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

Advanced 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 ...

Isotopic Compositions and Elemental Abundances of Chromium in Presolar Silicon Carbide Grains from Asymptotic Giant Branch Stars

The Astrophysical Journal
Isotopes of chromium (Cr) and other iron-group elements are predominantly made in the inner shells of supernovae and are later reprocessed via the slow neutron capture process ( s -process) in asymptotic giant branch (AGB) stars.

Level lifetimes in 52Cr from DSAM following inelastic neutron scattering: Implications for shape coexistence and E0 strengths [PDF]

EPJ Web of Conferences
Nuclear shape coexistence is a widespread but not yet well understood phenomenon. Electric monopole (E0) transitions are a particularly sensitive probe of shape coexistence.

Beta-decay properties of neutron-rich Ca, Ti, and Cr isotopes

, 2018
Beta-decay properties of neutron-rich Ca, Ti, and Cr isotopes are studied within a deformed proton-neutron quasiparticle random-phase approximation. The underlying mean field is described self-consistently from deformed Skyrme Hartree-Fock calculations ...

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Exposure risks of trace metal(loid)s on little egrets in a restored polymetallic mining area in eastern China

Global Ecology and Conservation, 2023
Trace metal(loid) pollution from mining activities is a widespread environmental problem, which has stimulated restoration efforts over the world. Tongling is a non-ferrous metal mining area in China with a long history of mining activities.

Molecular and isotopic indicators of alteration in CR chondrites [PDF]

Meteoritics & Planetary Science, 2006
The CR group of carbonaceous chondrites may represent some of the most primitive extraterrestrial materials available for analysis. However, in contrast to other chondrite groups, the CR organic fraction is poorly characterized. The carbonaceous chondrite literature shows that relatively anhydrous thermal processing results in a condensed, poorly ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Measurement of Radon (222Rn) Concentrations in the Basaltic Rocks of Yarmouk River, Jordan

Iraqi Geological Journal, 2021
This article was conducted to measure radon concentration levels in the Yarmouk River Basalt (YRB), North-Jordan. The YRB is of Quaternary in age and occurred as a successive sheet with a total thickness of 122 meters.
