Platinum is a widely used precious metal in many catalytic nanostructures. Engineering the surface electronic structure of Pt-containing bi- or multimetallic nanostructure to enhance both the intrinsic activity and dispersion of Pt has remained a challenge. By constructing Pt-on-Au (Pt∧Au) nanostructures using a series of monodisperse Au nanoparticles in the size range of 2–14 nm, we ...

Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it from the molecular formula (Figure 1b). The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons.
(b) H3PO2 and H3PO3 act as as good reducing agents while H3PO4 does not. (c) On addition of ozone gas to KI solution, violet vapours are obtained. 3. 24. The decomposition of N2O5(g) is a first order reaction with a rate constant of 5 x 10-4 sec-1 at 45o C. i.e. 2N2O5 (g) 4NO2 (g) + O2 (g).

Phosphorous acid is the compound described by the formula H 3 PO 3.This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. . Phosphorous acid is an intermediate in the preparation of other phosphorus c
Its action is rapidly terminated by hydrolysis with AChE via the serine hydroxyl in the catalytic triad of AChE.2 The 3-dimensional structure of AChE reveals an active center located at the base of a narrow gorge about 20 Å in depth.4 The active center includes the following sites (Fig. 2): (a) the catalytic triad: Glu 334, His 447, and Ser ...

The local structure and orientational and dynamic properties are studied. It is shown that at low enough temperatures there is a well-defined orientational ordering of the water molecules. At high local densities corresponding to the maxima of the density distribution function, the water molecules are oriented parallel to the axis of the tube.
