Interface-engineered 1T/2H-MoS2 on 3D nickel foam enables accelerated hydrogen evolution kinetics

We report a single-step pulsed electrodeposition strategy that grows mixed-phase 1T/2H-MoS 2 conformally on a porous nickel foam (NF) scaffold, yielding a self-supported MoS 2 /NF electrode. In 1.0 M KOH, MoS 2 /NF requires only an overpotential of −52 mV to deliver −10 mA cm −2...

Widespread thermophilization but weak link to climate warming in Europe’s summit plant communities

Abstract Recent changes in alpine vegetation are often attributed to climate warming, particularly community composition shifts towards more warmth-associated species, or thermophilization. Here we assess the link between thermophilization and warming across 53 European mountain...

Dependence of Extreme Values, VaR, and Contagion During the COVID-19 Period: Analysis Using the Copula-GARCH Approach

The present study investigates extreme co-movements and financial contagion across a broad set of global financial markets, including ten developed and emerging stock market indices, commodities (gold and oil), and cryptocurrencies (Bitcoin), over the period from January 2007 to...

Effects of Dapagliflozin on the Bone of Patients with CKD on Dialysis

The effects of gliflozins on bones of CKD patients on dialysis are unknown. Recently, SGLT2 expression in bone tissue of patients with CKD has been reported. We hypothesized that dapagliflozin may act in bone cells and modulate the Klotho-FGF23 axis. This study analyzed the effec...

Biopsychosocial education improves workers’ low back pain beliefs in a meat processing plant

Background Low Back Pain (LBP) is a major health problem at work. While prevention measures can focus on physical risk factors, negative beliefs about pain can also contribute to LBP chronicity. Objective This study evaluates the impact of educational training based on the biopsy...

Chance of live birth in women with recurrent pregnancy loss referred to a French assisted reproductive technology center

Recurrent pregnancy loss (RPL) is a multifactorial condition, with over 50% of cases remaining unexplained. The absence of therapeutic consensus raises questions regarding referral for assisted reproductive technology (ART). To evaluate live birth rates and predictors of success...

EPISTEMOLOGICAL SYNTHESIS NOTE The Structural Unity of the PEG Theory: From the Meta-Evolution of Complex Systems to the SAT and CEAF Models

This epistemological synthesis note formalizes the structural and conceptual unity of an interdisciplinary research program driven by the Evolutionary Potential Gradient (PEG) framework. Addressing the limitations of static or purely kinetic analyses of change, this text delivers...

From Mining Informality to Public Financial Capacity: An Institutional Approach to the Formalization of Artisanal Mining Value Chains in the Democratic Republic of Congo

This concept note proposes an innovative institutional approach to the formalization of artisanal and small-scale mining (ASM) value chains in the Democratic Republic of Congo (DRC). Grounded in institutional economics and political philosophy, the research challenges purely coer...
