Pre-stressed concrete is an ideal material for beam bridge construction; the concrete withstands the forces of compression well and the steel rods imbedded within resist the forces of tension.

Traveling from one star to another is currently impossible to achieve within a human lifetime. But some projects are ...

The integrations needed to determine beam deflections require the enforcement of the appropriate displacement and rotation boundary conditions (BCs). It is important that we be able to recognize these ...

A team has gained new insights into lithium-sulphur pouch cells at the BAMline of BESSY II. A new picture emerges of processes that limit the performance and lifespan of this industrially relevant ...

Light's shadow: Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line ...
