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 ...

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 ...

Chemists craft molecule that self-assembles into flower-shaped crystalline patterns

02-Dec-2015

Designing new materials at the molecular level is a key goal of the U.S. government's Materials Genome Initiative, a project launched in 2011 to reduce the cost, and speed the creation, of these materials. As recipients of funds from the NSF's Designing Materials to Revolutionize and Engineer our ...

Revolutionary discovery leads to invention of new 'building blocks'

University of Akron polymer researchers create a new class of hybrid materials

27-Apr-2015

Polymer science will have to add a new giant molecule to its lexicon thanks to a cutting-edge discovery at The University of Akron. Taking a revolutionary "building blocks" approach, researchers have pioneered a way to create a new class of very large polymer molecules, called macromolecules, ...
