“…Once the amplitude of the alternating sound pressure exceeds a certain threshold, the nuclei of cavitation form, expand, and eventually break inside the liquid or at the liquid–solid interface. The breaking of cavitation bubbles provides high energy to exfoliate the layered structure of the borophene …”

“…The breaking of cavitation bubbles provides high energy to exfoliate the layered structure of the borophene. 51 The solvent medium also plays a significant role in this exfoliation process. The molecules of EtOH and H 2 O interact with the bulk boron powder and become trapped between the layers, weakening the van der Waals forces between them.…”

Borophene has undergone extensive exploration in recent years for potential applications in sensing, electronics, optoelectronics, and energy storage due to its promising properties. However, the existing synthesis methods, such as molecular beam epitaxy, chemical vapor deposition, and physical vapor deposition, are expensive and challenging to implement. Therefore, it is important to establish simple and scalable synthesis approaches for borophene nanosheets to realize their diverse applications. In this study, we utilized a mixed-solvent-based liquid phase exfoliation strategy using a solvent mixture containing 50% ethanol and 50% water for borophene nanosheet synthesis. Furthermore, we performed surface modifications of these nanosheets using arginine (Arg) molecules, leading to the formation of Arg-functionalized borophene quantum dots (B-Arg). These B-Arg quantum dots were used as a fluorescent probe for detecting folic acid (FA) in various media, including aqueous solutions, human blood serum (HBS), artificial urine (AU), and FA tablet solutions. The observed detection limits were approximately 14.91 nM, 14.22 nM, 14.32 nM, and 14.94 nM for aqueous media, HBS, AU, and FA tablets, respectively, for the linear concentration range of 0−6.66 μM.

“…The surface electrical structure's precise regulation is still lacking. Thus, binary LDH materials should be produced and their surface electronic structures described to provide a database for preparing electrocatalysts with exact surface electronic structures [253] . Chemical interaction between the interface's surficial and interior structures determines LDH material design and manufacture.…”

“…Currently, there have been numerous reports on using physical fields to enhance the electrocatalytic performance of materials. [37][38][39][40][41][42][43][44] Among them, applying mechanical load to the ends of an electrode to induce surface stress, thereby causing lattice changes in the electrode material during electrochemical processes, has been extensively investigated. [45][46][47][48] The coupling effect between strain and electrocatalysis has been confirmed through theoretical models and experimental observations.…”

With the advancement of scientific research, the introduction of external physical methods not only adds extra freedom to the design of electro‐catalytical processes for green technologies but also effectively improves the reactivity of materials. Physical methods can adjust the intrinsic activity of materials and modulate the local environment at the solid‐liquid interface. In particular, this approach holds great promise in the field of electrocatalysis. Among them, the ultrasonic waves have shown reasonable control over the preparation of materials and the electrocatalytic process. However, the research on coupling ultrasonic waves and electrocatalysis is still early. The understanding of their mechanisms needs to be more comprehensive and deep enough. Firstly, this article extensively discusses the adhibition of the ultrasonic‐assisted preparation of metal‐based catalysts and their catalytic performance as electrocatalysts. The obtained metal‐based catalysts exhibit improved electrocatalytic performances due to their high surface area and more exposed active sites. Additionally, this article also points out some urgent unresolved issues in the synthesis of materials using ultrasonic waves and the regulation of electrocatalytic performance. Lastly, the challenges and opportunities in this field are discussed, providing new insights for improving the catalytic performance of transition metal‐based electrocatalysts.
