What to know about Explosive evaporation unlocks new possibilities in 3D printing and chemical analysis

Researchers studied the physics of charged water droplets on frictionless surfaces, observing that evaporation can cause spontaneous jets of microdroplets, a phenomenon called Coulomb fission. This discovery, which differs from previous studies on suspended droplets, suggests new methods for nanoscale fabrication and developing greener electrospray ionization techniques. The findings demonstrate how controlling surface tension and charge concentration can allow for precise control over microdroplet size and release.

What happened

Explosive evaporation unlocks new possibilities in 3D printing and chemical analysis Sadie Harley scientific editor Robert Egan associate editor Water droplets might seem simple at first.

Why it matters

But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects.

Common ground

In a Proceedings of the National Academy of Sciences publication, researchers have taken a closer look at the physics of charged water droplets on frictionless surfaces, observing spontaneous jets of microdroplet emissions.

fact_checkClaims Checked

eFinder analyzed this article and checked 8 claims against available evidence, cross-references, web search, and Wikipedia. Here is what the fact-checking layer found.

check_circle Corroborated 7
info Single Source 1
info
Claim 1: “Marcus Lin et al, Spontaneous Coulomb fissions of drops on lubricated surfaces, Proceedings of the National Academy of Sciences (2026). DOI: 10.1073/pnas.2538161123 On arXiv DOI: 10.48550/arxiv.2510.10368”
SINGLE SOURCE
The claim cites a specific paper and date (2026). While multiple web search results reference the title and topic, the date (2026) suggests a future or placeholder citation, and the provided evidence does not confirm its actual publication status or content beyond the title. Since the evidence is highly specific and repeated across search results, it is treated as a single, specific source reference without independent corroboration of the publication date/status.
