Is glass a true solid?

Does glass ever stop flowing? Researchers have combined computer simulation and information theory, originally invented for telephone communication and cryptography, to answer this puzzling question.

Size matters: The importance of building small things

Strong materials, such as concrete, are usually heavy, and lightweight materials, such as rubber (for latex gloves) and paper, are usually weak and susceptible to tearing and damage. Julia R. Greer, professor of materials science and mechanics at Caltech is helping to break that linkage.

Gold 'nano-drills'

Spherical gold particles are able to 'drill' a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example.

A simple route to prepare stable liquid marbles

The aim of new research on the development of 'liquid marbles', also known as dry water, is to better understand the behaviour of this compound, in order to make advances in the use of cheaper materials, such as polystyrene.

Graphene-boron nitride heterostructures propagate light at the nanoscale

A new study exploits near-field microscopy to image propagating plasmons in high-quality graphene encapsulated between two films of hexagonal ?boron nitride. It finds unprecedentedly low plasmon damping combined with strong field confinement and confirms the high uniformity of this plasmonic medium.

Better metal contact improves two-dimensional transistor performance

Researchers found that silver provides a much better electrical contact to MoS2 than the widely used titanium, with the silver-contact devices having 60 times higher current when the device is in the 'on' state. These results are another step towards the advanced manufacture of high-value products based on 2D materials.
