From Quanta Magazine (find original story here). Spaghetti-thin shoelaces, sturdy hawsers, silk cravats—all are routinely tied in knots. So too, physicists believe, are water, air and the liquid iron ...

IN a communication published recently on “Flow of Water through Very Narrow Channels”, Reekie and Aird 1 give results obtained from measurements of the flow of both water and air through plugs of very ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

Textbook formulas for describing heat flow characteristics, crucial in many industries, are oversimplified, study shows. Whether it's water flowing across a condenser plate in an industrial plant, or ...

The trade-offs necessary to choose a fluid involve a consideration of application requirements such as health, safety, and environmental effects, and fluid properties such as viscosity, stability, ...

New work could help design electronic devices in which heat can be guided in certain directions, minimizing heat loss ...
