Time resolved Sintering Study of PdPt Alloy Nanoparticles Supported on Al2O3 During Methane Oxidation

Andreas STIERLE · Jan-Christian SCHOBER (ORCID: 0000-0002-4084-123X) · Lydia BACHMANN · Andrea SARTORI · y 3 más

With the end of production of conventional gasoline and diesel engines as legislated by the European Parliament, alternatives like biofuels and natural gas engines will become more important in coming years. However, methane is a greenhouse gas with a 20-times higher impact than CO2. Thus, it is vital to eliminate meth...

Compound exposure of cropland to extreme precipitation and transportation disadvantage in China

Yuxin Pan · Hongyu Lyu · Haoyu Hu · Zuge Xing · y 1 más

Global climate change and extreme precipitation events pose increasing threats to agricultural systems worldwide. However, existing studies often fail to integrate the synergistic effects of precipitation, neglect the role of transportation infrastructure, and rely on data with coarse spatial resolution. To address the...

Constraints on the modified emergent dark energy model using DESI DR2 BAO

Himanshu Chaudhary · Dhruba Jyoti Gogoi · Salvatore Capozziello · G. Mustafa

In this work, we investigate the modified emergent dark energy (MEDE) model using baryon acoustic oscillation measurements from the Dark Energy Spectroscopic Instrument Data Release 2 (DESI DR2), together with CMB information from the {\tt LoLLiPoP} (low-$\ell$) and {\tt HiLLiPoP} (high-$\ell$) likelihoods based on the...

Do strategies make a difference? Evaluating the impact on video-based learning and student engagement in K-12 education

Rohr, Sebastian · Frei, Mario · Hilbert, Sven · Tepner, Oliver

Explanatory videos are central to digital and blended learning environments, especially in student-centered formats such as flipped classroom. Their instructional value depends not only on video design, but also on learners' ability to regulate their engagement with video-based content. Although research on flipped cla...

From molecular dynamics to kinetic models: Data-driven generalized collision operators in 1D3V plasmas

Yue Zhao · Guosheng Fu · Huan Lei

We present a data-driven approach for constructing generalized collisional kinetic models for inhomogeneous plasmas in one-dimensional physical space and three-dimensional velocity space (1D-3V). The collision operator is directly learned from micro-scale molecular dynamics (MD) and accurately accounts for the unresolv...

Copper doped Ce/Zr oxides catalysts derived from from mixed-metal MOFs for thermal CO2 hydrogenation

Pattaraphon RODLAMUL · Kenneth MARSHALL · Timo FELDER · Till SCHERTENLEIB

Converting CO2 to methanol is a one of the most promising process to recycle CO2. However, the selectivity and the yield to methanol of this process are low. To maximize turnover per metal site, we desire structures where every or most metal sites are exposed on a surface. Metal-organic frameworks emerged as an attract...

Ion dynamics through an order-disorder transition in a van der Waals topological material

Yuriy CHUSHKIN · Michael STÜCKELBERGER · Dina SHEYFER · Nelson HUA · y 3 más

Fe5GeTe2 is a van der Waals ferromagnet and a topological material with partially occupied Fe sites. The topological state can be tuned via slowing cooling vs. quenching at 550 K, due to the disordered vs. ordered arrangement of the Fe atom. We propose to use X-ray photon correlation spectroscopy for understanding the...

A sufficient condition for a hypergraph to have a Berge-k-factor

Gao, Yuping · Shan, Songling · Yu, Gexin

For any graph (hypergraph) $G$ with vertex set $V$ and edge set $E$, we define its incidence bipartite graph $\mathcal{I}(G)$ as the bipartite graph with bipartition $(E, V)$, where an edge $e \in E$ is adjacent to a vertex $v \in V$ in $\mathcal{I}(G)$ if and only if $e$ is incident to $v$ in $G$. This representation...

Establishing the Role of Hydrogen in Metal Plasticity

Brinthan KANESALINGAM · Sara IRVINE · Leora DRESSELHAUS-MARAIS · DAYEETA PAL · y 4 más

Hydrogen (H) is essential to decarbonize industry, but its use today is limited because it embrittles the metals and alloys required to store/distribute it. Despite 150 years of research, the fundamental mechanisms of H-embrittlement are still poorly understood. H atoms form a solid solution of interstitials in structu...
