“…Moreover, the HRTEM images reflect the lattice fringes and an interface between the ZnS, Co 3 S 4 , and NiO. The d spacing of 0.31 and 0.23 nm can be ascribed to the (1 1 1) and (4 0 0) crystalline planes of ZnS [42] and Co 3 S 4 , [43] respectively (Figure 5b). The d spacing of 0.21 and 0.24 nm corresponds to the (2 0 0) and (1 1 1) crystalline planes of NiO, respectively [44] (Figure 5e).…”

Designing electrode materials with high reversible capacitance is the key to developing high‐performance pseudocapacitors. In this work, a novel ternary hybrid material, porous ZnS@Co3S4@NiO nanosheets are successfully constructed through a morphology reshaping enabled by a hydrothermal method followed by calcination. From a macroscopic view, the introduction of NiO changes the nanorod morphology of ZnS@Co3S4, and forms a porous nanosheet structure. The porous architecture with an increased specific surface area can promote the transport of ions and electrons, accelerate the diffusion of the electrolyte, and offer more active sites for electrochemical reactions. These advantages enhance the electrochemical properties of ZnS@Co3S4@NiO nanosheets when used as electrode materials for supercapacitors. ZnS@Co3S4@NiO nanosheets deliver an initial capacitance of 1418.7 F g−1, and it also reaches 1550.9 F g−1 with a capacitance retention rate of 109.3% at 5 A g−1, after 5000 cycles. However, ZnS@Co3S4 nanorods only deliver an initial capacitance of 708.7 F g−1, and maintain 716.4 F g−1 with a capacitance retention rate of 101.1% after 5000 cycles. These results show that the ZnS@Co3S4@NiO nanosheets are a promising electrode material for high‐performance pseudocapacitor electrode, and morphology reshaping is an effective strategy to design high‐performance pseudocapacitive materials.

Quantum dots (QDs) are semiconductor materials that have gained great interest due to their unique characteristics like optical properties. They are extensively being used in different areas, including solar cells, light-emitting diodes, laser technology, as well as biological and biomedical applications. In this review, comprehensive information about different aspects of QDs is provided, including their types and classifications, synthesis approaches, in vitro and in vivo toxicity, biological applications, and potentials in clinical applications. With a focus on the biological aspects, the respective in vitro and in vivo studies are collected and presented. Various surface modifications on QDs are discussed as directly influencing their properties like toxicity and optical abilities. Given the promising results, these materials are clinically used for targeted molecular therapy and imaging. However, there are a large number of questions that should be addressed before the wide application of QDs in a clinical setting. Regarding the existing barriers to QDs, suggestions are given and discussed to present an appropriate route for the clinical use of these materials.
