New method uses noise to make spectrometers more accurate

Optical spectrometers are instruments with a wide variety of uses. By measuring the intensity of light across different wavelengths, they can be used to image tissues or measure the chemical composition of everything from ...

Forging molecular bonds with green light

QUT researchers have created a new molecular coupling tool employing both green light and pH triggers that has potential for use in applications such as drug delivery and 3-D cell culture platforms.

Light swirls provide insights into the quantum world

A new method uses swirls of light to enable researchers to observe previously invisible quantum states of electrons. The method was developed by physicists from Martin Luther University Halle-Wittenberg (MLU) and an international ...

Researchers develop photonic crystal light converter

Spectroscopy is the use of light to analyze physical objects and biological samples. Different kinds of light can provide different kinds of information. Vacuum ultraviolet light is useful as it can aid people in a broad ...

Giant clams manipulate light to assist their symbiotic partner

Special cells in giant clams shift the wavelength of light to protect them from UV radiation and increase the photosynthetic activity of their symbionts, shows research from King Abdullah University of Science and Technology—originally ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...
