Colorful church windows, beads on a necklace and many of our favorite plastics share something in common -- they all belong to a state of matter known as glasses. School children learn the difference between liquids and gases, but centuries of scholarship have failed to produce consensus about how to categorize glass.
New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
Scientists have discovered inexpensive materials that can convert natural gas into useful chemicals under mild conditions, a new study in the 14 March issue of the journal Science reports. This approach may eventually compete with technologies for generating the same chemicals from petroleum, a fossil fuel that emits a lot of carbon dioxide into the atmosphere when it burns.
Synthetic chemists today have the ability to construct molecules of almost any atomic composition, creating new materials with any number of promising applications that range from sustainable energy and environmental remediation, to high-performance electronics.
Two prebiotic molecules - one related to DNA and the other to an amino acid - have been identified in a gas cloud near the center of the Milky Way.
Scientists have demonstrated that it's possible to store information in individual molecules, potentially paving the way for storage devices that could be thousands of times smaller than today.
Scientists at the University of Southern California (USC) have identified two molecules capable of killing cancer cells.
The asymmetry of biological molecules may have come from space, say French scientists.
Scientists at the Massachusetts Institute of Technology have successfully designed a computer chip comprising hundreds of tiny molecules.
