Summary: The biosorption of uranium by non-living biomass of Chlorella sorokiniana was studied. The optimal pH for uranium biosorption was 2.5 and the equilibrium time was 90 min. The kinetics followed a pseudo-second-order rate equation and the biosorption process fit the Langmuir isotherm model well. The morphology of the algal biomass and functional groups on the algal surface were investigated. Thermodynamic simulations indicated that the uranium biosorption process was exothermic and spontaneous at lower temperatures.

Summary: Adsorptive separation techniques are more energy efficient than conventional thermal separation techniques such as distillation. However, the use of adsorption techniques for the separation of multicomponent liquid mixtures is still limited due to the lack of accurate adsorption thermodynamic models. In this study, the surface excess of adsorption for six binary liquid mixtures on silica gel was rigorously computed using the frameworks of the generalized Langmuir isotherm and the adsorbed solution theory.

Summary: The FH isotherm, which was first introduced in the mid-2000s in the field of water contaminant adsorption, has gained significant attention in recent years, largely due to its coverage in review articles. This article highlights the incompatibility of the linear form of the FH isotherm with its original nonlinear version. The study shows that the linearized FH isotherm suffers from serious defects, including incorrect parameter estimates and the inability to plot standard isotherm curves. It is recommended to use the original form of the FH isotherm in data fitting to avoid publishing meaningless research. Additionally, the article presents a novel application of the FH isotherm to evaluate the energy distribution of heterogeneous adsorbents.

Summary: This study investigated the effects of glyphosate (GPS) herbicides on the adsorption of uranium using goethite as a model soil mineral. The presence of GPS increased the adsorption capacity of goethite for uranium. The adsorption kinetics followed a quasi second-order model and the adsorption process could be described by Langmuir isotherm. FTIR and XPS analysis provided additional evidence for the uptake mechanism.

Summary: The study investigates the simultaneous adsorption of paracetamol and nimesulide using activated carbon, revealing a displacement phenomenon where nimesulide molecules replace active sites previously occupied by paracetamol. The higher affinity between AC and nimesulide is attributed to the more hydrophobic nature of nimesulide. The thermodynamic analysis suggests exothermic, favorable, and spontaneous adsorption with low adsorption energies supporting physisorption.

Summary: In this study, nitrogen-doped carbon quantum dots (N-CQDs), N-F codoped carbon quantum dots (CQDs), and N-S codoped CQDs were synthesized using three different methods, including electrochemical, solvothermal, and pyrolysis, with monoethanolamine and citric acid precursors. Ammonium fluoride and/or thiourea were used as the precursors for the second dopant. Factors affecting the synthesis parameters were examined to optimize the absorption edge and reduce the band gap in UV-visible spectroscopy. The best results were obtained with the pyrolysis method, which yielded N-F/CQDs with the highest absorption edge of 650 nm, a band gap of 1.91 eV, and a particle size of 24 +/- 7 nm. X-ray photoelectron spectroscopy (XPS) analysis confirmed the simultaneous doping of F and N atoms in the CQDs structure, and photoluminescence (PL) analysis revealed excitation-dependent properties suitable for optical sensor and solar cell applications.

Summary: Nitrogen-fluorine codoped graphene quantum dots (N, F-GQDs) were synthesized through a one-pot hydrothermal method using glucose and ammonium fluoride (AF). The composition of nitrogen and fluorine with GQDs by AF was optimized to approach the highest light absorption edge in UV- visible spectroscopy and receive upconversion properties in photoluminescence (PL) analysis. The best cell with N, F-GQD0.07/TiO2/ FTO photoanode improved the efficiency, open circuit voltage, and short circuit current density, from 0.07 to 0.51, 370 to 699 mV, and 0.3 to 1.2 mA/cm2, respectively, compared to the cell fabricated by the blank TiO2/FTO photoanode.

Summary: In this study, non-catalytic co-pyrolysis of petroleum vacuum residue (VR) and polypropylene (PP) was conducted in a batch condition under CO2 and/or steam atmospheres. Statistical analysis showed that CO2 + steam environment was more effective in reducing asphaltene formation and suppressing coke formation. The addition of PP improved the yield and quality of the liquid product and reduced the coke content. Optimum conditions for the pyrolysis reaction were determined, resulting in high maltene yield, reduction of asphaltene and coke, and improved quality of the upgraded oil. The pyrolysis of VR with PP in the CO2 + steam environment was considered an economically viable and environmentally friendly technique for transforming low-grade VR feedstocks to valuable liquid fuels without using catalysts.

Summary: Mesoporous carbon-nitrogen doped ZnO powders were synthesized from ZIF-8 through thermal decomposition under nitrogen and air atmospheres. The prepared material exhibited significant photocatalytic activity for acetaldehyde degradation under visible light irradiation. The optical and morphological properties of the samples were characterized, and the results showed that the absorption edge of the prepared samples was shifted to the visible range. The photocatalytic activity of the samples was much higher than that of the bare ZIF-8 and commercial ZnO powder. The sample prepared by N2 thermal decomposition of ZIF-8 at 600 degrees C for 120 min, followed by air annealing at 450 degrees C for 90 min, achieved a removal rate of about 90% for acetaldehyde.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
