Summary: Given the large amount of harmful pharmaceuticals being released into the water stream, it is crucial to eradicate or reduce these chemicals to a minimum permissible limit. This study reports the fabrication of a magnetic guar gum graphene oxide nano-composite (mGG/GO NC) for the adsorption of ciprofloxacin from wastewater. Various techniques were used to characterize the guar gum and the nanocomposite, and it was found that the adsorption process followed the pseudo second order model and Langmuir isotherm model. The nanocomposite exhibited high adsorption capacity and recyclability, potentially due to a synergistic effect of multiple interactions in the adsorption mechanism.

Summary: This research focuses on blackberry leaf extract (BLE) as an environmentally friendly corrosion inhibitor for copper in 0.5 M NaCl. High-performance liquid chromatography (HPLC-DAD) was used to identify caffeic acid, quercetin-3-O-glucoside, and kaempferol-3-Oglucoside in BLE. The functional groups of BLE were identified using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). Electrochemical methods, including potentiodynamic polarization, electrochemical frequency modulation, and electrochemical impedance spectroscopy, show that BLE acts as a mixed type inhibitor with a maximum inhibition efficiency (IE) of 97.19%. The corrosion process is controlled by diffusion when BLE concentration is lower than 15 g/L, and by charge transfer at 15 g/L BLE.

Summary: We have developed an electrochemical advanced oxidation process for the removal of ethidium bromide (1), using Eu-doped MnWO4 (Eu:MnWO4) obtained through a template-driven synthesis, along with a suitable monitoring method. The Eu:MnWO4-coated graphite electrode serves as an anode under galvanostatic conditions, effectively removing 1. We have also introduced a modified carbon paste electrode for monitoring 1 with a detection limit of 54 nM. The developed method shows promising potential for catalytic treatment and process monitoring of 1-polluted waters.

Summary: This study proposes Pickering emulsions based on wax and halloysite clay nanotubes for coating silk sutures to increase their loading capacity towards eosin. The presence of halloysite/wax microspheres on the surface of silk sutures has also been explored for controlled release of hydrophobic drugs. The influence of the coating on the thermal and mechanical properties of the sutures has been studied using various techniques. In conclusion, the wax/halloysite Pickering emulsions can successfully generate hydrophobic microdomains on the surface of silk sutures, leading to enhanced flexibility and improved loading capacity towards eosin.

Summary: Operational problems in the oil industry caused by the precipitation of paraffins can be prevented by using polymeric additives. This article evaluates the use of polymeric nanocomposites as pour point reducers in different types of crude oil and finds that they are more efficient than pure poly(ethylene-covinyl acetate) (EVA) in reducing the pour point. The nanocomposites also modify the wax crystals and reduce the viscosity of the oil samples.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Chitosan-Pd0 nano particles encapsulated in Al, Co-pillared montmorillonite nanocomposites were successfully synthesized using a facile one-pot heat treatment method. The Al, Co pillaring effectively expanded the surface area and generated numerous mesopores in the interlayer space of the MMt. The resultant nanocomposite exhibited similar high comprehensive catalytic performances as the one prepared by the regular divided-multistep method. The encapsulation of CS chains and doping of Co in the Al pillaring also contributed to the improved catalytic performance.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.

Summary: The interaction between talc and the depressor CMC was investigated through molecular dynamics simulation and density functional theory calculation. It was found that CMC showed stronger adsorption on the edge plane of talc due to enhanced interactions with polar groups and water molecules. The study also revealed specific interactions between H atoms in CMC and O atoms in the edge plane, as well as between O atoms in CMC and Si, Mg atoms in the edge plane. Hydration shells on the basal and edge planes of talc were examined to explain the phenomenon.
