The Moscow Power Engineering Institute has found a way to reduce the evaporation time of water by 95%. Graphene nanoflakes were used for this purpose. This was reported by the press service of the Russian Science Foundation (RSF).
The combination of water and graphene flakes can serve as a good working fluid capable of absorbing a wide range of wavelengths for direct conversion of solar radiation into thermal energy. The data we obtained will solve many applied problems in areas such as solar energy and traditional thermal systems.
Research has shown that the two-dimensional material particles absorbed visible green light and infrared radiation, which account for the peak intensity of solar radiation. This accelerated the process of water evaporation in the graphene nanofluid by 95%. In addition, sunlight was converted into heat 48% more efficiently. The development is planned to be used in the creation of energy storage and water desalination systems.
Earlier www1.ru reported that in Moscow they proposed using gelatin for flexible electronics.
