Active nematic emulsions
10.1126/sciadv.aao1470 2018-04-01 The formation of emulsions from multiple immiscible fluids is governed by classical concepts such as surface tension, differential chemical affinity and viscosity, and the action of surface-active agents. Much less is known about emulsification when one of th... |

Beyond triplet: Unconventional superconductivity in a spin-3/2 topological semimetal
10.1126/sciadv.aao4513 2018-04-01 In all known fermionic superfluids, Cooper pairs are composed of spin-1/2 quasi-particles that pair to form either spin-singlet or spin-triplet bound states. The “spin” of a Bloch electron, however, is fixed by the symmetries of the crystal and the atomic orb... |

Time-resolved structural evolution during the collapse of responsive hydrogels: The microgel-to-particle transition
10.1126/sciadv.aao7086 2018-04-01 Adaptive hydrogels, often termed smart materials, are macromolecules whose structure adjusts to external stimuli. Responsive micro- and nanogels are particularly interesting because the small length scale enables very fast response times. Chemical cross-links... |

Nonlinear fracture toughness measurement and crack propagation resistance of functionalized graphene multilayers
10.1126/sciadv.aao7202 2018-04-01 Despite promising applications of two-dimensional (2D) materials, one major concern is their propensity to fail in a brittle manner, which results in a low fracture toughness causing reliability issues in practical applications. We show that this limitation c... |

Stimuli-responsive and on-chip nanomembrane micro-rolls for enhanced macroscopic visual hydrogen detection
10.1126/sciadv.aap8203 2018-04-01 Nanomembrane rolling offers advanced three-dimensional (3D) mesostructures in electronics, optics, and biomedical applications. We demonstrate a high-density and on-chip array of rolled-up nanomembrane actuators with stimuli-responsive function based on the v... |

Inducing ferromagnetism and Kondo effect in platinum by paramagnetic ionic gating
10.1126/sciadv.aar2030 2018-04-01 Electrically controllable magnetism, which requires the field-effect manipulation of both charge and spin degrees of freedom, has attracted growing interest since the emergence of spintronics. We report the reversible electrical switching of ferromagnetic (FM... |

Light-sheet microscopy with attenuation-compensated propagation-invariant beams
10.1126/sciadv.aar4817 2018-04-01 Scattering and absorption limit the penetration of optical fields into tissue. We demonstrate a new approach for increased depth penetration in light-sheet microscopy: attenuation-compensation of the light field. This tailors an exponential intensity increase... |

Near-infrared light–responsive dynamic wrinkle patterns
10.1126/sciadv.aar5762 2018-04-01 Dynamic micro/nanopatterns provide an effective approach for on-demand tuning of surface properties to realize a smart surface. We report a simple yet versatile strategy for the fabrication of near-infrared (NIR) light–responsive dynamic wrinkles by using a c... |

Mechanism of the 2015 volcanic tsunami earthquake near Torishima, Japan
10.1126/sciadv.aao0219 2018-04-01 Tsunami earthquakes are a group of enigmatic earthquakes generating disproportionally large tsunamis relative to seismic magnitude. These events occur most typically near deep-sea trenches. Tsunami earthquakes occurring approximately every 10 years near Toris... |

Bioinspired polarization vision enables underwater geolocalization
10.1126/sciadv.aao6841 2018-04-01 With its never-ending blue color, the underwater environment often seems monotonic and featureless. However, to an animal with polarization-sensitive vision, it is anything but bland. The rich repertoire of underwater polarization patterns—a consequence of li... |
