Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Interaction of infalling solid bodies with primordial atmospheres of disk-embedded planets [PDF]
A&A 618, A19 (2018), 2018 Planets that form early enough to be embedded in the circumstellar gas disk accumulate thick atmospheres of nebular gas. Models of these atmospheres need to specify the surface luminosity (i.e. energy loss rate) of the planet. This luminosity is usually associated with a continuous inflow of solid bodies, where the gravitational energy released from ...

Advanced Functional Materials, EarlyView.This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

Global Mapping of HCl on Mars by IRTF/iSHELL
The Planetary Science JournalHydrogen chloride (HCl)—a key marker of the chlorine cycle on Mars—has been recently discovered in the Martian atmosphere by the ExoMars/TGO mission. In-orbit data indicate that this molecule appears in the atmosphere only in a limited time period and ...

Photochemistry of Planetary Atmospheres [PDF]
Eos, Transactions American Geophysical Union, 1999 From the distant, small, and icy bodies of the solar system, such as comets and Pluto, to the gas giants, Jupiter and Saturn, and the rocky inner planets (except Mercury), chemistry driven by the Sun plays a central role. Some of the most abundant constituents of the atmosphere become a principal source of a variety of minor constituents following the ...

Impact-driven planetary desiccation: The origin of the dry Venus [PDF]
Earth and Planetary Science Letters, 429, 181-190, 2015, 2015 The fate of surface water on Venus is one of the most important outstanding problems in comparative planetology. Here a new concept is proposed to explain water removal on a steam-covered proto Venus, referred to as impact-driven planetary desiccation.

Advanced Functional Materials, EarlyView.This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...

The Carbon-deficient Evolution of TRAPPIST-1c
The Astrophysical Journal, 2023 Transiting planets orbiting M dwarfs provide the best opportunity to study the atmospheres of rocky planets with current facilities. As JWST enters its second year of science operations, an important initial endeavor is to determine whether these rocky ...

Atmospheres of Hot Super-Earths [PDF]
, 2011 Hot super-Earths likely possess minimal atmospheres established through vapor saturation equilibrium with the ground. We solve the hydrodynamics of these tenuous atmospheres at the surface of Corot-7b, Kepler 10b and 55 Cnc-e, including idealized treatments of magnetic drag and ohmic dissipation. We find that atmospheric pressures remain close to their
