In recent years, there has been a proliferation of models for spin-dependent electronic processes in organic semiconductors. Researchers aiming to utilize these processes for new organic spintronics devices should focus more on scrutinizing these models experimentally by embracing spectroscopy.

Extremely sensitive and ultrasmall superconducting quantum interference devices can be fabricated on sharp nanoscale tips.

A combination of self-assembly and jet printing can be used to create block copolymer films with complex structures and tunable periodicities across a large substrate.

The local curvature of dumbbell-shaped nanoparticles can be used to control the ionization state of a molecular layer adsorbed on their surfaces and the self-assembly patterns of the particles.

The conductance of an electronic nanodevice can be switched by an applied current between two well-defined values, which correspond to atomic configurations that differ as a result of the rearrangement of a single atom.

Condensed-matter physicists are steadily closing in on exotic excitations known as Majorana modes that could advance both fundamental science and quantum computing.

Artificial honeycomb lattices offer a tunable platform for studying massless Dirac quasiparticles, and their topological and correlated phases.

Excitonic valley quantum coherence is optically generated and detected by polarization-resolved photoluminescence spectroscopy in the monolayer semiconductor WSe₂.

Nanoscale superconducting quantum interference devices (SQUIDs) fabricated on the apex of a sharp tip can provide spin sensitivities that are nearly two orders of magnitude better than previous SQUID sensors.

Electromigration is used to rearrange single atoms in an atomic-sized metal contact and to switch its conductance between two well-defined values, enabling memory device functionality.

Double-nanocrystal systems can be used as an alternative to rare earth-doped dielectric quantum dots for upconversion luminescence.

Full control by electric gates can be accomplished in exchange-driven spin qubits.

The solution–liquid–solid process is carried out in a microfluidic reactor to support the continuous synthesis of semiconductor nanowires in solution.

Three-dimensional films — comprising polymeric phases of different molecular weights and compositions — are arranged in complex hierarchical patterns and used for wafer-scale patterning.

The chemical properties of a molecular monolayer on the surface of a non-spherical nanoparticle depend on its local curvature; an effect that can be exploited to drive the self-assembly of these nanoparticles into different structures.

Fluorescent nanodiamonds can be used to tag implanted lung stem cells and follow their uptake and regeneration in host tissue.
