Intricate, curving 3D nanostructures for biological and materials applications


Twisting spires, rings within rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can grow from carbon nanotubes using a unique fabrication method. Such nanostructured shapes, which are difficult if not impossible to build ...


Listen up! U-M experiment records ultrafast chemical reaction with vibrational echoes


To watch a magician transform a vase of flowers into a rabbit, it's best to have a front-row seat. Likewise, for chemical transformations in solution, the best view belongs to the molecular spectators closest to the action. Those special molecules comprise the "first solvation shell," and ...


Mexico ‘dead zone’: impact of oil spill unclear


University of Michigan aquatic ecologist Donald Scavia and his colleagues say this year’s Gulf of Mexico “dead zone” is expected to be larger than average, continuing a decades-long trend that threatens the health of a $659 million fishery. The 2010 forecast, released today by the U.S. National ...

Light twists rigid structures in unexpected nanotech finding


In findings that took the experimenters three years to believe, University of Michigan engineers and their collaborators have demonstrated that light itself can twist ribbons of nanoparticles. The results are published in the current edition of Science. Matter readily bends and twists light. ...


Paper strips can quickly detect toxin in drinking water


A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. Engineers at the University of Michigan led the development of the new biosensor. The paper strips perform 28 times faster than the complicated method most commonly ...


Music is the engine of new U-M lab-on-a-chip device


Music, rather than electromechanical valves, can drive experimental samples through a lab-on-a-chip in a new system developed at the University of Michigan. This development could significantly simplify the process of conducting experiments in microfluidic devices. A lab-on-a-chip, or ...


New nanoporous material has highest surface area yet


University of Michigan researchers have developed a nanoporous material with a surface area significantly higher than that of any other porous material reported to date. "Surface area is an important, intrinsic property that can affect the behavior of materials in processes ranging from the ...


New research shows why metal alloys degrade


Metal alloys can fail unexpectedly in a wide range of applications - from jet engines to satellites to cell phones - and new research from the University of Michigan helps to explain why. Metal alloys are solids made from at least two different metallic elements. The elements are often mixed ...


Safer, easier system for remote explosive detection


Detecting roadside bombs may become easier, thanks to chemical sensors being developed at the University of Michigan. A team led by chemistry professor Theodore Goodson III has created materials that sniff out TNT and give off signals that can be detected remotely - from a moving Humvee, for ...


Dead on Target: Multifunctional nanoparticle platforms for targeting and imaging cancer cells


There has been much recent interest in how nanotechnology will impact the field of medicine. Unfortunately, a number of promising nanostructured systems have turned out to be extremely toxic to humans, thus precluding their use in clinical applications and dashing hopes of an early success for ...
