the iranian scientist of the german max planck foundation succeeded in presenting a method to place a single nanoparticle on the surface of the cell, which opens a new path for the study of cell biology and medicine. in this method, a piece of material is placed on the surface of the cell with two laboratory tools. this affordable and relatively cheap way to create new opportunities in science. text and presentation new treatment methods. according to the researchers, these two tools act like a brush and move the created drop slowly around the cell and transfer the desired substance to the cell like a toothbrush or combing. isfahani engineers designed and produced high-capacity liquefied natural gas tanks. by using these reservoirs , power plants can get excess gas. store in the hot months of the year and use in the cold season. thanks to the efforts of danesh banyan corporate researchers in isfahan province of iran , he achieved the knowledge of designing and producing double-walled liquid natural gas tanks. anji is a knowledge it is an advanced technology that was available to a few
