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 ...

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Advances in Triboelectric Nanogenerators With Rotating Structure

open access: yesCarbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Copper(II), a Peculiar Metal Ion for Complexation with Monensin A Ionophore

open access: yesChemistry – A European Journal, EarlyView.
Copper(II) forms three chiral and EPR‐active complexes with monensinate A in methanol. Beside the bis [CuL2] and mono [CuL]+ species, the new dinuclear construct [Cu2L]3+ exhibits an [ML]+‐type and a metal salt‐type copper(II) centers weakly bound to each other through counter ion(s) and thus, being magnetically independent.

Magnetic Dynamics and Elongated Coherence of a High‐Spin Mn(II) Qubit Doped into a Metal‐Organic Framework

open access: yesChemistry – A European Journal, EarlyView.
This study demonstrates that dilute Mn(II) (∼0.02 mol%) doped into the Zn(II)‐MOF [CH6N3][Zn(HCOO)3] act as high‐spin (S = 5/2) spin qubits, achieving microsecond phase memory times above 50 K—the first report for Mn(II)‐based systems. Robust hydrogen‐bonding networks suppress relaxation and stabilize the lattice, extending T2.
