Regulating the absorption spectrum of polydopamine

Polydopamine (PDA) is an advanced functional material and its emergent light absorption properties make it crucial for applications in materials science. However, it is challenging to rationally design and regulate PDA absorption ...

Saturable plasmonic metasurfaces for laser mode locking

Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear regime, their applications ...

Lasers etch a 'perfect' solar energy absorber

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

Turning up the heat on antibacterial-resistant diseases

Photothermal therapy (PTT) is a proposed treatment for diseases like antibacterial-resistant infections and cancer, but despite over a decade of research, scientists have been unable to find a safe and effective chemical ...

Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers ...

Image: Hubble eyes an emitting galaxy
