A new strategy to create blue light from a promising material

A Florida State University research team has developed a new way to create blue light from a class of materials that shows enormous potential for optoelectronic devices, including solar cells, light-emitting diodes (LEDs) ...

Identifying a new, cleaner source for white light

When early humans discovered how to harness fire, they were able to push back against the nightly darkness that enveloped them. With the invention and widespread adoption of electricity, it became easier to separate heat ...

Sizing up special light to downsize particle accelerators

Researchers have developed a new technique to better measure special "terahertz" light. This light travels in waves longer than the infrared light that is beyond what the human eye perceives. The new sampling technique preserves ...

Light-emitting electrochemical cells for recyclable lighting

A low-cost and easy-to-manufacture lighting technology can be made with light-emitting electrochemical cells. Such cells are thin-film electronic and ionic devices that generate light after a low voltage is applied. Researchers ...

Chemists harness the sun to upcycle plastic waste

Chemists at Cornell University have discovered a way to use light and oxygen to upcycle polystyrene—a type of plastic found in many common items—into benzoic acid, a product stocked in undergraduate and high school chemistry ...

Mapping the movement of white dwarfs of the Milky Way

White dwarfs were once normal stars similar to the sun but then collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. However, a recent study from Lund University ...

LED streetlights contribute to insect population declines: study

Streetlights—particularly those that use white light-emitting diodes (LEDs)—not only disrupt insect behavior but are also a culprit behind their declining numbers, a new study carried out in southern England showed Wednesday.
