BACKGROUND During high-intensity focused ultrasound (HIFU) surgical procedures, there is a need to rapidly ablate pathological tissue while minimizing damage to healthy tissue. Current techniques are limited by relatively long procedure times and risks of off-target heating of healthy tissue. One possible solution is the use of microbubbles, which can improve the efficiency of thermal energy de...

The dynamics of vibrational wave packets excited in Na2 dimers in the triplet ground and excited states is investigated by means of helium nanodroplet isolation (HENDI) combined with femtosecond pump-probe spectroscopy. Different pathways in the employed resonant multiphoton ionization scheme are identified. Within the precision of the method, the wave packet dynamics appears to be unperturbed ...

Nanotechnology, with its broad impact on societally relevant applications, relies heavily on the availability of accessible nanofabrication methods. Even though a host of such techniques exists, the flexible, inexpensive, on-demand and scalable fabrication of functional nanostructures remains largely elusive. Here we present a method involving nanoscale electrohydrodynamic ink-jet printing that...

On nanopillar-arrayed superhydrophobic surfaces, the contact time of oblique nanodroplet impacts is for first investigated via molecular dynamics simulations. Here, are triggered by nanodroplets impacting surfaces under various impact angles, α. The simulation results show that owing to non-axisymmetry spreading factors on always less rather than smooth same angles. As angle increased from 5° 6...

Molecular dynamics is used to investigate the thermocapillary motion of a water nanodroplet suspended in benzene subjected constant temperature gradient. This framework lets us identify average behavior fluid particles by revealing their mean evolution. We connect such statistics temporally evolving nanodroplet, thereby providing microphysical foundation existing macroscopic models that rely on...

This article provides a review of recent work in the field of helium nanodroplet spectroscopy with emphasis on the dynamical aspects of the interactions between molecules in helium as well as their interaction with this unique quantum solvent. Emphasis is placed on experimental methods and studies introducing recent new approaches, in particular including time-resolved techniques. Corresponding...

Microbubbles In article 2202281 by Jiang Li, Haosheng Chen, and co-workers, nanodroplet-coated microbubbles (NCMBs) are designed to realize a two-step cavitation strategy accelerate thrombolysis. The first drives nanodroplets into the thrombus, while second loosens thrombus. NCMBs can be used as promising medicines carrier with rapid diffusion help design of efficient drug delivery systems.
