• A new method for the functionalization of graphene
  

  An international research team involving Professor Federico Rosei of the Institut national de la recherche scientifique (INRS) has demonstrated a novel process to modify the structure and properties of graphene, a one atom thick carbon. This chemical reaction, known as photocycloaddition, modifies t more

• This flexible and rechargeable battery is 10 times more powerful than state of the art
  

  A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, thi more

• Turning streetwear into solar power plants
  

  Empa researchers succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly where it is needed, i.e. in the use of everyday electronics. Our hunger for energy is insatiabl 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
