Glass bottles tossed in the trash are finding new life thanks to a collaboration between the Department of Energy's Oak Ridge National Laboratory (ORNL) and Vitriform3D, an advanced manufacturing company.

Researchers developed an electrochemical process that converts limestone and silica into calcium silicate hydrate at 60 °C and 1 bar, enabling belite-rich cement clinker to form at 650 °C rather than the conventional 1200 °C. Using waste cement as the calcium feedstock, the modeled process could reduce production-stage CO2 emissions to 20 kg per ton of cement, a 98% reduction co...

Secondary Ion Mass Spectrometry is a surface analysis technique known for high sensitivity and excellent depth resolution in the analysis of solid materials.

Triply-twinned body-centred cubic lattices shift strut-scale deformation from bending to stretching, producing major gains in stiffness and strength across polymer and titanium metamaterials. High-resolution synchrotron XCT revealed that lattice architecture governs global shear-band failure, while additive manufacturing defects mainly determine where local fractures begin.

The Department of Energy's Pacific Northwest National Laboratory has established the Enhanced Visibility and Event Response capability to help grid operators adapt to a rapidly evolving electricity system and thwart potential adversarial cyber and physical attacks on the grid.
