Nanotechnology deals with the production and usage of material with nanoscale dimensions (1-
100 nm). The nanoscale dimension provides nanoparticles with a large surface area to volume
ratio and thus very specific ...
In ancient times people used plants for treatment of different types of disease. Phytochemicals are
compounds that occur naturally in plants. Corchorus olitorius (family; Tiliaceae) locally known as
“Kudra” is used as ...
Due to its benefits over physical and chemical techniques of synthesis, researchers have recently
shown a great deal of interest in green synthesis of silver nanoparticles for a variety of
applications. As a reducing ...
In this study, a CuSO4.5H2O solution was reduced with mango extract at the optimal pH of 11 to
create copper oxide (CuO) nanoparticles in a quick, simple, and ecologically friendly manner.
CuO nanoparticle formation ...
Water pollution by methylene blue dye has become a reason for environmental pollution and has
been hostile to the aquatic ecosystem and this wastewater needs treatment. Nano sized, bismuth

Recently, many types of research in clay-based nanocomposites have been accomplished to
eliminate pollutants from water sources. Nanocomposite materials have advanced properties
useful for contaminate removal such as ...
Chromium (VI) emissions from industry have the potential to contaminate the environment
and accumulate in particular parts of the human body, posing a danger to life. In this study
volcanic ash (VA) and activated carbon ...
The present study used a plant mediated green synthesis of iron oxide nanoparticles (Fe3O4NPs)
through the chemical reduction of 10 ml of 0.005M FeCl3.6H2O solution and 1ml of 8 g palm
seed extract as reducing as well ...
All life depends on water being the main source is river waters, but give less attention to river
water quality, especially in developing countries like Ethiopia. This study was conducted to
assess the impact of ...
A new Manganese (II) complexes with tartaric acid (C4H6O6) and 2,2’-bpy ligands were
synthesized and characterized using various Physico-chemical (molar conductance, solubility
test, and melting point gravimetric ...
Cabbage is very important vegetable crop in Ethiopia and cabbage aphid is also one of the key
insect pests of cabbage which causes severe yield losses of the crop. The present study was
designed to assess farmers pest ...
Birds are one component of biodiversity and Ethiopia contains a high level of bird diversify.
Study on diversity, relative abundance, and habitat association of birds in Durja community
protected area, Awi Zone, Ethiopia, ...
This study investigates the determination of gold nanoparticle sizes using UV-Vis spectroscopy, a
powerful technique for analyzing the optical properties of nanomaterial. Gold nanoparticles exhibit
unique optical ...
Many diluted magnetic semiconductor oxide systems exhibit interesting room temperature
ferromagnetism, which has open the way for spintronics devices .Transition metal doped ZnO
