Spectroscopic Technique Enables the Study of Organic Photovoltaics
A new spectroscopic method now makes it possible to measure and visualise the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr Yana Vaynzof, a physicist at... -
Lensless Endoscope Captures 3D Images of Objects Smaller than a Cell
Researchers have developed a new self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical or mechanical components, the tip of the endoscope measures... -
Researchers Turn Off Backscattering to Improve Optical Data Transmission
Engineers at the University of Illinois have found a way to redirect misfit light waves to reduce energy loss during optical data transmission. In a study, researchers exploited an interaction between light and sound waves to... -
Optimizing Farmland Use for Crops, Solar Electricity Production
Purdue University professors are questioning what else fertile farmland can be used for with a new multidisciplinary project researching how to improve future sustainability by simultaneously utilizing crop fields for solar... -
Installing Solar on Agricultural Lands Maximizes Efficiency
The most productive places on Earth for solar power are farmlands, according to an Oregon State University study. The study, published today in the journal Scientific Reports, finds that if less than 1% of agricultural... -
Two-in-One Contrast Agent for Medical Imaging
Magnetic resonance imaging (MRI) visualizes internal body structures, often with the help of contrast agents to enhance sensitivity. A Belgian team of scientists has now developed a bimodal contrast agent suited for two imaging... -
Non-Invasive Imaging Method Spots Cancer at the Molecular Level
Researchers for the first time have combined a powerful microscopy technique with automated image analysis algorithms to distinguish between healthy and metastatic cancerous tissue without relying on invasive biopsies or the use...

Thin Film Hides Objects from Infrared Detectors
Researchers at the Chinese Academy of Sciences have developed an aerogel film made of DuPont Kevlar fibers that makes objects invisible to infrared detectors. A successful method for hiding objects from heat-sensing cameras could be... -
Measuring and Self-Adjusting Spectral Power Distribution of LED Systems
Researchers from the Catalonia Institute for Energy Research (IREC) at the University of Barcelona and its spin-off Ledmotive Technologies in Spain have combined two computational methods to enable solid-state lighting (SSL) to measure and... -
Perovskite NIR LED with Record External Quantum Efficiency
Researchers at Linköping University (LiU) in Sweden have produced near-infrared (NIR) light-emitting diodes (LED) of perovskite with a record external quantum efficiency of 21.6%. Because perovskites have good light-emitting properties and... -
Optical Tweezers Use Fluid Flow Instead of Light
Researchers from the universities of Glasgow, Bristol and Exeter have collaborated to create an entirely new kind of optical tweezers that use fluid flow instead of light to control particles of any material and hold light-sensitive biological... -
First of its Kind Quantum Sensor to Detect Single Photons
A new, groundbreakingly effective sensor developed by researchers at the University of Waterloo in Ontario (Canada) is the first of its kind, based on semiconductor nanowires, that can detect photons. The research breakthrough promises to... -
Graphene-Based Wearable Health Monitoring and Spectroscopy Devices
The Graphene Flagship has introduced more than 20 graphene-based prototypes at Mobile World Congress (MWC) 2019. Four of the inventions were developed by Graphene Flagship partner ICFO — the Institute of Photonic Sciences, based in Barcelona,... -
Portable and Label-Free Imaging of Molecules and Cells
A custom portable optical imaging system developed at the University of Illinois at Urbana-Champaign (UIUC) visualizes the dynamic cellular and molecular features in freshly removed or biopsied breast tissue specimens, as opposed the...
