Primeval Reaction Pathways

Some reactions in the reverse Krebs cycle can also be run under meteorite catalysis

25-Nov-2022 - Naturally occurring chemical reactions may have evolved into the biochemical processes we know today. A team of researchers has now discovered that a reaction sequence from the so-called reverse Krebs cycle—a fundamental biochemical process—can also take place without enzymes. The team writes in ...

Motor And Energy Store In One

Physicists reinvent the wheel with the help of a polymer fibre

07-May-2018 - Physicists and material scientists have succeeded in constructing a motor and an energy storage device from one single component. They used an elastic polymer fibre closed into a ring that was made to rotate on application of an external energy supply. The researchers from the universities in ...

BASF and three top European universities team up on functional materials research

Goal: innovation in multi-materials and systems

09-Dec-2011 - BASF SE has set up a research initiative called Joint Research Network on Advanced Materials and Systems (JONAS) in collaboration with the universities of Strasbourg, France; Freiburg, Germany, and ETH Zurich, Switzerland. The aim is to work jointly to strengthen the scientific base and ...

Micromuscles: Micrometer-Sized Actuators from Liquid-crystal Elastomers

12-Aug-2009 - To move your arm or leg, certain muscles need to change shape, to either lengthen or contract. Now scientists have made liquid-crystalline particles that can change shape in a similar way, but which are only micrometers across. Professor Rudolf Zentel and his colleagues at the Universities of ...

Copper(I) interlocks rings and rods

11-Mar-2009 - Scientists in France have synthesised highly functional [4]pseudorotaxanes utilising the gathering and threading effect of copper(I). Jean-Pierre Sauvage, Jean-Paul Collin, Valérie Heitz and colleagues from the University of Strasbourg, in France, have prepared a highly functional interlocking ...
