87 Student Researchers

Statement of the Problem

The aggressive exploitation of fossil fuels and other natural resources has contaminated the air we breathe, the water we drink, and the land we inhabit. Over a million tons of carbon (iv) oxide 3 and other climatically-important “greenhouse” gases have already been accumulated in the atmosphere (Arpin and Veaweb, 2007). Within the course of a relatively short time, the concentration of carbon (iv) oxide, CO2, has increased by 40%, and now exceed...

11. MODIFICATION OF STAINLESS STEEL SURFACES FOR ADVANCED FUNCTIONALITIES

87 Student Researchers

SUMMARY

In industry, business, and homes worldwide, metal alloys called stainless steels are used extensively. Stainless steel is a generic term for a large family of iron-based alloys containing a minimum of 10.5% chromium content by weight. The primary alloying element, chromium, forms a thin passive layer of chromium oxide/hydroxide when exposed to air and moisture, which is dense and impervious to water and air, thereby protecting the bulk metal beneath the surface layer. Stainl...

13. KINETICS AND RHEOLOGICAL BEHAVIOUR OF WASHABLE PAINTS FROM PALM KERNEL AND JATROPHA SEED OILS

87 Student Researchers

Statement of the Problem

Toxic paints still dominate the local market, and as such, these paints are mostly used because they are cheap and readily avaliable. The few available non-toxic paints (washable paint) are sold at high price because the major raw materials are not locally sourced. The behaviours of some of the available washable paints under certain conditions are yet to be established. This research will make use of locally sourced oil to produce and study the behaviour of...

Statement of the problem

One of the major reasons for food shortage is the unavailability of adequate preservation facilities. Some of the food crops are seasonal, being readily available during some periods of the year and scare during other periods due to inefficient preservation. Potato and cocoyam, though very nutritious, easily deteriorates due to the high moisture content they contain which favors the growth and activities of micro-organisms. Drying is one of the ways of...
