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....

Researchers at MIT and elsewhere have developed a new way of driving fluid droplets across surfaces in a precisely controlled way.

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.

Reducing Runoff Pollution by Making Spray Droplets Less 'Bouncy'

Reducing Runoff Pollution by Making Spray Droplets Less 'Bouncy'



Pretty much what Kibron's AquaPi has been helping companies that make pesticides do for years.  Overall by making better droplets from measuring the surface tension there will be less pesticides in the air is better for bees and trees.

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

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.

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.

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.

Drug Delivery Device Increases Efficacy, Reduces Side Effects

Drug Delivery Device Increases Efficacy, Reduces Side Effects: Chemotherapy often comes with powerful side effects. But one possibility for reducing these side effects may be if the chemotherapy drugs only become toxic when they reach the tumor.  Vibrating the capsule reduces the surface tension and allows the material to mix.
