Theory and experiments to understand a contact between two filaments
Mechanical engineers and mathematicians at EPFL have joined forces to gain a better understanding of the geometry and mechanics of two filaments in contact – as in the cases of knots and woven fabrics.
Pedro Reis, head of EPFL’s Flexible Structures Laboratory, and John Maddocks, head of EPFL’s Laboratory for Computation and Visualization in Mathematics and Mechanics, have something in common: a fascination with ropes and knots. Reis, an engineer, is an avid rock climber while Maddocks, a mathematician, has a passion for sailing. But their mutual interest in knots is not restricted to their hobbies, as knots are used in a variety of applications – take surgical sutures, for example. And although knots have been part of our daily lives since the dawn of time, their mechanics are still poorly understood.
New technique helps image biological samples at the microscopic level
Researchers have developed a spectroscopic microscope to enable optical measurements of molecular conformations and orientations in biological samples. The novel measurement technique allows researchers to image biological samples at the microscopic level more quickly and accurately.
The new instrument is based on the discrete frequency infrared spectroscopic imaging technique developed by researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign.
This project is about bringing the study of molecular chirality into the microscopic domain.

Molecular chirality refers to the spatial orientation of atoms in molecules or multimolecule assemblies. In biological systems, one molecule may elicit a cellular response, while its mirror image could be inactive or even toxic. While vib
