Herein, an ultrasonication approach was used to anchor In2S3 quantum dots (QDs) onto oxygen-doped graphitic carbon nitride (O@g-C3N4), resulting in a novel heterojunction catalyst. Characterization techniques validated the successful incorporation of In2S3 into the O@g-C3N4 matrix, with transmission electron microscopy (TEM) indicating the existence of In2S3 QDs measuring 6.62 nm. The photocatalyst

There is a body of evidence that ultrafine particles (UFP, those with diameters ≤ 100 nm) might have significant impacts on health. Accordingly, identifying sources of UFP is essential to develop abatement policies. This study focuses on urban Europe, and aims at identifying sources and quantifying their contributions to particle number size distribution (PNSD) using receptor modelling (Positive Matrix

The country’s research progress means its cities might lead in all Nature Index subjects within a decade.

Provincial capitals such as Hefei are outscoring some established science cities in the Nature Index — here’s why.

European cities make their mark while the United States extends its lead.

Just passing time.

Although the United States maintains a steady lead, Chinese cities are on the rise.

African researchers piloted a slew of innovative, low-cost programmes for addressing the troubling shortage of mental-health professionals on the continent. Now the rest of the world is taking notice.

Although I find new ways to express myself as a student abroad, sometimes it can be isolating to avoid my mother tongue, writes Rahul Roy.

Climate change has driven hurricane wind speeds up by an average of nearly 30 kilometres per hour, an analysis of Atlantic storms shows.

Although Beijing has solidified its top spot in the standings, the country’s regional cities are ones to watch.

But Chinese cities are quickly rising, thanks to significant government investment and targeted legislation.

I’m not sure if a management role in science is for me. How do I decide?

The policy has boosted tech transfer and economic growth in some regions, but challenges remain around innovation in key technologies.

The country’s rising players outperform US cities in year-on-year growth.

Impressive year-on-year growth has seen smaller hubs climb the list — but eyes remain on Beijing.
