ABSTRACT Inferring the climate and surface conditions of terrestrial exoplanets in habitable zone is a major goal for field exoplanet science. This pursuit will require both statistical analyses population planets as well in-depth climates individual planets. Given close relationship between habitability liquid water, it important to ask whether fraction planet’s where water can be liquid, ?hab...

During the in situ leaching process of ion-adsorption rare earths, solution needs to be constantly injected mine slopes. As a consequence, landslides are highly likely occur due increasing water level soil mass. To solve this problem, we conducted mechanical analysis on rising after injection, which shed light principle slope instability brought about by level. With variation as major factor, e...

The presence of aluminum in the weathering crust leaching rare earth ore harms subsequent extraction and separation earths. High-quality production processes must reduce content their feed liquid. Groups containing lone pairs electrons can form stable insoluble complexes with metal ions under certain conditions. In this paper, 3-hydroxyphenylphosphoryl propionic acid is used to selectively sepa...

Super-Earths and sub-Neptunes are commonly thought to have accreted hydrogen/helium envelopes, consisting of a few ten percent their total mass, from the primordial gas disk. Subsequently, hydrodynamic escape driven by core-powered mass-loss and/or photo-evaporation likely stripped much these envelopes lower-mass closer-in planets form super-Earth population. In this work we show that after und...

Some results are presented of the Earths microseismic background. It is assumed that background peaks should correspond to the resonance gravity-wave exchange in the system of two gravity-connected bodies. The microseismic spectrum is compared with the distribution of gravity potential of the nearest stars. A close peak-to-peak correspondence is found. This correspondence and resonance conditio...
