Switched on IR-active organic pigments
In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. A team of chemists have now produced an unusual organic pigment, which is "switched on" by an electrical charge to become a potent dye that absorbs l.....»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
An international team led by scientists at City University of Hong Kong has found a flexible metal-organic framework (MOF) with one-dimensional channels that acts as a "molecular trapdoor" to selectively adsorb gases, such as carbon dioxide, in respo.....»»
Diatom surprise could rewrite the global carbon cycle
When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide.....»»
Organic compounds show promise as cheaper alternatives to metal photocatalysts
Organic compounds that can be sustainably and affordably mass-produced show promise as replacements for expensive metal photocatalysts, according to a new report published July 17......»»
Study shows how organic molecules impact gold nanoparticles" electrochemical properties
A new study shows how organic molecules greatly influence the redox potential of gold nanoparticles, with differences up to 71 mV. Using experiments and computer simulations, the study highlights the important role of capping agents in controlling th.....»»
Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
Chlorinated flame retardants found to affect avian embryonic development
Short-chain chlorinated paraffins (SCCPs) were listed under the category of globally controlled persistent organic pollutants (POPs) by the Stockholm Convention in 2017. However, SCCPs toxicity, particularly its developmental toxicity in avian embryo.....»»
Coastal dealers talk insurance costs, hurricane preparation know-how
NOAA expects a more active Atlantic hurricane season. Dealers, already wary of higher insurance cost,s are monitoring it......»»
New class of organic nanoparticles shows promise for diverse applications
Nanoparticles have a wide variety of applications, from drug delivery to electronics to air purification. Their small size and tunable properties make them particularly valuable for technological advancements and scientific research. When polymers ma.....»»
Investigating variation in the permafrost active layer over the Tibetan Plateau from 1980 to 2020
The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more sensitive to global warming. The active layer is a cruc.....»»
Exim vulnerability affecting 1.5M servers lets attackers attach malicious files
Based on past attacks, it wouldn’t be surprising to see active targeting this time, too. Enlarge More than 1.5 million email servers are vulnerable to attacks that can deliver executable attachments to user accounts,.....»»

Chemists develop robust molecule that gives organic electronic devices a boost
RIKEN chemists have developed a molecule that enhances the performance of organic electronic devices and is also more stable than previous alternatives, raising the chances that it could be used in industrial manufacturing processes. The study is pub.....»»
Scientists propose new solutions to keep drinking water safe as pesticide use skyrockets worldwide
Water scientists from Australia and China have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems......»»
Nanoparticle-based delivery system could offer treatment for diabetics with rare insulin allergy
Up to 3% of people with diabetes have an allergic reaction to insulin. A team at Forschungszentrum Jülich has now studied a method that could be used to deliver the active substance into the body in a masked form—in the form of tiny nanoparticles......»»
Photosynthesis powers our world, but what fuels this fundamental process?
It's hard to overstate the importance of photosynthesis, the biochemical pathway by which plants, algae, and certain bacteria convert the sun's energy into the organic material that feeds the entire living biosphere. But there are still aspects of th.....»»
Scientists develop efficient and stable hybrid perovskite-organic LEDs with external quantum efficiency exceeding 40%
Tandem LEDs offer an effective way to integrate different light-emitting technologies for better display that meets Rec. 2020 color gamut standard. Now, scientists in China have developed a stable, efficient and high-color purity green LED with a tan.....»»
Promising interlayer sensitization strategy for the construction of high-performance blue hyperfluorescence OLEDs
Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are promising candidates for organic light-emitting diodes (OLEDs) with narrow electroluminescence (EL) spectra. Scientists in China propose an interlayer sensitization stra.....»»
Sicily"s Catania airport reopens after Mount Etna eruption
