Antifouling activities of octocorals on some marine microfoulers

Wilsanand, V.; Wagh, A.B.; Bapuji, M. (Microbios, 104(409), 2001: 131-140)

The antifouling activities of vacuum-dried 70% aqueous alcohol extracts of four gorgonian and five soft corals against four dominant marine fouling diatoms (Navicula subinflata Grun, N. crucicula Smith, Amphora so., Nitzschia ...
Butane isomerization over persulfated zirconia

Mishra, H.K.; Dalai, A.K.; Parida, K.M.; Bej, S.K. (Applied Catalysis A-General, 217(1-2), 2001: 263-273)

A study on n-butane isomerization reaction over persulfated zirconia was performed under atmospheric pressure varying pretreatment gas, butane diluents, concentration of butane, contact time and reaction temperatures. It ...
Growth inhibition of fouling diatoms by antipatharian colonies

Wilsanand, V.; Wagh, A.B.; Bapuji, M. (Microbios, 106, 2001: 41-50)

Growth inhibition of four dominant marine fouling diatoms by alcohol extracts of antipatharian colonies, collected off the east coast of India, are reported here. Of the three antipatharian colonies tested one antipatharian ...
Recovery of magnetite fines from sponge iron sludge and preparation of colloidal magnetite from hematite fines by precipitation in presence of poly vinyl alcohol

Das, B.; Prakash, S.; Reddy, P.S.R. (Transactions Of The Indian Institute Of Metals, 54(3), 2001: 91-98)

Two waste materials viz., sludge and iron ore fines generated at a sponge iron plant were taken up with a view to utilize the same. The recovery of magnetite fines from the sludge was studied by using the conventional ...
Sequential leaching of trace elements in coal: A case study from Talcher coalfield, Orissa

Mohanty, J.K.; Misra, S.K.; Nayak, B.B. (Journal Of The Geological Society Of India, 58(5), 2001: 441-447)

The extent of vaporisation and subsequent condensation of many trace elements during coal combustion is largely dependent upon the mode of occurrence of the trace elements, besides many other parameters, Mode of occurrence ...
Transfer of nickel from sodium sulphate solutions to the spent electrolyte through solvent extraction and stripping

Reddy, B.R.; Sarma, P.V.R.B. (Hydrometallurgy, 60(2), 2001: 123-128)

Studies on the separation of nickel from concentrated solutions containing sodium sulphate were carried out with di(2-ethylhexyl) phosphoric acid diluted with kerosene (mostly aliphatic). Increase in extractant concentration, ...
Ionic mass transfer at a vibrating electrode support in an electrowinning cell

Ravi, P.; Ravan, N.; Krishna, P.G.; Venkateswarlu, P. (Hydrometallurgy, 60(1), 2001: 69-79)

Limiting current data were measured on an electrode support vibrating horizontally in an electrowinning cell. Four copper strip electrodes were fixed flush with the surface of the electrode support and limiting current ...
Study on the various factors affecting the quality of precipitated non-metallurgical alumina trihydrate particles

Pradhan, J.K.; Gochhayat, P.K.; Bhattacharya, I.N.; Das, S.C. (Hydrometallurgy, 60(2), 2001: 143-153)

Processes for production of superfine white alumina trihydroxide (ATH) powders from actual plant Bayer liquor have been developed for use in non-metallurgical applications. The specialty grade hydroxides suitable for ...
Mossbauer studies of cation distribution in natural chromites from Boula-Nausahi igneous complex, Keonjhar district, Orissa, India

Verma, H.C.; Mohanty, J.K.; Tripathi, R.P. (Journal Of Alloys And Compounds, 326(1-2), 2001: 132-136)

Mossbauer spectroscopic studies of the natural chromites obtained from four iron ore bands in the Boula-Nausahi igneous complex are presented. The results are quite different from those obtained for the. natural chromites ...
Influence of perchloric acid on the kinetics of immersion plating of copper onto aluminium

Kanungo, M.; Chakravarty, V.; Mishra, K.G.; Das, S.C. (Hydrometallurgy, 61(1), 2001: 1-11)

The effect of perchloric acid on the kinetics of immersion plating of copper onto aluminium from a bath containing complexing agent over a range of concentration of copper (0.382-2.55 g dm(-3)) and perchloric acid (0.255-0.590 ...
