One of the most basic things that we learn when growing up is that water can exist in 3 different states of matter: as a gas (water vapor), as a liquid (water… water), and as a solid (ice). This basic and fundamental concept has recently been turned upside down as scientist have discovered that water might also exists in a fourth state; liquid water it appears might actually come in two different states. A collaborative team of researchers led by Dr. Laura Maestro at Oxford University, found that the physical properties of water changed their behavior between 50 and 60℃ potentially changing to a second physical state of water.
As 2016 winds to a close, and in the spirit of the holiday season behold the world’s smallest snowman, measuring in at 3 microns. To put that into perspective, the smallest grains of sands are approximately 60 microns.
This creation is the work of Canadian nanotechnologists from the Western Nanofabrication Facility. The snowman is made from three ~1 micron silica spheres stacked using electron beam lithography. The eyes and mouth were cut with a focused ion, beam while the arms and nose were sculpted with platinum.
A cool feel good story to round off 2016 as we head into 2017. Happy New Year all!
