Researchers from North Carolina State University and the Chinese Academy of Sciences have created an efficient, semi-printed plastic...
In (a) an originally obtained picture of a one-dimensional atomic chain is shown. The thick horizontal lines illustrate the barrier between different chains. In each chain, an atom appearing on the upper side of the thin dashed horizontal line...

In a discovery that could have profound implications for future energy policy, Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells by using...
The nanofibers we produced are about 200 times thinner than cotton fibers. (a) Commercial sanitary napkins with fiber diameter ~30-40 micrometers; (b) Electrospun nanofiber-based prototype with fiber diameter ~ 200 nm. (Source: Yadav, Shital et al, Applied Materials Today,...
University of Vermont doctoral student Morgan Cousins holds up a sample of a solution of strange rotor molecules made from boron-based dye. Led by UVM chemistry professor Matt Liptak (on left), she was part of a team that tested...
The results could pave the way to the cleaner production of methanol, an important industrial feedstock and potential green fuel.
A team led by chemists at Stanford University has unraveled a longstanding mystery that brings them one step closer to...
Multiferroics -- materials that exhibit both magnetic and electric order -- are of interest for next-generation computing but difficult to create because the conditions conducive to each of those states are usually mutually exclusive. And in most multiferroics found...
A nanoparticle-based drug delivery system that can sense and respond to different conditions in the body, as well as to an externally applied magnetic field, could enhance doctors' ability to target drugs to specific sites of disease.
Singapore's Agency for...
Shaped with ultrasound: Max Planck researchers from Stuttgart transmit ultrasonic waves through a bath of water and microparticles. In doing so, they model the profile of the sound pressure with a hologram in such manner that the particles are...
