Researchers find unexpected magnetic effect

Combining two thin-film materials yields surprising room-temperature magnetism. David L. Chandler | MIT News Office May 9, 2016 A new and unexpected magnetic effect has taken researchers by surprise, and could open up a new pathway to advanced electronic devices and even robust quantum computer architecture. The finding is based on a family of materials […]

Ultrafast switching of tunable infrared plasmons in indium tin oxide nanorod arrays with large absolute amplitude

  All-optical control of plasmons can enable optical switches with high speeds, small footprints and high on/off ratios. Here Guo et al., demonstrate ultrafast plasmon modulation in the near-infrared (NIR) to mid-infrared (MIR) range by intraband pumping of indium tin oxide nanorod arrays (ITO-NRAs). They observe redshifts of localized surface plasmon resonances arising from a change […]

Fabrication and characterization of nonenzymatic glucose sensor based on bimetallic hollow Ag/Pt nanoparticles prepared by galvanic replacement reaction

Fig.1. Schematic of the formation of BH-Ag/Pt NPs at different stages of galvanic replacement process Daqian Ma et al., successfully fabricated a non-enzymatic glucose sensor by immobilization of bimetallic hollow Ag/Pt nanoparticles (BH-Ag/Pt NPs) using the galvanic replacement reaction onto the surface of the pretreated pure Au electrode. The morphology and composition of the BH-Ag/Pt […]

Wide-angle, broadband, and highly efficient holography

Jacob Scheuer, Yuval Yifat, Michal Eitan-Wiener, Zeev Iluz, Yael Hanein and Amir Boag Coupled dipole-patch nano-antenna cells are used in a new approach to impose an arbitrary phase profile on reflected light. 28 January 2016, SPIE Newsroom. DOI: 10.1117/2.1201512.006252 Computer-generated holography is a widely used technology for various applications, e.g., from authentication and optical data storage, to […]

Plasmonic optical tweezers: A long arm and a tight grip

Plasmonic optical tweezers: A long arm and a tight grip

  By taking advantage of the thermal gradient that is generated in plasmonic systems and by using an a.c. field, plasmonic tweezers can have a large radius of action and can trap and manipulate single nano-objects.   To have access to this paper, please visit: http://www.nature.com/nnano/journal/v11/n1/full/nnano.2015.253.html

Plasmons Enhance Detection of Wavefront Aberrations

Plasmons Enhance Detection of Wavefront Aberrations

DUBLIN, Dec. 8, 2015 — A sensor that exploits plasmonics to gauge nanoscale distortions in lightwaves could yield more powerful tools for metrology and chemical sensing, as well as sharper microscopes. The method detects wavefront aberrations indirectly by measuring changes in the reflectivity of gold films. It may be the first to use plasmons to […]
