Chemists have succeeded in specifically controlling the setup of precision polymers by light-induced chemical reactions. The new method allows for the precise, planned arrangement of the chain links, ...

Mastering how to completely control the exact monomer sequence of synthetic polymers is the ultimate key for establishing true biomimetic macromolecular chemistry. A versatile one-pot approach for the ...

The most common method for synthesizing polymers with a carbon–carbon main chain backbone is vinyl polymerization, by which many industrially important polymers, including common plastics such as ...

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 ...

Yttrium-based catalysts can be used to stitch together two different lactone monomers in an alternating fashion to produce polyesters with well-defined primary structures. The ability to control the ...

This ultimate goal of this project is to develop advanced drug delivery systems, which combat diseases by effectively sending "targeted bombs" to disease sites. Project is Not Currently Available This ...

Even though many industrial plastics are recyclable, a significant proportion of the plastic waste is not recycled because of the energy demand and cost associated with the process. Chemically ...

Researchers create 'living' polymers that grow, degrow, and reprogram their properties after fabrication using reversible chemistry and light-activated catalysts. (Nanowerk Spotlight) A salamander can ...

The use of plastics materials has increased dramatically throughout the world over the past 50 years, and now stands at roughly 100 billion pounds. Commercial plastics are known as resins in North ...

For more than two decades, the Ihara research group has been focusing on the development of new methods for polymer syntheses using diazocarbonyl compounds as monomers. They found that diazoacetate ...
