source:CosmosNewly discovered semiconductor nanocrystals could be used to develop highly efficient light-emitting devices and lasers.The nanocrystals are described in a new paper published in the American Chemical Society journal ACS Nano.Nanocrystals are often used in devices such as lasers or light-emitting diodes (LEDs). These are mainstays of modern technology, so finding more efficient ways of producing these semiconductor elements would mark a major advance in technology development.One challenge in nanocrystals is the so-called “dark” exciton.Excitons are essential in semiconductors. Th...

Rare earth carboxylate compounds on the barrier properties and active corrosion inhibition of epoxy coatings on mild steelsource:eropean coatingsResearchers found that the addition of lanthanum 4-hydroxycinnamic acid (La(4-OHcin)3) and yttrium 3-(4-methylbenzoyl)propionate (Y(mbp)3) to bisphenol-based epoxy resin coatings significantly improves corrosion resistance and delays electrolytic penetration.In a current research, two rare earth carboxylate compounds, lanthanum 4-hydroxycinnamate (La(4-OHcin)3) and yttrium 3-(4-methylbenzoyl)propanoate (Y(mbp)3), were incorporated into bisphenol-based...

source:Technology ReviewLeaving aside meteorites that strike Earth’s surface and spacecraft that get flung out of its orbit, the quantity of materials available on this planet isn’t really changing all that much.That simple fact of our finite resources becomes clearer and more daunting as the pace of technological change advances and our society requires an ever wider array of material inputs to sustain it. So for nearly as long as we’ve systematically extracted these substances, we’ve been trying to predict how long they will be able to meet our demand. How much can we pump from a well, or wr...
