Molecules that act as connected wheels can hold long molecular chains together to modify the properties of soft polymers. Molecules that act as connected wheels can hold long molecular chains together ...

Semiconducting polymer nanomaterials are advanced π-conjugated polymers with alternating double and single bonds, which allow for π-electron delocalization and intermolecular π−π interactions. Unlike ...

The molecular weight (MW) is the total atomic weight of a molecule. The MW is determined by summing the mass of all of the individual atoms in a molecule. The molecular weight of a polymer is directly ...

Most people are aware that plastic waste is a problem. Almost all types of plastics that we use in our everyday lives are derived from fossil sources. When they end up in the environment, they cause ...

This illustration shows the C1 polymer formation, where the Pd-catalyst (red spere) is linearly combining a number of diazoacetate monomers (transparent sphere) to form the polymer main chain. For ...

What if a complex material could reshape itself in response to a simple chemical signal? A team of physicists from the University of Vienna and the University of Edinburgh has shown that even small ...

Polymers can be cast at low pressures, rather than injection-molded, to produce engineering-grade components for downhole use. Like many other industry sectors, the upstream oil and gas industry has ...

Polymer-based dielectrics are widely used in different electrical and electronic devices like capacitors, power transmission cables, and microchips. To adapt to different working conditions, a range ...

Molecules that act as connected wheels can hold long molecular chains together to modify the properties of soft polymers. Rotaxanes are interlocked molecular structures with a linear ‘axle’ molecule ...
