  • Studies on the cyclisation of two key allyl phenol intermediates of bromotyrosine based natural products 
    Mallavadhani, U.V.; Narasimhan, K. (Indian Journal Of Chemistry Section B-Organic Chemistry Including Medicinal Chemistry, 42(1), 2003: 199-201)
    Cyclisation of two key allyl phenol intermediates viz. 2-allyl-6-bromo-4-formyl phenol 1 and 4-acetyl-2-allyl-6-bromo phenol 2 has been studied under a variety of acid catalysts. While mineral and organic acids did not ...
  • Dissolution studies on Cu-Ni-Co-Fe matte obtained from manganese nodules 
    Si, S.; Anand, S.; Nam, C.W.; Park, K.H.; Das, R.P. (Proceedings Of The Fifth (2003) Isope Ocean Mining Symposium, 2003: 231-237)
    Recovery of Cu, Ni and Co from Manganese Nodules can be achieved either through a hydrometallurgical route or through a combination of pyro-hydrometallurgical route. With a view to pursue the second option, synthetic ...
  • Raw materials and processing techniques for advanced ceramics and Indian scenario 
    Singh, B.P.; Bhattacharjee, S.; Besra, L.; Sengupta, D.K.; Misra, V.N. (Transactions Of The Indian Institute Of Metals, 56(2), 2003: 141-154)
    Raw materials are important for advanced ceramics. The performance of advanced ceramics primarily depends on the quality of raw materials. In the development of advanced ceramics, extraordinary control of the raw materials ...
  • Effect of anions on the textural and catalytic activity of titania 
    Samantaray, S.K.; Parida, K.M. (Journal Of Materials Science, 38(9), 2003: 1835-1848)
    An attempt has been made to review and studied the effect of ions ( phosphate and sulfate) on titania samples. Surface area, average pore diameter and total pore volume increases however crystallite size decreases with ...
  • Geochemistry of trace elements in the ground water of Cuttack City, India 
    Das, J. (Water Air And Soil Pollution, 147(1-4), 2003: 129-140)
    The concentration of some trace metals, like Fe, Mn, Cu, Pb, Zn, Co, Cr and Ni, was measured in the potable water of Cuttack City, India during winter, summer and rain events in the course of a two year period. Apart from ...
  • Enhancement in the microhardness of arc plasma melted tungsten carbide 
    Nayak, B.B. (Journal Of Materials Science, 38(12), 2003: 2717-2721)
    Microhardness is found to increase significantly in arc plasma melted tungsten carbide. To understand the mechanism for such increase, tungsten carbide powder was mixed with tungsten metal powder to prepare mixtures of ...
  • Hydrology and assessment of lotic water quality in Cuttack city, India 
    Das, J.; Acharya, B.C. (Water Air And Soil Pollution, 150(1-4), 2003: 163-175)
    A total of 120 water and sewage samples were collected from 20 stations over six consecutive seasons in two years in order to study the possible impact of domestic sewage on the lotic water in and around Cuttack, India. A ...
  • Leaching of low grade Joda manganese ore with sulphur dioxide in aqueous medium 
    Naik, P.K.; Nathsarma, K.C.; Das, S.C.; Misra, V.N. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 112(2), 2003: C131-C134)
    The feasibility of recovering manganese by leaching low grade ore with aqueous sulphur dioxide has been investigated. Successful extraction ivas achieved at atmospheric pressure and room temperature. The concentration of ...
  • Leaching of manganese nodule in hydrochloric acid in presence of sphalerite 
    Madhuchhanda, M.; Devi, N.B.; Rath, P.C.; Rao, K.S.; Paramguru, R.K. (Canadian Metallurgical Quarterly, 42(1), 2003: 49-59)
    This paper reports the results of hydrochloric acid leaching of manganese nodule and sphalerite in combination. Combined leaching was observed to be more effective than the individual leaching of either sphalerite or nodule. ...
  • Isopropylation of benzene over sulfated ZrO2-TiO2 mixed-oxide catalyst 
    Das, D.; Mishra, H.K.; Dalai, A.K.; Parida, K.M. (Applied Catalysis A-General, 243(2), 2003: 271-284)
    Zirconia-titania mixed oxide containing 60 mol% of zirconium was synthesized by co-precipitation method with and without sodium dodecyl sulfate (SDS) as surfactant. The 110 degreesC dried mixed oxides were loaded with 10 ...
