Summary: Ruddlesden-Popper and reduced Ruddlesden-Popper nickelates are potential substitutes for high-temperature superconducting cuprates, but the extent of their similarity has been contested. Resonant inelastic x-ray scattering (RIXS) has been crucial in studying their electronic and magnetic excitations, but inconsistent results among different samples and the absence of publicly available data have hindered detailed comparisons. To address this, we present open RIXS data on La4Ni3O10 and La4Ni3O8.

Summary: 1s2p resonant inelastic X-ray scattering (1s2p RIXS) has been successful in determining the differential orbital covalency (DOC) in highly covalent iron environments, but the presence of non-centrosymmetric environments with metal-oxo bonds introduces 4p character into 3d orbitals, impacting electronic structure analysis. This study examines the effects of 4p mixing on 1s2p RIXS spectra using binuclear oxo bridged Fe(III) complexes and elucidates the selective nature of the mixing for enhancing L-edge XAS analysis in terms of DOC. Additionally, the study provides structural insights from biferric model studies for peroxo bridged biferric enzyme intermediates.

Summary: Iron-based superconductors are magnetically ordered bad metals, with superconductivity appearing near a putative magnetic quantum critical point. The NaFe1-xCuxAs series provides a platform to investigate the connection between superconductivity, magnetism, and electronic correlations. By studying the valence state of Fe and spin dynamics in two NaFe1-xCuxAs compounds, it is concluded that the spin dynamics in NaFe0.53Cu0.47As arise from localized magnetic moments.

Summary: Resonant inelastic x-ray scattering (RIXS) was used to study epitaxial films of alpha-U3O8 and UN, with an incident energy tuned to the uranium N-4,N-5 absorption edges. The multiplets associated with a 5f(1) configuration were observed for U3O8, but the predicted strong transition at a transfer energy of 1.67 eV was not observed. For the 5f-itinerant system UN, no sharp transitions were observed, indicating a predominantly 5f(3) configuration in this band-like semi-metallic system. These findings provide important information on these materials and the potential of RIXS at the uranium N edge for actinide research.

Summary: This study investigates the electron-phonon coupling in high-Tc superconducting cuprates using resonant inelastic x-ray scattering. By comparing the results from two cuprate families at different doping levels, it is found that the EPC strength decreases with doping and shows a nonmonotonic trend at smaller momenta, which is attributed to the screening effect of charge carriers.

Summary: The electronic structure of GaTa4Se8 was investigated using density functional theory (DFT) with strong Coulomb correlations. It was found to be a Mott insulator, contradicting previous GGA band structure calculations. The t2g manifold split into a jeff=3/2 quartet and jeff=1/2 doublet due to strong spin-orbit coupling. The RIXS spectra at the Ta L2,3 edges were in good agreement with theoretical calculations. The dominant contribution in GaTa4Se8 is due to its unique crystal structure, which forms tetrahedral Ta4 clusters and exhibits strong Ta 5d- Se 4p hybridization with high density of states.

Summary: X-ray absorption and resonant inelastic x-ray scattering spectra of LaPt2Si2 single crystal at the Si 2p and La 4d edges reveal that the Si spectra are described in terms of Si s and d local partial density of states, while the La spectra are due to quasi-atomic local 4f excitations. Calculations show that Pt d-LPDOS dominates the occupied states, and a sharp localized La f state is found in the unoccupied states, in line with the observations.

Summary: In this article, a novel multichannel temporal attention-based network (MCTAN) is proposed for industrial health indicator prediction. The MCTAN utilizes channel attention and multi-head local attention mechanism to extract potential long-distance temporal relations. A weighted mean square error loss function is introduced to differently deal with early predictions and delay predictions. By combining data preprocessing and MCTAN, a framework is established to predict industrial health indicators through multichannel time series.

Summary: Chronic inflammation from bacterial infections hampers skin regeneration. Hypoxia in the infection microenvironment impairs the effectiveness of photodynamic therapy in phototherapy. To address this issue, a nanocatalytic hydrogel with enhanced phototherapy effects for antibacterial action and promoting skin regeneration is designed. The hydrogel consists of a polyvinyl alcohol scaffold, MXene/CuS bio-heterojunction, and polydopamine. The nanocatalytic hydrogel shows good antioxidant and antibacterial properties, and promotes capillary angiogenesis and collagen deposition, making it a promising approach for treating wound infections.

Summary: This study aimed to evaluate the predictive and prognostic value of the clinical characteristics of pulmonary large cell carcinoma (LCC) patients with synchronous brain metastases (SBM) at initial diagnosis using the SEER database. The results showed that patients under 60 years old or with bone metastases were more likely to have SBM at initial diagnosis. Age, T stage, bone metastases, and chemotherapy were identified as independent prognostic factors for overall survival (OS) in LCC patients with SBM. Surgery combined with chemotherapy and radiotherapy may provide the best survival benefit for highly selected patients.

Summary: Tumor immunotherapy aims to enhance CD8+ T cell killing of tumor cells, but the impact of tumor heterogeneity on tumor-immune interactions is not well understood. A cellular-level computational model was developed to investigate this. The model showed that the distribution of proliferating/quiescent tumor cells in a solid tumor mass changed with tumor evolution and influenced the suppressive functions of a tumor mass on T cells. Despite not fully inhibiting T cells, quiescent tumor cells had improved long-term survival due to their interior location. Overall, this model provides a useful framework for studying collective-targeted strategies in immunotherapy.

Summary: In this study, a protective film strategy was used to successfully construct a G-based hydrogel system with abundant TA as hydrogen bonds provider. The hydrogel system was first protected by a film formed from the chelation of SA and Ca2+, and then TA and Ca2+ were introduced using an immersion method. This strategy effectively protected the hydrogel structure and improved its mechanical and antioxidant properties. Cell experiments demonstrated that the G/SA-TA/Ca2+ hydrogels had good biocompatibility and promoted cell migration. Therefore, these hydrogels have potential applications in biomedical engineering, and the proposed strategy offers a new approach to enhance the properties of other protein-based hydrogels.

Summary: Photosensitized renoxification of HNO3 produces HONO in a high yield, which is an important source for atmospheric HONO. This study provides evidence of the direct formation of NO2* as a key intermediate during the photosensitizing renoxification of HNO3 using humic acid (HA) as a model environmental photosensitizer. The high HONO yield originates from the heterogeneous reaction of NO2* with co-adsorbed water molecules on HA. This work deepens our understanding of atmospheric HONO formation and the transformation of RNS.

Summary: In this study, a novel modification method based on the separator was proposed to inhibit the dendrite generation in rechargeable aqueous zinc-based batteries (AZBs). By uniformly spraying sonicated Ketjen black (KB) and zinc oxide nanoparticles (ZnO) on the separators, the electric field at the anode interface was homogenized by the highly conductive KB. The ZnO in the uniform KB conductive network provided sites for zinc deposition, reduced the by-products of the zinc anode electrode, and improved the electrochemical performance of AZBs.
