Protection against electromagnetic interference

Posted on by Haptic

Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight. Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components Read more about Protection against electromagnetic interference[…]

A new nanofiber material could protect soldiers, firefighters, astronauts and more

Posted on by Haptic

Since World War I, the vast majority of American combat casualties has come not from gunshot wounds but from explosions. Today, most soldiers wear a heavy, bullet-proof vest to protect their torso but much of their body remains exposed to the indiscriminate aim of explosive fragments and shrapnel. Designing equipment to protect extremities against the Read more about A new nanofiber material could protect soldiers, firefighters, astronauts and more[…]

A novel nanofiber filter demonstrates better performance in terms of breathability and filtration efficiency

Posted on by Haptic

The Department of Mechanical Engineering of The Hong Kong Polytechnic University (PolyU) has recently developed an electrostatically charged nanofiber filter with multiple separator layers, which can capture pollutant particles that are below 100 nm in diameter (covering the most common airborne nano-particles and viruses). The novel nanofiber filter demonstrates better performance in terms of breathability, Read more about A novel nanofiber filter demonstrates better performance in terms of breathability and filtration efficiency[…]
