Summary: The discharge of crystal violet wastewater poses severe harm to the natural environment and human health due to its toxicity and carcinogenicity. The adsorption characteristics and mechanism of crystal violet on magnetic nanoparticles decorated bacteria were investigated, including the kinetic, equilibrium, mass transfer mechanism, and site energy distribution analysis. The results showed that Fe3O4 @bacteria had a high adsorption capacity for crystal violet, exhibited good recycling ability, and effectively reduced COD in dyeing wastewater. The adsorption process followed the Temkin isotherm and Elovich and pseudo-second-order kinetics models, and the mass transfer mechanism was described by the IPD model.

Summary: Attapulgite modified with 3-aminopropyltriethoxysilane shows promising potential as an adsorbent for removing anionic dyes such as Congo red from water. The adsorption behavior of Congo red onto the modified Attapulgite was best described by pseudo-second-order and Sips models. The modified Attapulgite exhibited higher adsorption capability for Congo red due to the presence of more high-energy sites, with adsorption being more favorable at high temperature and in acidic environments. Additionally, the hydrophobic surface of the modified Attapulgite reduced surface tension and electrostatic interactions played a crucial role in the adsorption process.

Summary: Competitive adsorption and complementary adsorption were observed in the adsorption of sulfamethoxazole (SMX) and bisphenol A (BPA) on magnetic biochar (MBC-1) with ferric chloride modification. The adsorption process involved different interactions such as pore filling, hydrophobic effect, 7C-7C EDA, hydrogen bonding, electrostatic force, surface coordination, and ion exchange. BPA had a competitive advantage due to its superior hydrophobicity, charge property, and molecular diameter, while SMX was removed mainly through hydrophobic interaction and hydrogen bonding. Complementary adsorption was confirmed as the two solutes occupied their preferred adsorption sites.

Summary: In this study, coal was used to prepare heterogeneous surfaces with both hydrophobic and hydrophilic constituents. The study focused on the adsorption of two frother surfactants, Methyl Isobutyl Carbinol (MIBC) and Dowfrother 250 (DF250), on coal surfaces with different Hydrophobic Index (HI). The results showed that both MIBC and DF250 could adsorb on coal surfaces through hydrophobic interactions, with different adsorption mechanisms leading to different orientations of the surfactants on the coal surfaces.

Summary: In practical applications, the chemical and physical adsorption of a polymer solution greatly affects its action mode and effect. Understanding the adsorption mechanism and its influencing factors can help to optimize the application mode and ensure application efficiency. Three types of polymer solutions were studied for their adsorption by a sorbent such as quartz sand, showing different adsorption characteristics and thicknesses. The influence of fluid motion on the adsorption capacity of the polymer solutions was examined, with optimization of injection rate identified as an effective method for controlling polymer applications in porous media.

Summary: This study investigated the adsorption behavior and mechanism of sulfamethoxazole (SMX) on a volcanic rock mineral adsorbent (VR) with Polypyrrole (PPy) modification. The results showed that pore filling and hydrogen bonding were the main adsorption mechanisms for SMX removal by VR, while electrostatic attraction, pi-pi electron donor-acceptor interaction (pi-pi EDA) and ion exchange explained the adsorption distinction between PPy supported VR (PPy-VR) and VR, indicating the wide pH application potential of the modified sorbent. Additionally, the energy distribution analysis revealed that PPy-VR exhibited a stronger adsorption affinity and energy heterogeneity for SMX due to the introduction of pi-pi EDA and ion exchange. The surface modification method provides a feasible idea for improving the application environment of adsorbents, and the analysis of site energy distribution promotes the understanding of the connection between site energy and adsorption mechanism.

Summary: Crystallisation is an important process in pharmaceutical industries for purifying active pharmaceutical ingredients. The randomness and variation in this process make it difficult to regulate and predict the yield from batch to batch. In this study, a new technique called dotted crystallisation was proposed, where carbon dots were used to control nucleation and crystallisation processes. By adding small quantities of carbon dots to a supersaturated solution of curcumin, the nucleation rate of curcumin can be regulated and improved, leading to smaller crystals with a narrow size distribution compared to conventional cooling crystallisation.

Summary: During crystal growth in impure solution, impurities can hinder the growth process and slow down or even stop crystal growth. In this study, we discovered that curcumin crystals can grow in impure solution containing similar impurities, following a non-classical crystallisation pathway. We found that at high impurity concentrations, crystals can grow through sympathetic nucleation, where new growth surfaces form on seed crystals. These new surfaces act as active growth surfaces and play a crucial role in determining the crystal growth kinetics, especially at lower supersaturations. Additionally, creating artificial macrosteps on the crystal surface can not only accelerate the crystallisation rate but also control impurity transfer into the bulk crystals.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
