Summary: In this study, the effects of gypsum and local organic waste as amendments to non-weathered bauxite residue (BR) were assessed. The addition of gypsum reduced the exchangeable sodium percentage (ESP), while the addition of organic waste had smaller effects on ESP. The leachate pH of the amended BR ranged from 8.7 to 9.4, while the pH of the unamended BR was 10.3. Gypsum and organic waste amendments improved the chemical properties of BR, but the rehabilitation goals for pH and ESP were not achieved.

Summary: This study provides a simple and cost-effective method for assessing the risks of organic pollutants in waste materials. The results showed little variability in dissolved organic carbon levels in primary sludges from different wastewater treatment plants, but significant differences in secondary sludges. Treated biosolids leached less dissolved organic carbon but had higher proportions of persistent or poorly biodegradable dissolved organic carbon.

Summary: In this study, magnetic Fe3O4@PDA nanocomposites decorated with silver nanoparticles (Ag NPs) were successfully synthesized. The Fe3O4 nanoparticles were modified by dopamine to form a poly dopamine (PDA) shell, which in-situ reduced silver ammonium ions to decorate Ag NPs on the surface. The resulting Fe3O4@PDA-Ag nanocomposites showed excellent catalytic activity, magnetic recyclability, and antimicrobial performance, making them a promising candidate for wastewater remediation.

Summary: Highly fluorescent carbon dots (TCDs) were synthesized using Tulsi Leaves and anchored on NiFe2O4 (NF) nanoparticles via a hydrothermal method, producing smart magnetically retrievable fluorescent nanohybrids (NFTCDs) for the first time. NFTCDs were capable of accurately detecting and efficiently degrading hazardous contaminants in aqueous samples through a photo-Fenton degradation mechanism. The NFTCDs-based platform demonstrated reliable quantification of toxic substances in real samples, with recyclability up to four cycles. This work presents a novel NFTCDs nanohybrid as an intelligent platform for synchronized monitoring and removal of deleterious contaminants, ensuring human safety.

Summary: This review provides an updated overview of the compounds isolated from the octocoral family Alcyoniidae that exhibit potential cytotoxic activity. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used to evaluate the bioactive compounds in vitro. The study found several compounds with stronger cytotoxicity than their positive control, and their mechanism of action remains to be investigated further.

Summary: Antineoplastic drugs, known for their severe toxic effects, require sensitive monitoring methods to address surface contaminations within preparation and administration units. An orthogonal normal phase analysis method has been developed to complement the limitations of the more common reversed-phase methods, and has shown promise in reliable relationship evaluation between chromatographic retention and chemical-structural features of the drugs under analysis.

Summary: The study found that 4-HBA was not present in the mixture when AOCA was prepared from CA, invalidating previous reports. Through TLC, UHPLC-MS/MS, UV-Vis, and ATR-FTIR analyses, the absence of 4-HBA in the mixture was confirmed. Principal components analysis of the ATR-FTIR spectral data established strong structural differences between 4-HBA and AOCA. While the antiviral effects of AOCA against HSV-2 were confirmed, a commercial sample of 4-HBA was completely inactive.

Summary: According to the 2021 World Drug Report, there are approximately 275 million drug users and 36 million people suffering from addiction worldwide, leading to a flourishing illicit drug market. In Italy, a significant number of people (30,083) were reported for violating the Italian Law D.P.R. 309/1990. However, the forensic laboratories in Italy face challenges in completing drug analyses quickly, causing delays in the reporting process for sentencing. To address this issue, a UHPLC-MS/MS-based platform was developed at the University of Milano-Bicocca, which enables law enforcement authorities to manage street seizures and generate accurate reports efficiently.

Summary: Low-cost photoactive hybrid materials for light management, based on neutral organic molecules intercalated into saponite, were prepared and characterized. TPBI was chosen as an organic host dye for its potential application as a downconverter in silicon or dye-sensitized photovoltaic modules. The neutral molecule was intercalated using a trojan horse approach, with the help of a cationic surfactant, to prevent aggregation. The obtained material was characterized using spectroscopic, diffractometric, and microscopic techniques. The intercalation, stability, and interactions of the dye were assessed by TGA-GC-MS. Finally, this material was used to prepare a photoactive polymer with desired optical properties.

Summary: Misuse of antibiotics has led to antimicrobial resistance, and using essential oils extracted from plants, such as thyme oil, in tablet form may be an effective and safe strategy to combat this problem. The inclusion of thyme oil in cyclodextrins enhances its efficacy and makes it more effective against biofilm-producing microorganisms. Moreover, this approach is environmentally friendly and cost-effective.

Summary: Membrane introduction mass spectrometry (MIMS) is a direct mass spectrometry technique that allows online monitoring and rapid quantification of trace levels of compounds in complex matrices without extensive sample preparation steps and chromatographic separation. It uses a thin, semi-permeable, and selective membrane to pre-concentrate analytes based on their physicochemical properties, and transfers them directly to the mass spectrometer using different acceptor phases.

Summary: In this study, two copolymers were thermally grafted from melt to a silicon wafer, and it was observed that the lower molecular weight component of the blend preferentially grafted to the polymeric brush layer. The enrichment of short chains in the brush layer was found to be independent of time. Molecular dynamics simulations supported this observation, providing insights for further investigation and control of brush layer characteristics.
