Researchers Demonstrate a New Level of Stretchability of Photodetectors

Semiconductors are moving away from rigid substrates, which are cut or formed into thin discs or wafers, to more flexible plastic material and even paper thanks to new material and fabrication discoveries.

A Nanocomposite Could Help Improve Medical Imaging and Security Screening

A nanocomposite that absorbs X-rays and then, with nearly perfect efficiency, re-emits the captured energy as light, could help to improve high-resolution medical imaging and security screening.

Novel Computational Model Accurately Predicts the Properties of Photonics Materials

Researchers from the Singapore University of Technology and Design (SUTD) have designed a novel computational model that accurately predicts the properties of photonics materials, paving the way for next-generation photonics devices.

Study Illustrates Metasurface-Driven Optically Variable Devices for Anti-Counterfeiting

The increasing risk of advanced counterfeits always poses a need for a security device that can combat them. A technology never known before can be utilized in security devices. However, it is hard to make a comparison of their strengths as no standards were available to quantify their performance.

Novel Laser Spectrometer for Highly Precise Measurement of Greenhouse Gases

Nitrous oxide (N2O) and carbon monoxide (CO) are important drivers in global warming. However, there are many difficulties in reliable monitoring, especially for N2O, as the concentration of N2O in atmospheric is only a few hundred parts per billion.

QUEST Researchers Move Closer to Developing More Accurate Optical Atomic Clocks

Laser beams can do more than just heat things up; they can cool them down too. That is nothing new for physicists who have devoted themselves to precision spectroscopy and the development of optical atomic clocks.

Researchers Predict the Existence of Split Photons

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, according to a study from Dartmouth and SUNY Polytechnic Institute researchers.

Synchronisation is More Readily Achieved in Many Systems than Previously Thought

Physicists from Trinity College Dublin have unlocked the secret that explains how large groups of individual "oscillators" – from flashing fireflies to cheering crowds, and from ticking clocks to clicking metronomes – tend to synchronise when in each other's company.

Ultra-Rapid Cryo-Arrest Microscope for Observing Molecular Patterns of Life

Fluorescence light microscopy has the unique ability to observe cellular processes over a scale that bridges four orders of magnitude. Yet, its application to living cells is fundamentally limited by the very rapid and unceasing movement of molecules that define its living state.

Losing Isn’t Always Bad: Gaining Topology from Loss

Losing particles can lead to positive, robust effects. An international collaboration has demonstrated a novel topology arising from losses in hybrid light-matter particles, introducing a new avenue to induce the highly-prized effects inherent to conventional topological materials, which can potentially revolutionise electronics.
