Comparative study of the toxicity responses of Vallisneria natans and Pistia stratiotes to sulfadiazine under different planting methods.

Sulfonamides are receiving increased attention due to their persistence in the environment and potential ecological risks. However, there are currently relatively few studies on the toxicity response of aquatic plants grown under the single and mixed planting methods to sulfadiazine (SD). This study investigated the response of the Vallisneria natans (Lour.

Two-Dimensional Tantalum Carbide (MXenes) Composite Nanosheets for Multiple Imaging-Guided Photothermal Tumor Ablation.

MXenes, an emerging family of graphene-analogues two-dimensional (2D) materials, have attracted continuous and tremendous attention in many application fields because of their intrinsic physiochemical properties and high performance in versatile applications. In this work, we report on the construction of tantalum carbide (TaC) MXene-based composite nanosheets for multiple imaging-guided photothermal tumor ablation, which has been achieved by rational choice of the composition of MXenes and their surface functionalization. A redox reaction was activated on the surface of tantalum carbide (TaC) MXene for in situ growth of manganese oxide nanoparticles (MnO/TaC) based on the reducing surface of the nanosheets.
