  • Precise manipulation of colloids and cells is desired for material and life sciences. However, such control remains challenging without material modifications. Here, the authors achieve reversible single-particle manipulation with subwavelength resolution and high throughput using harmonic acoustics.

  • Semipermeable polymeric anion exchange membranes are essential for separation, filtration and energy conversion technologies such as fuel cells. Quasi-elastic neutron scattering is now used to disentangle water, polymer relaxation and OH diffusional dynamics in a commercially available membrane.

  • Wiring photosynthetic biomachineries to electrodes is promising for sustainable bio-electricity and fuel generation, but designing such interfaces is challenging. Aerosol jet printing is now used to generate hierarchical pillar array electrodes using indium tin oxide nanoparticles for high-performance semi-artificial photosynthesis.

  • Understanding exciton dynamics in quantum dots is important for realizing their potential in optoelectronics. Here, the authors use femtosecond transient absorption microscopy to reveal ultrafast exciton transport, enhanced at larger interdot distance and taking place within hundreds of femtoseconds after generation.

  • The oxygen evolution reaction is central to making chemicals and energy carriers using electrons. Metal hydroxide–organic frameworks are shown to act as a tunable catalytic platform for oxygen evolution, with π–π interactions dictating stability and transition metals modulating activity.

  • Two monomers with distinct solubility of their corresponding polymers in an ionic liquid enable tuning of the microstructure of the copolymers during their polymerization. Thus, energy dissipative and elastic molecular domains are created, resulting in highly tough and stretchable ionogels.

  • Lithium bis(trifluoromethanesulfonyl)imide is used as a conducting salt for rechargeable lithium metal batteries because of its stability, but corrosion with aluminium current collectors is an issue. A non-corrosive sulfonimide salt is shown to suppress anodic dissolution of an Al current collector at high potentials while improving cycling.

  • A multipole polaron, composed of a mobile electron dressed with a cloud of the quadrupole crystal-electric-field polarization, is identified in a rare-earth intermetallic.

  • Integer topological defects promote cellular self-organization, leading to the formation of complex cellular assemblies that trigger cell differentiation and the formation of swirling cellular pillars once differentiation is inhibited. These findings suggest that integer topological defects are important modulators of cellular differentiation and tissue morphogenesis.

  • Microscale architecting enables metamaterials to achieve mechanical properties not accessible to bulk materials. Here the authors show that established design protocols for the fracture of materials need to be revised to predict the failure of these materials.
