Construction of the tunable oxygen vacancies (OVs) is widely utilized to accelerate molecular oxygen activation for boosting photocatalytic performance. Herein, the in-situ introduction of OVs on BiMoO was accomplished using a calcination treatment in an H/Ar atmosphere. The introduced OVs can not only facilitate carrier separation, but also strengthen the exciton effect, which accelerates singlet oxygen generation through the energy transfer process.

Establishing an effective and sustainable strategy for zearalenone (ZEN) degradation is of great significance to agricultural development and food safety. Herein, more than 98 % of ZEN (2 ppm) was photocatalytic degraded within 90 min over the oxygen-deficient BiWO ultrathin layers (BWO-U), along with the sharp elimination of biotoxicity to GES-1 cells. Theoretical calculations and characterizations revealed the ultrathin structure and oxygen vacancies endowed BWO-U with strengthened photoelectrochemical activity and O-adsorption capacity, facilitating the generation of •O and O which play decisive roles in ZEN degradation.

Sensitive, on-site and multiple detection of mycotoxins is a vital early-warning tool to minimize food losses and protect human health and the environment. Although paper-based lateral flow immunoassay (LFIA) has been extensively applied in mycotoxins monitoring, low-cost, portable, ultrasensitive and quantitative detection is still a formidable challenge. Herein, a series of Fe-N-C single-atom nanozymes (SAzymes) were synthesized and systematic characterized.

Mycotoxins are toxic secondary metabolites generated from toxigenic fungi in the contaminated food and agro-food, which have been regarded as a serious threat to the food safety and human health. Therefore, the control of mycotoxins and toxigenic fungi contamination is of great significance and has attracted the increasing attention of researchers. As we know, nano-semiconductors have many unique properties such as large surface area, structural stability, good biocompatibility, excellent photoelectrical properties, and low cost, which have been developed and applied in many research fields.

As computational fluid dynamics (CFD) advances, entropy generation minimization based on CFD becomes attractive for optimizing complex heat-transfer systems. This optimization depends on the accuracy of CFD results, such that accurate turbulence models, such as elliptic relaxation or elliptic blending turbulence models, become important. The performance of a previously developed elliptic blending turbulence model (the SST k-ω-φ-α model) to predict the rate of entropy generation in the fully developed turbulent circular tube flow with constant heat flux was studied to provide some guidelines for using this class of turbulence model to calculate entropy generation in complex systems.
