Researchers at The Education University of Hong Kong (EdUHK) have contributed to a study revealing that conventional theories ...

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 ...

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

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 ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...

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 ...

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 ...

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