Abstract
The study examined energy levels of boron (B) doped crystalline Si (c-Si) with different
boron dopant concentrations and temperatures. In this work, energy levels
ofboron doped
c-Si were studied
using ...
Tanning efJluent from leather processing industries is very complex and leads to
environmental pollution
if discharged untreated, especially due to its high organic
loading and chromium content.
In this study five ...

Ethiopian population uses biomass as a primary energy sources. More than 50% of this energy accounts for injera baking. Injera baking devices were prepared by combination of clay soil, copper metal powder and water as a ...
Dimers are low molar mass LC molecules consists of two identical rigid rod like structural
molecule called mesogen jointed by highly flexible alkaline core spacer that provide the
necessary mobility with in the LC phase. ...
Diblock star copolymers (DBSCP) are polymers of the two chemically distinct monomer units
covalently bonded to form macromolecule of Diblock star copolymer unit. These types of polymer
can be synthesized in three mechanisms ...
In this study, green synthesis, characterization and antibacterial activity of zinc oxide nanoparticles was studied. The zinc oxide nanoparticles were successfully synthesized via a fast, convenient, cost-effective, and ...
Star shaped polymers are a relatively new class of super-molecules. Star shaped polymers are complex branched polymer which consists of at least three arms and one central core. Star shaped polymers have unique topological ...
