"removed chemical impurities incorporated during initial production without negatively impacting 3D nanoarchitectures... without destroying morphology... finely focused electron beam splits gas molecules, solidifies and adhere them using special gases under vacuum, controlling beam movements and exposure times produce in 1 step lattice building blocks, then stacking them... high purity 3D architectures with individual features smaller than 10 nm, solar cells and biological, chemical sensors, optical tweezers"
