Researchers develop high-strength nanotwinned aluminum alloy

Green Car Congress

Researchers have demonstrated how to create a super-strong aluminum alloy (nanotwinned Al-Fe) that rivals the strength of stainless steel, an advance with potential applications in the automotive and aerospace industries. Meanwhile, “twin boundaries” consisting of two layers of stacking faults can form. Sichuang Xue, Zhe Fan, Olawale B.

UNL-led team greatly increases hydrogen production by T maritima; breaking the theoretical limit

Green Car Congress

Researchers at the University of Nebraska-Lincoln (UNL), with colleagues from North Carolina State University and the University of Connecticut, have engineered the hyperthermophilic anaerobe Thermotoga maritima to produce 46% more hydrogen per cell than the wild type. The team’s highest reported yield—5.7 doi: 10.1128/AEM.00998-18.
