Summary: In this study, mesoporous polydopamine (mPDA) encapsulation of fluorescent nanodiamonds (FNDs) was demonstrated for efficient functionalization. The mPDA shell could be easily modified with different functional groups such as thiol-terminated methoxy polyethylene glycol (mPEG-SH), hyperbranched polyglycerol (HPG), and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS). The modified PEGylated FND@mPDA particles showed efficient cellular uptake and served as a fluorescent imaging probe for HeLa cells. Moreover, HPG-functionalized FND@mPDA was used for microRNA detection via hybridization, while the increased surface area of the mPDA shell allowed efficient loading of doxorubicin hydrochloride and its enhanced delivery with TPGS modification, resulting in high toxicity to cancer cells.

Summary: This paper analyzes the adsorption of amoxicillin (AMX) and doripenem (DRPNM) on copper benzene-1,3,5-tricarboxylate (HKUST-1) in single and binary systems. The experimental results show a reduction in adsorption capacities in binary solutions compared to single solutions. The modeling results explain this reduction as a competitive effect between the adsorbates. The statistical physics model and DFT simulations provide insights into the adsorption mechanisms and intermolecular interactions. Overall, this paper presents a new explanation of the adsorption mechanism of these antibiotics on HKUST-1 MOF, combining experimental results and theoretical approaches.

Summary: Struvite precipitation and reuse from phosphorus-rich wastewater is a cost-effective measure to improve phosphorus utilization efficiency and decrease environmental impact. However, the presence of antibiotics in recovered struvite can spread antibiotic resistance genes, making it ecologically unsafe. This review investigates the effects of antibiotics on struvite precipitation, discussing pH, dissolved organic matter, and suspended solids, and analyzing possible solutions for minimizing antibiotics. It concludes that pH change and dissolved organic matter have a significant influence on antibiotic residue in struvite, and calls for the development of more efficient technology to ensure the ecological safety of recovered struvite.

Summary: This study explored the potential of polydopamine-modified salecan hydrogel (PMSH) for removing antibiotics from water. The addition of polydopamine improved the physical properties of PMSH and enhanced its antibiotic adsorption capacity. PMSH3 demonstrated fast adsorption kinetics and high adsorption capacities for chlorhexidine acetate, minocycline, and erythrocin. The adsorption process was found to be chemical, and the adsorption of antibiotics on PMSH3 was multilayer. The regenerated antibiotics showed strong antimicrobial properties against Staphylococcus aureus and Escherichia coli.

Summary: This study used the Fenton immersion method to simulate the weathering process of microplastics and examined their behavior with hydrophilic antibiotics. The weathered polystyrene was found to have decreased crystallinity, increased oxygen-containing functional groups, and surface cracks, making it more susceptible to weathering. Additionally, the rougher and more hydrophilic surface of the weathered particles facilitated the adsorption of hydrophilic antibiotics. The adsorption behavior was influenced by factors such as ionic strength and pH. Overall, this research provides important insights into the weathering process and ultimate fate of microplastics.

Summary: Hyaluronic acid shows potential as a coating to improve the biocompatibility of nanodiamond-antibiotic composites. The adsorption of hyaluronic acid is found to be higher on nanodiamonds with initially negative zeta-potential, after pre-adsorption of Miramistin, but still lower than on positively charged nanodiamonds unaffected by Miramistin. The maximum adsorption of hyaluronic acid is observed when Miramistin neutralizes the surface charge of nanoparticles.

Summary: This study investigated the development of submicron and nanocrystalline silicate materials with MFI structure in a fluorinated surfactant medium, using perfluorononanoic acid as an example. It was found that the crystal structure of the zeolite framework formed slower in fluorinated surfactants due to the presence of aluminum atoms. The fractions of Bronsted and Lewis acid sites in the synthesized zeolites were independent of the amount of aluminum introduced. Moreover, the synthesized zeolites with lower concentration of Bronsted acid sites and smaller crystal size showed similar activity and operational stability to commercially available catalysts in the oligomerization of light alkenes.

Summary: Supported catalysts Mo/Al2O3 modified with (NH4)(2)SiF6 and H3BO3 were synthesized and tested for the metathesis of propylene. The support modifications had different effects on the catalyst acidity, with (NH4)(2)SiF6 not altering it while the interaction with boric acid increased the acidity. Dual modification with both (NH4)(2)SiF6 and H3BO3 enhanced the catalyst activity but led to faster deactivation.

Summary: In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids were obtained. These compositions were characterized and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. The acidity change is non-linearly influenced by the amount of heteropolyacid (HPA), and the removal of sulfur-containing compounds is correlated with the concentration of Bronsted acid sites on the catalyst surface. On the other hand, the removal of pyridine is primarily determined by the content of heteropolyacids in the catalyst.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
