Morphology Effect of FeWO Boosting Efficiency of Photocatalytic Uranium Extraction under Visible Light and Mechanism Investigation.

Wolframite (FeWO) is a type of polyoxometalate known for its high chemical stability and electronic properties, which makes it an excellent photocatalyst. While FeWO has been widely utilized in the domain of organic catalysis, there are currently no documented reports regarding its use in the degradation of U(VI). In this study, the effect of changing the microscopic morphology of the FeWO catalyst to enhance its photocatalytic activity was explored.

Revisiting face forgery detection towards generalization.

Face forgery detection aims to distinguish AI generated fake faces with real faces. With the rapid development of face forgery creation algorithms, a large number of generative models have been proposed, which gradually reduce the local distortion phenomenon or the specific frequency traces in these models. At the same time, in the process of face data compression and transmission, distortion phenomenon and specific frequency cues could be eliminated, which brings severe challenges to the performance and generalization ability of face forgery detection.

Artesunate attenuates skin hypertrophic scar formation by inhibiting fibroblast activation and EndMT of vascular endothelial cells.

Background Hypertrophic scarring is an abnormal condition involving excessive fibroblast activation, aberrant extracellular matrix deposition, and persistent inflammation. Current treatments have limited efficacy and potential adverse effects, necessitating the development of new approaches. Purpose In this study, we investigated the effects of artesunate (ART) on hypertrophic scar (HS) formation and explored the underlying cellular and molecular mechanisms.

In Situ High Selectivity Contact-Electroreduction of CO2 to Methanol Using an Imine-Mediated Metal-Free Vitrimer Catalyst.

Metal catalysts for CO2 reduction reaction (CO2RR) face challenges such as high cost, limited durability and environmental impact. Although various diverse and functional metal-free catalysts have been developed, they often suffer from slow kinetics, low selectivity, and non-recyclability, significantly limiting their practical applications. In this study, we introduce a recyclable non-metallic polymer material (vitrimer) for a new platform in contact-electro-catalysis.

Synergistic Effect of Solvent and Component Engineering for High-Efficiency Carbon-Based Perovskite Solar Cells.

It is highly desired to get rid of the high-temperature annealing process in manufacturing perovskite solar cells (PSCs) to reduce production costs. Herein, perovskite films are designed by rapidly evaporating of a mixture solvent consisting of methylamine ethanol solution (MA-EtOH sol) and acetonitrile (ACN) (MA-EtOH-ACN) by dopping different amounts of formamidinium iodide (FAI) into the CHNHPbI (MAPbI) precursor solution; as a result, the high-temperature annealing step is effectively eliminated while the perovskite solar cell efficiency remains unchanged. The in situ UV-vis absorption for monitoring the perovskite crystallization process shows that FAI retards the crystallization rate, leading to a dense and smooth film.

Improving Adversarial Training from the Perspective of Class-Flipping Distribution.

Adversarial training has been proposed and widely recognized as a very effective method to defend against adversarial noise. However, the label flipping pattern on different classes still need deeper exploration to identify potential problems and assist in further enhancing robustness. In this work, we model the class-flipping distribution via statistical investigations and find this distribution reveals two shortcomings: the highly misleading category is present in the model's predictions for data in each class, and the trend in class flipping are significantly different across classes.

Target High-Efficient Ethylene Production from Dilute CO Enabled by Sustainable Contact Electrons.

The electrochemical CO reduction reaction (CORR) exhibits significant potential to efficiently convert CO into ethylene (CH). However, achieving high CH selectivity remains a considerable challenge due to the difficulty in effective C─C coupling and stringent requirements on CO purity. Herein, a novel contact-electro-catalysis method for CORR is presented by constructing dual-active-site catalysts on the electronegative tribolayer of a triboelectric nanogenerator (TENG), including single copper atom anchored polymeric carbon nitride (Cu─PCN) and CuO nanoparticle, achieving an outstanding CH Faradaic efficiency of 63.

However, traditional nanofibrous membranes, made from petroleum-based synthetic polymers, pose significant environmental concerns due to their non-biodegradability and reliance on fossil resources.

Enhanced Optical Modulation Properties via Two-step Annealing of Sol-Gel Deposited Vanadium Dioxide Thin Films.

Vanadium dioxide (VO) is a key coating component for smart devices, especially in smart windows, due to its excellent thermochromic properties and metal-insulating transformation. In this study, we investigate the influence of different annealing on the VO thin films prepared by a sol-gel technique combined with spin-coating and compare the changes in morphology, structure, and optical properties. Of the two types of VO (M) films obtained by one-step annealing at 700 °C and two-step annealing at 500 and 700 °C, the two-step annealed samples formed an intermediate phase VO (B), which allowed them to exhibit higher purity and better crystallinity than those of the one-step annealed samples.

Goose Deoxycholic Acid Ameliorates Liver Injury in Laying Hens with Fatty Liver Hemorrhage Syndrome by Inhibiting the Inflammatory Response.

Fatty liver hemorrhagic syndrome (FLHS) in laying hens is a nutritional and metabolic disease involving liver enlargement, hepatic steatosis, and hepatic hemorrhage as the primary symptoms. The syndrome is prone to occur during the peak laying period of laying hens, which has resulted in significant economic losses in the laying hen breeding industry; however, the specific pathogenesis of FLHS remains unclear. Our group and previous studies have shown that bile acid levels are significantly decreased during the development of fatty liver and that targeted activation of bile acid-related signaling pathways is beneficial for preventing and treating fatty liver.

Transition-metal nitrides (TMNs) have garnered considerable attention for energy conversion applications owing to their exceptional electronic structures and high catalytic activities. However, the scarcity of active sites in TMNs impedes their large-scale application. This study describes the use of wetness impregnation and ionic-liquid methods to enhance the electrocatalytic efficiency of molybdenum nitride (MoN) atomic clusters finely dispersed on nitrogen-doped carbon (MoN@NC) substrates.

Synchronous nitrogen and sulfur removal in sulfur-coated iron carbon micro-electrolytic fillers: Exploring the synergy between sulfur autotrophic denitrification and iron-carbon micro-electrolysis.

Sulfur autotrophic denitrification (SAD) is a promising technology for nitrogen removal, particularly suitable for low carbon-to-nitrogen wastewater without additional carbon sources. However, SAD inevitably generates significant amounts of SO. To address this issue, combining SAD with iron-carbon micro-electrolysis technology, which can reduce sulfate, provides electron donors for autotrophic denitrification and facilitates sulfur cycling.

AI-directed formulation strategy design initiates rational drug development.
