23/11/2018Chemically 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 ...
16/11/2018Researchers 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.
13/11/2018A 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 ...
12/11/2018Earthworms 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.
28/10/201890 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. (...)
11/10/2018On 11 October 1952, Theodor Heuss, then Federal President of the Federal Republic of Germany, officially opened the first “Plastics Trade Fair and Exhibition”, laying the foundation for the success story now known as the K Trade Fair in Düsseldorf.
18/09/2018A team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) presents alternative approaches for versatile future applications of plastic magnets.
10/09/2018A transparent material can “answer” temperature changes or, in the future, the presence of chemical substances and toxins with a color Change.
28/08/2018Geckos, spiders and beetles have shown us how to do it: thanks to special adhesive elements on their feet, they can easily run along ceilings or walls. The science of bionics tries to imitate and control such biological functions, for technological applications and the creation of artificial materials. A research team from Kiel University (CAU) has now succeeded in boosting the adhesive ...
26/07/2018Thin mulch films made of polyethylene are used in agriculture in numerous countries, where they cause extensive soil contamination. Researchers at ETH Zurich and Eawag have now identified an alternative: films made of the polymer PBAT biodegrade in soils.
