Nevertheless, HECs, especially nanoscale HECs, remain far less developed than high-entropy alloys and conventional transition-metal carbides. Their vast compositional space is paired with tightly coupled challenges in phase formation, carbon stoichiometry, elemental mixing uniformity, surface chemistry and structure, all of which are difficult to regulate independently. This Review establishes a structure-synthesis-catalysis framework for the field. We examine the crystal chemistry, thermodynamic descriptors, and computational design strategies for navigating the extensive HEC composition space, and compare conventional thermal processing with emerging ultrafast synthetic routes. We further define the core structural evidence required to rigorously verify phase purity, intraparticle elemental distributions, carbon vacancies, and reaction-induced surface reconstruction. We then critically assess reported catalytic applications, distinguish well-substantiated findings from prospective opportunities, and identify key priorities for scalable synthesis, operando characterization, and predictive catalyst design. By bridging materials design principles with working-state structural verification, this Review provides a rigorous foundation for the rational development of HECs as functional catalytic materials.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"27 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173126","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}

Applying Poisson statistics to the fraction of positive partitions allows target concentration to be determined without an external calibration curve, offering a level of precision and reproducibility that conventional analog methods struggle to match. In this review, we organize the diverse digital bioassay frameworks around two complementary partitioning strategies: volume-based assays, which physically divide the sample into discrete reaction vessels such as droplets or microwells, and capture-based assays, which instead capture target molecules onto individual solid supports, including microbeads and patterned microspots. Within each strategy, we highlight how design choices, partition dispersity, capture specificity, isolation format, and signal localization can be combined modularly to tune precision, dynamic range, multiplexing capacity, and operational simplicity. We further show how these two partitioning logics increasingly converge in hybrid architectures, and how compartment-free signal amplification chemistries are relaxing the historical dependence of digital detection on dedicated microfluidic hardware. By providing a unified perspective on digital quantification, this review identifies common design principles across diverse assay formats and outlines opportunities for developing simpler, more accessible, and application-specific digital bioassays.</p>","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":" ","pages":"20243-20255"},"PeriodicalIF":4.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149035579","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}
