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...
