Europeanization and Health Policy in the European Union During Covid‐19 Pandemic: The Case of Greece

open access: yesEuropean Policy Analysis, Volume 12, Issue 2, Spring 2026.
ABSTRACT The main purpose of this paper is to study and evaluate the efforts to respond to the covid‐19 pandemic in the EU and Greece, and to understand the capacity of the Greek health system to deal with such crises. The main questions we are called to answer are: What initiatives have been developed at EU level to address the covid‐19 pandemic? Have

Electronegativity‐Driven Frontier Orbital Engineering in B‐Ti Diatomic Synergy Enables Selective Li2C2O4 Conversion in Li‐CO2 Batteries

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

Precise Tailoring of the Coordination Environment of Single‐Atom Cu(I) on Trifurcate AlL3 Supports for Click Chemistry

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Multiscale Study of a Synergistic System in Carbon‐Coated Multimetal‐Based Selenides Toward Rapid and Highly Stable Sodium Storage

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...

Boosting Piezoelectric Voltage Constant in 3D‐Interconnected PZNNT Porous Piezoceramics via Pore Architecture Engineering

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT In conventional piezoceramics, the coordinated change between the dielectric constant (εr) and the piezoelectric charge constant (d33) usually limits the piezoelectric voltage constant g33 (g33 = d33/εr), a critical figure of merit for piezoelectric sensors.

Bimetallic Mo/Fe‐Doped CoP2 Nanoleaf Array as a Bifunctional Electrocatalyst for Overall Water Splitting

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐
