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 ...

Fabrication Method of Directional Microstructure for High Energy Density, High Power Battery Cathodes

Advanced Materials Interfaces, EarlyView.
Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

A DEM super resolution reconstruction method based on normalizing flow

Scientific Reports
In recent years, super-resolution reconstruction has been introduced into DEM. The process of mapping low-resolution DEM images to high-resolution DEM is highly uncertain.

Les données, le numérique et l’Anthropocène

Humanités Numériques
We have always focused on the results of scientific studies, but it is time to see data as important information, sometimes even as a result in its own right, and to question how to take care of it, particularly with an eye toward reproducibility and ...

Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Planetary science budget

Eos, Transactions American Geophysical Union, 1984
The fiscal year 1985 budget for the solar system exploration program of the National Aeronautics and Space Administration (NASA) is very promising (m/5Eos, February 14, 1984, p. 49). As announced by the Office of Management and Budget, the document includes a new start‐up program lor the MGCO (Mars Geoscience Climatology Orbiter) mission. Mixed in with
