage applications.
Semiconductor–superconductor hybrids are used for realizing complex quantum phenomena but are limited in the accessible magnetic field and temperature range. Now, hybrid devices made from InAs nanowires and epitaxially matched, single-crystal, atomically flat Pb films present superior characteristics, doubling the available parameter space.
The toxicity and complicated administration procedures of transition metal catalysts have hampered the applications of bioorthogonal catalysis in vivo. Here the authors fill the needles of a microneedle array patch with palladium nanoparticles deposited on titanium nanosheets and show that the device, applied locally on the skin of mouse models bearing melanoma, promotes intratumoural conversion of systemically injected caged doxorubicin into the active drug, reducing its toxicity and side effects.
Nanoparticle albumin bound paclitaxel (nab-PTX) is widely used in the clinic to treat different cancers, but the effect of albumin on the distribution of the drug in tumours is not clear. Here the authors show that the accumulation of nab-PTX in tumours is affected by signalling molecules involved in nutrient uptake and processing, which could be reprogrammed to increase the drug’s efficacy.
Graphene promises long-distance transfer of spin information with concomitant high charge carrier mobility. Proximity coupling of bilayer graphene with the 2D interlayer antiferromagnetic CrSBr now enables active generation of spin currents in graphene both electrically and thermally.
In situ electrostatic control of two-dimensional superconductivity is commonly limited due to large charge carrier densities. Now, by means of local gates, electrostatic gating can define a Josephson junction in a magic-angle twisted bilayer graphene device, a single-crystal material.
Magic-angle twisted bilayer graphene exhibits a wide range of phases, such as metal, insulator and superconductor states. Now local electrostatic gating devices made from this two-dimensional material platform enable highly tunable Josephson junctions, edge tunnelling spectroscopy and single-electron transistor operation.
A power generator exhibits enhanced output due to a dual-charge-carrier design. The voltage produced is constant yet competitive even under low relative humidity.
Antiferromagnets are interesting materials for fast spintronics applications, but control of the antiferromagnetic order has been limited to bulk materials so far. Now, uniaxial strain is shown to align the Néel vector in MnPSe3 down to the monolayer limit.
An electrically reconfigurable optical metasurface using a Ge2Sb2Se4Te phase change material shows half an octave spectral tuning and promising performances for optical beam steering applications.
