The encapsulation of polyoxometalates within the large pores of the Zr(iv) biphenyldicarboxylate UiO-67 metal-organic framework has been achieved, for the first time, by direct solvothermal synthesis. The resulting POM@UiO-67 composite materials were fully characterized by XRPD, IR, MAS NMR, N2 porosimetry measurements and cyclic voltammetry.
I present Quillen’s proof of the fact that the K-groups KiA where A is the ring of integers in a number field F are finitely generated. This talk was given in the Algebraic K-theory seminar at Michigan during the Winter semester of 2015.
Representations of space in the social sciences are remarkably dependent on images of break, rupture and disjunction. The distinctiveness of societies, nations, and cultures is predicated on a seemingly unproblematic division of space, on the fact that they occupy “naturally” discontinuous spaces.
