    The development of organic electronics calls for low-cost printing techniques that can prepare high quality, large-area organic single crystals. Here, Rigaset al. achieve this goal by combining spray printing and antisolvent crystallization and test the method on various materials and substrates.

    By forming heterostructures of different layered two-dimensional materials, functional spintronic devices may be built by exploiting the materials’ different spin-orbit coupling and spin transport properties. Here, the authors demonstrate a spin switch in a gated structure of graphene and MoS2.

    Electronic devices based on negative differential resistance hold promise for multi-valued logic applications. Here, the authors implement such functionalities using an atomically thin phosphorene/rhenium disulfide van der Waals heterostructure, and further demonstrate the implementation of a ternary inverter.

    Most microelectronic devices today exploit the electronic properties of semiconductors. Here, the authors demonstrate a microelectronic device for free-space electrons by using the enhanced fields in a microstructured metal surface to induce effective photoemission.

    Scalable quantum information processing requires controllable high-coherence qubits. Here, the authors present superconducting flux qubits with broad frequency tunability, strong anharmonicity and high reproducibility, identifying photon shot noise as the main source of dephasing for further improvements.

    Molecular electronics holds promise to overcome scaling limits of conventional technologies, but is currently limited to low frequency operation. Here, Trasobares et al. show radio frequencies of up to 17.8 GHz in a molecular diode based on ferrocenyl undecanethiol self-assembled monolayers on gold nanodots.

    Moving particles on a vibrating plate dates back to 1780s, but it is still challenging to control individual particles in a parallel way. Here, Zhou et al. use a single acoustic actuator and an algorithm to control multiple objects simultaneously and independently for sorting and pattern formation.

    Imaging buried interfaces is necessary to assess the quality of electronic devices and their degradation mechanisms. Here, Hirohata et al. use energy-filtered scanning electron microscopy to image buried defects in an inorganic lateral spin-valve device, at the nanometre scale and non-destructively.

    Resistive switching in metal oxides is related to the migration of donor defects. Here Baeumer et al. use in operandoX-ray spectromicroscopy to quantify the doping locally and show that small local variations in the donor concentration result in large variations in the device resistance.

    The control over the motion and deformation of liquid droplets is essential to many microfluidic and actuation systems. Zavabeti et al. demonstrate that applying a pH or ionic gradient across a droplet of liquid metal alloy of gallium results in its motion due to a breaking of the surface charge symmetry.

    Recently, negative pressure has been observed in perovskite nanowires by annealing the wires from a lower-density phase. Here, the authors show that the negative pressure enhances the piezoelectric coefficient of PbTiO3 and Pb(Zr,Ti)O3 nanowires experimentally and by ab initiocalculations.

    Thermoelectric materials with enhanced performances need to be identified. Here, the authors use the crystal field splitting energy of orbitals as a descriptor to design thermoelectric materials by solid solution maps and strain engineering in layered CaAl2Si2-type Zintl compounds.

    Flexible energy storage systems usually have limited energy densities. Here the authors report a flexible lithium–oxygen battery with the cathode consisting of titanium dioxide nanowire arrays grown on carbon textiles, which displays high mechanical strength as well as promising electrochemical performance.

    The Seebeck effect causes an electrical potential across a temperature gradient in a material, and is therefore useful for generating useful current from waste heat. Here, the authors show that the Seebeck effect can arise due to charge-carrier relaxation in addition to the conventional mechanism.

    Engineering strain in semiconductor structures provides additional control over the optical and electronic properties, which is promising for device applications. Fluegel et al. show that electronic Raman scattering provides a route to sensitively measure the degree of strain in thin semiconductor layers.

    The technological application of ultrafast terahertz magnons in itinerant ferromagnetic nanostructures is currently limited by magnon relaxation due to Landau damping. Here, Qin et al. demonstrate suppressed Landau damping and enhanced magnon lifetimes in ultrathin films of Fe–Pd alloy.

    Two-dimensional electron gases at oxide interfaces induce exotic behaviours. By studying samples with different crystal orientation, Herranz et al.show that the extension and anisotropy of the oxide quantum well properties can be controlled through selective sub-band filling via orientational tuning.

    The cheapest way to add new power stations to a domestic power grid is by tree-like connections to the network. A numerical basin stability analysis of Menck et al.suggests that this undermines a grid’s stability against blackouts but can be fixed with extra transmission lines to these otherwise ‘dead ends’.
