• Alternative material investigated for superconducting radio-frequency cavity resonators
  

  In modern synchrotron sources and free-electron lasers, superconducting radio-frequency cavity resonators are able to supply electron bunches with extremely high energy. These resonators are currently constructed of pure niobium. Now an international collaboration has investigated the potential adva more

• Terahertz flashes uncover state of matter hidden by superconductivity
  

  Using the physics equivalent of the strobe photography that captures every twitch of a cheetah in full sprint, researchers have used ultrafast spectroscopy to visualize electrons interacting as a hidden state of matter in a superconductive alloy. It takes intense, single-cycle pulses of photons - fl more

• Superconducting synapse may be missing piece for 'artificial brains'
  

  Researchers at the National Institute of Standards and Technology (NIST) have built a superconducting switch that "learns" like a biological system and could connect processors and store memories in future computers operating like the human brain. The NIST switch is called a synapse, like its biolog more

Developing Advanced Lithium Ion Batteries

Today’s graphic takes a look at the research of Kent Griffith (@kentjgriffith), a PhD student from the University of Cambridge who’s currently looking into developing advanced lithium ion batteries to power our phones, laptops, and more. more

Transition Metals

This graphic looks at some general properties of the transition metals – I had a little less space to work with than with the previous graphics, on account of the large number of elements that the transition metals encompass, but hopefully what’s included is still of use. more

• Density functional theory investigation of negative differential resistance and efficient spin filtering in niobium-doped armchair graphene nanoribbons

  Using density functional theory calculations in combination with a non-equilibrium Green's function method, we explore the transport properties of a niobium-doped (∼3.57%) armchair graphene nanoribbon of dimer length 7 in a two-terminal device configuration. The band structure of the supercell with more
