For decades, the engineers who design industrial filters have lived with an uncomfortable compromise: push more liquid through a membrane and it clogs faster, slow it down and it lasts longer. Sumitomo Chemical, working alongside researchers at Kobe University, has now reframed that compromise by looking not at the size of a membrane's pores, but at how those pores are arranged in three-dimensional space. Their newly developed alumina material increases the density of through-running pores, spreading flow across more pathways and reducing the accumulation of contaminants — achieving more than
