С помощью World Community Grid (добровольная сеть распределенных научных вычислений, которая использует компьютеры волонтеров когда те простаивают и в которой я участвую уже несколько лет) сделали важное открытие в области нанотехнологий, позволяющее осуществлять эффективную фильтрацию воды с помощью карбоновых нанотрубок:
Fundamentally, our discovery is about how we can potentially use carbon nanotubes to make water filters that are more efficient and less expensive. Carbon nanotubes are made of single-atom-thick sheets of carbon atoms, called graphene, rolled up into tiny tubes, with diameters of just a few nanometers - one ten-thousandth the diameter of a human hair. The size of the tubes allows water molecules to pass through, but blocks larger pathogens and contaminants, purifying the water. They are so small that the scientific community initially expected that water would move through them too slowly to be useful. However, earlier experiments showed that water sometimes passes through them much more easily than expected.
Increased flow could mean a more efficient filter, but due to lack of sufficient computing power, until now there had been a wide gap between what scientists could understand from computer simulations, and what they could actually measure in experiments. Our research efforts focused on bridging this gap. By running massive computer simulations on World Community Grid with your help, we discovered that certain kinds of natural vibrations called phonons, under specific conditions, can lead to a 300%+ increased rate of diffusion (a kind of flow) of water through carbon nanotubes, compared to previous theoretical predictions. Importantly, since these tiny vibrations occur naturally due to thermal (heat) energy inherently stored in all materials, no external energy source is required to take advantage of this phenomenon.
What does this discovery mean for future research? The immediate application is in using the new insights from our simulations to design more efficient water filters. If experiments confirm our predictions, such filters could help improve access to clean water for millions of people worldwide. Our predictions may also lead to a less expensive method for desalinating water (the process of obtaining fresh water from sea water).
