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 new mass production method based on printing technologies allows the manufacturing of decorative, organic solar panels. Design freedom improves the range of applications of the panels on the surfaces of interior and exterior building spaces.
A new method enables electroluminescence on large, curved surfaces in a cost-effective way: in this case, the light-emitting layer and all other components are produced by means of wet-chemical, printable methods.
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.
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.
Research probing the complex science behind the formation of dendrites that cause lithium-ion batteries to fail could bring safer, longer-lasting batteries capable of being charged within minutes instead of hours.
