When designing materials and structures at the nanoscale, it is important to be able to characterize and measure them. Getting tools to measure on these very small length scales can be challenging as ...

Scientists at Penn State have discovered an effective and precise way to make ultraminiature metal wires in very close proximity to each other. Their work—important because nanoscale construction ...

We can add yet another way to measure the universe’s expansion onto the pile of controversy that could perhaps be the most exciting story in cosmology today. The universe is expanding. Measurements of ...

The workhorse of current nanofabrication processes, electron beam lithography (EBL), has good resolution but it is difficult to precisely control the pattern size at the sub-20 nm scale due to the ...

The Mathematics Teacher (MT), an official journal of the National Council of Teachers of Mathematics, is devoted to improving mathematics instruction from grade 8-14 and supporting teacher education ...
