Today's KNOWLEDGE Share Plastic-eating enzyme identified in wastewater microbes: Plastic pollution is everywhere, and a good amount of it is composed of polyethylene terephthalate (PET). This polymer is used to make bottles, containers and even clothing. Now, researchers report in ACS’ Environmental Science & Technology that they have discovered an enzyme that breaks apart PET in a rather unusual place: microbes living in sewage sludge. The enzyme could be used by wastewater treatment plants to break apart microplastic particles and upcycle plastic waste. Microplastics are becoming increasingly prevalent in places ranging from remote oceans to inside bodies, so it shouldn’t be a surprise that they appear in wastewater as well. However, the particles are so tiny that they can slip through water treatment purification processes and end up in the effluent that is reintroduced to the environment. But effluent also contains microorganisms that like to eat those plastic particles, in

Today's KNOWLEDGE Share Plastics are stronger and lighter thanks to carbon nanotubes derivatives Reducing the environmental impact caused by plastics can be addressed through different strategies, such as the manufacture of more durable plastics or recycling. In general, there are two main types of plastics. The first is thermoplastics, which can be melted and molded to form other objects, although their mechanical properties weaken if they are melted several times. And the second,  thermosets , do not melt at high temperatures, since the chains of the polymers that form them are intertwined by chemical bonds. Thermoset plastics have advantageous properties compared to thermoplastics. They tend to have a higher resistance to impact and mechanical stress, although they are also more brittle. Epoxy resin, silicone or melamine are examples of thermoset plastics, commonly used in construction. To make these plastics stronger, engineers add reinforcement materials such as carbon fibers.

Today's KNOWLEDGE Share Marie Curie, née Skłodowska-The Nobel prize in 1911 Marie Curie was a physicist and chemist who became the first woman to win a Nobel prize. Along with her husband Pierre, she discovered two elements: polonium and radium. She also carried out pioneering research into radioactivity. Born Maria Skłodowska in Warsaw on 7 November 1867, Marie moved to Paris in 1891 to study physics, chemistry and maths at the University of Paris, where she earned two degrees, supporting herself through her studies by tutoring in the evenings. There she met Pierre Curie, who worked at the university, and they married in 1895. The couple set up a joint laboratory in a basement, building their own equipment for their experiments. At the time no one knew about the effects of radioactivity on the body, so they handled the elements they used in their research without any of the precautions or protective clothing we would use today. Marie even kept vials of what she was working on in h

Today's KNOWLEDGE Share Toray Advanced Composites announces launch of high-performance Toray Cetex® PESU thermoplastic composite material Toray Advanced Composites, a leading innovator in advanced material technology, today announces the launch of Toray Cetex® TC1130 PESU thermoplastic composite material. This high-performance thermoplastic composite material is specifically engineered to address the growing need for lightweight and environmentally sustainable materials in aircraft interior applications, offering significant benefits to the aerospace industry. Suited for monolithic and thermoplastic-based sandwich panel constructions, Toray Cetex® TC1130 PESU (PolyEtherSulphone) continuous fiber reinforced thermoplastic composite enables the creation of mono-material sandwich structures when combined with core materials of the same chemistry. Compared to materials currently used, this not only achieves additional weight savings and cost-effective post-processing, but also ensures f
