Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

Astronomische Nachrichten, EarlyView.
ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Photogrammetric documentation in tunneling

Civil Engineering Design, EarlyView.
Abstract Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate

Built‐In Electric Field Effects Tailoring Solvation Sheath and Desolvation Processes of Solvated Zn2+ Toward Stable Aqueous Rocking‐Chair Zinc‐Ion Batteries

Carbon Energy, EarlyView.
TiO2/TiSe2–C heterointerfaces can create built‐in electric fields (BEFs) effects, and the intercalation mechanism is converted from the of Zn(H2O)62+ to smaller Zn(H2O)22+, featuring lower charge transfer energy barriers, faster ion transfer kinetics, suppression of HER, increased Ti–Se bond strength, and enhanced structural stabilities.

Molecular Rectangles Featuring Two Parallel NCN‐Coordinated Platinum Units: Enhancing Near‐Infrared Emission Through Excimer Formation

Chemistry – A European Journal, EarlyView.
Macro‐cycling into the near‐infrared: By incorporating two cyclometallated Pt(II) units into opposite sides of a molecular rectangle, the formation of near‐infrared‐emitting excited states that span the two units is promoted in solution, compared to the corresponding, acyclic, tweezer‐like complexes. A degree of molecular reorganization is nevertheless

Selective Recovery of Critical Minerals from Simulated Electronic Wastes Via Reaction‐Diffusion Coupling

ChemSusChem, EarlyView.
We achieve the facile separation of Fe, Dy, and Nd from model solutions of electronic waste using reaction‐diffusion coupling. Using a suite of X‐ray imaging, characterization, atomistic, and continuum simulations, we develop a predictive model for the distribution of the components in the reaction medium.

Phenol‐Rich Carbon Dots as Metal‐Free Nano‐Photocatalysts for [3 + 2] Cycloaddition Reactions

ChemSusChem, EarlyView.
Phenol‐rich carbon dots can be effectively used, in combination with a proper base and the Schreiner thiourea (A), as nano‐photocatalysts to drive synthetically relevant [3 + 2] cycloaddition reactions between cyclopropyl ketones 1 and unsaturated hydrocarbons 2. Carbon dots (CDs) are unique carbon‐based nanoparticles with potential applications in the

Monolithically Integrated Quantum Dots in a 22‐nm Fully Depleted Silicon‐on‐Insulator Process Operating at 3 K

International Journal of Circuit Theory and Applications, EarlyView.
In this paper, we describe the complete architecture for quantum control and read‐out of charge qubits designed in 22‐nm FD‐SOI process. Detail system level analysis is provided along with lab measurement results at 3 K for cryogenic control and for a quantum dot array.

Modelling Thomson Scattering in a Hydrogen Plasma at Stellar Interior Conditions Using the Hypernetted‐Chain Approach

Contributions to Plasma Physics, EarlyView.
ABSTRACT Under the extreme conditions found in small stars, where electron degeneracy and Coulomb coupling are significant, accurate modeling of Thomson scattering is crucial for determining opacity, a primary quantity for stellar energy transport.
