I said, 'Are you sure you washed away all the reducing agent
?' We went on and on about what is causing it until we found out that it's actually being caused by water droplets themselves, even when they're not externally charged.
Blanchard, Formation of gold nanoparticles using amine reducing agents
. Lang., 22 , 5882, (2006).
The components involved in the biological synthesis of nanoparticles include a solvent medium for synthesis, an environmentally friendly reducing agent
, and a nontoxic stabilizing agent .
Silver nanoparticles were synthesized using CMC as stabilizer and reducing agent
. The reactions were carried out at 0[degrees]C; this low temperature was used because particle growth is slower at lower temperatures; it favors stabilization during nucleation and promotes obtaining of more stable nanoclusters; furthermore, at low temperatures, CMC adsorption on the nanoparticles is larger, given more stability [20, 21].
Hydrogen tetrachloroaurate was reduced using 1,4,7,10,13,16,21,24-octazabicyclo[8.8.8] hexacosane (azacryptand) as stabalizing and reducing agent
to synthesize spherical nanoparticles with an average diameter of 20.9 3.3 nm .
The team then replaced the cysteine in the experiment with another reducing agent
: Vitamin C.
Current technology includes heating crude oil and injecting drag reducing agent
(DRA) chemicals to reduce oil viscosity.
It is based on N-heterocyclic carbene catalyst and a silane as the reducing agent
The pro cess uses chemicals that are environmentally friendly, such as ascorbic acid (vitamin C) as a reducing agent
, and requires less catalyst.
Injection for Removal of Residual Disinfecting Agent
Typically, SCR systems use a nitrogen-containing reducing agent
(usually ammonia or urea) that is injected into the engine's exhaust upstream of the catalyst.
The addition of a reducing agent
sets up an equilibrium between [Cu.sup.I] and [Cu.sup.II] and maintains the balance throughout the reaction."
