Maple surface oxidation

Sugar maple was reacted with propylene and butylene oxide (Rowell etal., 1982). The modulus of elasticity (MOE) and modulus of rupture (MOR), fibre stress at proportional limit, and maximum crushing strength all exhibited a reduction, compared to unmodified samples. Nilsson and Rowell (1983) reacted ponderosa pine with butylene oxide and exposed the wood in an unsterile soil decay test. At low WPGs, severe surface decay due to soft rot and tunnelling bacteria was observed. Such attack was reduced at 15 % WPG,... 

Potentiometric techniques have been used to study autonomous reaction rate oscillations over catalysts and carbon monoxide oxidation on platinum has received a considerable amount of attention43,48,58 Possible explanations for reaction rate oscillations over platinum for carbon monoxide oxidation include, (i) strong dependence of activation energy or heat of adsorption on coverage, (ii) surface temperature oscillations, (iii) shift between multiple steady states due to adsorption or desorption of inert species, (iv) periodic oxidation or reduction of the surface. The work of Sales, Turner and Maple has indicated that the most... 

Vayenas et al. (J89) developed a model for ethylene oxidation on Pt based on solid-state electrolyte measurements that resembles the Sales-Turner-Maple model described in Section IV,A. However, Vayenas et al. balanced gas-phase concentrations and considered the surface coverages of only two species, namely active and inactive oxygen. Ethylene was assumed to react very rapidly, thus never reaching a significant surface coverage. This model semiquantitatively reproduced the experimentally observed behavior.
