Facet-dependent Heterogeneous Fenton Reaction Mechanisms on Hematite Nanoparticles for (Photo)catalytic Degradation of Organic Dyes.

Although heterogeneous photo-Fenton reactions on nanoparticulate iron oxides effectively degrade organic pollutants, the underlying surface mechanisms remain debated. Here, we demonstrate how these pathways are modulated by specific hematite crystal facets. To investigate the influence of particle surface structure, methylene blue (MB) adsorption and photodegradation kinetics are examined using facet-engineered hematite nanoparticles with distinct exposed facets.

High Social Motivation Can Promote Time-Based Prospective Memory Performance.

Prospective memory, the ability to remember to execute a preplanned activity, is important in social interactions, insofar as such interactions frequently involve preplanned activities. The importance of prospective memory varies across different social contexts and individuals generally make greater efforts to ensure the completion of prospective memory tasks under high social motivation conditions compared to low social motivation conditions. We aimed to investigate the effects of various levels of social motivation on prospective memory.

Rapid Screening of Single-Atom Catalyst Synthesis Conditions Using ToF-SIMS and Facet-Dependent Single-Crystal Substrates.

Single-atom catalysts (SACs) offer superior catalytic performance compared with traditional nanoparticle catalysts but are challenging to develop because of the need for extensive optimization and specialized characterization techniques. This study presents a rapid and versatile method for detecting synthesis conditions and elucidating the deposition mechanisms of SACs on various substrates. By depositing active elements (Au, Cu, Ni, and Rh) on facet-specific single-crystalline substrates (CeO, TiO, MgO, and AlO) and employing time-of-flight secondary ion mass spectroscopy (ToF-SIMS), we assessed facet-dependent deposition behaviors and identified optimal conditions for solution-based SAC synthesis.

In this study, we compiled a comprehensive dataset encompassing 3543 hybrid plants and their parental species across 274 geographical regions.

Achieving Extra-High-Quality Images in ToF-SIMS Molecular Imaging of Insulating Samples Using a Low Current O Auxiliary Beam and Back Side Au Coating.

Molecular imaging enabled by ToF-SIMS has become increasingly desirable in many research fields in the last several decades. However, complex charging on highly insulating samples and at phase-separation boundaries may lead to dark edges and boundaries in ion images, presenting a big obstacle to obtaining high quality ion images, even with low energy electron charge compensation. Depositing a thin metal layer on the sample surface or using a combination of a low energy electron beam and a low energy Argon ion beam can be helpful.

Responding to News Sensitively in Stock Attention Networks via Prompt-Adaptive Trimodal Model.

Modern quantitative finance and portfolio-based investment hinge on multimedia news and historical price trends for stock movement prediction. However, prior studies overlook the long tail effect in the feature distribution of stocks, inevitably leading to biased attention and thus degrading the efficiency of utilizing news. To this end, we propose a prompt-adaptive trimodal model (PA-TMM) to overcome the biased stock attention networks and tail feature scarcity problem.

Spectral Analysis for Photon Emission of Rare-Earth Ions in Single Plasmonic Hot Spot.

Rare earth ion luminescent materials have attracted extensive attention due to their wide applications in biochemical sensing and bioimaging. However, the low quantum yield and weak luminescence intensity have restricted their further development. Realizing the modulation of rare-earth ions' emission behavior has become a hot topic in the interdisciplinary fields of materials and chemometrics.

Ambusher in sponge: a new species of (Annelida, Eunicidae) commensal within deep-sea Farreidae (Porifera, Hexactinellida) on northwest Pacific seamounts.

Deep-sea sponges create complex biogenic structures and attract a wide array of deep-sea organisms, including symbionts. In this study, we describe , a new eunicid species living in the central cavity of deep-sea farreid glass sponges found on northwest Pacific seamounts. The new species closely resembles the Atlantic both morphologically and molecularly, but it differs in the relative length of palp compared to peristomium, starting points of subacicular hooks, and shape of pectinate chaetae.

IGF2BPs-regulated TIN2 confers the malignant biological behaviors of gastric cancer cells.

Background: Telomere maintenance is an important feature of tumor cells. Telomeric-repeat binding factor 1 interaction nuclear protein 2 (TIN2), a key member of the shelterin proteins, functions in regulating telomere structure, length and function. Our work sought to investigate the role of TIN2 in controlling gastric cancer (GC) malignant biological behaviors.

Chemical Differences in Environmental Films Collected on Surfaces with Different Hydrophilicity.

Environmental films form when airborne particles and molecular species adsorb on solid surfaces. Recent studies have characterized these films but overlook how collection methods and host-surface character (orientation, chemical functionality, or height) change the deposition process. In this work, environmental films are collected at a rural location on gold and silicon surfaces (water contact angles of ca.

Cascading Failure in Cyber-Physical Systems: A Review on Failure Modeling and Vulnerability Analysis.

Cascading failures pose a significant security threat to networked systems, with recent global incidents underscoring their destructive potential. The security threat of cascading failures has always existed, but the evolution of cyber-physical systems (CPSs) has introduced novel dimensions to cascading failures, intensifying their threats owing to the intricate fusion of cyber and physical domains. Addressing these threats requires a nuanced understanding achieved through failure modeling and vulnerability analysis.

Enhanced CH/N Separation Efficiency of UiO-66-Br through Hybridization with Mesoporous Silica.

Efficient separation of CH from N is essential for the purification of methane from nitrogen. In order to address this problem, composite materials consisting of rod-shaped SBA-15-based UiO-66-Br were synthesized for the purpose of separating a CH/N mixture.
