Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Análisis del Real Decreto 1155/2024, por el que se aprueba el nuevo Reglamento de Extranjería en España: Avances, retrocesos y oportunidades perdidas en el acceso a una autorización de residencia

open access: yesRevista Vasca de Administración Pública
This article explores Royal Decree 1155/2024 in the areas most closely linked with the authorization by ties to the community. Numerous studies criticized the problems of the previous regulation, and the new regulation calls for a review of these ...

Ditched and walled enclosures in Prehistoric Iberia (4th-3rd millennia cal. BCE): Like oil and water

open access: yesLucentum
Iberian Copper Age «ditched» and «walled» enclosure sites are often thought to represent two clearly distinguishable groups of sites. However, the discovery of sites where both ditches and walls are present («mixed sites») complicates things.

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

A High‐Performance Oxidized Graphene for Dendrite‐Free Anodes and Kinetically Enhanced Cathodes of Aqueous Zn‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Oxidized graphene rich in carboxylic acid groups obtained via a simple electrochemical exfoliation route is shown to tackle the main challenges of aqueous Zn‐ion batteries (AZIBs), specifically short Zn anode cycle life and sluggish cathode reaction kinetics.

Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.
