A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments
Advanced Materials, EarlyView.The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Post-new-horizons Orbits and Masses for the Satellites of Pluto
The Astronomical JournalWe report on ephemerides for the satellites of Pluto based on the large set of astrometric measurements. Our orbit fit yielded the following masses with 1 σ uncertainties: GM _Pluto = 869.3 ± 0.4 km ^3 s ^−2 , GM _Charon = 106.1 ± 0.3 km ^3 s ^−2 , GM ...

Astrometry of the main satellites of Uranus: 18 years of observations
, 2015 We determine accurate positions of the main satellites of Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon. Positions of Uranus, as derived from those of these satellites, are also determined. The observational period spans from 1992 to 2011.

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

The Lense-Thirring effect in the Jovian system of the Galilean satellites and its measurability [PDF]
, 2005 In this paper we investigate the possibility of measuring the post-Newtonian general relativistic gravitomagnetic Lense-Thirring effect in the Jovian system of its Galilean satellites Io, Europa, Ganymede and Callisto in view of recent developments in ...

Revised Ephemerides of the Martian Satellites, Phobos and Deimos
The Astronomical JournalWe report on the new ephemerides (MAR099) for the satellites of Mars derived from a large set of ground-based and spacecraft astrometric measurements. Our integrated orbit fit yielded latest estimates for the Martian tidal parameter τ = k _2 / Q = 1.816 ±
