Researchers have demonstrated that the detailed shape of the electric field inside a short light pulse can be used to control the motion of electrons involved in chemical bonding and to change the outcome of a simple chemical reaction.
Researchers have found a way to use the electric-field process to make nanofibers in a direct, continuous and controllable manner. The new technique, known as near-field electrospinning, offers the possibility of producing out of nanofibers new, specialized materials with organized patterns that can be used for such applications as wound dressings, filtrations and bio-scaffolds.
Tiny materials may bring about large-scale advances in a future hydrogen economy, Institute Professor Mildred S. Dresselhaus told audiences Wednesday, April 5, at MIT and at the Technion Israel Institute of Technology.
A new environmental chamber constructed by Argonne National Laboratory allows researchers to watch materials as they grow step-by-step while interacting in elevated-temperature, reactive-gas environments.
Researchers have developed a technique that allows them to attach molecules to just a few specific nanotubes within an array of thousands of nanotubes. This new method could speed the development of nanosensor arrays capable of detecting multiple cancer markers in human tissue or blood samples.
The National Institute of Advanced Industrial Science and Technology (AIST) and Toyama University in Japan have jointly developed a nano-mechanical fabrication system working in a scanning electron microscope (SEM), and thereby succeeded in real-time imaging of the nano-scale cutting process for a single crystal of silicon.
