A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses. Natural and humanmade physical structures all lose energy, and scientists ...

Direct laser processing of material surfaces is a powerful technique for modifying the optical and electrical properties of those materials, often through the creation of nanostructures on the surface ...

Spectroscopy analyzes light to identify a celestial object's composition. Each element absorbs light at unique wavelengths, creating a spectral "fingerprint". The amount of light absorbed indicates ...
