Machine learning (ML) is expected to bring new insights into the impact of organic structures on the reaction mechanisms in reactive oxygen species oxidation. However, understanding the underlying chemical mechanisms still faces challenges due to the limited interpretability of the ML models. In this study, interpretable ML models were established to predict the second-order rate constants between hydroxyl radicals (OH) and organics ().

Solid-state fermentation (SSF) has emerged as an effective method for wheat bran valorization, providing advantages like cost reduction, decreased water usage, and enhanced product quality. In this study, wheat bran was fermented using to evaluate the extraction yield of soluble dietary fiber, the activities of protease and amylase, and the physicochemical characteristics of wheat bran during SSF. The findings demonstrated that the maximum yield of soluble dietary fiber was achieved after 120 h of fermentation at a moisture content of 55%.

Proteins and polyphenols exhibit distinct biological activities and functional properties. A comprehensive investigation into the formation mechanisms, structures, and functional properties of protein-polyphenol complexes will deepen our understanding of their interactions and establish a theoretical foundation and technical support for development of novel functional foods and pharmaceutical products. The almond protein-phloretin (AP-PHL) covalent complex was synthesized through the covalent binding of hydroxyl radicals to phloretin (PHL), utilizing almond protein (AP) as the raw material.

As a promising tumor treatment, chemodynamic therapy (CDT) can specifically catalyze HO into the cytotoxic hydroxyl radical (·OH) via Fenton/Fenton-like reaction. However, the limited HO and weakly acidic pH in tumor microenvironment (TME) would severely restrict the therapeutic efficiency of CDT. Here, a weakly acid activated, HO self-supplied, hyaluronic acid (HA)-functionalized Ce/Cu bimetallic nanoreactor (CBPNs@HA) is elaborately designed for complementary chemodynamic-immunotherapy.

Carbon quantum dots (CQDs) are emerging as a promising zero-dimensional carbon nanomaterial with the potential to enhance the catalytic properties of titanium dioxide nanoparticles (TiO NPs). Although CQDs modification alters the physicochemical properties of TiO NPs, the impact on their toxicity has been rarely explored. In this study, we investigated the effects of CQDs doping on the toxicity, bioaccumulation, and trophic transfer of TiO NPs using a representative aquatic food chain comprising phytoplankton (Scenedesmus obliquus), zooplankton (Daphnia magna), and fish (Danio rerio).
