New research shows that miniscule amounts of impurities in vacuum are being incorporated into OLEDs during fabrication and leading to large variations in lifetime. By reducing the time OLEDs spend in the deposition chamber during fabrication, impurities can be...
Ever wondered how the fate of champagne bubbles from their birth to their death with a pop enhances our perception of aromas? These concerns, which are relevant to champagne producers, are the focus of a special issue of EPJ...
An illustration of aquaporin's effect on cells. Credit: M. Shapiro Laboratory/Caltech Genes tell cells what to do—for example, when to repair DNA mistakes or when to die—and can be turned on or off like a light switch. Knowing which genes...
Using ultrafast imaging of moving energy in photosynthesis, scientists have determined the speed of crucial processes for the first time. This should help scientists understand how nature has perfected the process of photosynthesis, and how this might be copied to...
Ice crystals form around a minuscule particle in the very first seconds of the formation of an ice cloud.Credit: Pacific Northwest National Laboratory Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and...
LLNL scientists synthesized a long sought-after five-ring nitrogen compound under pressure starting from a mixture of cesium azide (CsN3) and molecular nitrogen. Credit: Adam Connell/TID Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with University of South Florida theorists recently...
Antiaromatic planar norcorrole molecules form close face-to-face stacked structures with increased aromaticity. This behavior is quite different from that of planar aromatic molecules. This result is the first experimental proof for the theoretical prediction that the stacking of antiaromatic...
Correlation between cryo-transmission electron microscope (TEM) images and the crystal structure. (l) TEM image showing three colliding clusters. The scale bar is 10 nm. (r) Relative positions of molecules derived from the X-ray diffraction crystal structure are overlaid (brown)...
The formation of exciton-polaritons through strong light-matter coupling is a promising strategy for producing electrically pumped carbon-based lasers. Scientists from Heidelberg University and the University of St Andrews (Scotland) have now, for the first time, demonstrated this strong light-matter...
A silver-based catalyst material with a porous honeycomb-like structure, developed by the MIT team, can selectively transform carbon dioxide (CO2) to carbon monoxide (CO).Image: Christine Daniloff/MIT New catalyst provides design principles for producing fuels from carbon dioxide emissions. A new catalyst...
MIT researchers have developed a way to isolate genetic circuits within individual synthetic “cells,” preventing the circuits from disrupting each other.Image: Nick Fair Encapsulating molecular components in artificial membranes offers more flexibility in designing circuits. Synthetic biology allows scientists to design...
