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”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
