Synthetic method dependent physico- chemical properties and electrochemical performance of Ni doped Synthetic method dependent physico-chemical properties and electrochemical performance of N

Nickel doped zinc oxide (Ni/ZnO) nanostructures have the potential to improve the performance of electrochemical capacitors. This study investigates the preparation of Ni/ZnO nanomaterials by facile co-precipitation (CPM) and hydrothermal (HTM) methods. The effect of the synthesis methods on the optical, structural, chemical and morphological properties on ZnO products is investigated using ultra violet (UV)-visible spectroscopy, X-ray diffraction (XRD), field emission scanning electron micro...

Catalytic conversion of polyethylene to liquid fuel and solid wax using the (CaOH2)

ABSTRACTThe objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cata...

Production of Biopesticide from Need Seed

Abstract Due to the toxic effects of chemical pesticide and other agro chemicals on human beings and livestock, residual toxicity, environmental problems, pest out-breaks and drastic effects on beneficial insects the use chemical pesticide and other agro chemicals are getting reduced /being banned globally. But Biopesticides that are extracted, for example, from neem seed can tackle these problems to make it more eco-friendly, economically viable and socially acceptable for the ...

Air pollution

The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood  fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...

DETERMINATION OF REMOVAL EFFICIENCY OF METHYLENE BLUE FROM AQUEOUS SOLUTION USING CHEMICALLY ACTIVATED CARBON PRODUCED FROM MANGO SHELL

ABSTRACTThe presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.03...

OPTIMIZATION OF CONDITIONS FOR THE PRODUCTION OF ACTIVATED CARBON FROM MANGO KERNEL SHELL USING BARIUM CHLORIDE AS THE ACTIVATING AGENT

ABSTRACTThis study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167 ...

INVESTIGATION INTO THE EFFECTS OF TEMPERATURE ON ITAKPE IRON CONCENTRATE MAGNETO VISCOUS FLUIDS

ABSTRACTThis research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid.It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian vis...

Extraction and Phytochemical Analysis of Oil from Neem and Morning Oleifera Seeds and Leaves

ABSTRACTPhytochemicals are chemical compounds produced by plants, generally to help them thrive or thwart competitors, predators, or pathogens. These chemicals are produced by plants through primary or secondary metabolism (Breslin A,2017) . These work was done to determining the presence of phytochemicals such as Tannins, Saponin, Alkaloids, Anthraquinone, Phlobatannins, Flavonoids and  Cardiac Glycosides (e.g Steroidal Ring or Terpenoids and cardenolide) from oil extracted from mo...

Effect of Surface Area on the Extraction of Silica from Rice Husk and Wheat Husk

Silicon dioxide , also known as silica (from the latin silex), is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and invarious   living   organisms.   In   many   parts   of   the   world,   silica   is   the   major constituent of sand. Silica is one of the most complex and most abundant families of materials existing as a compou...

COMPARATIVE STUDY OF THE DIFFERENT METHODS USED IN RE-REFINING USED LUBRICATING OIL

Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, removing contaminants from the engine, act as a cleaning agent, and act as an anti corrosion and cooling agent.Accordingly, this research effort focuses on comparative study of re-refined engine oils by acid treatment, acid/clay treatment, so...

Research Paper on Hand Sanitizer

AbstractThe 15th of October has been decreed a day to focus on germs specifically. It’s the germs on our hand that are in the firing line .The world health organization estimates that 3.5 million children die from diarrhea and lower respiratory tract infections each year. That’s why global hand washing day was decreed. Sanitation of hand has a great effect on the wellbeing of life in general. By maintaining ones sanitation different kind of diseases which are caused by contact can ...

Conversion of Waste Plastics to Fuel Oil

AbstractWaste plastic disposal and excessive use of fossil fuels have caused environmentconcerns in the world. Both plastics and petroleum derived fuels are hydrocarbons thatcontain the elements of carbon and hydrogen. The difference between them is that plasticmolecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, itis possible to convert waste plastic into fuels.The main objectives of this study were to understand and optimize the processes of plasticpyr...
