This structure composed of multiple holes array by filling it with nonlinear medium combines the characteristics of selectable wavelength, enhanced transmission, polarization separation and output control by the intensity of incident light. This result is useful for integrated optical circuits and on-chip optical interconnects.
Scientists have developed a new technique to enhance stroke treatment that uses magnetically controlled nanomotors to rapidly transport a clot-busting drug to potentially life-threatening blockages in blood vessels.
Wissenschaftler haben ein neues Verfahren entwickelt, um die Reibungskräfte in Schmierstoffen auf molekularer Ebene zu messen. Dabei konnten sie den schichtartigen molekularen Aufbau des eigentlich flüssigen Schmierstoffs deutlicher sehen als mit bislang gängigen Methoden.
Super-critical fluid electro-deposition (SCFED) integrates well proven technologies to offer a disruptive, scalable approach to building metal and semiconductor nanostructures an order of magnitude smaller than is achievable using photolithography.
GE leads Power Electronics Manufacturing Consortium to develop next generation of materials and processes used on wide band gap semiconductors in partnership with SUNY College of Nanoscale Science and Engineering.
In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers from Lawrence Berkeley National Lab to design an entirely new kind of resist. Results could be easily incorporated by companies that make resist, and find their way into manufacturing lines as early as 2017.
A three-dimensional porous nanostructure would have a balance of strength, toughness and ability to transfer heat that could benefit nanoelectronics, gas storage and composite materials that perform multiple functions.
Using a newly developed, ultrafast femtosecond infrared light source, chemists have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules - the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.
Thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future. A new study shows how porous substances can act as thermoelectric materials - pointing the way for engineering the use of such materials in thermoelectric devices of the future.
This method is based on the reactivity of a group of molecules named arynes, which can act as 'molecular glue' to paste graphene fragments together. The clover-shaped nanographenes obtained in this research were deposited on ultrathin insulating films, and imaged with atomic resolution by atomic force microscopy.
Researchers succeeded in growing thin film crystals consisting of highly oriented crystal grains, which were as large as a few micrometers or more, by coating a glass substrate with oxide sheets of about one nanometer in thickness, called oxide nanosheets, and using these nanocrystals as seed crystals in solid phase crystallization.
