Giant network links all known compounds and reactions to create chemical Google on steroids Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids. This "immortal chemist" will never retire and take away its knowledge but instead will continue to learn, grow and share. A decade in the making, the software optimizes syntheses of drug molecules and other important compounds, combines long...

Squeezing polymers produces chemical energy but raises doubts about implant safety A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA damage and cancer in the human body. In a new study, Northwestern University scientists turned to squeezed...

When will artificial molecular machines start working for us? Physicist Richard Feynman in his famous 1959 talk, "Plenty of Room at the Bottom," described the precise control at the atomic level promised by molecular machines of the future. More than 50 years later, synthetic molecular switches are a dime a dozen, but synthetically designed molecular machines are few and far between. Northwestern University chemists recently teamed up with a University of Maine physicist to explore the...

Scientists develop new nanomaterial that ℠steers´ current in multiple dimensions Scientists at Northwestern University have developed a new nanomaterial that can "steer" electrical currents. The development could lead to a computer that can simply reconfigure its internal wiring and become an entirely different device, based on changing needs. As electronic devices are built smaller and smaller, the materials from which the circuits are constructed begin to lose their...
