Resonance in swirling wakes and sloshing waves

Similarly to mechanical structures, stable flows can exhibit resonance when perturbed by an impulsive or harmonic forcing. Swirling wakes and sloshing waves belong to this kind of flows and manifest large energy response when excited close to their natural ...

Thermally-nucleated self-assembly of water and alcohol into stable structures at hydrophobic interfaces

Francesco Stellacci, Michele Ceriotti, Kislon Voitchovsky, Daniele Giofré

At the interface with solids, the mobility of liquid molecules tends to be reduced compared with bulk, often resulting in increased local order due to interactions with the surface of the solid. At room temperature, liquids such as water and methanol can f ...

Quasi-Instantaneous Bacterial Inactivation on Cu-Ag Nanoparticulate 3D Catheters in the Dark and Under Light: Mechanism and Dynamics

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

The first evidence for Cu-Ag (50%/50%) nanoparticulate hybrid coatings is presented leading to a complete and almost instantaneous bacterial inactivation in the dark (

Correlating Synthetic Methods, Morphology, Atomic-Level Structure, and Catalytic Activity of Sn-beta Catalysts

David Lyndon Emsley, Aaron James Rossini

Sn-beta zeolites prepared using different recipes feature very different catalytic activities for aqueous phase glucose isomerization, suggesting the presence of different active sites. A systematic study of the morphology and atomic-level structure of the ...

Laser-assisted inkjet printing of highly viscous fluids with sub-nozzle resolution

Demetri Psaltis, Christophe Moser, Paul Delrot, Miguel Antonio Modestino

Drop-on-demand inkjet printing is mostly based on thermal and piezo-actuation, allowing for densely packed nozzles in inkjet printers. However, the droplet diameter is typically defined by the nozzle diameter, thus limiting the range of viscosity that can ...

Unraveling the Salvinia Paradox: Design Principles for Submerged Superhydrophobicity

Simone Meloni

The complex structure of the Salvinia molesta is investigated via rare event molecular dynamics simulations. Results show that a hydrophilic/hydrophobic patterning together with a re-entrant geometry control the free energy barriers for bubble nucleation a ...

Mechanism of the Cassie-Wenzel transition via the atomistic and continuum string methods

Simone Meloni

The string method is a general and flexible strategy to compute the most probable transition path for an activated process (rare event). We apply here the atomistic string method in the density field to the Cassie-Wenzel transition, a central problem in th ...

Modeling capillary forces for large displacements

Massimo Mastrangeli, Pierre Lambert

Originally applied to the accurate, passive positioning of submillimetric devices, recent works proved capillary self-alignment as effective also for larger components and relatively large initial offsets. In this paper, we describe an analytic quasi-stati ...

Investigation of liquid pinning on surface nanoscale topography

Capillarity assisted particle assembly (CAPA), is a powerful technique which is gaining in importance. Indeed the application possibilities are vast but, due to its relatively early research stage, the optimal and generic assembly parameters have yet to be ...

Impact of MOF topology upon solvent organization, dynamics, and solution phase stability

Wendy Lee Queen, Xiaoning Yang

One large gap in research related to hybrid org./inorg. frameworks pertains to the inability to rationally design materials with targeted structural features and hence properties, a problem that stems from a lack of knowledge of their crystn. processes. Li ...
