Development of Precision Stage with Magnified Displacement System
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
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
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
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
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 [...]

GaN has relatively high refractive index and results in low light extraction efficiency in photonics applications. A novel way to combine the various methods to enhace the efficiency is to construct a pyramid array on [...]
Alkoxide-based precursors for direct drawing of metal oxide micro- and nanofibres
Metal oxide micro- and nanofibre materials are crucial in numerous technical solutions like textiles, filter mattes, optical cables, thermal insulators, reinforcing components, etc. However, complications to prepare these materials in desired shape often limit their [...]
In-situ Growth of Gold Nanoparticles Conductive Layer on Plastic Film as an Integrated Lead Ions Sensor
In this work, an in-situ chemical growth method was reported for grafting patterned gold nanoparticles (GNPs) conductive layers on polyethylene terephthalate (PET) substrates. This in-situ grown gold nanoparticle film could be used as a sensing [...]
