Investigations of Thin Liquid Layers between Solid

By a special method the disjoining pressure of water caused by a molecular long range orienta­ tion between fully hydroxylated and highly polished fused silica surfaces at different temperatures (0 — 74 °C) and plate distances ^ 1000 A was determined. Four marked maxima were found at about 15°, 32°, 45°, and 61 °C for not too small plate distances. At these temperatures many authors have detect...

Viscous withdrawal of miscible liquid layers.

In viscous withdrawal, a converging flow imposed in an upper layer of viscous liquid entrains liquid from a lower, stably stratified layer. Using the idea that a thin tendril is entrained by a local straining flow, we propose a scaling law for the volume flux of liquid entrained from miscible liquid layers. A long-wavelength model including only local information about the withdrawal flow is de...

Lots of Headroom

a sense of how deeply computing practices have permeated experimental optics R&D. I found scant mention of computation in these reports; I can’t recall whether my first reaction to this revelation was surprise or disappointment. Instead, I tried to determine why only two of these scores of reports indicated that computation had played a sufficiently important role in their discoveries that they...

Bacterial Interactions with Immobilized Liquid Layers.

Bacterial interactions with surfaces are at the heart of many infection-related problems in healthcare. In this work, the interactions of clinically relevant bacteria with immobilized liquid (IL) layers on oil-infused polymers are investigated. Although oil-infused polymers reduce bacterial adhesion in all cases, complex interactions of the bacteria and liquid layer under orbital flow condition...
