Understanding electron behavior and surface structure of triphenylene thin film molecules deposited on graphite substrates under light irradiation

Tin sulfide (SnS) solar cells have shown immense promise in the rush to develop more environmentally friendly thin-film solar cells. Yet for years SnS solar cells have struggled to achieve a high conversion efficiency. To overcome this, a SnS interface exhibiting large band bending was necessary, something a research group has recently achieved.

Research by Japanese scientists at Hiroshima University reveals a way to make ammonia from its constituent molecules of nitrogen and hydrogen at ambient pressure.

The remaining “bound water” on cotton surfaces cross-link single fibers of cotton, causing hardening after natural drying, according to a new study conducted by Kao Corporation and Hokkaido University. This provides new insight into unique water behaviors on material surfaces and helps us develop better cleaning technologies.
