In industrial activities such as thermal power generation, the incomplete combustion of fossil fuels such as coal releases sulfur dioxide (SO2), causing harm to ecosystems. Due to the uneven development between regions in China, heavy industries such as thermal power generation will exist for a long time, which will lead to a long-term process of sulfur dioxide control. Therefore, there is an urgent need to develop a simple, accurate, and reliable SO2 concentration detection equipment in order to conduct grid monitoring and implement SO2 source control throughout the country. In addition, given the vast territory of China and the significant difference between the north and south environments, the equipment also needs to have good adaptability. In this paper, variational mode decomposition (VMD) and BP neural network are used to optimize the detection data, which effectively reduces the influence of electronic noise and temperature drift by about 66% and 12%, respectively, and significantly improves the accuracy and reliability of the detection equipment.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144045328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial studies were enabled by manual \"Scotch Tape\" exfoliation; nearly two decades later, this method is still widely used to obtain chemically pristine flakes of graphene and other 2D van der Waals materials. Unfortunately, the yield of large, pristine flakes with uniform thickness is inconsistent. Thus, significant time and effort are required to exfoliate and locate flakes suitable for fabricating multilayer van der Waals heterostructures. Here, we describe a relatively affordable tabletop device (the \"eXfoliator\") that can reproducibly control key parameters and largely automate the exfoliation process. In a typical exfoliation run, the eXfoliator produces 3 or more large (≥400μm2) high-quality graphene monolayer flakes, allowing new users to produce such flakes at a rate comparable to manual exfoliation by an experienced user. We use an automated mapping system and a computer vision algorithm to locate candidate flakes. Our results provide a starting point for future research efforts to identify more precisely which parameters matter for the success of exfoliation and to optimize them.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144079895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The shear cell can be mounted on an inverted confocal microscope that is used to image the deformation of a calibrated polymer gel with embedded tracers, from which the shear stress is determined. The gels have shear moduli G ∼ 1-10 Pa, which, when combined with the high strain resolution afforded by single-particle locating of the embedded tracers, are sufficiently compliant to measure mPa stresses. While these exceptionally compliant gels are necessary to achieve mPa stress resolution, they are easily deformed by surface tension, leading to several technical challenges with their fabrication and functionalization. To overcome these challenges, a fabrication technique using sacrificial molds is described, alongside processing steps to functionalize the gels without distorting the surface. While the apparatus presented is designed specifically for simple shear deformation of soft solids, the processing and fabrication techniques can be employed to mold and fabricate compliant gels in other geometries.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144019170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
