Polymer coating cools down buildings

With temperatures rising and heat-waves disrupting lives around the world, cooling solutions are becoming ever more essential. This is a critical issue especially in developing countries, where summer heat can be extreme ...

Spontaneous synthesis of homogenous polymer networks

Nagoya researchers developed a spontaneous polymer network synthesis that allowed for the preparation of gels containing narrow molecular weight distribution polymers. The gel networks showed swelling properties that were ...

Cultivating microtissues to replace animal testing

For the replacement of animal testing with alternatives in medical research, complex microtissues need to be cultivated. Researchers from Empa have developed a special polymer scaffold for three-dimensional cell cultures. ...

Bacteria-fighting polymers created with light

Hundreds of polymers that could kill drug-resistant superbugs in novel ways can be produced and tested with light, using a method developed at the University of Warwick. The new methodology may identify antimicrobials for ...

Biomimetic micro/nanoscale fiber reinforced composites

Over hundreds of millions of years of evolution, nature has produced a myriad of biological materials that serve either as skeletons or as defensive or offensive weapons. Although these natural structural materials are derived ...

Designer polymers on demand

When jewelers create a necklace, they control the order and number of each bead or jewel they use to form a desired pattern. It's been challenging for scientists to do the same thing when designing polymers—until now. In ...

Research collaboration could reshape injection molding

As Ralph Colby peers at the microscope image in front of him, he thinks he can make them out—"shish kebabs," as polymer scientists call them. Nobody knows for sure what they are, but these shapes that appear at seemingly ...
