Application of focused ion beam technology for photonic nanostructures

Ay F., Gadgil V.J., Geskus D., Aravazhi S., Wörhoff K., Pollnau M., MESA+ institute of nanotechnology, University of Twente, NL

Al2O3 and KY(WO4)2 are promising materials for photonic applications with excellent optical properties and of interest for obtaining on chip resonator structures. However, there is no method available to fabricate these structures except FIB technology. [...]

Patterning Technology for Nanomanufacturing

Smith H.I., Walsh M., Zhang F., Hourihan G., Ferrera J., Jaspan M., LumArray, US

We describe a new approach to patterning that circumvents the limitations of techniques that were developed for the semiconductor industry. The new approach, zone-plate-array lithograhy (ZPAL)will enable an expansion of applications of nanoscale science and [...]

Nanoscale Force Induced Size-selective Separation and Self-assembly of Metal Nanoparticles

Zheng Y., Monash University, AU

A simple and versatile nanoscale force induced precipitation approach for the separation of gold nanoparticles (AuNPs) was developed. The AuNPs show sharp size-dependent colloidal stability thresholds as a function of salt concentration. Upon separation, the [...]

New technology for metal nanorods formation

Balucani M., University of Rome “La Sapienza”, IT

Nowadays, Novack et al. proposed a new and efficient approach for producing electricity from sun, using nanoantenna (nantenna) electromagnetic collectors with an efficiencies approaching 84%. The major technical challenge to be solved is the development [...]

NanoFab: Manufacturing & Instrumentation

Development of Precision Stage with Magnified Displacement System

Kim J.G., Choi S.C., Lee D.W., Pusan National University, KR

In this study, a new precision stage was developed using self-lever-mechanism to magnify its moving displacement optically. The developed precision stage was constructed as a position-sensitive photodiode (PSPD), a laser diode (LD), and a hinge-connected [...]

Development of Nitrogen modified TiO2 and activated carbon fiber composites in single step

Tsai C-Y, Hsi H-C, Fan K.-S., National Taipei University of Technology, TW

The aim of this study is to develop visible-light photocatalyst nanopowders by N2 modified TiO2 matrix via gas-phase evaporation condensation with thermal plasma as a heating source. The formed visible-light TiO2 nanopowders are subsequently doped [...]

VDK 4000 Direct Write System: A new approach to direct write technology

Theodore M., Fielding J., Royer J., Kalanovic V., Nirilovic J., Sears J., AFRL, US

VDK 4000 is a Flexible Robotic Environment (FRE) direct write system. The idea behind Flexible Robotic Environment (FRE) concept is building a robotic modular system around an application instead of having an application fit within [...]

Deposition of Interwoven Fibrous Nanostructure using Ultrafast Laser Ablation in Ambient Condition

Tavangar A., Tan B., Venkatakrishan K., Ryerson University, CA

In this paper, a new method for site-specific deposition of fibrous nanostructure is demonstrated using laser induced reverse transfer (LIRT). The LIRT method makes it achievable to generate and deposit fibrous nanostructure of a wide [...]

Fabrication of biodegradable zein films by using soft lithography

Altunakar B., Kokini J.L., University of Illinois at Urbana-Champaign, US

Microfluidic components are widely used in the design of both bioanalytical and diagnostic microdevices. The miniaturized sample volumes together with modifications of the surface chemistry and localization of molecules within microfluid channels has opened many [...]
