Summary: In this study, high-surface-area amino-functionalized mesoporous silica nanoparticles (MSN-NH2) were synthesized and functionalized with benzoyl chloride (MSN-BC) for the release of benzoic acid (BA) in response to acidic and alkaline conditions. These MSN-BC nanoparticles were embedded in acrylic coatings for corrosion protection of aluminum alloys. The coatings showed long-lasting efficiency and were validated through morphological and electrochemical impedance spectroscopy (EIS) measurements, demonstrating their potential for aluminum alloy protection.

Summary: In this study, a drug delivery system based on mesoporous silica nanoparticles modified with heparin was fabricated to achieve sustainable and pH-responsive release of Platinum-based drugs. The modified nanoparticles showed high uniform spherical shape with a diameter of 89.03 +/- 4.49 nm, and had a loading capacity of cisplatin twice as the bare nanoparticles. The amount of drug released in tumor microenvironment (pH 5.8) was significantly higher than that released in physiological environment (pH 7.4). Cell toxicity assay confirmed the biocompatibility of the modified nanoparticles on MCF-7 cells. These results suggest that the heparin-modified nanoparticles have great potential as nanocarriers for chemotherapy with effectively loading ability and sustained release of Platinum-based drugs with pH response.

Summary: Using advanced functional materials and technologies to construct new, efficient, and controlled-release pesticide formulations can effectively improve the target utilization of pesticides and reduce their impact on nontarget organisms and the surrounding environment. The study presents a strategy for preparing pH-responsive nanodrug delivery systems that can release pesticides rapidly in acidic environments. The results show that the nanodrug delivery system has longer-lasting fungicidal activity and lower impact on non-target organisms and the environment. Moreover, it can provide trace elements required by plants to promote crop growth without disturbing normal growth.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
