Columbia researchers published a study today in Nature Nanotechnology that is the first to reproducibly demonstrate current blockade—the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time—using atomically precise molecular clusters at room temperature. The study shows that single molecules can function as reproducible circuit elements such as transistors or diodes that can easily operate at room temperature.
A new study led by Columbia Engineering Prof. Michael P. Burke has identified the significance of a new class of chemical reactions—previously ignored—involving three molecules that each participate in the breaking and forming of chemical bonds. The reaction of three different molecules is enabled by an “ephemeral collision complex,” formed from the collision of two molecules, which lives long enough to collide with a third molecule.

They report their findings this week in The Journal of Chemical Physics.
Since the seminal work of Paul Flory, researchers have developed various formulas for calculating distance between the ends of a curved polymer. However, these formulas have typically failed to consider the stretchiness of the molecule. In a new study, published this week in The Journal of Chemical Physics, scientists have derived a formula to determine the end-to-end distance of a semiflexible polymer, including DNA or RNA, while taking into account how much the polymer stretches.
Each cell in the body is made up of a number of tiny sealed membranous subunits called organelles, and they send things like lipids back and forth to allow the cell to function. A process called membrane tethering is responsible for bridging the gap between organelles, and now, Texas A&M researchers have discovered a way to manipulate this tethering. The study was the cover story in the journal Chemical Science.
