Niobium to the Rescue!
I suspect everyone reading a recent ASME article was told, at least once when they were young, not to put an electrical device or live cord into water. This led to a corollary that you should not connect electrical wires under water. For those who work with electrical equipment, all underwater, this can be a […]

Paper a Roof to Save Cooling Energy
Northeastern University researchers have developed a new “paper” that, when applied to roofs, can dramatically reduce cooling loads. The paper is made of hydroxyapatite materials spun into fibers and made into a paper. Its white color reflects the majority of the direct rays from the sun. In addition, heat from inside the structure is radiated […]
Sports Trend – The Venue over the Game?
Sports stadiums typically started off as purely static structures, falling mostly under civil engineering. They were interesting structures, but the game being played was clearly the center of attention. However, today we have stadiums that are anything but static. Moving roofs, moving fields, moving stands, a very visible world of mechanical engineers and civil engineers […]
