The University of Konstanz and Chinese panel maker Longi have assessed the impact of gettering on LeTID in industrial ...

However, low grade silica sand, with a lower percentage of silicon dioxide and higher impurities, has traditionally been overlooked. In this article, we delve into the dynamics of the low grade ...

One significant area of research is the development of hyperdoped silicon, which involves introducing impurities into silicon at concentrations that exceed their equilibrium solubility.

Like silica fibres, chalcogenide fibres can be ... Varying levels of trace impurities, even at levels of a few parts per million, can alter the spectroscopic behaviour of a chalcogenide glass.

The calcium oxide then reacts with silica (sand) impurities in the haematite, to produce slag – which is calcium silicate.

The calcium oxide then reacts with silica (sand) impurities in the haematite, to produce slag – which is calcium silicate. This is separated from the iron and used to make road surfaces.
