Summary: In this study, we prepared a copper nanofibril assembly using thermal oxidation and electrochemical reduction processes. The resulting structure exhibited excellent glucose detection ability with a high sensitivity, low detection limit, wider linear range, and long-term stability. The enhanced glucose sensing ability of the copper nanofibril structure can be attributed to its morphology, origin of the Cu (111) facet, and formation of a stable oxide layer. This structure showed no response to other interfering substances such as chloride ion, dopamine, ascorbic acid, and uric acid, making it a promising candidate for glucose sensing applications.

Summary: Two Cu(II) (C1) and Ni(II) (C2) complexes were synthesized and characterized, showing distorted octahedral geometry. MTT assays revealed that the complexes have significant antiproliferative effects on BEL-7404 cells, with C1 being more potent than C2. Cellular uptake of the complexes suggests that different levels of ROS production may contribute to their differential cytotoxicity. Mechanistically, C1 induces apoptosis through a caspase-dependent mitochondrion pathway, while C2 induces BEL-7404 cell death through the RAGE/PI3KC3/Beclin 1 autophagic cell signaling pathway.

Summary: A novel catalyst for simultaneous adsorption and heterogeneous Fenton processes was synthesized using an in-situ granulation method. The catalyst, Fe3O4/CuBDC/Cellulose nanocomposites, showed high efficiency in removing the trisazo dye, direct blue 71 (DB71).

Summary: Researchers have developed a photocoupled electrocatalyst with high activity for CO2 reduction. The catalyst consists of aluminum-oxygen chains as the metal center and transition metal sites, and has achieved satisfactory CO2-to-CO conversion with a Faradaic efficiency as high as 90% and long-term stability over 35 hours under visible light. The improved performance is attributed to the stability provided by the aluminum-oxygen chains, the efficient charge transfer rate facilitated by the transition metal sites, and the accelerated charge transfer by visible light.

Summary: This study conducted the first ultrasonic synthesis of [Cu(L)4(SCN)2] (L = 1-methylimidazole) nanocomplex under ultrasonic irradiation, and comprehensively investigated its photocatalytic performance for the degradation of remdesivir (RS) under sunlight irradiation. The physicochemical properties of the synthesized photocatalyst were examined using various techniques. The nanocomplex showed efficient removal of remdesivir from water within 20 minutes, and the photodegradation process followed a pseudo-second-order kinetic model. The study confirmed that the [Cu(L)4(SCN)2] nanocomplex can effectively be used for the photodegradation of pharmaceutical contaminants.

Summary: p_Aminophenol, also known as 4-aminophenol (4-AP), is a chemical compound with hydroxyl and amino groups on the benzene ring. It is a suitable precursor for synthesizing oxazoles and oxazines. However, the toxicity of aniline and phenol poses a risk to human and environmental health, so it is important to develop reliable techniques for detecting and eliminating trace amounts of amino phenols.

Summary: Three nickel substituted Keggin-type polyoxometalates (SiW9Ni3) were selectively intercalated into Zn3Al based Layered Double Hydroxide (Zn3Al-LDH) using ion-exchange technique. The resulting nanocomposite, SiW9Ni3@Zn3Al, acted as a heterogeneous nanoreactor for the synthesis of drug-like aminoimidazopyridine small molecules via Ugi-type Groebke-Blackburn-Bienayme reaction (GBB 3-CRs) without any acid/additive under mild and solvent-free conditions. The catalytic property of SiW9Ni3@Zn3Al was enhanced compared to the individual components, indicating a synergistic catalytic effect between SiW9Ni3 polyoxometalate and Zn3Al-LDH precursors. The Lewis/Bronsted acidity of SiW9Ni3 polyoxometalate and Zn3Al-LDH precursors played essential roles in the catalytic performance of the composite.
