Those new bio-based tires — already available as prototypes— are the topic of an article in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.
C&EN Senior Business Editor Melody M. Bomgardner explains that tight supplies and high prices for the natural rubber and synthetic rubber used to make tires — almost 1 billion annually worldwide —are fostering the drive toward renewable, sustainable sources for raw materials.
Petroleum, for instance, is the traditional source for raw materials needed to make tires, with a single tire requiring almost 7 gallons of oil. But changes in oil-refining practices have reduced supplies of those raw materials.
The article describes how companies like Goodyear and Michelin have teamed up with biotechnology firms to genetically engineer microbes that produce the key raw materials for rubber from sugar.
Goodyear’s partner Genencor, for example, is making microbes that mimic rubber trees’ natural processes to make latex rubber. Goodyear has already produced prototype tires with rubber made from sugar. Bomgardner explains that companies hope sugar will buffer them against future shortages of natural and synthetic ingredients, with “sweet” tires making a debut within 3-5 years.“Making Rubber from Renewables”

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
