Graphene specimen support technique for low voltage STEM imaging

Developing new scientific devices pushing the limits of what we can observe and measure does not occur overnight. There are typically baby steps involved, small and continuous improvements to counter the numerous technical ...

Revealing polymeric fluids behavior at the microscopic scale

An important concept in future healthcare is the development of devices called "lab on a chip." These "chips," not related to the electronic ones found in computers, are small devices in which biological fluids – blood ...

Parallel computation provides deeper insight into brain function

Unlike experimental neuroscientists who deal with real-life neurons, computational neuroscientists use model simulations to investigate how the brain functions. While many computational neuroscientists use simplified mathematical ...

Iron nanocubes may be key in the future of NO2 sensing

While nanoparticles sound like a recent discovery, these tiny structures have been used for centuries. The famous Lycurgus cup, made by 4th century Roman artisans, features dichroic glass, with gold and silver nanoparticles ...

To buckle or not to buckle

Magnetic balls provide exciting avenues for exploring many fundamental phenomena in physics. They can be assembled by hand into chains and more complex structures and used to model the properties of unstretchable materials ...
