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.
