How natural oils can be hydrogenated without making unhealthy trans fats

... Zaera's lab found that the platinum catalyst performed most selectively when its particles assumed tetrahedral shapes, with the atoms arranged in a hexagonal honeycomb lattice. Particles with these shapes allow for the preservation of the harmless cis configuration in the hydrogenated fats. Other lattic...
