Colloidal solutions of gallium arsenide quantum dots of the type used in lasers, TVs, solar cells, medical devices, and other electronics glow under UV light. These were grown using a groundbreaking ...

Tsukuba, Japan—The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to ...

Nature keeps a few secrets. While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable ...

Colloidal nanocrystals (CNs) are artificially grown inorganic particles stabilized by surfactants. Those smaller than 10 nm can transform their optical and electronic properties and exhibit a quantum ...

Quantum dots are composed of semiconducting materials like cadmium selenide (CdSe) or indium arsenide (InAs) and can be synthesized through various methods. For instance, colloidal synthesis and ...
