Electrochromic films based on tin-doped indium oxide nanocrystals dispersed in a niobium oxide glass are now realized from solution at room temperature. The chain-like topology of niobium oxide improves the electrochemical properties of these films.
Angle-resolved photoemission spectroscopy shows that the superconducting critical temperature in optimally doped iron pnictide Ba(Fe1−xCox)2As2 can be enhanced upon Na/K surface doping.
The blood clearance mechanism, by the liver, of administered hard nanomaterials is reported in relation to blood flow dynamics, organ microarchitecture and cellular phenotype.
Anisotropic phase segregation and migration of Pt in nanocrystals is important in designing enhanced catalysts. Insight into the mechanism of Pt–Ni rhombic dodecahedra growth may provide a way to produce nanocatalysts with improved performance.
N-cadherin can alter how the stiffening extracellular microenvironment is interpreted by mesenchymal stem cells, leading to subsequent changes in downstream cell proliferation and differentiation.
The spin-switching of optically induced polariton condensates can be externally controlled with an electric field, with switching energies below 0.5 fJ.
Nanostructured plasmonic substrates are used for in situ, label-free detection, by surface-enhanced resonance Raman scattering spectroscopy, of quorum sensing in growing Pseudomonas aeruginosa biofilms.
A high-throughput virtual screening approach is used to select molecules with efficient, thermally activated delayed fluorescence. The good performance of several selected emitters in organic LED applications has also been confirmed experimentally.
Nanomechanical experiments on samples of the ordered and disordered phases of trabecular bone show a transition from plastic deformation to brittle failure.
Electrochemically induced stresses in battery electrodes leading to performance degradation are still poorly understood. In situ measurements show that stress scales proportionally with lithium intercalation rate and strain with capacity.
Coherent population-trapping studies of a single hole spin in quantum dot field-effect devices with low charge-noise performance provide insight into the anisotropy of the hole hyperfine interaction between hole and nuclear spins.
A real-time investigation shows that Ga nanoparticles in the solid γ-phase coexist with liquid Ga at a broad range of temperatures, as a result of nanoscale confinement, Laplace pressure and epitaxial matching with the substrate.
A hydrogel patch delivering a combination of gene, drug and phototherapy leads to complete tumour remission and the absence of tumour recurrence in a colon cancer mouse model.
Films based on π-stacked carbon nitride polymers are shown to bend rapidly and jump up to 10,000 times their thickness as a result of minimal variations—induced by changes in the ambient humidity or temperature—of absorbed water.
A large-area fabrication approach to achieve three-dimensional architectured metamaterials, with structural features spanning seven orders of magnitude, results in advanced mechanical properties, including high elasticity.
Strain engineering can ‘hide’ the ordinal ferrometallic state in manganite films, pushing the system to a metastable state, which can then be controlled through photoexcitation.
Metal–dielectric Janus colloids subjected to perpendicular a.c. electric fields can self-organize into swarms, chains, clusters and isotropic gases, depending on the frequency of the field.
MoTe2 is reported to host type II topological Weyl semimetal states. Two sets of Weyl points exist at different energies above the Fermi energy. Fermi arcs that form closed loops and are unique to type II Weyl semimetals are also found.
