Scientists have created unique two-dimensional flakes with two distinct personalities: molybdenum diselenide on one side of a sharp divide with rhenium diselenide on the other. The materials show promise for optoelectronics.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences have grown simplified organs, known as organoids, with fully integrated sensors. These so-called cyborg organoids offer a rare glimpse into the early stages of organ development and could be used to test and monitor patient-specific drug treatments and for transplantations.

To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also need to be able to let light in (for solar cells) or out (for displays). Metal is opaque, so the current techniques use metal oxides, most often indium tin oxide, as the conductive contact. Because supplies of indium tin oxide are limited, Lawrence Livermore National Laboratory researchers have turned to ordered metal nanowire meshes that use more common elements and provide high transmissivity and high electrical connectivity.

A team of environmental scientists has, for the first time, used a dynamic, two-step process to completely degrade a common flame-retardant chemical, making it nontoxic.

Researchers have found that spraying a gel on the internal tissues of animals after cardiac surgery greatly reduces fibrous bands that form between internal organs and tissues. Such fibrous bands can cause serious, even fatal, complications. The gel, developed to deliver medications, was far more effective than materials currently on the market, the researchers said.

Laboratories use surfactants to separate things and fluorescent dyes to see things. Rice University chemists have combined the two to capture images of single nanotubes or cells as simply as possible.
