Summary: We studied the formation mechanism of lead carbonate (Pb3(CO3)2(OH)2) by laser ablation in ethanol under different atmospheres. We proposed that carbon dioxide (CO2) from the ambient atmosphere is converted into carbonate with the help of ethoxide anion produced during the ablation process. Our results from UV-Vis spectroscopy, after the addition of 2,4,6 trinitrotoluene to the ablated solution and subsequent reduction, supported this mechanism. We also found that carbonates can be obtained from metals and metal oxide sources, as demonstrated by the formation of hydrocerussite (Pb3(CO3)2(OH)2) and bismutite (Bi2O2(CO2)3) nanostructures.

Summary: Biochar, with its unique porous structure inherited from lignocellulose, was used as a carrier for small-size MgO materials to simplify the synthesis process and solve agglomeration and separation problems during adsorption. The preparation of biochar-supported MgO was done using the impregnation method. The properties of the obtained MgO varied under different synthesis conditions, and moderate pyrolysis conditions improved the Mg conversion rate. The capacity for Pb(II) adsorption was highly correlated with Mg content rather than specific surface area. Lowering the pyrolysis temperature or increasing the usage of the supporter improved adsorption efficiency when the Mg content was normalized.

Summary: A simple approach based on a flow system equipped with a novel 3D-printed Direct Injection Detector (DID) in an electrochemical mode is proposed for the simultaneous determination of cadmium and lead cations in water and food samples. This approach significantly reduces reagent usage and waste generation while increasing automation, fitting the principles of Green Analytical Chemistry. The use of flow DID combined with voltammetric detection using screen-printed carbon electrodes modified with carbonized halloysite and multi-walled carbon nanotubes demonstrated good linear response and low limits of detection.

Summary: This study investigates the storage behavior of multivalent ions on nanoporous carbons, comparing the capacitive performance of Mg ions with other charge carriers in different solvent systems. It is observed that the solvation and physisorption of Mg ions in nanopores have distinct effects on the oxidation stability of the solvent and the electrochemical performance of the supercapacitor. The use of ultramesoporous carbon as an active electrode material in a Mg ion-DME electrolyte system leads to high energy and power densities in a 4 V Mg ion supercapacitor.

Summary: This study synthesized 114 studies to quantify the ability of biochar in reducing greenhouse gas emissions in constructed wetlands. The results showed that biochar had a significant impact on CO2 mitigation, but not on CH4 and N2O. Several parameters, such as pyrolysis time, dissolved oxygen concentration, and hydraulic retention time, were found to influence the effectiveness of biochar in reducing CH4 emissions. Plant type and influent COD/TN ratio were important moderators for N2O emissions. Overall, this study provides important insights for estimating and improving the emission reduction benefits of biochar in constructed wetlands.

Summary: This study successfully synthesized MIL-53(Al) adsorbents through sonochemical-assisted synthesis and investigated their application in removing lead ions from aqueous solutions. The results showed that sonochemical-assisted synthesis could significantly reduce the synthesis time and increase the specific surface area of the adsorbents, thereby improving the mass transfer limitation in ion adsorption. The optimal conditions for lead ion removal were determined, and the applicability of adsorption equilibrium and kinetic models were verified. Furthermore, this study demonstrated the great potential of sonochemically synthesized MIL-53(Al) as an environmentally-friendly adsorbent for lead ion removal.

Summary: Polya was the first to introduce the concept of counting polynomials in chemistry. Although the characteristic polynomials of graphs have been extensively studied through quantitative methods to determine the molecular orbitals of unsaturated hydrocarbons, this field has not received much attention from chemists for several decades. Polynomials can be used to calculate various important topological indices, either explicitly or implicitly, including the related Theta, Omega, PI, and Sadhana polynomials. These polynomials play a significant role in computing the corresponding topological indices by considering the equidistant and non-equidistant edges of structural graphs. Topological indices are numerical values associated with networks that are used to predict chemical, physical, and biological activities. This article investigates the application of these polynomials in three classes of polycyclic aromatic hydrocarbons, including hexa-peri-hexabenzocoronene, hexa-cata-hexabenzocoronene, and dodeca-benzo-circumcoronene, and proposes closed formulas for the corresponding indices.

Summary: Diminished estimate techniques focus on image quality assessment by using partially retrieved features from the reference image. The goal is to create an objective evaluation method that can adapt to new visual distortions. This study proposes a rapid approach for quality assessment of color photographs by modifying the structural similarity index measure (SSIM) in a neutrosophic environment. The use of Single-Valued Neutrosophic Sets (SVNSs) and the construction of neutrosophic divergence show a correlation with SSIM and provide accurate information on image convergence and divergence. Additionally, a trustworthy Image Quality Assessment based on generalized exponential fuzzy entropy is proposed.

Summary: This study aimed to develop machine learning models to predict extubation failure in low birthweight neonates using a large dataset. Logistic regression and boosted-tree models were used, incorporating demographics, medications, and vital sign and ventilatory data. The best-performing model achieved an AUROC of 0.82, with birthweight, last FiO(2), average mean airway pressure, caffeine use, and gestational age as the most important features. These models can identify low birthweight ventilated neonates at risk for extubation failure. Validation across multiple centers is needed for generalizability.

Summary: The TiCN-HfN/TiCN-WC(THTW) laminated ceramics with different layer thickness ratio were prepared and studied for their residual stress, microstructure, and mechanical properties. Simulation results revealed alternating distribution of compressive and tensile stress layers, with decreasing residual compressive stress as layer thickness ratio increased. Cracks deflection and bridging, as well as the coexistence of transgranular and intergranular fractures, improved the comprehensive mechanical properties. The relative density and flexural strength initially increased and then decreased with increased layer thickness ratio. The hardness of TiCN-HfN layer first decreased and then increased, while fracture toughness decreased continually. Fracture toughness and Vickers hardness of TiCN-WC layer increased constantly. The laminated ceramic with a layer thickness ratio of 0.8 exhibited the best comprehensive mechanical properties, including a surface hardness of 16.93 +/- 0.30 GPa, surface fracture toughness of 7.91 +/- 0.12 MPa m1/2, flexural strength of 1293.54 +/- 10 MPa, and fracture toughness of 8.25 +/- 0.08 MPa m1/2.
