Applicability of four recent models to the discharge behaviour of different phases of MnO2 in alkaline and acidic/neutral electrolytes

Desai, B.D.; Dhume, R.A.S.; Kamat-Dalal, V.N. (Journal of Applied Electrochemistry. 18(1); 1988; 62-74.)

Manganese dioxides belonging to different crystalline phases were discharged in 9 M KOH and 5 M NH4Cl+2 M ZnCl2 at a constant current of 1 mA 0.1 g. These phases were characterized by X-ray diffractometry and chemical ...
Impedance measurements on some doped mno2 electrodes in H2SO4 electrolyte

Desai, B.D.; Lobo, F.S.; Kamat-Dalal, V.N. (Journal of Applied Electrochemistry. 24(9); 1994; 917-922.)

A.c. impedance behaviour of beta-MnO2 and doped beta-MnO2 electrodes in H2SO4 medium was assessed with a view to explaining the mechanism of the discharge behaviour of MnO2 electrodes in 4 m H2SO4 electrolyte. The electrodes ...
Optimization of synthesis of nickel-zinc-ferrite from oxalates and oxalato hydrazinate precursors

Moye, V.; Rane, K.S.; Kamat-Dalal, V.N. (Journal of Materials Science-Materials in Electronics. 1(4); 1990; 212-218.)

Ferrites, Ni(x)Zn(1−x) Fe(2)O(4) are being synthesised by five different methods, namely (a) autocatalytic decomposition and air sintering of mixed-metal oxalato hydrazinate prepared by a solution method, (b) decomposition ...
Performance and discharge characteristics of doped (beta)-MnO2 in H2SO4 electrolyte

Desai, B.D.; Lobo, F.S.; Kamat-Dalal, V.N. (Journal of Power Sources. 51(3); 1994; 351-365.)

Doped manganese dioxides (beta-Mno2) were prepared by thermal decomposition (180-degrees-C) of manganese nitrate in the presence of weighted quantities of NH4VO3, Na2WO4.2H2O, LiNO3, AgNO3 or MoO3. Detailed chemical analyses, ...
Performance and discharge characteristics of doped beta-MnO2 in ZnCl2 electrolytes

Desai, B.D.; Lobo, F.S.; Kamat-Dalal, V.N. (Journal of Power Sources. 51(3); 1994; 331-349.)

The electrochemical performance of a number of doped MnO2 samples was evaluated in the following electrolytes: (i) Leclanche; (ii) 25 percent ZnCl2, and (iii) 25 percent ZnCl2 with additives i.e., 2 percent LiCl and 1 ...
Preparation and Characterization of Some Transition Metal Oxides (Investigations on Cuprate Superconducting Systems)

Anvekar, Tushar Shamba
Proc. 9. Nat. Workshop on Thermal Analysis

Budkuley, J.S.; Kamat-Dalal, V.N.; Dharwadker, S.R.. Ed. (1993; Require pagination (from-to))
Synthesis and decomposition of ferrous oxalato hydrazinate precursors to obtain magnetic oxides

Borker, V.; Rane, K.S.; Kamat-Dalal, V.N. (Journal of Materials Science-Materials in Electronics. 4(3); 1993; 241-248.)

The preparation of gamma-Fe2O3 from the thermal decomposition of ferrous oxalate dihydrate and ferrous oxalato hydrazinate precursors was studied employing differential thermal analysis (DTA), X-ray diffraction (XRD), ...
