Summary: This study investigates the impacts of water molecules on methane adsorption in shale and finds that water molecules can modify the adsorption capacity, thermodynamics, and kinetics of methane adsorption. The presence of water molecules leads to a decrease in methane adsorption capacity, an increase in adsorption heat, a decrease in standard entropy, and a decrease in adsorption rate. This study also provides insights into methane adsorption in the three-dimensional network system of organic matter.

Summary: Despite the importance of metal-containing organic polymers in various modern applications, the controlled metallic loading remains poorly understood, limiting their rational design. By studying the binding properties of a soluble polymer made up of nine binding units, it was demonstrated that the site-binding model successfully predicts the binding properties based on the length of the polymeric chain. Furthermore, the examination of the photophysical properties showed impressive quantum yields for the europium-based red luminescence, which can be modulated by the chain length.

Summary: Different mechanisms of H-bond formation between sulfate anion and water are presented using molecular dynamics simulations. Multi-centered hydrogen bonds were observed, with hydrogen bridge making/breaking going according to the large angular jump mechanism. Classical, bifurcated and trifurcated hydrogen bonds between water and sulfate have transitional character, supported by free energies of binding of water to sulfate ion for particular types of hydrogen bridges. This phenomenon is similar to that observed in the hydration shell of perchlorate anion, although the amplitudes of angular jump and hydrogen bond lifetimes differ in both cases.

Summary: The study analyzed the properties of a carbon nanotube functionalized with short cytosine-rich fragments of ssDNA for the storage and controlled release of doxorubicin in response to pH changes. It was found that at neutral pH, doxorubicin molecules can be effectively intercalated between ssDNA fragments for storage, while at acidic pH, the molecules can be released due to structural changes in the ssDNA fragments.

Summary: The study found that carmustine can be stored in carbon nanotubes for a long time due to hydrophobic interactions. The access of water to carmustine can be controlled by the state of DNA fragments covalently bound to the nanotubes and the presence of doxorubicin molecules. Effective control of water access and decomposition of carmustine were observed when doxorubicin molecules corked the nanotube ends. The proposed molecular model can be useful in designing smart drug carriers for tumor microenvironments with reduced extracellular pH.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
