• A battery with a twist
  

  Markus Niederberger’s team of researchers at ETH has used stretchable materials to develop a battery that can be bent, stretched and twisted. For applications in bendable electronic devices, this is precisely the kind of battery they need. Today’s electronics industry is increasingly focusing on com more

• Silicon as a semiconductor: silicon carbide would be much more efficient
  

  In power electronics, semiconductors are based on the element silicon – but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon i more

• Nylon as a building block for transparent electronic devices?
  

  Scientists at the Max Planck Institute for Polymer Research (MPI-P) led by Dr. Kamal Asadi have solved a four decade long challenge of producing very thin nylon films that can be used for instance in electronic memory components. The thin nylon films are several 100 times thinner than human hair and more

The Recycling Rates of Smartphone Metals

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

• Spin-coating-assisted fabrication of ultrathin physical hydrogel films with high toughness and fast response

  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

• Reviving lithium cobalt oxide-based lithium secondary batteries-toward a higher energy density

  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

• Repurposing bacterial extracellular matrix for selective and differential abstraction of rare earth elements

  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
