We present a method for quantifying the kinetic current of the hydrogen oxidation reaction (HOR) on Pt in acidic media using the adsorption and activation free energies as the intrinsic kinetic parameters. Our approach involves deriving the HOR inter

A method of measuring error-free potentials of individual electrodes directly in the polymer electrolyte fuel cell and under a full range of load is introduced. Successful measurement is accomplished by placing a reference electrode in ionic contact

If G is a group and $\sigma$ an automorphism of G, one has the twisted conjugation action of G on itself $((g,h)\mapsto gh(\sigma g)^{-1}).$ This paper collects a number of results — more or less well known — for the case that G is a simply conne

An algebraic group of type E7 over an algebraically closed field has an irreducible representation in a vector space of dimension 56 and is, in fact, the identity component of the automorphism group of a quartic form on the space. This paper describe

The symmetric varieties considered in this paper are the quotientsG/H, whereG is an adjoint semi-simple group over a fieldk of characteristic ≠ 2, andH is the fixed point group of an involutorial automorphism ofG which is defined overk. In the case

Cellular adhesion through the β2 integrin lymphocyte function-associated Ag (LFA)-1 is a complex event involving activation, ligand binding, and cell shape changes that ultimately result in enhanced adhesion. In this report we define requirements fo

Methanol and water absorption in 1100 and 1200 e.w. Nafion® membranes was determined by weighing P 2 O 5 dried and methanol solution equilibrated membranes. Both methanol and water absorption in the 1200 e.w. membrane is about 70-74 % of that in the
