The current nanofabrication techniques including electron beam lithography provide fabrication resolution in the nanometre range. The major limitation of these techniques is their incapability of ...

DEAR TIM: I’m getting ready to build a large room addition that needs a beam to support the floor joists. I’ve been told that a wood beam will work, but I’ve always seen steel I-beams in other houses.

Engineers' specific questions and concerns regarding the performance of the anchorage of the steel sections to the core walls prompted the most recent tests. The next round will investigate reducing ...

The photonic based technology boom of the late 1990s was driven by the need to replace expensive, lag-prone and limited satellite telecom links. These links were based on high frequency radio waves ...

A team has developed a 'deep learning-based ultrasound hologram generation framework' technology that can freely configure the form of focused ultrasound in real time based on holograms. It is ...

Q. I'm getting ready to build a large room addition that needs a beam to support the floor joists. I've been told that a wood beam will work, but I've always seen steel I-beams in other houses. Is it ...
