Ancient meteorite could reveal the origins of life on Earth

A 4.6-billion-year-old meteorite found in the laying in the imprint of a horseshoe is likely a remnant of cosmic debris left over from the birth of the solar system and could answer questions about how life began on Earth.

A new fuel cell electrolyte

As far back as the 1930s, inventors have commercialized fuel cells as a versatile source of power. Now, researchers from Japan have highlighted the impressive chemistry of an essential component of an upcoming fuel cell technology.

Exoskeletal microstructure of extremely hard coconut crab claws

The NIMS Research Center for Structural Materials and the Okinawa Churashima Foundation Research Center jointly ascertained the microstructure and chemical composition of the extremely tough exoskeletons of coconut crab claws, ...

Machine learning aids in materials design

A long-held goal by chemists across many industries, including energy, pharmaceuticals, energetics, food additives and organic semiconductors, is to imagine the chemical structure of a new molecule and be able to predict ...

Enantiomorph distribution maps for metals and metallic alloys

Left- or right-handedness is a symmetry property that many macroscopic objects also exhibit and which is of immense importance, particularly for the bioactivity of organic molecules. Chirality is also relevant for physical ...

Study polypharmacology earlier in drug discovery, say researchers

Polypharmacology—the ability of a drug to affect more than one protein—should be studied early in the drug discovery pathway, and constantly monitored as the chemical structure is optimized in the design of the clinical ...

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.
