85th anniversary of the death of the chemist Fritz Klatte

11/02/2019

If there is a plastic that has the ability to fuel emotions, then it is polyvinyl chloride, better known by its abbreviation PVC. Although the German chemist Fritz Klatte (1880-1934) was not the person who discovered PVC, he did play what was an economically significant role in that he laid the foundations for the industrial production of the third most important plastic in the world today.

Directly-cooled electric motor made from polymer materials

05/02/2019

Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. Researchers are developing a new cooling concept that will enable polymers to be used as motor housing materials. And that’s not the only advantage of the new cooling concept: it also significantly increases the power density and ...

Stretchy solar cells a step closer

29/11/2018

Rice University scientists develop flexible organic photovoltaics with a chemical additive that mitigates the material's brittle qualities. At the right concentration, thiol-ene molecules infiltrate the polymer material and form a mesh that makes the entire material stretchable without losing efficiency.

Acrylic patented 90 years ago

23/11/2018

Chemically speaking, it is merely one step from plastics made out of polymethacrylate (PMA) to Perspex, i.e. polymethyl methacrylate (PMMA), production of which began at Röhm & Haas AG in 1928 (Hölscher 1972, 121). In contrast to acrylic acid, methacrylic acid has a methyl group (CH3) and/or is derived ...

New material cleans and splits water

16/11/2018

Researchers at EPFL's Institute of Chemical Sciences and Engineering have developed a photocatalytic system based on a material in the class of metal-organic frameworks. The system can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and used further.

A record-long polymer DNA negative

13/11/2018

A fragment of a single strand of DNA, built of the nucleobases cytosine and guanine, can be imprinted in a polymer - this has been shown by chemists from Warsaw, Denton and Milan. The resulting artificial negative, with a record-long length, functions chemically like a normal strand of deoxyribonucleic acid. This ...

Like the earthworm: new breathing material lubricates itself when needed

12/11/2018

Earthworms are always clean, even if they come from moist, sticky soil. They owe this to a dirt-repellent, lubricating layer, which forms itself again and again on its skin. Researchers at INM have now artificially recreated this system of nature.

Acrylic patented 90 years ago

28/10/2018

90 years ago, on 27. October 1928, Röhm & Haas AG, Darmstadt, received a patent for an innovative new plastic with the awkward name polymethyl methacrylate (PMMA). German Imperial Patent (DRP) 656642 was the result of sixteen years of research in the acrylate chemistry field. (...)
