Cellulose is expected to have a key role in the sustainable society in the future. This natural polysaccharide can be used as alternative raw material to petrochemical products. Cellulose based functional materials can be modified to desired applications by changing their physicochemical properties. Chemical and/or biochemical reactions have so far been used to modify chemical groups on cellulo...

In mixtures of trichloroacetate ion and trichloroacetic acid in acetonitrile, trichloromethyl radicals are produced as a result of the redox reaction between the acid and its conjugate base. The reaction follows a loop mechanism in which the trichloroacetic acid is slowly consumed by proton reduction while the trichloroacetate ion is oxidized like in an electrochemical Kolbe reaction. The hydro...

Theoretical studies of the possibility of producing ammonia electrochemically at ambient temperature and pressure without direct N2 dissociation are presented. Density functional theory calculations were used in combination with the computational standard hydrogen electrode to calculate the free energy profile for the reduction of N2 admolecules and N adatoms on transition metal nanoclusters in...

We have developed a hydrogel-based microstamp device that internally contains an electrochemical system for controlled supply of reactive ink to the stamp surface. An agarose stamp was combined with a microelectrode system for the controlled supply of HBrO by an electrochemical reaction. The supplied HBrO will detach the heparin layer pre-coated on substrates and allow selective adsorption of p...

The electrochemical behavior of quinoline in anhydrous liquid ammonia was investigated by cyclic voltammetry and controlled potential coulometry. In the absence of added alkylating agent, quinoline is reduced in two steps to yield the radical anion and dianion both of which undergo further chemical reaction. The radical anion species dimerizes to form the dimeric dianion which is stable in the ...
