Theoretical and experimental study on a fast proton transport pathway in CeO-coated SrTiO through surface vacancy engineering for low-temperature ceramic fuel cells.

Overcoming the high-temperature limitations of ceramic fuel cells (CFCs) requires the development of electrolytes capable of efficient proton transport at reduced operating temperatures. In this work, we introduced a surface-engineered SrTiO electrolyte coated with 10 mol%-CeO, forming a core-shell heterostructure that promoted the formation of oxygen vacancies localized at the interface. These vacancies significantly reduced the energy barrier for proton migration, enabling enhanced ionic conductivity at low operating temperatures.

Comparative analysis of structural, radiation shielding, and optical properties in ZIF-8 and BDC-Cu (MOFs) for utilization in various applications.

In this study, we conducted a comprehensive analysis of the structural properties of ZIF-8 and BDC-Cu using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Thermal gravimetric analysis (TGA).

The impact of electronic correlations on the structural stability and spectral properties of ferrocene and polyferrocene under pressure.

In this work, the electronic, spectral, and structural properties of ferrocene and polyferrocene under pressure have been investigated using DFT and DFT+DMFT methods taking into account dynamic electronic correlations. It is found that polyferrocene crystalizes in three different phases with transitions at 80 and 200 GPa. The calculated DFT+DMFT enthalpy of ferrocene and polyferrocene indicates a possibility of ferrocene transitioning into a polymerized phase at about 80 GPa.

The Spectroscopic Characterization and Photophysical Properties of a Hydrated Lanthanum Ion Complex with a Triazole Ligand by Several DFT Methods.

The experimental IR and Raman vibrational spectra of a hydrated La(III) complex with a 1,2,3-triazole ligand were characterized by using four different Density Functional Theory (DFT) levels and two accurate scaling procedures. In the theoretical calculations, the hydration water in the experimental sample was considered under the Discrete Model (DM) with different numbers of explicit water molecules and different positions around the La(III) ion and the carboxylate groups. The predicted IR spectra at the M06-2X/Lanl2dz level appear to be the closest to the experimental ones.

Selective Cyclooxygenase-2 Inhibitors in Preclinical Rodent Models of Depression and Post-traumatic Stress Disorder: A Systematic Review of Behavioral, Neuroinflammatory, and Molecular Mechanisms.

Depression and post-traumatic stress disorder (PTSD) are treatment-resistant neuropsychiatric conditions closely linked to chronic neuroinflammation. Given the limitations of current pharmacotherapies, selective cyclooxygenase-2 (COX-2) inhibitors have emerged as promising candidates for modulating neuroimmune and oxidative pathways. This systematic review evaluated the efficacy of selective COX-2 inhibitors in improving behavioral and neuroinflammatory outcomes in rodent models of chronic stress or systemic inflammation relevant to depression and PTSD.

The Two Tales of AI: A Global assessment of the environmental impacts of artificial intelligence from a multidimensional policy perspective.

Despite the rapid global expansion of artificial intelligence (AI), its environmental impacts across socio-economic contexts remain underexplored. This study evaluates the relationship between AI intensity and environmental performance across 56 countries (2013-2023), using panel econometric methods including MMQR, system GMM, and dynamic threshold modeling. The results reveal that AI activities, especially in high-intensity regimes, are significantly associated with increased CO emissions and environmental degradation, confirming the presence of a Digital Rebound Effect.

This study investigates the long-term impact of green technology innovation (GTI) on carbon dioxide emissions (CO), including transport-related emissions (COT) and the carbon intensity of GDP (COI), across twenty selected Asian developing economies. To address cross-sectional dependence and heterogeneity across countries, the analysis employs advanced panel data techniques such as Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), Pooled Mean Group (PMG), and Augmented Mean Group (AMG) estimators. The empirical results demonstrate that GTI significantly reduces CO, COT, and COI in the long run across all model specifications.
