The Niger Delta region of Nigeria is richly endowed with both renewable and non-renewable natural resources. It contains 20 billion of Africa's proven 66 billion barrels of oil reserves and more than 3 trillion cubic meters of gas reserves. Oil and gas resources of the Niger Delta account for over 85% of the nation's gross domestic product (GDP), over 95%(More)
The characterization of single crystals often involves working with very small samples because of natural size limitations and the difficulties involved in the synthesis of large single crystals. The measurement of the thermal conductivity of small samples has been a formidable challenge for many years due to the low thermal conductance and the low(More)
The thermopower, resistivity and thermal conductivity of NaCo/sub 2/O/sub 4/ single crystals which were grown by typical NaCl flux method were measured by our custom designed systems. A novel low temperature flux method where NaCl/NaOH was used as flux and metallic Co powders as Co source was developed to successfully synthesize Na-deficient Na/sub x/Co/sub(More)
