Packaging affects the properties of water

28.09.2013

Scientists at the Georgia Institute of Technology have found that the properties of the pipeline material affect the viscosity of water. True, this is noticeable only at the nanolevel.

The phenomenon does not affect the speed at which water pours out of the bottle, but at the nanoscale, under specific conditions, differences in the behavior of water are clearly visible. A new study shows that in nanoscopic glass channels, the viscosity of water can be twice as high as in plastic channels. Simply put, in nanoscale glass channels, water behaves like a ketchup-thick liquid.

At first glance, this discovery is of little use, but in fact it is very important, especially in light of the spread of nanotechnologies, such as microfluidic chips, designed to instantly diagnose infectious diseases. In addition, this information is important for developers of micromechanical systems, ultra-precise 3D printers and other devices where liquids have to be forced through tiny holes.

Changing the viscosity of water is another example of amazing phenomena at the nanoscale. It has long been known that the so-called hydrophilic materials attract water molecules and impede their movement, while hydrophobic materials, on the contrary, make it easier. But at the macro level, this is not so noticeable, but at the nano level, when water moves in a layer of only a few molecules, the viscosity increases sharply due to the fact that water molecules “stick” to the hydrophilic surface and move in a closer group.

The researchers studied the behavior of water at the nanoscale on various types of surfaces: mica, graphene oxide, silicon, diamond-like carbon and graphite. Mica, used in the drilling industry, and at the nanoscale, turned out to be the most hydrophilic material, while graphite was the most hydrophobic.

Scientists believe that a sharp increase in viscosity on hydrophilic surfaces will be observed for other liquids, not just water. Thus, developers of miniature machines, metamaterials, nanostructured materials, etc. this factor should be taken into account.

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>
