This work aims at developing a rational design of graphene-oxide based filler and addresses modifications to the filler architecture in generating fillers that can adapt to the needs of additive manufacturing and lead to superior performance. Novel graphene-based fillers are synt...
The constant failing of floor finishes and the cost of repairs of residential building in the study area motivated the study. The aim of the study was to ascertain: the prevalent floor finish types used in the study area, the critical material properties of typical floor finish i...
Biogenic synthesis of silver nanoparticles (AgNPs) using plant extracts has become a promising substitute for the conventional chemical synthesis method. The present study aims to develop a simple, cost-effective, environmentally friendly method for silver nanoparticles (AgNPs) s...
Background: Thermodynamic parameters are important in determining the feasibility and spontaneity of an adsorption process. They are also vital in estimating adsorptive mechanisms (i.e., physiosorption, ion exchange or chemisorption). Accurate calculation of these thermodynamic p...
Fe-Co-2V is a popular metallic alloy used in electromagnetic applications. However, there is a lack of mechanical fatigue characterization of this alloy in the literature. In this work, Fe-Co-2V specimens with rectangular cross-sections were carefully prepared in accordance with...
Aims: The LBL technique is leveraged in this study to perform thin film fabrication using (diallyl dimethylammonium chloride) (PDDA) and copper phthalocyanine-tetrasulfonic acid (CuTsPc). The deposition of PPDA/CuTsPc films over a glass substrate through alternate adsorption is s...
Aims: A comparative study on the thermal behavior of natural rubber (NR) filled with different plant wastes and carbon black was carried out with the aim to evaluate green fillers that can replace carbon black filler in natural rubber vulcanisates for thermal applications. Study...
A bidentate Schiff base ligand having nitrogen sulphur donor atoms was derived from the condensation of S-benzyldithiocarbazate (SBDTC) with cinnamaldehyde. The ligand was then chelated with Co(II) and Sb(III). Molecular structures of the Schiff base ligand and its complexes were...
This study characterized the sizes, shape and surface properties of Nigerian cement particles and investigated how the features affect the performance of Electrostatic Precipitator (ESP), a commonly employed particulate control device. Samples of cement powder were collected acro...
Thin films of titanium dioxide (TiO2) were prepared through sol-gel routes and dip-coating technique, employing titanium isopropoxide (TTIP) in 2-propanol as precursor, and three stabilizing agents i.e. diethanolamine (DEA), lactic acid, and citric acid. The optical properties, c...
Environmental protection, public health, physical capital, and natural state, maintaining biological diversity and fragile ecosystems balance, waste management, etc. are just some of the current issues facing humanity. Waste management and hence their degree of recycling have dif...

The adsorption of lead (II) ions from fertilizer wastewater using Acid Modified Eggshell (AMES) as adsorbents was studied. The effects of process parameters such as temperature, contact time, pH and adsorbent dosage on the adsorption of Lead (II) ions from fertilizer industrial w...
This research work focused on extracting dye from the surface of dyed polyester fabric and also investigates the effect of exposing the extracted dye solution to diffused light and changes in temperature which are common processes in dry cleaning industries. This is to establish...
Aims: In this research work the viability of producing silicon carbide reinforced aluminium composite using indigenous casting technology has been investigated. Place and Duration of Study: AfDB Lab, African University of Science and Technology, Abuja between August 2018 and Sept...
This research appraises the possibility of using bricks as an alternative to sandcrete block towards solving the housing problem of the lower income group in Nigeria. The study adopted the survey method through interview and questionnaires. The simple random sampling approach was...
