In a leap forward in this field, ...

Mastering metastable matter

13-Mar-2018 - Be it snow on a slope that can sit there for days before being sent descending by an overambitious skier or bonds in macromolecules that change dramatically upon appropriate activation -- systems that reside for extended periods of times in one state before switching rapidly to another, ...

The Making of Biorelevant Nanomaterials

05-Jan-2018 - The interactions of biological macromolecules such as nucleic acids, proteins, and polysaccharide–protein conjugates can be mimicked by artificial polyelectrolytes. Such synthetic polyionic complexes are expected to serve as novel platforms to stabilize and deliver drugs, proteins, or nucleic ...

Naked molecules dancing in liquid become visible

Visualizing polymers moving inside tiny graphene pockets

25-Sep-2017 - Moving, vibrating and leaping molecules make up our world. However, capturing their movement is not an easy task. IBS scientists at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS), were able to see the movement of molecules stored inside a graphene pocket ...

One-nanometer trimetallic alloy particles created

02-Aug-2017 - The principal component of petroleum and natural gas are hydrocarbons and their mixtures, and are indispensable as resources supporting modern infrastructure as raw materials for the petrochemical industry. A technique which has been conventionally used to create beneficial chemical products from ...

Plastic made of sugar and carbon dioxide

15-Jun-2017 - Some biodegradable plastics could in the future be made using sugar and carbon dioxide, replacing unsustainable plastics made from crude oil, following research by scientists from the Centre for Sustainable Chemical Technologies (CSCT) at the University of Bath. Polycarbonate is used to make ...

Light to design precision polymers

Light is used to specifically design defined molecule chains

02-Dec-2016 - Chemists of Karlsruhe Institute of Technology (KIT) 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, i.e. monomers, along polymer chains of standard ...
