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 ...

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 ...

Changing the ruler’s 0 origin means changing the position where the starting point (0) for measurement on the ruler is. The default zero position of the ruler is usually at the left edge of 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 ...
