In Situ Formation of a Melt‐Solid Interface Toward Stable Oxygen Reduction in Protonic Ceramic Fuel Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

Asteroid phase curves from Lowell observatory photometric database

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
We present results obtained from processing large photometric data base. We make use of low-precision (generally rounded to 0.1 mag) and low-accuracy (rms magnitude uncertainties of ±0.2 to 0.3 mag) data obtained from the Minor Planet Center and modified

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

Advanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Circularizing Planet Nine through dynamical friction with an extended, cold planetesimal belt

, 2018
Unexpected clustering in the orbital elements of minor bodies beyond the Kuiper belt has led to speculations that our solar system actually hosts nine planets, the eight established plus a hypothetical "Planet Nine".

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

Advanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

DIGITAL ARCHIVE OF UKRVO: THE POSITIONAL ACCURACY OF MINOR PLANETS DETERMINATIONS

Odessa Astronomical Publications, 2013
Scanning and astrometric processing of two 30x30 cm photographic plates with images of minor planets were conducted. The plates were obtained at the double wide-angle astrograph (DWAA, 400/2000) on the program of photographic sky survey and the program ...

Boosting the Energy Density of “Anode‐Free” Lithium Metal Batteries via Electrospun Polymeric Scaffolds

Advanced Functional Materials, EarlyView.
While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

Molecular Line Emission from Gravitationally Unstable Protoplanetary Disks [PDF]

, 2006
In the era of high resolution submillimeter interferometers, it will soon be possible to observe the neutral circumstellar medium directly involved in gas giant planet (GGP) formation at physical scales previously unattainable.
