LED-ing the way: A clean and convenient method to oxidize plastic surfaces for industry

13-Jun-2019

Polypropylene (PP) is everywhere, being one of the most widely used plastics in human life. A versatile material, its naturally inert surface can be modified for specific applications. Researchers at Osaka University have now developed a convenient light-driven process for oxidizing PP without ...

How ice particles promote the formation of radicals

Chemistry in clouds

10-Dec-2018

Certain molecules with fluorine, chlorine or bromine, together with water, can release harmful substances into the atmosphere. The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer ...

Radical approach for brighter LEDs

27-Nov-2018

Scientists have discovered that semiconducting molecules with unpaired electrons, termed 'radicals' can be used to fabricate very efficient organic-light-emitting diodes (OLEDs), exploiting their quantum mechanical 'spin' property to overcome efficiency limitations for traditional, non-radical ...

A new way to create molecules for drug development

Innovative process gives more control over free radicals

15-Oct-2018

Chemists at The Ohio State University have developed a new and improved way to generate molecules that can enable the design of new types of synthetic drugs. Researchers say this new method of forming reactive intermediates called ketyl radicals offers scientists a way to use catalysts to convert ...

Multiyear Tracking of Atmospheric Radicals

New method derive both short-lived atmospheric hydroxyl and chlorine radical concentrations over several years

13-Sep-2018

Hydroxyl radicals (OH) keep our atmosphere clean. They react away toxic gases such as carbon monoxide (CO), and slow climate warming by removing greenhouse gases like methane (CH4). In some parts of the atmosphere, chlorine radicals (Cl) can also help this purification process, for example in the ...

Tailored Polymers from a Printer

Efficient chain transfer for 3D-printing of tough photopolymers

10-Jul-2018

An ever-growing number of coatings, including varnishes and printing inks, as well as tooth fillings, are cured with light. Yet, homogenous, tailored, polymer networks cannot be produced, and the materials tend to be brittle, which limits the use of photopolymers in applications like 3D printing, ...

Rapid pair production: Detection of a new reaction path in the atmosphere

04-Apr-2018

Scientists have now observed a particularly rapid type of pair production in the laboratory: Hydrocarbons double when two peroxyl radicals react with each other. This means that stable products with the carbon skeleton of both peroxyl radicals are formed, which very likely will have a peroxide ...

Stable biradicals adding a new attraction to chemistry

Boron biradical in ground-state synthesized

26-Mar-2018

Researchers at the University of Würzburg in Germany have succeeded in twisting molecules so much that their double bonds have been completely destroyed. The result: unusually stable biradicals. Boron has a range of uses throughout everyday life, from laundry bleaches to heat-proof glass and ...

Better 'fingerprints' to detect elusive, valuable chemical compounds

28-Jun-2017

Imagine being able to see the entire Statue of Liberty and a small ant on its nose simultaneously. The drastic difference in size between the two objects would seem to render this task impossible. On a molecular level, this is exactly what a team led by Sandia National Laboratories chemists David ...

Defects at the spinterface disrupt transmission

Researchers put metal-oxides and organic magnets together; applications for electronics in sight

23-Sep-2016

Magnets made of organic materials have a number of advantages over the classic metal or alloy magnets. They are chemically more flexible, cheaper to make, and can be better adapted to various purposes and varying designs. In practice, researchers want to apply both types of magnets in electronics ...
