Zinc dendrites are easily produced on anode surface during the cycling of zinc-based batteries. The introduction of TU-CQDs in alkaline electrolyte can uniform the zinc deposits and improve the reversibility of zinc plating/stripping processes.

In this paper, we reviewed the research progress for feeding silkworm with fluorescent additives to obtain naturally fluorescent silk in the past ten years, and summarized the unified characteristics and rules for the substances that can enter the silk gland by digestive tract of silkworms. The advantages and disadvantages of various fluorescent materials for this application are compared in detail, and the future research directions are suggested to overcome the shortcomings of the present research.

In this review, the preparation methods, properties and recent progress of deep-red to near-infrared CDs in recent years in biosensing and biomedicine are summarized, and the bottlenecks and potential of CDs for development in the above mentioned fields are discussed.

A novel supramolecular strategy based on strong hydrogen bonding has been developed to achieve matrix-free room-temperature phosphorescence for carbon dots (CDs), by covalent decoration of ureido-pyrimidinone on the surface of CDs via post-modification.

Here, we proposed one type of CDs doped with nitrogen and sulfur through the hydrothermal method, which exhibited the obvious yellow-fluorescence in aqueous solution. Importantly, the fluorescence intensity of CDs decreased with pH decreasing in the acidic range, thus exhibiting the potential of pH sensing. Importantly, introducing tigecycline into these CDs resulted in their decreased fluorescence, thus we further established a strategy of detecting tigecycline.
