Open Forum Infect Dis. 2016 Jan 29;3(1):ofw011. doi: 10.1093/ofid/ofw011. eCollection 2016 Jan.

Background.  Antibiotic-associated diarrhea (AAD) and Clostridium difficile-associated diarrhea (CDAD) are common complications of antibiotic use. Data on the efficacy of probiotics to prevent AAD and CDAD are unclear. We aimed to evaluate the efficacy of Saccharomyces boulardii to prevent...

Dynamics of high-speed micro-drop impact: numerical simulations and experiments at frame-to-frame times below 100 ns.

Soft matter

Visser CW, Frommhold PE, Wildeman S, Mettin R, Lohse D, Sun C.
PMID: 25607820
Soft Matter. 2015 Mar 07;11(9):1708-22. doi: 10.1039/c4sm02474e.

Technologies including (3D-) (bio-)printing, diesel engines, laser-induced forward transfer, and spray cleaning require optimization and therefore understanding of micrometer-sized droplets impacting at velocities beyond 10 m s(-1). However, as yet, this regime has hardly been addressed. Here we present...

Forces encountered by a sphere during impact into sand.

Physical review. E, Statistical, nonlinear, and soft matter physics

Joubaud S, Homan T, Gasteuil Y, Lohse D, van der Meer D.
PMID: 25615033
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Dec;90(6):060201. doi: 10.1103/PhysRevE.90.060201. Epub 2014 Dec 15.

We describe direct measurements of the acceleration of an object impacting on a loosely packed granular bed under various pressures, using an instrumented sphere. The sphere acts as a noninvasive probe that measures and continuously transmits the acceleration as...

Electrolysis-Driven and Pressure-Controlled Diffusive Growth of Successive Bubbles on Microstructured Surfaces.

Langmuir : the ACS journal of surfaces and colloids

van der Linde P, Moreno Soto Á, Peñas-López P, Rodríguez-Rodríguez J, Lohse D, Gardeniers H, van der Meer D, Fernández Rivas D.
PMID: 29041778
Langmuir. 2017 Nov 14;33(45):12873-12886. doi: 10.1021/acs.langmuir.7b02978. Epub 2017 Oct 31.

Control over the bubble growth rates forming on the electrodes of water-splitting cells or chemical reactors is critical with respect to the attainment of higher energy efficiencies within these devices. This study focuses on the diffusion-driven growth dynamics of...

How a Surface Nanodroplet Sits on the Rim of a Microcap.

Langmuir : the ACS journal of surfaces and colloids

Peng S, Dević I, Tan H, Lohse D, Zhang X.
PMID: 27183892
Langmuir. 2016 Jun 14;32(23):5744-54. doi: 10.1021/acs.langmuir.6b01153. Epub 2016 Jun 03.

The location and morphology of femtoliter nanodroplets that nucleate and grow on a microcap-decorated substrate in contact with a liquid phase were investigated. We experimentally examined four different wetting combinations of the flat area and the microcaps. The results...

Toward 3D Printing of Pure Metals by Laser-Induced Forward Transfer.

Advanced materials (Deerfield Beach, Fla.)

Visser CW, Pohl R, Sun C, Römer GW, Huis in 't Veld B, Lohse D.
PMID: 26045211
Adv Mater. 2015 Jul 15;27(27):4087-92. doi: 10.1002/adma.201501058. Epub 2015 Jun 05.

3D printing of common metals is highly challenging because metals are generally solid at room conditions. Copper and gold pillars are manufactured with a resolution below 5 μm and a height up to 2 mm, using laser-induced forward transfer...

Manipulating target size influences perceptions of success when learning a dart-throwing skill but does not impact retention.

Frontiers in psychology

Ong NT, Lohse KR, Hodges NJ.
PMID: 26441753
Front Psychol. 2015 Sep 14;6:1378. doi: 10.3389/fpsyg.2015.01378. eCollection 2015.

Positive feedback or experiences of success during skill acquisition have been shown to benefit motor skill learning. In this study, our aim was to manipulate learners' success perceptions through a minor adjustment to goal criterion (target size) in a...

Dynamic Leidenfrost Effect: Relevant Time and Length Scales.

Physical review letters

Shirota M, van Limbeek MA, Sun C, Prosperetti A, Lohse D.
PMID: 26918994
Phys Rev Lett. 2016 Feb 12;116(6):064501. doi: 10.1103/PhysRevLett.116.064501. Epub 2016 Feb 10.

When a liquid droplet impacts a hot solid surface, enough vapor may be generated under it to prevent its contact with the solid. The minimum solid temperature for this so-called Leidenfrost effect to occur is termed the Leidenfrost temperature,...

Tanning Bed Perception Survey: A Questionnaire-based Study.

The Journal of clinical and aesthetic dermatology

Formation of surface nanodroplets under controlled flow conditions.

Proceedings of the National Academy of Sciences of the United States of America

Zhang X, Lu Z, Tan H, Bao L, He Y, Sun C, Lohse D.
PMID: 26159418
Proc Natl Acad Sci U S A. 2015 Jul 28;112(30):9253-7. doi: 10.1073/pnas.1506071112. Epub 2015 Jul 09.

Nanodroplets on a solid surface (i.e., surface nanodroplets) have practical implications for high-throughput chemical and biological analysis, lubrications, laboratory-on-chip devices, and near-field imaging techniques. Oil nanodroplets can be produced on a solid-liquid interface in a simple step of solvent...

Pinning and gas oversaturation imply stable single surface nanobubbles.

Physical review. E, Statistical, nonlinear, and soft matter physics

Lohse D, Zhang X.

Surface nanobubbles are experimentally known to survive for days at hydrophobic surfaces immersed in gas-oversaturated water. This is different from bulk nanobubbles, which are pressed out by the Laplace pressure against any gas oversaturation and dissolve in submilliseconds, as...
