Second Liquid State???

Physicist reported in the International Journal of Nanotechnology noted that liquid water has a whole new set of properties when it hits temperatures between 40°C and 60°C. In this range, water can go into a  “crossover” phase or a second liquid state where the surface tension changes and other characteristics change....

Small droplets feel the vibe

Small droplets feel the vibe: A team of researchers have used ultrasonic forces to accurately pattern thousands of microscopic water-based droplets. Each droplet can be designed to perform a biochemical experiment, which could pave the way for highly efficient lab-on-a-chip devices with future applications in drug discovery and clinical diagnostics.



MEMBRANE FREE PROTOCELLS!!!  That is awesome!

Surface tension can sort droplets for biomedical applications

Surface tension can sort droplets for biomedical applications: A team led by Colorado State University's Arun Kota has engineered a simple and inexpensive device that can sort droplets of liquid based solely on the liquids' varying surface tensions.  They used Tunable Superomniphobic Surfaces for Sorting Droplets by Surface Tension that could make a wide range of biomedical applications using a Lab-on-a-Chip like device.  BAM!

The Maragoni Effect

Link to article: http://cen.acs.org/articles/94/web/2016/07/new-twist-common-lab-tool.html


In Analytical Chemistry Journal researchers led by Jose L. Garcia-Cordero et al from Center for Research and Advanced Studies at the National Polytechnic Institute in Monterrey, Mexico, reported that they designed an alternative that uses microsized pillars instead of wells as a bioassay technique.  An enzyme solution is added to a pillar and concentration by evaporation.  A sample solution (substrate) is added whereby the enzyme reacts to produce a product.  Surface tension keeps the droplet in place and the Maragoni effect where liquid flows to areas of higher surface tension helps the protein and the substrate mix. These Maragoni currents can be used for colorimetric assays as the evaporation is necessary for the reaction to occur.  Possibly it could be an advantage over plate-readers if the they could have faster reaction times or are dealing with substrates or proteins that might degrade or oxidize over a short time period.

The Ouzo Effect under the magnifying glass

The Ouzo Effect under the magnifying glass: Pour some water into your glass of ouzo or pastis, and the beverage will change from transparent to milky: this is the well-known 'Ouzo effect'. But what will happen if you simply place a drop of ouzo on a surface and wait? Scientists have studied the phenomena taking place, and distinguish four 'life phases' of the drop, within no more than a quarter of an hour.

Inverted Cereal Effect


How your breakfast cereal has some physics in it....a combination of surface tension, gravity and good cereal like Cheerios (better than Fruit Loops)

Read about it on New York Times:

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.

Biophysics of Superheroes

Thank you for visiting this thing that could be called a blog or aggregate of suface tension material.  I am a biophysicist by training but superhero enthusiast by hobby.  I have combined these two to learn how biophysically relevant are superheroe powers and if not could they be?  I would like to disseminate it to people and I have started writing the book.  If you are interested in hearing about the release date and some of the content please let me know in the comments.  If you have any good ideas I would love to know about them.
