“…At slightly higher concentrations, the sensing system had a wide detection range (0.01-185 µM) with a detection limit of 3.8 nM. And at even lower concentrations, Lei et al constructed copper and carbon composites with different morphologies than Xia et al to detect RAC [144]. As illustrated in Figure 8, the Cu nanoclusters anchored on biogenic carbon constituted a 3D fiber network topology structure, so a more negative potential and higher activity were obtained.…”

Considering the increasing concern for food safety, electrochemical methods for detecting specific ingredients in the food are currently the most efficient method due to their low cost, fast response signal, high sensitivity, and ease of use. The detection efficiency of electrochemical sensors is determined by the electrode materials’ electrochemical characteristics. Among them, three-dimensional (3D) electrodes have unique advantages in electronic transfer, adsorption capacity and exposure of active sites for energy storage, novel materials, and electrochemical sensing. Therefore, this review begins by outlining the benefits and drawbacks of 3D electrodes compared to other materials before going into more detail about how 3D materials are synthesized. Next, different types of 3D electrodes are outlined together with common modification techniques for enhancing electrochemical performance. After this, a demonstration of 3D electrochemical sensors for food safety applications, such as detecting components, additives, emerging pollutants, and bacteria in food, was given. Finally, improvement measures and development directions of electrodes with 3D electrochemical sensors are discussed. We think that this review will help with the creation of new 3D electrodes and offer fresh perspectives on how to achieve extremely sensitive electrochemical detection in the area of food safety.

“…In recent years, because of its outstanding material characteristics, silicon carbide materials are widely used in the fields of optics, semiconductors and so on, especially in the field of optics, silicon carbide ceramics can be used as a mold material, and is used [1]. In aspherical optical glass processing, optical mold tend to use work in extreme conditions, such as high temperature and high pressure environment, therefore, the optical abrasive materials must be can withstand high temperatures, and high wear resistance, because silicon carbide (SiC) ceramic material of outstanding features, and is considered to be an ideal material to make optical mold [2].…”

Difficult-to-machining materials are widely used in industry, due to their excellent material properties. However, the ultra-precision machining of difficult-to-machining is difficulty issue, due to their properties of super hard and super brittle. Ultrasonic assisted machining has a prominent role in processing difficult materials, because it combines the advantages of traditional processing and ultrasonic vibration. In this paper, ultrasonic assisted grinding processing method was used to machining silicon carbide material, using a self-made machining equipment, to explore the processing characteristics of ultrasonic assisted grinding in the processing of difficult-to-machining materials.
