Strain-induced isomerization of molecular chains

National University of Singapore scientists have demonstrated a strain-induced structural rearrangement of one-dimensional (1D) metal-organic molecular chains for potential use in fabricating functional nanostructures.

Sensing sweetness on a molecular level

Whether it's chocolate cake or pasta sauce, the sensation of sweetness plays a major role in the human diet and the perception of other flavors. While a lot is known about the individual proteins that signal "sweet," not ...

Researchers reveal molecular basis of vision

Researchers have solved the three-dimensional structure of a protein complex involved in vertebrate vision at atomic resolution, a finding that has broad implications for our understanding of biological signaling processes ...

Diamonds are forever: New foundation for nanostructures

Devices smaller than the width of a human hair are key to technologies for drug delivery, semiconductors, and fuel production. But current methods for fabricating these micro- and nanostructures can be expensive and wasteful.

Chemical structure

A chemical structure includes molecular geometry, electronic structure and crystal structure of a chemical compound. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together. Molecular geometry can range from the very simple, such as diatomic oxygen or nitrogen molecules, to the very complex, such as protein or DNA molecules. Molecular geometry can be roughly represented using a structural formula. Electronic structure describes the occupation of a compound's molecular orbitals.
