First principles modeling demonstrates that the efficiency of Multi-Exciton Generation (MEG) increases as quantum dot size decreases resolving a major controversy. The results were highly visible.
Polymer gels undergoing a self-oscillating chemical reaction have been previously shown to pulsate autonomously while exhibiting periodic color changes. Van Vliet and Balazs have now demonstrated that a non-oscillating, quiescent gel can be “resuscitated” by applying mechanical pressure to the material. By varying the conditions of the reaction, the amplitude and
MRSEC researchers have developed the materials necessary to embed GHz speed electronic photodetectors into micron diameter channels in optical fibers.
An international team studying the motion of both bacteria and similar-sized artificial catalytic nanomotors has found that they transfer momentum to their surroundings in a similar way, despite their very different propulsion mechanisms.
Ferroelectric ferromagnets are a holy grail of materials research, since they would enable electrically switchable magnetism with diverse potential applications in information technology, sensing and new “e
MRSEC scientists and collaborators have shown [1] that the localized buckling of a compressed thin sheet, important for molecular interfaces, [2] has the same mathematical origin
Luping Yu, Dmitri Talapin and collaborators from the University of Chicago MRSEC are working to develop highly efficient bulk heterojunction organic solar cells. They have recently
Highly-symmetrized MnAu nanoalloys may possess high magnetic moments for potential application. The magnetic properties of MnAu nanoclusters exhibit strong dependence on the cluster sizes and morphologies.
