Green Chemistry: Sustainable p-xylene production

Green, sustainable and biodegradable polymers

18-Sep-2020

Lemonade, juice and mineral water often come in PET bottles. While these are practical and functional, their production is complex and not necessarily sustainable. The starting material for terephthalic acid, which is used to produce saturated polyesters such as PET (Polyethylene terephthalate), ...

Put into the right light - Reproducible and sustainable coupling reactions

Improved methods for coupling reactions with light by targeted control of the catalyst activity

09-Jul-2020

A team of researchers reports in the journal Nature Catalysis that sustainable carbon-nitrogen cross-couplings can be performed using simple nickel salts, carbon nitrides and light. The chemists study the use of cost-effective and reproducible semiconductors as photocatalysts in coupling ...

Largest Synthetic Polysaccharide Assembled

Linear 100-mer polysaccharide within 188 hours

05-May-2020

Chemists at the Max Planck Institute of Colloids and Interfaces (Potsdam, Germany) have set a milestone by preparing the two largest carbohydrates ever assembled. Using an Automated Glycan Assembly (AGA) instrument originally developed at the institute they prepared a linear 100-mer and achieved ...

A chemical factory for all cases

Radial synthesis breaks new ground for chemical research and production

23-Mar-2020

In the future, bottlenecks in the supply of medicines could be more easily eliminated. An automated machine for radial synthesis developed by chemists at the Max Planck Institute of Colloids and Interfaces will enable the flexible production of medical agents and other chemical products. The ...

New material for chemistry text books

Calcium carbonate forms a previously unknown aqueous crystal structure

06-Mar-2019

Even the well-known can sometimes surprise. Calcium carbonate (CaCO3), also known colloquially as lime or chalk, is a mineral that has already been thoroughly analysed by chemists. But chemistry books, in which it is listed as occurring in five different crystal structures, now need to be ...

Stiff fibres spun from slime

Nanoparticles from the secretion of velvet worms form polymer fibres that can be recycled in water

18-Oct-2017

Nature is an excellent teacher – even for material scientists. Researchers, including scientists at the Max Planck Institute of Colloids and Interfaces, have now observed a remarkable mechanism by which polymer materials are formed. In order to capture prey, velvet worms shoot out a sticky ...

Nanostructures: customized carbon

A new synthesis method produces novel nanostructures from carbon

17-Apr-2015

They are tiny and comprise spherical, sheet-like or fibrous particles. And they consist chiefly of the chemical element carbon. The talk here is about unusual carbon nanostructures that scientists at the Max Planck Institute of Colloids and Interfaces in Potsdam-Golm are now producing with a ...

An assembly line for medications

Efavirenz can now be produced more cost efficiently and sustainable utilizing continuous flow chemistry.

25-Feb-2015

Researchers at the Max Planck Institute of Colloids and Interfaces (MPICI) and the Freie Universität Berlin have succeeded in developing better methods of producing APIs (active pharmaceutical ingredients). As a result, Efavirenz, one of the preferred agents for treating HIV in combination ...

A spoonful of sugar in silver nanoparticles to regulate their toxicity

23-Jan-2015

The use of colloidal silver to treat illnesses has become more popular in recent years, but its ingestion, prohibited in countries like the US, can be harmful to health. Scientists from the Max Planck Institute in Germany have now confirmed that silver nanoparticles are significantly toxic when ...
