Lethal spider’s web sheds light on material strength / La ragnatela del ragno mortale fa luce sulla resistenza del materiale. Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Joseph Cotellessa (Credit: Oxford University) A transatlantic team of researchers has discovered the secret behind the immense strength of the brown recluse spider’s silk. Known as one of the world’s most venomous arachnids, the brown recluse’s silk is also the strongest found anywhere in the spider kingdom. Now, scientists from Oxford University’s Department of Zoology and the Applied Science Department at Virginia’s College of William & Mary have revealed the source of the material’s exceptional toughness. Published in the journal Material Horizons , the research describes how the spider uses a micro-looping technique to reinforce its thread. This is facilitated by the recluse producing thin, flat silk that resembles a ribbon, rather than the round silk produced by other

Doped graphene foam shows super strength / schiuma di grafene drogato mostra una super forza Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Joseph Cotellessa (Credit: Tour Group/Rice University) Researchers at Rice University have developed a graphene foam reinforced with carbon nanotubes that can support up to 3,000 times its weight without deforming. Known as ‘rebar graphene’, the substance is described in the American Chemical Society journal  ACS Applied Materials and Interfaces . As well as exhibiting extreme mechanical strength, it was also successfully tested as a highly porous, conductive electrode in lithium ion capacitors. Rice chemist James Tour and his team had previously used carbon nanotubes to reinforce two dimensional graphene, and using the same process for three dimensional materials was a logical step. “We developed graphene foam, but it wasn’t tough enough for the kind of applications we had in mind, so using carbon nanotubes

Dubai to launch self-flying taxis this summer / Dubai sta per lanciare i taxi auto-volanti per questa estate. Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Joseph Cotellessa Driverless passenger drones could take to the skies above Dubai as soon as July 2017 according to the city’s transport chief. The plans were unveiled by Mattar Al Tayar, Chairman of Dubai’s Road & Transport Authority during a speech at the UAE’s annual World Government Summit. Al Tayer revealed that the city plans to use an autonomous aerial vehicle (AAV) produced by Chinese drone specialist Ehang. “RTA will spare no effort to launch the AAV in July 2017,” he said. Originally unveiled at the 2016 CES show in Las Vegas, the Ehang 184 is claimed to be the first vehicle of its kind to offer autonomous human flight over short-to-medium distances. Able to fly at altitudes of upto 500 metres and stay aloft for around 30 minutes, the fully unpiloted eight rotor airc
