Inorganic Pores Maintain Flexible Attitude
Molybdenum oxide-based porous capsules sound like something rigid, but researchers have found one that adapts to circumstance. Achim Müller of the University of Bielefeld, in Germany, earlier assembled 3-nm-diameter spheres from molybdenum oxide rings (which act as the pores), pentagons, and linking groups. When Ira A. Weinstock of Ben Gurion University of the Negev, in Beer Sheva, Israel, and coworkers resynthesized the capsules and studied their properties, they found that carboxylates larger than the pores . . .
