Is the Solar System Stable?

, 2013
Since the formulation of the problem by Newton, and during three centuries, astronomers and mathematicians have sought to demonstrate the stability of the Solar System. Thanks to the numerical experiments of the last two decades, we know now that the motion of the planets in the Solar System is chaotic, which prohibits any accurate prediction of their ...

TEST OF A SOLAR-HYBRID MICROTURBINE SYSTEM AND EVALUATION OF STORAGE DEPLOYMENT

, 2010
A solar-hybrid microturbine system using a tube receiver and a Turbec T100 was tested at the Plataforma Solar de Almería. The design receiver outlet temperature of 800°C was achieved with an open receiver aperture and also using a pressureless quartz ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

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 ...

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells

Advanced Materials, EarlyView.
Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...

Control of Lagrange point orbits using solar sail propulsion

, 2008
Several missions have utilised halo orbits around the L1 and L2 previous termLagrangenext term points of the Earth-Sun system. Due to the instability of these orbits, station-keeping techniques are required to prevent escape after orbit insertion.

Carbonaceous Chondrites Provide Evidence for Late-stage Planetesimal Formation in a Pressure Bump

The Astrophysical Journal
Carbonaceous chondrites are samples from planetesimals that formed 2–4 million years after solar system formation began. They consist of distinct dust components formed at different times and locations in the accretion disk, and whose abundances in ...
