VALENCE CHANGE ABILITY AND GEOMETRICAL OCCUPATION OF SUBSTITUTION... Chemical Engineering

Nanoparticles were then mixed with Vulcan carbon CX72 with a mass ratio of C:XFe2O4 = 40:60. The as-prepared C/XFe2O4 (XFe2O4 = 60 w%) material and polyvinylidene difluoride (PVDF) were mixed in a mass ratio of 90:10 and dispersed in N-methyl pyrrolidone (NMP). The resulting slurry was pasted onto n... Continue Reading

THE EFFECT OF SILVER IONS AND NANOPARTICLES ON BIOFILMS AND PLANK... Chemical Engineering

Nanotechnology is a rapidly growing industry concerned with the fabrication of materials and products at the nanoscale (1 – 100 nm). The increased surface area to volume ratio of nanomaterials relative to... Continue Reading

SOLAR THERMOCHEMICAL ENERGY STORAGE THROUGH CARBONATION CYCLES OF... Chemical Engineering

Concentrated solar power (CSP) generation combined with energy storage has the intrinsic advantage of dispatchability, which is the ability to provide energy upon demand, or alternatively, store energy when there is no demand. Despite this advantage, a transformational breakthrough is needed in the... Continue Reading

MULTISCALE EFFECTS OF INTERFACIAL POLYMER CONFINEMENT IN SILICA N... Chemical Engineering

For many natural and synthetic composite materials, enhancing or reinforcing the linear and nonlinear viscoelastic properties of polymer (elastomer) materials is accomplished by inclusion filler particles (e.g. carbon black, silica).1–4 Mechanical properties of elastomer systems can be substantial...

HETEROAGGREGATION BETWEEN CITRATE-STABILIZED GOLD NANOPARTICLES A... Chemical Engineering

Understanding the aggregation behavior of engineered nanomaterials (ENMs) in aqueous environments is essential to understanding their fate, transport, and toxicity. Because naturally occurring colloids will likely be present at much higher concentrations than ENMs in environmental systems, heteroag... Continue Reading

A COMPARATIVE STUDY OF CHEMICAL AND MICROWAVE SYNTHESIZED ACTIVAT... Chemical Engineering

Activated carbon, also widely known as activated charcoal or activated coal is a form of carbon which has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions (Mattson et al., 1971). The word active is sometimes used in... Continue Reading

COMPARATIVE ANALYSIS OF COAL FUEL OIL AND NATURAL GAS FOR CEMENT... Chemical Engineering

This study is a comparative analysis of the use of coal, fuel oil and natural gas for cement production noting their physical and chemical properties, cost and availability, impact on the environment and human health. Out of the seven cement manufacturing industries in Nigeria, three industries use... Continue Reading

ANALYSIS OF BUSH PEAR AND ITS OIL Chemical Engineering

The research project studies the analysis of pear and its oil. The mesocarp from edible African pear “DacryodesEdulis” were evaluated for their oil yield. The pulp from this pear were oven dried at 100oC-105oC to a moisture content level of 29%.The mesocarp was subjected to proximate analysis to det... Continue Reading

ASSESSMENT OF CARBON MONOXIDE CO LEVEL IN ENUGU METROPOLIS MONITO... Chemical Engineering

Air pollutions pollutant showed that the extent of spreading depends on the motor vehicle traffic population of the area. This pollution strongly generated through combustion of fossil fuels presents difficult environmental challenge to societies as it could degrade the environment and affect human... Continue Reading

DESIGN AND FABRICATION OF MAIZE CORN ON COB TRAY DRYER Chemical Engineering

This study was carried out to generate a design data, design and fabricate a maize corn-on-cob tray dryer used by maize farmers. Ripped maize corns with husks were bought from the market and preserved to retained its moisture content, dehusked and thereafter, dried to a given percentage moisture con... Continue Reading

EFFECT OF PARTICLE SIZE ON OIL YIELD USING SCENT BEAN SEED Chemical Engineering

This project was done to extract and characterize bean oil according to their particle sizes. The experiment was carried out using scent bean (i.e. ‘Ozaki’, ‘Ijilizi’or ‘Azamu’) as sample. The oils were extracted by solvent extraction /leaching extraction using n-hexane. Proximate analysis was carri... Continue Reading

EXTRACTION AND FORMULATION OF PERFUME FROM PLANT Chemical Engineering

The word perfume derives from the latin ―per fumum‖ meaning through smoke, is fragrant liquid that is sprayed or rubbed on the skin or clothes to give a pleasant smell. Extraction of perfume from various plants resources is of ancient origin. Infact the natives from different tropical regions of the... Continue Reading

EXTRACTION AND FORMULATION OF PERFUME FROM LEMONGRASS LEAVES Chemical Engineering

Perfume extraction refers to the extraction of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression or enfleurage. The extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.... Continue Reading

HEAD LOSES IN HORIZONTAL AND VERTICAL ORIFICEMETER A COMPARATIVE... Chemical Engineering

A comparative investigation was undertaken to determine the head loss coefficients for horizontally mounted and vertically mounted orifices using a Fluid mechanics and Heat transfer trainer developed in Nigeria. Experiments were carried out observing the procedure and the discharge of the flow of wa... Continue Reading

MODIFICATION OF SURFACE PHYSICAL AND CHEMICAL PROPERTIES OF ACTIV... Chemical Engineering

The purpose of this work was to study the effect of chemical surface properties of activated carbons for their use in water purification. To achieve this objective, activated carbon in both granular and powdered forms namely: as received and devolatilized carbons were prepared. Proximate analysis of... Continue Reading
