A silkworm fluorescing under green lightHuan-Ming XiongSilkworms that eat nanometre-sized particles called quantum dots produce fluorescent silk.Researchers have previously used gene editing to make fluorescent silkworms, but these methods can be cos...
AdvertisementPhotovoltaic cells remain woefully inefficient at converting sunlight into electricity. Although layered cells composed of various elements can convert more than 40 percent of (lens-concentrated) sunlight into electricity, more simple se...
AdvertisementMost photovoltaic solar cells have an inherent efficiency cap, limiting how much useful energy they can extract from the sun. But scientists are finding ways around this obstacle with new research that could make solar energy more effici...
QUANTUM dots – tiny pieces of semiconductor – have already proven their worth in medical imaging thanks to their bright rainbow colours. Now it turns out they’re also extremely good at making deliveries inside living cells.This is great news...
PEPPERING solar cells with quantum dots could be the next step towards cheaper solar power, allowing basic devices to generate more electricity than ever before. The new technique borrows a trick from photosynthesis to convert light into electricity....
AdvertisementSemiconductor crystals known as quantum dots have long held the promise of improving solar cells, lasers and lighting fixtures, but the reality is that integrating these fluorescent nanoparticles into existing technologies has proved dif...
The blind dot-maker(Image: Jef Meul/Minden Pictures/FLPA)IS IT time chemists abandoned their white coats in favour of trowels? Ordinary earthworms are proving to be a sophisticated chemistry lab they can put together substances with unusual light-emi...
(Images Edward A. Sykes & Qin Dai)They may look like something captured by the Hubble telescope, but these mice are revealing more about their inner space than what’s in outer space. The fluorescent speckles, spots and clouds marking their...
