The advent of on-surface chemistry under vacuum has vastly increased our capabilities to synthesize carbon nanomaterials with atomic precision. Among the types of target structures that have been synthesized by these means, one-dimensional graphene nanoribbons (GNRs) have probably attracted the most attention, and for a good reason: the enormous tunability of GNRs’ electronic properties is […]

  The reason that ibuprofen treats headaches and ice cream tastes sweet is that their chemical components fit perfectly into certain receptors in your body. The better a drug or flavor molecule fits with its matching receptor, the more effective the medicine or tastier the treat. But an interesting quirk of nature is that many […]

The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United States to Canada and back. Sadly, the population of monarch butterflies is declining, and the future of the monarch migratory phenomenon is uncertain. Scientists can study migrations by […]

Molecules when excited from their ground state (S0) to their lowest electronically excited states often change their electronic structure considerably, which impacts on a range of important molecular properties. For example, the reactivity of a molecule in its excited state often differs markedly from that in its S0 state. Also, the charge distribution within a […]

In spintronics, new memory and logic devices are being developed based on the use of spins of nuclei, atoms, or molecules, instead of electronic charges. The main advantages are an improved energy efficiency and speed of operation to store and process information. The ability of organic molecules to maintain magnetic multistability in nanoscale junctions will […]

Adsorption commonly is understood as the reversible binding of molecules and atoms from the gaseous or liquid phase on surfaces, mostly of highly porous adsorbent media. In chemisorption a single layer of molecules, atoms or ions is attached to the adsorbent surface by chemical bonds; in physisorption only van der Waals forces are involved. Adsorption […]
