“…Nanomaterials are tiny particles with size distribution less than 100 nm. In the last decades, various types of nanomaterials have attracted the attention of many researchers in photocatalysis (Pan et al, 2021), electrocatalysis (Zhang et al, 2021a), photoelectrocatalysis (Hu et al, 2020;Zhao et al, 2020;Huang et al, 2021), solar utilization (Jiang et al, 2020), heat management (Zhang et al, 2021b) and other fields because of their unique properties (Wang et al, 2019;He et al, 2020). Among the numerous materials, Au represents one well-studied type (Xu et al, 2016) with tunable shape (Zhu et al, 2015), structure (Ma et al, 2015), and composition (Jiang et al, 2017).…”

Recently, as our population increasingly ages with more pressure on bone and cartilage diseases, bone/cartilage tissue engineering (TE) have emerged as a potential alternative therapeutic technique accompanied by the rapid development of materials science and engineering. The key part to fulfill the goal of reconstructing impaired or damaged tissues lies in the rational design and synthesis of therapeutic agents in TE. Gold nanomaterials, especially gold nanoparticles (AuNPs), have shown the fascinating feasibility to treat a wide variety of diseases due to their excellent characteristics such as easy synthesis, controllable size, specific surface plasmon resonance and superior biocompatibility. Therefore, the comprehensive applications of gold nanomaterials in bone and cartilage TE have attracted enormous attention. This review will focus on the biomedical applications and molecular mechanism of gold nanomaterials in bone and cartilage TE. In addition, the types and cellular uptake process of gold nanomaterials are highlighted. Finally, the current challenges and future directions are indicated.

“…As an efficient and clean energy source, rechargeable secondary batteries can effectively alleviate the current energy and environmental problems. 1,2 Lithium-ion batteries (LIBs) have been developed and commercialized by Sony in 1991. Due to their advantages of high energy density, long service life, low selfdischarge rate, low maintenance cost, and good safety, LIBs are widely used in portable electronic products.…”

“…In addition, hydrogen production from electrochemical water splitting can effectively solve the current energy crisis and environmental problems. However, the oxygen evolution reaction (OER) is the major bottleneck due to its high reaction overpotential and sluggish reaction kinetics, thus severely reducing the overall efficiency of hydrogen generation ( Teng et al, 2020 ; Zhang et al, 2021 ). Although ruthenium- and iridium-based electrocatalysts have excellent OER efficiency, the high cost and low natural abundance of precious metals seriously impede their widespread applications ( Laha et al, 2019 ; She et al, 2022 ).…”

Large-scale synthesis of graphene-based nanomaterials in stirred tank reactor (STR) often results in serious agglomeration because of the poor control during micromixing process. In this work, reactive impingement mixing is conducted in a two-stage impinging jet microreactor (TS-IJMR) for the controllable and scale-up synthesis of nickel-cobalt boride@borate core-shell nanostructures on RGO flakes (NCBO/RGO). Benefiting from the good process control and improved micromixing efficiency of TS-IJMR, NCBO/RGO nanosheet provides a large BET surface area, abundant of suitable mesopores (2–5 nm), fast ion diffusion, and facile electron transfer within the whole electrode. Therefore, NCBO/RGO electrode exhibits a high specific capacitance of 2383 F g−1 at 1 A g−1, and still retains 1650 F g−1 when the current density is increased to 20 A g−1, much higher than those of nickel boride@borate/RGO (NBO/RGO) and cobalt boride@borate/RGO (CBO/RGO) synthesized in TS-IJMR, as well as NCBO/RGO-S synthesized in STR. In addition, an asymmetric supercapacitor (NCBO/RGO//AC) is constructed with NCBO/RGO and activated carbon (AC), which displays a high energy density of 53.3 W h kg−1 and long cyclic lifespan with 91.8% capacitance retention after 5000 charge-discharge cycles. Finally, NCBO/RGO is used as OER electrocatalyst to possess a low overpotential of 309 mV at a current density of 10 mA cm−2 and delivers a good long-term durability for 10 h. This study opens up the potential of controllable and scale-up synthesis of NCBO/RGO nanosheets for high-performance supercapacitor electrode materials and OER catalysts.
