There are billions of people using WhatsApp, Telegram, iMessage or even Instagram for group chats. These platforms are ideally designed for “personal conversations” — more specifically individual ...

Ultraviolet (UV) photon detection is becoming increasingly important in our quest to understand the fundamental building blocks of our universe. Basic properties of neutrinos and Dark Matter are ...

Real-time spectroscopy is a powerful tool for studying dynamic chemical and physical systems. Unfortunately, conventional spectrometers are relatively slow, and do not permit real-time measurements.

A specific wavelength of ultraviolet (UV) light is not only extremely effective at killing the virus which causes COVID-19, but is also safer for use in public spaces, finds new CU Boulder research.

Engineers have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing and communication systems.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
