Copper surfaces kill microbes that come into contact with them in a matter of hours. A new technique makes the familiar metal even deadlier—by zapping it with lasers. Bacteria “are becoming more ...

WEST LAFAYETTE, Ind. -- Bacterial pathogens can live on surfaces for days. What if frequently touched surfaces such as doorknobs could instantly kill them off? Purdue University engineers have created ...

Researchers from Purdue University have created a new laser treatment method that has the potential to turn any metal surfaces into a rapid bacteria killer by giving the surface a different texture.

Metal surfaces require careful observation, and this drawing tutorial focuses on how to accurately render stainless steel ...

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 ...

Surface grinding rmetal parts requires skill, and it’s time-consuming too because it involves multiple steps to give individual pieces an optimal finish. Metal products need proper finishing ...

Researchers at the US company Ion Optics have developed surface texturing processes that alter the emissivity of infrared sources, allowing them to be tuned for spectroscopic applications. This will ...

Efforts for a better understanding of the surface structures on the atomic scale have been continually paid for from then on. Au (111) surface, the most stable gold surface, has a periodic herringbone ...

Inspired by the naturally antimicrobial textures of cicada wings and shark skin, micro- and nanoscale textures at the scale of bacterial cells make it difficult for bacteria to attach. They also ...

These issues often stem from material limitations, including poor ion transport, unstable electrode interfaces, and dendrite formation in metal-based anodes. Overcoming these barriers requires ...
