Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Searching for Rotational X‐Ray Modulation on TIC 277539431

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT TIC 277539431, a fast rotating M7 dwarf, was detected to host the highest latitude flare to date at 81°$$ {81}^{{}^{\circ}} $$. Magnetic activity like stellar flares occurring at high latitude indicate occurrence of coronal loops at these latitudes on fully‐convective M dwarfs. In contrast, sunspots usually occur below 30°$$ {30}^{{}^{\circ}} $

Reduction and Solid Electrolyte Interphase Formation Mechanism of Prop‐1‐ene‐1,3‐Sultone

open access: yesBatteries &Supercaps, EarlyView.
Layer‐forming additives stabilize Li‐ion cells, yet their mechanisms remain unclear. Using operando attenuated total reflection fourier‐transform infrared spectroscopy, online electrochemical mass spectrometry, electrochemical quartz crystal microbalance with dissipation monitoring, electrochemical impedance spectroscopy, and ex situ X‐ray ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Enhanced Electrooxidation of Glycerol to Lactate Over FeOx‐Modified Au Catalysts

open access: yesCarbon and Hydrogen, EarlyView.
A FeOₓ‐modified Au catalyst on nickel foam, fabricated via facile electrodeposition, achieves high‐current‐density (310 mA cm−2) and selective (78.1%) electrooxidation of glycerol to lactate at room temperature, offering a sustainable route for biodiesel by‐product valorization.

When Dihedral Angles Mask Denticity in Molecular Conductance

open access: yesChemPhysChem, EarlyView.
This study tests whether higher molecule–electrode denticity increases conductance in single‐molecule junctions. Using nonequilibrium Green's function technique in conjunction with density functional theory simulations and mechanically controlled break‐junction experiments on a tetradentate N‐heterohexacene, it is found that conductance depends mainly ...

Highly Conductive, Flexible, and Recyclable Phase Change Thermal Management Film

open access: yesEcoEnergy, EarlyView.
This Research Highlight focuses on the work that fabricates flexible, recyclable and leak‐proof phase change film via a nacre‐inspired brick‐and‐mortar strategy of shear‐induced orientation followed by hot pressing, where SEBS/POE dual physical crosslinking network and ordered graphite nanoplatelets enhance thermal conductivity, recyclability, and ...
