• Shaping the rings of molecules
  

  Macrocycles are molecules made of large rings of atoms. Despite being relatively big and flexible, the molecules don't always stay "floppy" -- they can actually lock themselves into specific shapes and geometries. In manufacturing, controlling the three-dimensional shapes of macrocycles is critical. more

• Graphene forms under microscope's eye
  

  You don't need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns. The labs of R more

• Quantum microscope for inspection of magnetic materials at the nanoscale
  

  Qnami announced the closing of a CHF 2.6M (USD 2.6M) seed round led by Venture Capital fund Quantonation and further supported by investiere, ZKB Start-up Finance and the High-Tech Gründerfonds. The funds will support the market entry of Qnami’s first product, a quantum microscope for inspection of 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
