“…Then, they adsorbed on the nucleophilic groups in polymer chains and reduced to the metallic Pd nanoparticles. In this work, Pd(acac)2 was vaporized at 180°C in vacuum condition and the vapor penetrated into the PAN, however it was very dense polymer so that the vaporized Pd(acac) 2 could not penetrate deeply into PAN fiber. Therefore almost all Pd nanoparticles were positioned on the surface area of PAN fiber.…”

Abstract. Micro-sized Ni-P alloy tube was fabricated by electroless plating on polyacrylonitrile (PAN) fiber with μm sized diameter as a template. PAN fiber was loaded with Pd nanoparticles using a drying process and Ni-P alloy was deposited on the Pd nanoparticles loaded on PAN surface in an electroless Ni plating solution, and finally PAN fiber was thermally decomposed resulting micro-sized Ni-P alloy tube. The tube was observed by scanning electron microscopy (SEM) and elemental analysis via energy dispersive spectroscopy (EDS) analysis confirmed that the micro-sized tube was composited with Ni: P = 94.3 : 5.7 atomic %.

The fountain pen approach, as a means for transferring materials to substrates, has shown numerous incarnations in recent years for creating 2D micro/nanopatterns and even generating 3D free-form nanostructures using a variety of material "inks". While the idea of filled reservoirs used to deliver material to a substrate via a capillary remains unchanged since antiquity, the advent of precise micromanipulation systems and functional material "inks" allows the extension of this mechanism to more high-tech applications. Herein, the recent growth in meniscus guided fountain pen approaches for benchtop micro/nanofabrication, which has occurred in the last decade, is discussed. Particular attention is given to the theory, equipment, and experimentation encompassing this unique direct writing approach. A detailed exploration of the diverse ink systems and functional device applications borne from this strategy is put forth to reveal its rapid expansion to a broad range of scientific and engineering disciplines. As such, this informative review is provided for researchers considering adoption of this recent advancement of a familiar technology.

The purpose of this research was to develop a new micro-anode-guided electroplating (MAGE) system equipped by an image-guided positioning controller, to fabricate two-dimensional microstructures. From real-time image, the relative positions of the micro-anode and the microstructures tip can be located and maintained. When the relative position is adjusted, the deposition direction of the microstructures can be controllable and microstructures with different geometries can be fabricated.During past decades, the fabrications of 3D microstructures and nanostructures have been attracting attention because of their applications in biosensors, gas sensors, thermal couples, and 3D integrated chips. Many processes have been proposed to produce 3D micro-and nanostructures, such as Lithographie Galvanoformung Abformung (LIGA), 1 localized electrochemical deposition (LECD), 2 mask projection micro-stereo lithography, 3 track-etch method, and laser-assisted chemical vapor deposition (LCVD). 4 Among these techniques, LECD has the advantages of being an inexpensive, mask-less, low-power, and easy-to-design technique. 5-12 Furthermore, LECD can be applied to multiple materials such as metals, metal alloys, piezoelectric material, conducting polymers, and semiconductors. 13 New methods have been proposed to improve the performance of LECD; these include micro-anode-guided electroplating (MAGE), 14 deposition-detection-withdrawal (DDW) control method, 15 and realtime image-guided micro-anode electroplating system. MAGE has demonstrated that the micro-anode can be controlled to move in either continuous or intermittent mode to guide the progress of Nielectroplating; 14 hence, it influences the surface morphology of the electroplated microstructures. Although the resulting microstructures are less porous, their surface is rough and nodular. To improve the surface quality of microstructures by employing the MAGE process, C.S. Lin proposed a DDW control method, 15 which could prevent the possible contact between the microstructures and the micro-anode. However, the resulting surfaces are not uniform because the deposition rate is not constant as it is affected by electric field that is applied on surface of the microstructures. 16 Moreover, the variation of the electric field owing to the variation in the gap between the anode and microstructure cannot be controlled by employing the MAGE process or DDW control method. To address all these problems, a MAGE system with real-time image processing was proposed to create a steady electric field on the microstructure surface proposed. 17 This system stabilizes the distance between the anode and the microstructure on the basis of measurements based on from real-time imaging, ensuring that the formed column structures are smooth with no pores, uniform, and straight. Moreover, the diameter of the microstructure can be controlled by adjusting different parameters, such as applied voltage and the distance between the anode and the microstructure. 18 Most previous studies 13-21 mainly focused on...
