Wired Article Link- The Beauty of the Laplace Equation- Mathematical Key to .... Everything


Kibron devices like the AquaPi and DeltaPi can measure the air-water interface of surface tension in films that are governed by  governed by Laplace's law of capillary action.  Read more about this brilliant equation in Wired.  Washing dishes will never be the same...

New surface makes oil contamination remove itself

New surface makes oil contamination remove itself: Researchers have developed surfaces where oil transports itself to desired directions. Researchers' oleophobic surfaces are microtextured with radial arrays of undercut stripes. When oil drops fall on surfaces, drops move away from the landing point to the direction set by asymmetric geometrical patterning of the surface. The surfaces open up new avenues for power-free liquid transportation and oil contamination self-removal applications in analytical and fluidic devices.

I wonder if  Kibron devices may be able aid in this research...

Water Molecules Break Bonds Through Quantum Tunneling

http://www.sciencemag.org/news/2016/03/water-molecules-break-bonds-through-quantum-tunneling




Water molecules rotate like gears to break bonds.....


See the video below.









Water forms all the bonds of life.   If there is a way that there is some order then it is interesting to understand how that affects the molcules that they are bound to.

Blood drying







If someone gets shot the blood droplets will hit the ground.  With enough time the Water from the blood will evaporate changing the surface tension gradient across the the droplet.  These gradients can cause convection inside the drop and pushes the red blood cells towards the outer part of the drop leaving different patterns.  The patterns depend on what parts of the blood are deposited. 


Looking at the patterns it can show a difference between different types of red blood cells e.g. anemic vs. normal blood.

Help! I’m Trapped in a Drop of Water

Help! I’m Trapped in a Drop of Water: A fish is entombed in a water droplet in zero-g … or is it?




Pretty awesome!  Water surface tension and a drop elevator (creating a zero gravity environment) keeps the fish in place.

How to skip stones? Scientists Perfect the Skipping Stone - D-brief

The best way to skip stones?  It has something to do with surface tension. Find out here: Scientists Perfect the Skipping Stone - D-brief: Scientists have created a better version of the skipping stone that's not a stone at all, but an elastic rubber ball.

Smart nanogels at the air/water interface: structural studies by neutron reflectivity


In order to do Neutron Reflectivity Measurments you need to have precise measurements at the surface tension.  Smart nanogels that contain a switchable characteristic that can be used in drug delivery are studied with this technique.
