ABSTRACTThis study investigated the use of information and communication technology (ICT) as antidote in learning difficulty in chemistry in Ilesa-East L.G.A of Osun state.100 students and 30 teachers were randomly selected for the study.The instruments used for collecting information were teachers’ and students’ questionnaires. Data collected were analyzed using Chi-square statistic. The results revealed that:1. There is a significant difference between teaching guide in chemistry and th...
1.0 INTRODUCTION Daturastramoniumis an annual herb, with stem erect and spreading branches above. It is common in the waste land, fields and gardens in Baghdad district. Leaves, seeds and roots contain the alkaloid daturine (a mixture of the two alkaloids hyoscyamine and atropine) and also contain scopolamine alkaloid (Hyosine) acids, tannin and fatty oil. Plants are rich source of secondary metabolites with interesting biological activities (Palombo and Semple, 2001; Koduruet al., 2006)...
ABSTRACTThis paper examines the hydrochemical facies of groundwater present in the shallow marine Plain Sands aquifer of Udi and its immediate environs, maps their areal distribution and attempts to explain the controlling processes responsible for the various facies. 12 water samples were collected from wells tapping the shallow marine Plain Sands aquifer of Udi and environs and analyzed for various parameters including pH, total dissolved solids (TDS), K, Na, Ca, Mg, Cl, NO3, Fe, Pb, TH, Ac...
AbstractF-Sulfo Fatty Methyl Esters sulfonates (F- MES) are new anionic surfactants obtained via sulfoxidation of fatty acid methyl esters (FAME) with SO2, O2, and ultraviolet light of appropriate wavelength. The designation of Φ refers to the random positioning of SO3 in...

ABSTRACTThe toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy metals (chromium, copper, nickel and lead) using Atomic Absorption Spectrophotometer (AAS) after digestion with concentrated HNO3 and HCl acid...
ABSTRACTNickel amine carboxylate complexes were synthesized by reacting Ni(ii)chloride with ammonia, malonic and tartaric acid, which formed Nickel amine malonate and Nickel amine tartarate of blue and green crystal and the percentage yield are of both complexes are 62.65% and 62.83% respectively. The decomposition temperatures were 218o C and 203oC with percentage moisture content of 8.0% and 21.50%. The carboxylic acids and the synthesized complexes were tested for antibac...
ABSTRACTPhytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 ho...
AbstractThis work titled The Role of Chemistry Teacher in the Development of Science Education in Nigeria is specifically designed to find out and discuss the various ways science education has been lagging in Nigeria and how chemistry education can help to remedy the situation. In the course of this, some issues were discussed such as the concept of chemistry, chemistry education, science education, objectives of chemistry education, problems facing science education in Nigeria and way...
INTRODUCTION Chemistry is one of the essential science subjects. According to Oxford Advanced Learners Dictionary (2008), chemistry is the branch of science that deals with the composition and properties of substances and various elementary forms of matter. Mifflin (2011) defined chemistry as the science of the composition, structure, properties and reactions of matter especially of atomic and molecular systems. Sarah (2015) defined chemistry as a physical science and the study of the pr...
1.0 INTRODUCTIONHair coloring is the practice of changing the hair color. The main reasons for this are cosmetic, to cover gray hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair dyes generally contain dyes, modifiers, antioxidants, alkalizers, ammonia and a mixture of other compound used to impart different qualities to hair depending on the ha...
ABSTRACTCarbon –U (C-11) radiotracers are widely used for the early diagnosis of cancer, monitoring therapeutic response to cancer treatment and pharmacokinetic investigations of anticancer drugs. PET imagining permits non-invasive monitoring of metabolic processes and molecular targets, while carbon-II radiotracers allow a “hot-for cold” substitution of biological active molecules. Advance in organic synthetic chemistry and radiochemistry as well as improved automated techniques for ra...
ABSTRACTIn order to search for alternative control methods to synthetic pesticides, the potential of essentialoils from Allium sativum (L.) (Alliaceae); was evaluated as fumigants against Callosobruchus maculatus (fab.)(Coleoptera: Bruchidae), a pest that attacks pulses during storage. Chickpea seeds were infested with 10 pairsof newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essential oils of garlic/l of air. The essentialoils of garlic were analyzed by GC-MS. The major com...
