Empa researchers are working on electronics that come out of printers. This makes it possible to produce the circuits on all sorts of substrates, such as paper or plastic film – but there are still some hurdles to overcome. Imagine being able to easily print electronics on any surface. Today, this i more
The ocean floor and the ground beneath our feet are riddled with tiny nanowires -- 1/100,000th the width of a human hair -- created by billions of bacteria that can generate electric currents from organic waste. In new research published Aug. 17 in the journal Nature Chemical Biology, Yale researche more
Oliver Hofmann and his research group at the Institute of Solid State Physics at TU Graz are working on the optimization of modern electronics. A key role in their research is played by interface properties of hybrid materials consisting of organic and inorganic components, which are used, for examp more
Video shows layered, self-assembled graphene oxide sheets with synthetic proteins patterned on squid ring teeth made into an actuator with substantial curvature. The second segment shows the same device using graphene oxide only. There is no movement.Credit: Melik Demirel,/Penn State. more
Regular readers will spot that today’s post is a bit of a twist on an old post from the site’s archives, which looked at the elements present in a smartphone and the roles that they play. In this updated version, I wanted to highlight which elements in your smartphone will actually get recycled at t more
Hydrogel films have promising applications in medical dressings, flexible electronics, etc. However, it is challenging to fabricate ultrathin hydrogel films with high toughness and controllable thickness. Here, we report a facile approach to prepare tough physical hydrogel films by spin-coating of a more
By breaking through the energy density limits step-by-step, the use of lithium cobalt oxide-based Li-ion batteries (LCO-based LIBs) has led to the unprecedented success of consumer electronics over the past 27 years. Recently, strong demands for the quick renewal of the properties of electronic prod more
The rare earth elements (REEs) play critical roles in modern consumer electronics and clean technologies, but unpredictable supply and environmentally unsustainable extraction practices have spurred efforts to develop green methods of recovering the metals from waste streams. In this regard, we have more
completed an apprenticeship as a radio and TV electrician before studying electronics, instrumentation and control technology at Neutechnikum Buchs (Switzerland), graduating as the year’s best student in 1990. He completed both his master’s degree and his later doctorate (1996) at Northwestern Unive more
