Recently, there has been a growing interest in incorporating nanomaterials into CPEs to improve their performance and sensitivity. Here are some recent trends and applications of modified CPEs based on nanomaterials, which have been shown to have enhanced sensitivity and selectivity for the detection of various analytes such as those in food and drug samples. The high surface area and electrical conductivity of CPEs make them ideal for use in electrochemical sensing applications. Nanomaterial-based CPEs have also been widely studied for their high sensitivity and selectivity in sensing various analytes. Nanomaterials such as Multi-Walled Carbon Nanotube (MWCNT), Single-Walled carbon Nanotube (SWNCT), Graphene, or other naomaterial have excellent electrical conductivity, large surface area, and high mechanical strength, making it an attractive nanomaterial for use in CPEs. A CPEs-based nanomaterial has been used in electrochemical detection, demonstrating improved sensitivity compared to traditional CPEs. In general, the incorporation of nanomaterials into CPEs has opened up new opportunities for the development of highly sensitive and selective electrochemical sensors for a wide range of applications including environmental monitoring, drug diagnosis, and food safety.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are multiple Blockchain frameworks and networks for different use cases but still seems to be a gap in how different frameworks, protocols, and ledgers interact with each other. With the increase in the adoption of Blockchains, there is an increasing need for suitable interoperable solutions so that more value can be provided to the end user. This research focuses on analyzing how current Blockchain bridges are built and evaluating common security risks and countermeasures within the scope of interoperability. A threat model is proposed to analyze blockchain interoperability's various components, vulnerabilities, risks, and corresponding mitigation techniques. Common security vulnerabilities like centralization of trust and vulnerable smart contracts and others were identified and classified based on the kind of bridge component along with possible mitigations. Each solution, like Relays, HTLCs, Notary Schemes, and Smart Contracts, is explored. Thus, the study will help developers understand the risks involved by providing insights and pointing out the need for standardization on Blockchain interoperable solutions.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combustion is one of the major ways of energy conversion that produces very high amount of pollutant emission, as such the research arena has been taken over by coming up with combustion processes that are cleaner and efficient by the combustion engineers. Flameless combustion is one of the new techniques discovered by researchers to suppress NOx emission due to the low temperature inside the combustion zone that is well below the dissociation temperature of Nitrogen. Homogenous or proper mixing is another major factor that enhances combustion efficiency. An asymmetric swirling combustor is a unique shaped combustor that was developed by researchers in order to enhance better mixing inside the combustion zone without the need for an external swirler. The review investigated several parameters such as temperature uniformity, fuel flexibility and level of pollutant emission as discussed by researchers and it was found that the asymmetric swirling combustor is very efficient with temperature uniformity of about 0.9, thermal efficiency of 53% and very low NOx and CO of about 2ppm and 24ppm according to researchers. It was recommended that the combustor should be investigated under different flow configurations i.e. forward and reverse flow in order to know the optimum direction of flow for the asymmetric swirling combustor.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, MOSFETs are wired in parallel for applications that require high power. Theoretically, this circuit can multiply the current capability of parallel MOSFETs. However, even if all the MOSFETs in a parallel circuit have the same serial number and manufacturer, they might not necessarily have the same current characteristics. This could lead to issues with current imbalances, potentially causing harm to the MOSFETs, especially under severe circumstances. This study introduces a new Active Gate Driver (AGD) technique to balance the current in a parallel MOSFET circuit. The current difference can be used to modulate each MOSFET duty cycle. Specifically, the MOSFET with the smallest current capacity is configured as the Master, while the MOSFET following it is designated as the Slave. The interrupt time value for the duty cycle of each Slave MOSFET is influenced by the current differential between the Master and Slave. Consequently, different duty cycles for the Master and Slave MOSFETs can maintain the same current level. Based on the results of experiments conducted on three MOSFETs, it is evident that the AGD approach can effectively balance the current to an optimum level.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
