‘Vegan spider silk’ provides sustainable alternative to single-use plastics

Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products. The researchers, from the University of Cambridge, created a polymer film by mimicking the properties of spider silk, one of the strongest materials…

New way to 3D-print custom medical devices to boost performance and bacterial resistance

Using a new 3D printing process, University of Nottingham researchers have discovered how to tailor-make artificial body parts and other medical devices with built-in functionality that offers better shape and durability, while cutting the risk of bacterial infection at the…

Bacteria-sized robots take on microplastics and win by breaking them down

Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process, but getting…

Online ‘library of properties’ helps to create safer nanomaterials

Researchers have developed a ‘library of properties’ to help identify the environmental impact of nanomaterials faster and more cost effectively. Whilst nanomaterials have benefited a wide range of industries and revolutionised everyday life, there are concerns over potential adverse effects…

Bioinspired acid-catalyzed C2 prenylation of indole derivatives

Terpenoids are omnipresent in almost all living organisms. Prenylated indoles are prominent representatives that usually display potent medicinal properties (e.g. tryprostatin B). Therefore, significant efforts have been devoted to indole prenylation over the past decades. The known protocols often require…

First cells reprogrammed to make synthetic polymers; also making them resistant to viruses

Scientists create cells – with a synthetic genome – and instruct them to make polymers from artificial building blocks for the first time; the new bacteria are also resistant to viral infections

Nanofibrous filters for PM2.5 filtration

In a paper published in NANO , the author reviewed many kinds of nanofibrous filters including the component, preparation process, and application performances to provide directional guidance for improvement of the air purification field. Poor air quality is worldwide recognized…

Synthetic breakthrough for controlling functional group assembly over chaotic mixing

The multifunctional porous solids with diverse functionalized linkers have been utilized as promising materials for various applications in energy, environmental and biomedical areas. Although their emerging properties are ascribed to varying pore types resulting from combinations of functional groups, the…

Scientists find solution to measure harmful plastic particles in human sewage

Scientists have got up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics. As the way microplastics are measured and counted varies from place to place, there is no agreed understanding of…

New research finds advanced shoe technology reduces top race times for elite athletes

For elite runners competing in long-distance races, every second counts. So when Nike introduced “advanced shoe technology” in 2017, questions arose about whether the new design would significantly affect performances in professional sports. A new paper published in Frontiers in…

Illuminating invisible bloody fingerprints with a fluorescent polymer

Careful criminals usually clean a scene, wiping away visible blood and fingerprints. However, prints made with trace amounts of blood, invisible to the naked eye, could remain. Dyes can detect these hidden prints, but the dyes don’t work well on…

With this new science, plastics could see a second life as biodegradable surfactants

Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP) have discovered a chemical process that provides biodegradable chemicals, which are used as surfactants and detergents in a range of applications, from discarded plastics.

Plastics could see a second life as biodegradable surfactants

Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of…

Materials scientists use frontal polymerization to mimic biology, reimagine manufacturing

A simple plastic water bottle isn’t so simple when it comes to the traditional manufacturing process. To appear in its final form, it has to go through a multi-step journey of synthetic procedure, casting, and molding. But what if materials…

Contact lenses poised to detect cancer, treat disease and replace digital screens

Newly-published “contact lens technologies of the future” paper reviews innovative uses for disease detection and therapy, drug delivery, vision enhancement and mor

Plasmon-coupled gold nanoparticles useful for thermal history sensing

Researchers have demonstrated that stretching shape-memory polymers embedded with clusters of gold nanoparticles alters their plasmon-coupling, giving rise to desirable optical properties. One potential application for the material is a sensor that relies on optical properties to track an object…

Fast-acting, color-changing molecular probe senses when a material is about to fail

CHAMPAIGN, Ill. — Materials that contain special polymer molecules may someday be able to warn us when they are about to fail, researchers said. Engineers at the University of Illinois Urbana-Champaign have improved their previously developed force-sensitive molecules, called mechanophores,…
