The synthesis of N-heteroaryl substituted benzene sulphonamides and evaluation of their biological activities are reported. Synthesis was achieved by the reaction of benzene sulphonyl chloride and substituted amino heterocycle in dry pyridine. The structures of synthesized compounds were assigned by spectroscopic methods. The eight (8)… Continue Reading
The removal of Pb(II) ions from aqueous model solution using zeolite has been investigated under different operational parameters like heavy metal ion concentration, adsorbent amount and particle size. The zeolite used was synthesized and characterized using SEM and XRD analysis. The equilibrium adsorption capacity of zeolite used for… Continue Reading
A simple and sensitive spectrophotometric method for the determination of paracetamol was explored, using zirconium(IV) and vanadium(V) oxides. The method was based on the oxidation of paracetamol by zirconium(IV) and vanadium(V) in alkaline and acidic media respectively. The stoichiometric studies indicated a mole-ratio of 1:1 for the… Continue Reading
The original tectonic setting of the mafic and ultramafic rocks of the megatectonic line of Darno are investigated using evidence provided by their major elements and trace element contents, … Continue Reading
ABSTACT Palmprint recognition has been investigated over ten year years. Palmprint is proven to be distinguishable from other features because of number of attributes. These attributes include color, clarity, position, continuity, length and variation in thickness. Lines are represented in a very efficient way and it needs low storage and… Continue Reading
Scale formation has become a big burden to sugar manufacturing industries, especially in evaporators, this is because of the characteristics of cane juice which is allowed in evaporators. Evaporators are used to evaporate as much water as possible from the juice using exhaust steam from the powerhouse as the heating medium so as to… Continue Reading

The effectiveness of Terminalia catappa (tropical almond) and Tamarindus indica (tamarind) as corrosion inhibitors for stainless steel in 1M hydrochloric acid at 30°C, 40°C and 50°C was investigated in this research. The gravimetric method of analysis was employed for 20 days at a 4-day interval using 0.9, 1.1 and 1.3g/15mL of… Continue Reading
Biodiesel is a renewable fuel that will soon be fully accepted in the commercial world but there are limitations to its use that need improvement. The use of oxygenated additives have improved the burning/fuel qualities of conventional diesel and gasoline. These oxygenates may also improve the qualities of biodiesel. This paper focuses on… Continue Reading
This research involves the application of pyrolysis has been viewed as an efficient means for the proper disposal of waste plastics in the environment amongst others. In this research, the influence of two catalysts namely; Zeolite and Titanium (IV) oxide are examined. Zeolite as a catalyst has obtained approval due to its ability to… Continue Reading
Biodiesel is a biodegradable, environment friendly, renewable and energy efficiency fuel. It is becoming the most prominent alternative to petro-diesel. Due to current environmental concerns, quality and properties of biodiesel have to be optimized to remove its limitations. The use of oxygenates additives have proved to play such… Continue Reading
Concrete is used widely in all types of construction. In particular, it is the first choice material for the construction of various industries, due to its affordability, durability, heat resistance, strength, etc. Based on this, understanding the response of concrete structural components for all types of loading is crucial to the… Continue Reading
A theoretical study of the production of Technetium-99m (99mTc) using a cyclotron has been conducted. A nuclear reaction model code (Talys code) was used to generate reaction cross sections as functions of particle energies for 100Mo (p, 2n)99mTc reaction channel which would lead to the direct production of 99mTc. Excitation function for… Continue Reading

Globally, human health is under threat due to the presence of diseases caused by microorganisms such as bacteria and viruses. Bacteria are found on almost all surfaces with which people come into contact and therefore pose a threat to human health. Antimicrobial resistance is a major health concern as these microorganisms can cause… Continue Reading
This purpose of this experiment was to characterize wild strains of yeasts from different sources from north eastern Nigeria that have unique traits that will be applicable in the bioethanol production industry. The yeast characterization of these yeast strains were based on the yeast strain ability to grow at different temperature… Continue Reading
The antibacterial activity of plant extracts compared to a known antibiotic (ampicillin) was evaluated against ten gram-negative and gram-positive bacteria which can infect humans.
