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.
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.
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.
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.
It is shown that vanadium dioxide thin films can reversibly accommodate hydrogen within their lattice structures, while demonstrating an insulator–metal–insulator phase modulation with hydrogen doping.
Plasmon-mediated growth of Au nanoprisms is demonstrated by using polyvinylpyrrolidone as surfactant, which extends the lifetime of the plasmon-generated hot electrons and makes them available to reduce Au precursors from solution.
Molecular materials are shown to have asymmetry in their elastic modulus and coefficient of thermal expansion in tension and compression, associated with terminal chemical groups that alter network connectivity.
A biocompatible and biodegradable mesostructured form of silicon is used to make lipid-bilayer-supported bioelectric interfaces that can optically modulate the electrophysiology of single dorsal root ganglia neurons.
Increasing the temperature of jet engines requires materials that are stable against degradation. Towards this goal, growth of TiAl alloys with high strength and ductility, as well as superior creep resistance, is reported at high temperatures.
Excess electrons from intrinsic defects, dopants and photoexcitation play a key role in TiO2 properties. Simulations now predict that excess electrons depend on the exposed anatase surface, the environment and the character of the electron donor.
Results from a model soap foam consisting of compressible spherical bubbles suggest that soft glassy rheology results from emergent fractal geometry in the foam’s energy landscape.
