The technique of acoustic levitation normally produces a standing wave and the potential
well of the sound field can be used to trap small objects. Since no solid surface is involved it …

Conspectus Aerosols are ubiquitous in the atmosphere. Outdoors, they take part in the
climate system via cloud droplet formation, and they contribute to indoor and outdoor air …

Acoustic levitation has the potential to enable novel studies due to its ability to hold a wide
variety of substances against gravity under container-less conditions. It has found …

Acoustic vortices can transfer angular momentum and trap particles. Here, we show that
particles trapped in airborne acoustic vortices orbit at high speeds, leading to dynamic …

Beamline I22 at Diamond Light Source is dedicated to the study of soft-matter systems from
both biological and materials science. The beamline can operate in the range 3.7 keV to 22 …

Atmospheric aerosols influence the climate via cloud droplet nucleation and can facilitate
the long-range transport of harmful pollutants. The lifetime of such aerosols can therefore …

The potential of flow chemistry for nanomaterial synthesis has been amply demonstrated in
the last decade. Robust and reproducible synthetic protocols, scalability, high-throughput …

Organic aerosols are key components of the Earth's atmospheric system. The phase state of
organic aerosols is known to be a significant factor in determining aerosol reactivity, water …

Aerosols are significant to the Earth's climate, with nearly all atmospheric aerosols
containing organic compounds that often contain both hydrophilic and hydrophobic parts …

Focused acoustic vortex (FAV) beams can steadily trap particles in three-dimensions.
Previous FAV emitters are mainly based on the active device arrays. Here, we design a …
