Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

open access: yesAdvanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

The Dynamical Interaction between Low-mass Planets and Dust Coagulation

open access: yesThe Astrophysical Journal Letters
We investigate the impact of a low-mass planet on dust coagulation, and its consequent feedback on planetary migration, using a linear analysis of the coupled dust–gas hydrodynamic equations.

The SOAPS project – Spin-orbit alignment of planetary systems

open access: yesEPJ Web of Conferences, 2013
The wealth of information rendered by Kepler planets and planet candidates is indispensable for statistically significant studies of distinct planet populations, in both single and multiple systems.

Porosity Engineering of MXene Architectures: Toward High‐Performance Aqueous Electrochemical Energy Storage

open access: yesAdvanced Materials, EarlyView.
This review systematically summarizes recent advances in porosity engineering of MXenes, with a focused discussion on their structure‐governed energy storage properties. A critical analysis of structure–property relationships is presented across alkali‐ion batteries, multivalent‐ion batteries, and supercapacitors.

Trapping of giant-planet cores - I. Vortex aided trapping at the outer dead zone edge [PDF]

open access: yes, 2013
In this paper the migration of a 10 Earth-mass planetary core is investigated at the outer boundary of the dead zone of a protoplanetary disc by means of 2D hydrodynamic simulations done with the graphics processor unit version of the FARGO code.

On the Ordering of Exoplanet Systems

open access: yesThe Astrophysical Journal
We present a comprehensive analysis of planetary radius ordering within multiplanet systems, namely their ordinal position with respect to their size in a given system, utilizing data from the NASA Exoplanet Archive. In addition, we consider not only the

Predicting the Configuration of Planetary System: KOI-152 Observed by Kepler

open access: yes, 2012
The recent Kepler discovery of KOI-152 reveals a system of three hot super-Earth candidates that are in or near a 4:2:1 mean motion resonance. It is unlikely that they formed in situ, the planets probably underwent orbital migration during the formation ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
