Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published in Physical Review X, can rotate the polarization of an arbitrarily polarized incident wave without changing its axial ratio. Metasurfaces are artificial sheet materials textured at a sub-wavelength scale in order to produce tailored electromagnetic responses. In recent ...

Arrays of anchored fibers are widely used in nature and consumer products such as sensors, thermal insulators, and adhesives, among other applications. As reported in a recent issue of Science, a collaboration led by researchers from the University of Michigan and Cornell University has introduced a potentially scalable approach to synthesizing nanometer-scale polymer fiber arrays. This process offers unprecedented control over the fiber properties. Polymer nanofibers with (a) countercloc...

              At least 15 unique phases of solid nitrogen are known, including twelve molecular phases, two non-molecular phases and one amorphous state. The elusive high-temperature, high-pressure phase called ι-N2 was discovered in 2002 by a Carnegie Institution-led team of researchers but its structure was unknown until now. “Our study demonstrates that the appearance of complex structures under pressure is not limited only to ...

A team led by Nicholas Melosh, an associate professor of materials science and engineering, first began testing nanostraws about five years ago using relatively tough cell lines derived from cancers, mouse cells and other sources. Now, Melosh and colleagues have shown the technique works in human cells as well, a result that could speed up medical and biological research and could one day improve gene therapy for diseases of the eyes, immune system or cancers. "What you're seeing is a huge pu...

  The “International Functional Nanomaterials and Nanodevice Conference 2018” was held in Vienna, Austia, from 3-th to 5-th September 2018. It managed to gather prominent participants working in the field of nanomaterials. The conference covered fields like energy conversion and storage, synthesis and characterization of nanomaterials, catalysis for clean energy and chemical production, and nanobiotechnologies. Nanomat2018 was attended by both scientists and industry and provided the ...

The "International Functional Nanomaterials and Nanodevice Conference 2017" was held in Budapest, Hungary, from 24 to 27 September 2017. It managed to gather over 100+ prominent participants working in the field of nanomaterials. There were at least 20 Invited Speakers with an h-index above 25 while the top 5 speakers had an h-index above 50. The conference covered fields like energy conversion and storage, synthesis and characterization of nanomaterials, catalysis for clean energy and chemica...
