Herein, we report a cleavable BDW design that effectively expands the target sets of this class of signal amplifiers. Specifically, we first demonstrated that folded DNA structures at the 3` end of BDW are highly efficient steric blockers capable of fully deactivating BDW. Using a RNA cleaving DNAzyme serving both as a steric blocker and a target cleavable motif, we successfully engineered a signal amplifier for uranyl ions with a limit of detection at 1.0 nM. Our study enriches the design rules for engineering DNA nanomachines as highly efficient biosensors.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"18 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Gigawatt-hour to terawatt-hour salt cavern supercapacitor and supercapattery","authors":"Tingting Jiang, Jingjie Li, George Zheng Chen","doi":"10.1039/d4cc06169a","DOIUrl":"https://doi.org/10.1039/d4cc06169a","url":null,"abstract":"The advancement of energy technology has led to a notable increase in the contribution from renewable energy sources to the global energy supply and consumption landscape. Nevertheless, although inexhaustible and clean, the intermittency and instability of these energy sources present significant challenges to their wider deployment, necessitating the development of robust energy storage systems. Also, it is historical that the demand for power supply also varies significantly between day and night, and between different time zones, requesting large scale storage capacity for not only load levelling but also power supply security. In this article, salt caverns, which offer a sealable and unmatched large space and are currently employed for storage of compressed energy gases, are proposed for construction of giga- to tera-watt-hour scale supercapacitors and supercapatteries as an effective storage solution to renewable energy farms and national and international power grids. Following an introduction to salt caverns and their uses for storage of nature gas, hydrogen and carbon dioxide, the potential is explored for construction of supercapacitors and supercapatteries in salt caverns. The discussion is specially focused on aqueous electrolytes that can be formed by utilising the salty water or brine from the construction of the salt cavern, and the respective electrode materials suitable for such aqueous electrolytes. Further, calculations and analyses are given on the prospects of construction and application of giga- to tera-watt-hour supercapacitor and supercapattery in salt caverns. Last, but not the least, foreseeable challenges on such unprecedented ultra-large scale electrochemical energy storage are discussed with possible solutions.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"36 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monoester substituted -hydroxy cyclopropenes on treatment with catalytic Bi(OTf)3 lead to [5,5]/[6,5] oxaspirocyclic lactones. This unified strategy relies on generation of transient donor-acceptor (D-A) cyclopropanes from -hydroxy cyclopropene precursors.
