Article Abstract
Four stable 19-electron Fe and Co sandwich electron-reservoirs and three hydride reservoir complexes reduce the prototypal nanocluster Au25(SR)18 (R = CH2CH2Ph) leading to a largely increased kinetic stabilization of the anionic nanocluster form compared to previously known nanocluster anion salts; these salts represent new and robust nanocomposite anionic gold clusters with 18-electron sandwich complexes as counter cations.

A CoO/AgMoO/CeOternary nanocomposites photocatalyst was successfully synthesized through a straightforward ethanol-assisted chemical method. Comprehensive characterization of its structural and optical properties was conducted using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS), and photoluminescence (PL) analysis. XRD analysis confirmed the presence of CoO, AgMoO and CeO in the ternary composite sample.

Flavonoids are a major class of natural polyphenolic compounds with potent antioxidant, anti-inflammatory and anticancer properties. Among them, quercetin and catechin have been widely studied due to their significant health benefits and potent free radical scavenging activity. The efficient extraction and separation of these structurally similar antioxidants remains challenging, necessitating the development of high-performance adsorbents.

A sensitive electrochemical glucose biosensor using ZrO₂@CNTs nanocomposite was developed for real-time metabolism monitoring for athletes. The nanocomposite was prepared by a simple ultrasound-assisted technique, and the glucose oxidase (GOx) was covalently immobilized to improve the biorecognition ability. CNTs treated with acid served as a highly conductive framework, and ZrO₂ nanoparticles can provide structural stability and catalytic performance, thus showing synergistic enhancement of electron transfer kinetics and enzyme loading capacity.

Sepiolite (SP) is a naturally occurring sedimentary silicate clay mineral known for its unique structure, high surface area, and rich surface chemistry, particularly silanol groups (Si-OH), which facilitate strong interfacial interactions in polymer matrices. Its ability to act as a nanofiller has gained attention in the development of advanced biopolymer nanocomposites, especially for food packaging applications where material performance, sustainability, and safety are critical. SP enhances the thermal stability, barrier properties, and mechanical strength of starch and other biopolymer matrices, key factors in extending shelf life.
