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.

A spoonful of sugar in silver nanoparticles to regulate their toxicity

The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the U.S., can be harmful to health. Scientists have now confirmed that silver nanoparticles are significantly toxic when they penetrate cells, although the number of toxic radicals they generate can vary by coating them with carbohydrates.

Watching protein crystal nucleation in real time

A major hurdle in structural biology and pharmacology is growing crystals to determine the structure of the biomolecules and pharmaceuticals under study. Researchers have now observed a key step in the nucleation and growth of some protein crystals.
