N-Acetyl-L-cysteine-grafted metal-organic framework for heavy metal removal from hazardous waste Over the past century, industrial development has led to severe environmental problems, including the contamination of wastewater (such as from rivers and seas) with dissolved heavy metals (e.g., Pb2+ and Cd2+), which pose serious health risks. To remove these heavy metals, heterogeneous solid-state adsorbents, such as metal-organic frameworks (MOFs) have attracted significant attention due to their porous extended structures, strong binding sites, ease of separation from water, and non-toxic, stable nature. In this work, we functionalized MOF-808 with N-acetyl-L-cysteine (AcC), which contains soft-base –SH groups capable of binding soft-acid metal ions (Pb2+ and Cd2+), via grafting onto the Zr6 metal nodes. Approximately 83% of the Zr6 nodes in MOF-808 were successfully functionalized with AcC, yielding AcC@MOF-808. This modification enabled strong interactions between the AcC groups and heavy metals, consistent with hard-soft acid-base (HSAB) theory, while maintaining the crystallinity and availability of free –SH sites. As a result, AcC@MOF-808 demonstrated highly efficient capture of Pb2+ and Cd2+, facilitated by the thiol groups along with the aliphatic and acetyl functionalities that enhance adsorption efficiency, as confirmed by crystallographic, spectroscopic, and microscopic analyses. The maximum adsorption capacities for Pb2+ and Cd2+ were 231 mg g−1 and 109 mg g−1. AcC@MOF-808 achieved 99% removal of both Pb2+ and Cd2+ from 10 ppm trace metal solutions, exhibiting particularly rapid uptake (within seven minutes). The corresponding rate constant (k) values were 6.6×103 g mg−1 min−1 for Pb2+ and 1.1×103 g mg−1 min−1 for Cd2+, and adsorption kinetics that followed a pseudo-second order model. Furthermore, AcC@MOF-808 showed high selectivity toward Pb2+ and Cd2+ over other divalent metal ions, including both alkali and transition metals, demonstrating its strong potential for heavy metal removal from real wastewater systems.

Design and Synthesis of Holu‐7, a Quinazolinone Derivative With an Active Stereo Geometry and Polar 2,4‐Dihydroxyphenyl Group, as a Selective Anticancer Agent Quinazolin-4-one scaffolds offer rich anticancer chemistry but often trade potency for selectivity. Building on a tubulin-targeting lead (MJ-65), 12 new derivatives (26-37) were synthesized to dissect geometry-activity relationships and enhance the polarity of C2-substituents. Cytotoxicity was profiled against cancerous (HCT116 and CAL27) and normal (FHC) cells. In silico studies employed CDOCKER against tubulin (PDB 5NJH), GROMACS for molecular dynamics (MD), and ProTox-3.0 for toxicity estimation. The previously synthesized geometry-matched pairs 21-25 were active at 10 μM. In contrast, their isomers 26-30 were largely inactive, revealing a configuration-dependent binding mechanism. Optimizing polarity yielded Holu-7 (compound 35; 2,4-dihydroxyphenyl at the C2-position), which exhibited sub-50 nM IC<sub>50</sub> in HCT116/CAL27 cells and > 10 μM in FHC cells and induced robust G<sub>2</sub>/M arrest. Docking/MD supported stable vinca-site engagement, with hydrogen bonds to ASP179/ASN206 and π-stacking with TYR224. ProTox-3.0 predicted a higher LD<sub>50</sub> and absence of major organ toxicities relative to MJ-65. This data indicates that configuration-aware, polarity-tuned design can deliver selective quinazolinone anticancer candidates; therefore, Holu-7 merits further preclinical evaluation.

Production and Characterization of Bacterial Cellulose from Traditional Homemade Vinegar: Overview of Biotechnological Applications Cellulose is a polymer that can be produced not only by plants but also by some bacteria. The gelatinous layer known as "mother of vinegar" is an example of bacterial cellulose (BC), which is formed on the surface during the process of traditional homemade vinegar fermentation. In this study, bacterial cellulose isolated from homemade vinegar produced by the traditional method was produced, and the resulting polymer was characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). FTIR analysis demonstrated that the chemical bonding of the obtained bacterial cellulose is characteristic of cellulose. The presence of typical peaks, including a broad -OH stretching band (~3340 cm-1) and an aliphatic C-H stretching band (~2890 cm-1), was observed. Scanning electron microscopy (SEM) images revealed that the bacterial cellulose exhibited a nanofibrous network structure with elevated porosity. The characterization results show that bacterial cellulose exhibits high water retention capacity and mechanical strength due to its pure, fibrous nanostructure. It is clear that bacterial cellulose has many advantages. Specifically, its potential applications include the fields of biomedical research, namely in the domains of wound dressings, tissue scaffolds and controlled drug release. Additionally, its relevance extends to food science, which can be employed as a low-calorie food ingredient, a texturing agent or a coating material. In conclusion, it has been demonstrated that bacterial cellulose derived from traditional fermentation products, such as homemade vinegar, can be utilized as a high-value-added biomaterial. With these superior properties, bacterial cellulose has potential applications in biomedical fields (particularly wound dressings, tissue scaffolds and controlled drug delivery) and food applications (low-calorie food ingredient, texture and coating material).

Complete Suppression of Color Dispersion in Quantum-Dot Backlights by Optimizing Optical Configuration of Films This study investigated the optimization of optical film configurations to mitigate angular color deviation—a persistent challenge in quantum dot (QD) backlight displays. A white backlight was implemented by placing a yellow CdSe-based QD film on a blue edge-lit backlight, followed by various combinations of prism and diffusion films. Optical characteristics, including luminance, spectral distribution, and chromaticity coordinates, were systematically measured over a viewing-angle range of −70° to 70° for different film arrangements. Applying one or two prism films significantly enhanced normal luminance and improved color conversion efficiency by forming vertical optical cavities; however, this also introduced the side-lobe phenomenon, leading to color non-uniformity. Placing a diffusion film between the QD and prism films did not resolve these issues, whereas positioning it as the topmost layer above the prism films effectively eliminated color dispersion and produced a uniform luminance distribution. These results provide practical design guidelines for optimizing optical film stacks in QD-enhanced backlight units to achieve superior color uniformity in LCD displays.

LASER INFORMATION SYSTEM FOR MONITORING GLUE EVAPORATION DURING DRYING In the context of advancing technologies in printing, materials processing, and chemical production, there is a growing demand for precision in monitoring volatile emissions generated during drying processes. Conventional control methods often lack the speed, sensitivity, or selectivity required for real-time analysis of adhesive evaporation products, particularly in dynamic industrial environments such as book block drying chambers. This study substantiates the development of laser-based resonance photometric systems for evaluating the concentration of evaporated chemical components from adhesive mixtures. A methodological framework is proposed for implementing dual-channel laser photometry, enabling non-contact, rapid, and spatially resolved assessment of volatile content. The structure and operating principles of a laboratory-grade concentration meter are presented, incorporating semiconductor lasers, photodetectors, signal processing units, and intelligent control agents. Special attention is given to the physical and quantum-chemical interactions of laser beams with aqueous media, as well as to the solubility dynamics of adhesive components under thermal influence. A two-stage selective photoionization approach is introduced to enhance signal amplification through resonance effects, enabling more precise quantification of emissions. The proposed methods can be applied not only to printing production environments but also to broader ecological monitoring tasks involving laser-based diagnostics of airborne and liquid-phase contaminants. These technologies contribute to the development of next-generation intelligent sensing systems capable of supporting environmental safety and process optimization.

Influence of Pre-Mechanical Exfoliation on the Synthesis of Reduced Graphene Oxide via the Hummers Method This study investigates the effects of mechanical pre-exfoliation on the synthesis of reduced graphene oxide (rGO) via the Hummers method, employing a hybrid approach that combines thermal and mechanical pretreatments. Initially, graphite was subjected to thermal expansion at 900 °C for 15 minutes to increase the interlayer spacing. The expanded material was then processed using ball milling in the presence of sulfuric acid (H₂SO₄) for varying durations (12, 24, and 48 hours) to assess the influence of milling time on the efficiency of subsequent oxidation and reduction steps. Following the mechanical treatment, the samples were oxidized using the conventional Hummers method and reduced chemically with ascorbic acid to obtain rGO. The resulting materials were characterized using techniques such as X-ray diffraction (XRD), to analyze variations in interplanar spacing and distinguish between graphite and rGO; Raman spectroscopy, to investigate structural features and provide detailed insights into the quality of graphene and its derivatives; and scanning electron microscopy (SEM), for morphological analysis. The results demonstrate that the combination of thermal and mechanical pretreatments significantly influences the structural and morphological properties of the final material, enhancing exfoliation efficiency and improving performance during oxidation. This hybrid approach appears to be a promising strategy for optimizing scalable synthetic routes to produce high-quality graphene-based materials.
