A Si anode with hierarchical morphology can accommodate large volume changes, demonstrates high Coulombic efficiency and cyclability as well as an areal capacity comparable to that of commercial Li-ion batteries.
Bacillus spores can be used to assemble water-responsive materials with high energy densities and to create energy-harvesting devices that can generate electrical power from an evaporating body of water.
Compressive force exerted by an atomic force microscope tip on an individual molecule adsorbed on a surface causes its emission spectrum to shift reversibly.
The otherwise random rotations of a rylene-based molecule bound to a surface are biased by the polarization direction of light impinging on the molecule.
Strong electron–phonon scattering in a quantum point contact that is driven into extreme non-equilibrium can lead to the formation of a protected subband for electrical conduction.
The spontaneous emission rate and emission intensity of dye molecules are significantly enhanced by using a nanopatterned multilayer hyperbolic metamaterial.
The transition from an indirect to direct bandgap in transition metal dichalcogenides has been observed in samples with thicknesses ranging from 8 to 1 monolayers by angle-resolved photoemission spectroscopy.
Magnetic vortices can be nucleated and propagated in an extended film by tuning the attraction between them and the electrical nanocontacts deposited on the magnetic layer.
The spin excitation energy and the magnetic anisotropy of individual atoms can be modified by varying the exchange coupling of the atomic spin to metallic leads.
