We probably don’t need to tell this to the average Hackaday reader, but we’re living in a largely disposable society. Far too many things are built as cheaply as possible, either because manufacturers ...

Photochemical etching is a machining technique that leverages the principles behind photography to shape a piece of sheet metal and turn it into a finished product or component. The modern form of ...

Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation ...

Photovoltaic efficiency has come a long way over the decades, but there’s always room for improvement. A new study analyses how to make solar thermoelectric generators, or STEGs, more efficient by ...

Researchers have developed a laser treatment technique able to transform metal surfaces and allow them to instantly kill bacteria on contact. Scientists at Purdue University announced on Thursday that ...

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar ...
