First programmable photocatalyst developed

With smart materials toward more sustainable chemistry

03-Sep-2021

Researchers at the Max Planck Institute of Colloids and Interfaces have developed a sustainable and "smart photocatalyst". The special feature: as a so-called smart material, it can distinguish between the colors of light (blue, red and green) and, in response, enables a specific chemical ...

Nanomaterials with laser printing

New and environmentally friendly method for synthesizing materials

02-Jun-2021

In the journal Nature Communications, an interdisciplinary team from the Max Planck Institute of Colloids and Interfaces presents for the first time a laser-driven technology that enables them to create nanoparticles such as copper, cobalt and nickel oxides. At the usual printing speed, ...

In milliseconds from polluted to clear water

New discoveries in the field of nanoscience

19-May-2021

Researchers at the Max Planck Institute of Colloids and Interfaces developed a membrane that is composed of a bundle of nanometer-sized tubes. They used it as a nanoreactor to convert water marked with methylene blue into clear water in milliseconds using sunlight as a driver. ‘Running reactions ...

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 ...
