Furthermore, there has been great progress in the potential applications of advanced nanomaterials in biosensors. Every year there are several advances in sensing techniques that can be attributed to nanomaterials, biorecognition elements, or their related fabrication techniques. The further development of nanotechnology-based sensors provides a wide variety of opportunities to modern research. Advanced nanomaterials can provide remarkable optical, electrical, mechanical, and catalytic properties. For example, transition metals and organic polymers have been used in the fabrication of powerful, sensitive, and precise biosensors. The distinctive properties of advanced nanomaterials have been widely incorporated into biosensors. However, fabrication techniques also play important roles in the development of these devices. Therefore, we present a review of some of the advanced nanomaterials that have been widely used over the last few years and discuss their fabrication techniques.

Therefore, this paper proposes a new theoretical calculation model for accurately predicting the cutting force in ultra-precision machining, taking account of such factors. The model is first used to analyze the material deformation of the workpiece and the cutting force distribution along the cutting edge of a diamond tool. The size of the strain zone in different cutting deformation zones is then determined by using the distribution of strain work per unit volume and considering the characteristics of the stress distribution in these different deformation zones. Finally, the cutting force during ultra-precision machining is predicted precisely by calculating the material strain energy in different zones. A finite element analysis and experimental data on ultra-precision cutting of copper and aluminum are used to verify the predictions of the theoretical model. The results show that the error in the cutting force between the calculation results and predictions of the model is less than 14%. The effects of the rake face stress distribution of the diamond tool, the close contact zone, and material elastic recovery can be fully taken into account by the theoretical model. Thus, the proposed theoretical calculation method can effectively predict the cutting force in ultra-precision machining.","PeriodicalId":35428,"journal":{"name":"Nami Jishu yu Jingmi Gongcheng/Nanotechnology and Precision Engineering","volume":"4 1","pages":"043001"},"PeriodicalIF":3.7,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/10.0005648","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46006936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various delivery methods, recent years have seen the emergence of electroporation-based techniques that provide versatile platforms for molecule delivery, with high efficiency and controlled dosage. In this Review, we describe recent electroporation-based systems for intracellular molecule delivery. The principles of electroporation for cell membrane perforation and cargo delivery are briefly summarized. Focusing on various scenarios for the application of electroporation, we review electroporation devices that variously employ structures based on nanochannels, nanostraws, and flow-through microfluidic channels for in vitro intracellular molecule delivery. We also consider in vivo targeted therapies based on delivery of active molecules by electroporation according to the lesion locations. Finally, we discuss the current challenges facing electroporation-based techniques, as well as opportunities for their future development, which may lead to innovations in intracellular molecule delivery both for cellular analysis in the laboratory and treatment in the clinic.","PeriodicalId":35428,"journal":{"name":"Nami Jishu yu Jingmi Gongcheng/Nanotechnology and Precision Engineering","volume":"4 1","pages":"045001"},"PeriodicalIF":3.7,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/10.0005649","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45377058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental research investigated the radial wear of the dicing blade, the maximum spindle current, the surface morphology of the SiC die, the number of chips longer than 10 µm, and the chipped area, which depend on the dicing process parameters such as spindle speed, feed speed, and cutting depth. The chipping fractures in the SiC had obvious brittle fracture characteristics. The performance of the metal-bonded dicing blade was inferior to that of the resin-bonded dicing blade. The cutting depth has the greatest influence on the radial wear of the dicing blade, the maximum spindle current, and the damage to the SiC wafer. The next most important parameter is the feed speed. The parameter with the least influence is the spindle speed. The main factor affecting the dicing quality is blade vibration caused by spindle vibration. The optimal SiC dicing was for a resin-bonded dicing blade with a spindle speed of 20 000 rpm, a feed speed of 4 mm/s, and a cutting depth of 0.1 mm. To improve dicing quality and tool performance, spindle vibrations should be reduced. This approach may enable high-speed dicing of SiC wafers with less dicing damage.","PeriodicalId":35428,"journal":{"name":"Nami Jishu yu Jingmi Gongcheng/Nanotechnology and Precision Engineering","volume":"4 1","pages":"033004"},"PeriodicalIF":3.7,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1063/10.0005152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46977308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
