Membranes with nanoscale pores have high potential in modern battery and energy conversion applications as well as water treatment. The characterisation of such samples regarding their pore structure is of vital importance for their performance.
Download this report which shows the characterisation of a 100 nm thick porous polymer membrane with a pore structure that is perpendicular to a silicon substrate surface.
Radio wave weapon knocks out drone swarms
I hope they have assessed how easy it is to shield a drone against the attack. Hopefully the shielding would add too much weight.
