in ▁for ▁the ▁Digital M icro graph ▁software . ▁This ▁plug - in ▁enables ▁the ▁widely ▁used ▁software ▁package ▁to ▁collect ▁pre cess ion ▁electron ▁diff raction ▁patterns ▁without ▁additional ▁modifications ▁to ▁the ▁mic ros cope . ▁ ▁According ▁to ▁N ano ME G AS , ▁as ▁of ▁June , ▁ 2 0 1 5 , ▁more ▁than ▁ 2 0 0 ▁publications ▁have ▁re lied ▁on ▁the ▁technique ▁to ▁solve ▁or ▁cor ro bor ate ▁cry stal ▁structures ; ▁many ▁on ▁materials ▁that ▁could ▁not ▁be ▁solved ▁by ▁other ▁conventional ▁cry stal log raph y ▁techniques ▁like ▁x - ray ▁diff raction . ▁Their ▁retro fit ▁hardware ▁system ▁is ▁used ▁in ▁more ▁than ▁ 7 5 ▁labor ator ies ▁across ▁the ▁world . ▁ ▁App lications ▁ ▁Cry stal log raph y ▁ ▁The ▁primary ▁goal ▁of ▁cry stal log raph y ▁is ▁to ▁determine ▁the ▁three ▁dimensional ▁arrangement ▁of ▁atoms ▁in ▁a ▁cry st all ine ▁material . ▁While ▁histor ically , ▁x - ray ▁cry stal log raph y ▁has ▁been ▁the ▁pre domin ant ▁experimental ▁method ▁used ▁to ▁solve ▁cry stal ▁structures ▁ab ▁init io , ▁the ▁advantages ▁of ▁pre cess ion ▁electron ▁diff raction ▁make ▁it ▁one ▁of ▁the ▁preferred ▁methods ▁of ▁electron ▁cry stal log raph y . ▁ ▁Sym met ry ▁determ ination ▁ ▁The ▁symmetry ▁of ▁a ▁cry st all ine ▁material ▁has ▁prof ound ▁impact s ▁its ▁emer gent ▁properties , ▁including ▁electronic ▁band ▁structure , ▁elect romagnet ic ▁behavior , ▁and ▁mechanical ▁properties
