• '4-D printing' a new dimension for additive manufacturing

  23-08-2016 20:18
  Researchers have demonstrated the 3-D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity, an approach also known as '4-D printing.' The micro-architected structures, including boxes, conductive devices, and a stent, were fabricated from a conductive, environmentally responsive 'smart' ink.

• Silicon nanoparticles trained to juggle light

  23-08-2016 18:54
  Silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity. They could be integrated into microchips that would enable ultrafast all-optical signal processing in optical communication lines and the next generation optical computers.

• Analog DNA circuit does math in a test tube

  23-08-2016 18:53
  Researchers have created strands of synthetic DNA that, when mixed together in a test tube in the right concentrations, form an analog circuit that can add, subtract and multiply as the molecules form and break bonds. While most DNA circuits are digital, their device performs calculations in an analog fashion by measuring the varying concentrations of specific DNA molecules directly, without requiring special circuitry to convert them to zeroes and ones first.

• Stretchy supercapacitors power wearable electronics

  23-08-2016 14:32
  A future of soft robots or smart T-shirts may depend on the development of stretchy power sources. But traditional batteries are thick and rigid -- not ideal properties for materials that would be used in tiny malleable devices. In a step toward wearable electronics, a team of researchers has produced a stretchy micro-supercapacitor using ribbons of graphene.
