Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a plasmonic gold nanohole substrate further doubles exciton diffusivity. By mitigating the limited diffusivity of singlet excitons in organic semiconductors, this approach offers a new strategy for improving optoelectronic technologies.

Sustainability commitments have serious consequences

Amid increasingly stiff competition for capital, one way for a business to stand out is to make strong social impact pledges. For example, companies can voluntarily commit to environmental impact goals in hopes of attracting sustainability-minded investors and lowering the cost of capital. However, it isn't easy to tell whether these commitments, in and of themselves, make a difference in the marketplace—or, for that matter, to the planet.

Climate change is rewriting England's 'green and pleasant' story

In 1804, William Blake wrote in his poem Jerusalem of England's "green and pleasant" land. This idealized vision of English pastoral has resonated through two centuries, fusing the character of the nation with its landscape—those "mountains green" and "pleasant pastures."
