Simulating failure to find the strength in composites

Fiber-reinforced composites are widely used in aerospace and other high-tech industries. Understanding how their microstructure and the strength of the fiber-matrix interfaces affect their failure properties can lead to manufacturing ...

High color purity 3-D printing

Selective powder sintering for 3-D printing has recently become an increasingly affordable solution for manufacturing made-to-order elements of almost any shape or geometry. This technique involves heating a bed of powder ...

Researchers model potential of toxic algae photoreceptors

Blue-green algae is causing havoc in Midwestern lakes saturated with agricultural run-off, but researchers in a northwest Ohio lab are using supercomputers to study a closely related strain of the toxic cyanobacteria to harness ...

Manufacture of light-activated proteins

A new strategy for designing light-sensitive proteins has been developed by researchers at Ruhr-Universität Bochum (RUB). Such proteins, also known as optogenetic tools, can be switched on and off through light impulses, ...

Nation's fight against cyber intruders goes local

The next frontier in the fight to keep crucial electronic networks safe from harm will play out as close to home as Town Hall and require more involvement from private industry, which controls 85 percent of the infrastructure, ...

Cost savings from add-on pricing may result in profit loss
