The research funded by this grant has enabled  to develop a conceptually new approach to colloidal self-assembly that borrows no material from biology and entirely relies on the innate charge that any colloidal particle develops in water.

Searching for new materials and phenomena to enable voltage control of magnetism and magnetic properties holds compelling interest for the development of low-power non-volatile memory devices. Here, we report on a non-volatile ON/OFF voltage control of magnetism in thin films of an oxide, SrCo1-xFexO3-δ (SCFO).

MRSEC investigators rediscovered DFDT and found that amorphous and crystalline forms of DFDT and a mono-fluorinated chiral congener, MFDT were more active against Anopheles and Aedes mosquitoes, the former the disease vector for malaria and the latter for Zika, yellow fever, dengue, and chikungunya.

NYU-MRSEC pursues its partnership with NYU-CSTEP (Collegiate Science and Technology Entry Program). The Center was invited to give a guest lecture as part of the NYU-CSTEP Research Initiative. 

A crystal is defined by the regular and periodic ordering of the atoms, molecules, or particles that compose them.  If bent or strained, this order and regularity is disturbed, and defects appear that relieve some of the applied stress.

Experiments (top) showing near zero-net magnetization of MnAu2Al following plastic deformation and simulations (bottom) of low energy displacive pathways enabled by local spin orderings.

A single parent diblock copolymer can be purified by automated chromatography to give libraries of well-defined, low dispersity block copolymers on multi-gram scale.

 Researchers at the Soft Materials Research Center of the University of Colorado have made hybrid bio-semiconductor nano-necklaces consisting of strings of nanometer size quantum dots (QDs) tethered by nano-length DNA chains.  When the necklaces are connected between electrodes and illuminated, the alignment of the energetic states of the QDs and DNA

A collaboration (Wells, Shenoy) in IRG 2 studied the mechanisms of mechanical plasticity in collagen networks resulting from contractile forces produced by cellular aggregates placed within them. The Wells group used fibroblast spheroids seeded atop collagen gels to study the plasticity of collagen fiber networks due to cell-induced forces. Second harmonic generation imaging and spectral analysis enabled quantification of the alignment of fibers between a pair of contractile cell clusters.

Current TEM cameras acquire images in a few milliseconds. The new camera will ultimately acquire images in just 8 microseconds, which will enable researchers to study fast processes in materials like atoms rearranging in a flowing liquid and to probe the smallest structures in materials.
