World's smallest light-emitting diode produced

New ceramic diaphragm enables 2500× higher pixel density

26-Nov-2025 - Researchers at ETH Zurich are producing organic light-emitting diodes (OLEDs) on the nanoscale - they are around a hundred times smaller than a human cell. This not only makes ultra-sharp screens and microscopes possible. The pixels are so small that new wave optics applications are conceivable. ...

New sensor identifies gases more accurately with a ‘speed camera’ system

Modular platform enables a wide range of applications: from early detection of diabetes and leaks in the chemical industry to freshness monitoring of fruit and vegetables

01-Oct-2025 - From breath analysis to explosive detection: these applications require reliable electronic ‘noses’. Unfortunately, current technology often falls short. That is why researchers at KU Leuven have developed a flexible sensor platform that not only detects gases, but also records their speed—like a ...

Lithuanian chemists developed oxygen sensors that can be applied from food packaging to cancer diagnostics

Record-breaking sensitivity

16-Sep-2025 - Researchers at Kaunas University of Technology (KTU), Lithuania, have developed new organic compounds that act as highly sensitive oxygen sensors. These sensors can accurately detect even the slightest amounts of oxygen in the environment – information that is crucial in situations where oxygen ...

Simple color-changing sensor quickly identifies poisonous gases

A durable, paper-based sensor array enables quick and accurate measurements within minutes

11-Aug-2025 - Not all poisonous gases have a smell or a color. But a tiny grid of pastel- and candy-colored squares that effectively “sniffs” out hazardous chemicals in the air such as chlorosarin — a highly toxic nerve agent — could help detect them. Researchers report in ACS Sensors that the colorful ...

Built-in smart sensors can prevent lithium-ion battery fires before they start

By monitoring temperature and chemical changes in real time, the sensors offer increased safety for electric vehicles and energy storage systems

22-Jul-2025 - New smart sensors can help detect dangerous internal failures in lithium-ion batteries before they escalate into fires or explosions, say researchers from the University of Surrey. Lithium-ion batteries are at the heart of the global shift to electric vehicles and renewable energy – but when they ...

An elegant method for the detection of single spins using photovoltage

This could lead to a much more compact design of quantum sensors

17-Apr-2025 - Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally ...
