Gas metal arc welding (GMAW) wire arc additive manufacturing (WAAM) processes use inert shielding to protect the weld arc during material deposition, but do not protect the trailing bead, which can lead to weld issues varying from low finish quality to diminished material prop
ORNL has developed bacterial strains that can utilize a common plastic co-monomer as a feedstock. This will help enable modern, petroleum-derived plastics to be converted into value-added chemicals.
Due to a genes unique nucleotide sequences acquired through horizontal gene transfer, the gene has a transcriptional repressor activity and innate enzymatic role.
We have developed bacterial strains that can convert sustainable feedstocks and waste feedstocks into chemical precursors for next generation plastics.
ORNL has identified a panel of novel nylon hydrolases with varied substrate and product selectivity.
Genetic modification of microbes that are thermophiles—ones that grow at elevated temperatures—is extremely challenging. Tools developed for E. coli, a typical host for protein production, typically do not function at elevated temperatures.
