Siloxane Polymer Achieves Record Stretchiness

Chemists working at Pennsylvania-based materials supplier Gelest have created a siloxane polymer that is so stretchy, two yards of the material could extend across the length of a football field. Gelest’s manager of silicone R&D, Jonathan Goff, publicly unveiled the polymer Tuesday at the ACS national meeting in Boston during a session hosted by the… Read more »

Automated Flow Technique Makes Length- And Sequence-Specific Polymers

Traditional synthetic polymers contain a distribution of chain lengths and monomer sequences. For applications such as molecular electronics, however, scientists want to create polymers of a specific sequence and length—a difficult task. Frank A. Leibfarth, Jeremiah Johnson, and Timothy Jamison at MIT have now developed Flow-IEG (flow synthesis and iterative exponential growth), a semi-automated coupling… Read more »

Sunlight Coaxes Urban Grime To Release Smog Compound

A grimy film covers the streets, statues, and buildings in our cities. This dirty chemical soup, deposited from pollution and dust, could play a previously unknown role in urban air quality, according to research presented Monday at the American Chemical Society national meeting in Boston. Chemists report that, when hit with sunlight, urban grime may… Read more »

Porous Polymer Could Spot Traumatic Brain Injuries

The forces from an explosive blast or a head-on tackle can shake a person’s head, causing damage that might trigger long-term neurodegeneration. To help doctors determine whether a patient might suffer from this type of traumatic brain injury, materials scientists have developed a thin polymeric film that changes color when struck with forces similar to… Read more »
