Rebound suppression often involves high energy dissipation, while rebound enhancement requires minimal energy loss, rendering them traditionally considered mutually exclusive. Here, we present a unique bouncing behavior of pomegranate-like compound drops, signifying a remarkable transition from suppression to enhancement achieved solely by increasing the volume fraction (<i>Φ</i>) of dispersed droplets. The transition is induced by the jamming of dispersed droplets when <i>Φ</i> becomes sufficiently high. In the non-jamming state at low <i>Φ</i>, rebound suppression is governed by heightened viscous dissipation due to highly disordered internal flow. Conversely, in the jamming state at high <i>Φ</i>, the densely packed dispersed droplets constrain internal flow, and rebound enhancement emerges due to increased capacity for energy storage. The coexistence of rebound suppression and enhancement enriches our understanding of drop impact dynamics and unlocks possibilities for the precise and adaptable control of complex drops in various applications.","PeriodicalId":80456,"journal":{"name":"Andover Newton quarterly","volume":"2 2","pages":"100298-100298"},"PeriodicalIF":0.0,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While substantial progress has been made in understanding room-temperature droplet impact dynamics, the bouncing behavior of high-temperature droplets remains underexplored. Given the prevalence of hot and burning droplets in scenarios such as fireworks, fuel sprays, and fire safety, it is critical to understand droplet bouncing dynamics under these conditions. This study reveals a previously unexamined enhancement in the bouncing of high-temperature droplets, both burning and non-burning, on various solid surfaces, including smooth and rough substrates, with different contact angles. Through experimental investigations and numerical simulations, this work demonstrates the significant influence of the Marangoni effect, which arises from the uneven cooling of high-temperature droplets, leading to an increase in gas-film thickness that enhances the rebound. This enhanced bouncing behavior opens up possibilities for further applications, such as improving the combustion efficiency of fuel-spray droplets and inspiring the design of fire-retardant coatings that leverage the strategy of repelling burning droplets. © 2025 The Author(s)","PeriodicalId":80456,"journal":{"name":"Andover Newton quarterly","volume":"1 1","pages":"100014-100014"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.cell.com/action/showPdf?pii=S2950636025000064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
