A g-C3N4/nanocarbon/ZnIn2S4 (CN/C/ZIS) nanocomposite with enhanced photocatalytic H2 production performance has been successfully synthesized. Based on the experimental results, for the first time, it has been demonstrated that nanocarbon could be integrated into a Z-scheme photocatalytic system and acted as an excellent solid electron mediator.

We report on the fabrication of silica/zinc oxide/zinc sulfide nanoparticles (SiO 2 /ZnO/ZnS NPs) wrapped with thermoresponsive molecularly imprinted polymers (TMIPs) for photocatalysis (PC) applications. TMIPs were prepared via surface-initiated reversible addition− fragmentation chain transfer (SI-RAFT) polymerization of N-isopropylacrylamide (NIPAm) and ethylene glycol dimethacrylate (EGDMA), rendering the material solution accessible and temperature sensitive. Photodegradation of sulfadiazine (SD) was used as a probe to evaluate the effect of coated TMIPs on the PC performance of SiO 2 /ZnO/ZnS NPs. The results showed that TMIPs made SiO 2 /ZnO/ZnS NPs have an outstanding specific affinity PC activity toward template SD. Modification of SiO 2 /ZnO/ZnS NPs with Ag 2 S resulted in a tunable PC ability of the prepared material. For SI-RAFT conducted in a controlled manner, a thin layer of polymers (∼100 nm) formed around NPs was measured by a transmission electron microscopy (TEM). Also the polymers were characterized by Fourier transform infrared spectrometer and thermogravimetric analysis. Due to the specific binding of imprinted polymers, thermoresponsiveness of poly-NIPAm shells, and tunable PC ability of NPs cores, the obtained material catalyzed the original template SD with an appreciable selectivity over other structurally related antibiotics and the PC ability could be tunable by changing thte environmental temperature or NPs cores.

CdIn2S4/g-C3N4 heterojunction with excellent photocatalytic activities have been synthesized. The enhanced photocatalytic performance might be ascribed to the efficient photoinduced charge transfer derived from the heterojunction structure.

Circular RNA (circRNAs) is a covalently closed circular non-coding RNA formed by reverse back-splicing from precursor messenger RNA. It is found widely in eukaryotic cells and can be released to the surrounding environment and captured by other cell types. This, circRNAs serve as connections between different cell types for the mediation of multiple signaling pathways. CircRNAs reshape the tumor microenvironment (TME), a key factor involved in all stages of cancer development, by regulating epithelial-stromal transformation, tumor vascularization, immune cell function, and inflammatory responses. Immune cells are the most abundant cellular TME components, and they have profound toxicity to cancer cells. This review summarizes circRNA regulation of immune cells, including T cells, natural killer cells, and macrophages; highlights the impact of circRNAs on tumor progression, treatment, and prognosis; and indicates new targets for tumor immunotherapy.
