Development and quantification of biodiesel production from chicken feather meal as a cost-effective feedstock by using green technology.

Increased urbanization and increase in population has led to an increased demand for fuels. The result is the prices of fuels are reaching new heights every day. Using low-cost feedstocks such as rendered animal fats in biodiesel production will reduce biodiesel expenditures.

Synthesis, characterization and evaluation of antimicrobial efficacy and brine shrimp lethality assay of stem bark extract mediated ZnONPs.

is one of the most important medicinal plants and herein, we present the synthesis of zinc oxide nanoparticles using the bark extract of and evaluation of their antimicrobial efficacy. Stable ZnO nanoparticles were formed by treating 90 mL of 1 mM zinc nitrate aqueous solution with 10 mL of 10% bark extract. The formation of bark extract mediated zinc oxide nanoparticles was confirmed by UV-visible spectroscopic analysis and recorded the localized surface plasmon resonance (LSPR) at 430 nm.
