Not exact matches

Researchers at UC Santa Cruz attacked this problem by focusing on perovskite nanocrystals, in which the instability problems are magnified by the large surface area of the particles relative to their volume.

Atoms on the surface are vulnerable to reactions that can degrade the material, so molecules that bind to the surface — called surface ligands or capping ligands — are used both to stabilize perovskite nanocrystals and to control their properties.

The material was synthesized by exploiting the structural evolution of platinum - nickel (Pt - Ni) bimetallic nanocrystals into cage - like structures with a self - assembled Pt skin structure on the interior and exterior surfaces.

The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Researchers from North Carolina State University have found that the transfer of triplet excitons from nanomaterials to molecules also creates a feedback mechanism that returns some energy to the nanocrystal, causing it to photoluminesce on long time scales.

Empa researchers have succeeded in developing an environmentally friendly ink for 3D printing based on cellulose nanocrystals.

«The direct growth of anchored MoSoy nanocrystals on graphene sheets may enhance the formation of strongly coupled hybrid materials with intimate, seamless electron transfer pathways, thus accelerating the electron transfer rate for the chemical desorption of hydrogen from the catalyst, further reducing the energy required for the reaction to take place,» Sasaki said.

Researchers at CNRS, CEA and the Université Grenoble Alpes propose an efficient alternative using semi-conductor nanocrystals (also called quantum dots) based on cheaper and less toxic elements, such as copper, indium and sulfur.
