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. ...

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 ...

This is what a stretchy circuit looks like

Researchers in China have made a new hybrid conductive material—part elastic polymer, part liquid metal—that can be bent and stretched at will. Circuits made with this material can take most two-dimensional shapes and ...

A tango with tangled polymers

While statisticians are driven by real-world problems, U of S mathematics professor Chris Soteros is motivated by the more esoteric behaviour of long-chain molecules, such as polymers and DNA, and the mathematical problems ...

Engineers turn plastic insulator into heat conductor

Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic ...

Polymers that mimic chameleon skin

Biological tissues have complex mechanical properties – soft-yet-strong, tough-yet-flexible – that are difficult to reproduce using synthetic materials. An international team has managed to produce a biocompatible synthetic ...

Researchers discover a way to control the colour of OLEDs

Organic light-emitting diodes (OLEDs) are used in smartphones and televisions to facilitate the high-contrast display of colours. Conjugated polymers are also often employed as organic semiconductors in such diodes. Researchers ...

Custom sequences for polymers using visible light

Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. By simply ...

Novel adhesive and thermally stable epoxy resins

Epoxy resins or epoxies are organic compounds that can be hardened into adhesive materials with excellent thermal stability, mechanical strength, and chemical resistance. The hardening or 'curing' results from cross-linking ...

Scientists create multifunctional protein-polymer films

A team from MSU, with international and Russian colleagues, has found that mixing dendrimers (tree-like polymers) and proteins induces spontaneous multilayer films. They are easily formed and retain the activity and function ...

'Random walk' of heat carriers in amorphous polymers

The intrinsic structure of amorphous polymers is highly disordered with long, entangled molecular chains. They are usually considered as thermal insulators due to their ultra-low thermal conductivity. One effective way to ...

Printable, colorful camouflage with polymers

In nature, colors can serve as a form of communication, but they can also hide animals and plants, camouflaging them from sight. Researchers now report in ACS Applied Materials & Interfaces that they have developed polymers ...

Material gradients could strengthen polymer components

Combining flexible and stiff materials has bestowed bamboo with a strength-to-weight ratio that rivals steel. Gradually transitioning from a soft to hard substance allows the squishy squid to slice up prey with rigid, scissor-like ...
