Temperature effect on the electrical properties of pyrolytic MnO2 thin films prepared from Mn(C2H3O2)2·4H2O

Farid ul Islam, A.K.M.; Islam, R.; Khan, K.A.; … - In: Renewable Energy 32 (2007) 2, pp. 235-247

Spray deposited MnO2 thin films onto glass substrate were subjected to a post-deposition heat treatment and the effects of temperature on electrical transport properties were studied in details. The heating and cooling cycles of the samples are reversible after successive heat-treatments in air...

Non-Debye screening in a formally consistent version of the modified mean spherical approximation

Varela, L.M.; Garcı́a, M.; Mosquera, V. - In: Physica A: Statistical Mechanics and its Applications 311 (2002) 1, pp. 35-49

The non-Debye decay length of ionic solutions (κ) is analyzed combining the dressed ion theory route with a new version of the modified mean spherical approximation (MMSA) [Varela et al., J. Chem. Phys. 109, 1930 (1998)]. Seeking formal consistency, the MMSA short-range direct correlation...
