Controlling technologies of SO2 by adsorption techniques

The present studies deals with the adsorption of SO2 by manganese oxide i.e., Pyrulusite ore. Pyrulusite is used as an adsorbent for the present studies. It is found that the percentage removal of SO2 increases with the increase in contact time, follows first order kinetics and a unimolecular layer is formed during the process. The percentage removal of SO2 increases with increase in dosages an...

A Model of Irreversible Electro-Oxidation Inhibited by Either Adsorption or Surface Complexation of the Product

Theoretical models of irreversible electro-oxidation of dissolved reactant giving dissolved product on the stationary planar electrode are developed for the conditions of staircase cyclic voltammetry. In the first model it is assumed that the product is adsorbed on the electrode surface and that the adsorbate prevents the transfer of electrons. In the second model it is assumed that the electro...

Oxidation of SO2 by H2O2 on ice surfaces at 228 K: a sink for SO2 in ice clouds

The heterogeneous reaction SO2 + H2O2 → H2SO4 on ice at 228 K has been studied in a low temperature coated-wall flow tube. With H2O2 in excess of SO2, the loss of SO2 on an ice surface is time dependent with the reaction most efficient on a freshly exposed surface. The deactivation of the surface arises because the protons formed in the reaction inhibit the dissociation of adsorbed SO2. This lo...

Patterning and tuning of electrical and optical properties of graphene by laser induced two-photon oxidation.

We demonstrate a simple all-optical patterning method for graphene, based on laser induced two-photon oxidation. By tuning the intensity and dose of irradiation, the level of oxidation is controlled, the band gap is introduced and electrical and optical properties are continuously tuned. Complex patterning is performed for air-suspended monolayer graphene and for graphene on substrates. The pre...

Polymer Translocation Induced by Adsorption

We study the translocation of a flexible polymer through a pore in a membrane induced by its adsorption on trans side of the membrane. When temperature T is higher than Tc, the adsorption-desorption transition temperature, attractive interaction between polymer and membrane plays little role in affecting polymer conformation, leading to translocation time that scales as τ ∼ L3 where L is the po...
