(
Elsevier
, 2020 , Article)
© 2020 Bacillus thuringiensis (Bt) is a Gram-positive soil bacterium that has been recognized as an effective bioinsecticide active against plant, animal and human pathogenic and disease vector insects. During its sporulation ...
Effective NiMn nanoparticles-functionalized carbon felt as an effective anode for direct urea fuel cells
(
MDPI AG
, 2018 , Article)
The internal resistances of fuel cells strongly affect the generated power. Basically, in the fuel cell, the anode can be prepared by deposition of a film from the functional electrocatalyst on a proper gas diffusion layer. ...
