High-performance supramolecular polymer from a simple molecule

High-performance supramolecular polymer from a simple molecule

Chemistry

By Pablo Ortiz

Turning simple, individual molecules into complex, interconnected materials is the core of polymer chemistry. There is currently an increasing demand for materials with sophisticated properties such as self-healing and reusable adhesivity. However, achieving polymers with such functionalities generally demands higher structural complexity, synthetic difficulty, and cost. Now, a team of chemists has designed a supramolecular […]

Author: Roberto D’Agosta is an Ikerbasque Research Professor at ETSF and the Department of Materials Physics in the Faculty of Chemistry at the UPV/EHU in San Sebastian. Francesca Baletto, senior lecturer at King’s College London, read and commented the manuscript. Every single moment, nature exploits catalysis to make or improve specific chemical reactions. Catalysts facilitate […]

Many methods can be used to synthesise non-molecular inorganic solids. Some solids can be prepared by a variety of routes but others, especially those that are not thermodynamically stable, may be much more difficult to prepare and may require special methods. Non-molecular inorganic solids can also be prepared in various forms, as fibres, films, foams […]

By Isabel Perez Castro

From nucleic acids to proteins and sugar chains, all life is made up of polymers, large molecules made up of sequences of small units called monomers. However, how these macromolecules first appeared on the surface of Earth is still controversial. It is generally assumed that, right before life started, our planet was covered in very […]

A class of materials of utmost fundamental and applied interest is that of semicrystalline polymers. Actually, all solid synthetic polymers are, in general, partly crystalline and partly amorphous. The degree of crystallinity depends on the polymer structure and on how the solid is prepared. Rapid cooling of the molten polymer favors formation of an amorphous […]

The scattering of conduction electrons in metals owing to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has the consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered and […]

By DIPC

Metal complexes are typically regarded as catalysts that convert organic substrates into more valuable compounds; however, to date, catalytic transformations of metal complexes are practically unknown and represent a complete new way of thinking in catalysis. Their development can expand the scope of bioorthogonal chemical reactions to inorganic substances and metal-based prodrugs, fostering the creation […]
