NASA Plans Emergency Spacewalk To Replace Key Computer On International Space Station
A pair of astronauts will venture outside the International Space Station on Tuesday for an emergency spacewalk to replace a failed computer, one of two that control major U.S. systems aboard the orbiting outpost, NASA said on Sunday. The primary device failed on Saturday, leaving the $100 billion orbiting laboratory to depend on a backup system to route commands to its solar power system, radiators, cooling loops and other equipment. The station’s current five-member crew from the United States, Russia and France were never in any danger, the National Aeronautics and Space Administration said in a statement. The Ex...

Hydrolytically stable fluorinated metal-organic frameworks for energy-efficient dehydration
We report a hydrolytically stable fluorinated metal-organic framework, AlFFIVE-1-Ni (KAUST-8), with a periodic array of open metal coordination sites and fluorine moieties within the contracted square-shaped one-dimensional channel. This material selectively removed water vapor from gas streams containing CO2, N2, CH4, and higher hydrocarbons typical of natural gas, as well as selectively removed both H2O and CO2 in N2-containing streams. The complete desorption of the adsorbed water molecules contained by the AlFFIVE-1-Ni sorbent requires relatively moderate temperature (~105°C) and about half the energy input for com...

Bragg coherent diffractive imaging of single-grain defect dynamics in polycrystalline films
Polycrystalline material properties depend on the distribution and interactions of their crystalline grains. In particular, grain boundaries and defects are crucial in determining their response to external stimuli. A long-standing challenge is thus to observe individual grains, defects, and strain dynamics inside functional materials. Here we report a technique capable of revealing grain heterogeneity, including strain fields and individual dislocations, that can be used under operando conditions in reactive environments: grain Bragg coherent diffractive imaging (gBCDI). Using a polycrystalline gold thin film subjected to...

Bottom-up construction of a superstructure in a porous uranium-organic crystal
We report a structurally complex, mesoporous uranium-based metal-organic framework (MOF) made from simple starting components. The structure comprises 10 uranium nodes and seven tricarboxylate ligands (both crystallographically nonequivalent), resulting in a 173.3-angstrom cubic unit cell enclosing 816 uranium nodes and 816 organic linkers—the largest unit cell found to date for any nonbiological material. The cuboctahedra organize into pentagonal and hexagonal prismatic secondary structures, which then form tetrahedral and diamond quaternary topologies with unprecedented complexity. This packing results in the forma...

Thermal processing of diblock copolymer melts mimics metallurgy
Small-angle x-ray scattering experiments conducted with compositionally asymmetric low molar mass poly(isoprene)-b-poly(lactide) diblock copolymers reveal an extraordinary thermal history dependence. The development of distinct periodic crystalline or aperiodic quasicrystalline states depends on how specimens are cooled from the disordered state to temperatures below the order-disorder transition temperature. Whereas direct cooling leads to the formation of documented morphologies, rapidly quenched samples that are then heated from low temperature form the hexagonal C14 and cubic C15 Laves phases commonly found in metal al...

Advances in engineering hydrogels
Hydrogels are formed from hydrophilic polymer chains surrounded by a water-rich environment. They have widespread applications in various fields such as biomedicine, soft electronics, sensors, and actuators. Conventional hydrogels usually possess limited mechanical strength and are prone to permanent breakage. Further, the lack of dynamic cues and structural complexity within the hydrogels has limited their functions. Recent developments include engineering hydrogels that possess improved physicochemical properties, ranging from designs of innovative chemistries and compositions to integration of dynamic modulation and sop...

Direction-specific van der Waals attraction between rutile TiO2 nanocrystals
We report measurement of this attraction between rutile nanocrystals, as a function of their mutual orientation and surface hydration extent. At tens of nanometers of separation, the attraction is weak and shows no dependence on azimuthal alignment or surface hydration. At separations of approximately one hydration layer, the attraction is strongly dependent on azimuthal alignment and systematically decreases as intervening water density increases. Measured forces closely agree with predictions from Lifshitz theory and show that dispersion forces can generate a torque between particles interacting in solution and between g...

Japan’s share of high-quality papers included in the Nature Index dropped by 6% between 2012 and 2016. Furthermore, while China’s rapid growth has meant that other leading nations – including the US – have also experienced a relative decline, Japan’s output has also fallen in absolute terms.

[Perspective] Atoms on the move —finding the hydrogen
Hydrogen wreaks havoc in many alloy systems, leading to embrittlement that can cause catastrophic failure. This is a serious issue for any industry that produces or uses hydrogen—affecting production, transport, storage, and use—and is a real challenge for the development of a hydrogen economy. However, the design of new materials that resist hydrogen embrittlement is limited by the difficulty of experimentally measuring or observing hydrogen; precisely locating hydrogen at the atomic scale is a notorious challenge in materials science. Other examples of where this information is required include the developmen...

Universalism—the evaluation of scientists' achievements based on merit alone rather than on functionally irrelevant factors (1–3)—has long been an unquestioned norm in science. Its existence is best illustrated by the reactions of outrage whenever a violation of universalism in science is exposed. For example, a study by Moss-Racusin et al. received a lot of attention in the scientific community because it found that when assessing application materials, science faculty rated students with male names as more competent than students who were otherwise identical but had been given female names (4).
