Ultra-thin Semiconductor Opens Door for Product Innovation
Scientists have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets three atoms thick. The University of Washington researchers demonstrated that two of these single-layer semiconductor materials can be connected in an atomically
ASTM B831: Test Method for Shear Testing of Thin Aluminum Alloy Products
ASTM B831 is amended to include a new appendix that was created to describe a novel shear test sample geometry and incorporation of digital image correlation for shear strain measurement.
ASTM WK40615: Practice for Mixing and Comparing Performance of Concrete Materials Using Mini-Mix Mortar Mixtures
Concrete technologists need to have a well-defined, useful and efficient means to detect and possibly address concrete material incompatibility issues. This need will be addressed in a proposed new ASTM International standard, ASTM WK40615, Practice for Mixing and Comparing Performance of Concrete
