A single layer of La atoms placed on the tip of a LaB6 nanowire suppresses chemical reactions and promotes emission of free electrons, creating an electron source with very low noise and high stability.
A DNA-based rolling motor that is powered by RNA hydrolysis has a maximum speed and processivity that is three orders of magnitude greater than conventional DNA-based walkers.
The light-powered assembly and disassembly of functionalized nanoparticles creates dynamic nanocavities with built-in selective uptake, reactivity and release.
A theoretical framework that interprets Raman scattering as an optomechanical process can be used to understand, and guide, experiments in surface-enhanced Raman spectroscopy.
A cavity optomechanics model accounting for the intrinsic dynamics of the interaction between plasmons and molecular vibrations reveals a parametric amplification mechanism that may provide an explanation for features recently observed in nonlinear Raman spectroscopy experiments.
Colloidal nanocrystals functionalized with light-responsive ligands can be cyclically assembled and disassembled to create nanoscale environments where chemical reaction rates are enhanced and stereoselectivities can be controlled.
Effective magnetic fields as high as 30 T can arise in magnetically doped nanocrystals due to spin fluctuations alone, and can now be observed using ultrafast optical spectroscopy.
Cantilevers made of SrTiO3 grown on silicon use the flexoelectric effect to achieve electromechanical performances similar to piezoelectric bimorph cantilevers.
A violation of Bell's inequality, which is a direct proof of entanglement, can be observed in the solid state using the electron and nuclear spins of a single phosphorus atom in silicon.
Conductance switching with high-to-low ratios as high as 1,000 can be triggered by an electric field in rigid organometallic molecules containing a redox-active centre and a spin-polarized ground state.
Magnetic switching in spin–orbit-torque devices can be controlled by the geometry of the device, allowing different functionalities to be created from the same system.
This Review discusses the advances in synthesis, assembly, ligand treatments and doping that have enabled the fabrication of high-mobility quantum dot solids.
Data-driven analytical techniques can quantify the expected return of alternative research efforts relative to their cost, and can be used to prioritize research investments as shown here for hazard classification of some nanomaterials.
