Understanding microtubule dynamics has important implications for establishing nanometer level machines. Object tracking is one of the important issues necessary to elucidate the dynamics of microtubule from video data. In microtubule gliding assays, object tracking becomes non-trivial due to the occurrences of compound objects and high density objects. In this work, we investigate microtubule dynamics focusing on its morphological information, and we developed easy and useful workflow with compound segmentation technique and probabilistic data association filter. Using this workflow, multi-crossing microtubules can be decomposed, and be tracked correctly.

In this work, we used different pyrenes derivatives with a carboxylic acid group to modify the surface of carbon nanotubes (CNTs). This non-covalent method of functionalization can improve the dispersion of CNTs in organic solvent without damaging the desired properties of CNTs. Thin films of CNTs functionalized with pyrene derivatives were deposited onto the glass substrate, which in prior, was treated by 3-aminopropyltri-ethoxysilane (APTES). N,N'-Diisopropylcarbodiimide (DIC), a cross-linker, facilitates the reaction of carboxylic acid group on CNTs with the amino group of APTES. We found that the introduction of DIC resulted in increased robustness of CNTs thin films on the glass substrate. Increase of interfacial adhesion can be attributed to the covalent bond formed during this process. We studied the effect of concentration of APTES and DIC on film adherence by subjecting them to waterjet. Our results show that the CNTs thin films were robust and smooth. The morphology analysis by Scanning Electron Microscopy and Atomic Force Microscopy techniques reveal that the surface functionalized CNTs thin films on glass substrates were smooth and the roughness was about 21.3 nm for the APTES-treated sample. We obtained relatively smooth CNTs thin films which possess high interfacial adhesion with the glass substrate due to covalent bond formed between amino group and carboxylic acid group.

Redox flow battery is one of secondary batteries, which is a kind of a fuel cell because it also utilizes active material supplied externally. It has been paid attention since it has been considered as a solution for large-scale energy storage. We miniaturized the cell of Zn/Br redox flow battery as an energy source for a sensor node of wireless sensor network systems. In this paper, we report the fabrication and the experimental results for performance characteristics of the miniaturized Zn/Br redox flow battery cell. Especially, we investigated the electrode material influence on its characteristics utilizing three kinds of carbon materials.

Generally, the 3ω method for the measurement of fluid thermal properties is based on an approximate solution to heat conduction model assuming vanishing heater-thickness, no dielectric layer and infinite heater-length. In this study, a novel three-dimensional model and partial differential equations of the dimensionless heating conduction in frequency domain were established, which took into account the finite thicknesses of the heater and dielectric layer as well as a finite heater length to investigate thermal conductivity and diffusivity of fluid. Through the numerical studies, it was found that we could reduce the ratio of thickness to width of heater or the thickness and thermal conductivity of the dielectric layer to minimize discrepancy between the numerical results and the approximate solutions. Additionally, the edge effects of a finite heater length can be ignored at low measurement frequencies and high ratio of length to width of the heater.

In the advancement of printed electronics industry, the development of screen-printing techniques in order to form finer wires with a higher aspect ratio is an important task. To this end, we evaluate electrical characteristics of conductive wires formed by the screen-printing process combined with an imprinting technique. We show that fine and high-aspect-ratio wires are realized by the capillary force of parallel-walled structures (PWSs) on polymer films. A printed wire with a line width of 8.4 μm and an aspect ratio of 7.9 is obtained. The printed wires act as conductive wires according to the electrical evaluation. Moreover, the electric resistances of the wires formed by the proposed process keep low values compared with the increasing trend of resistance by the conventional process. At the height of PWS from 40 to 80 μm, the average resistances are gradually decreased from 228 to 87 kΩ/mm with an increase of the height. When the height is increased from 80 to 140 μm, on the other hand, since the decrease of the resistance cannot be observed, we confirm that there is a limit to form a high-aspect-ratio wire using the screen-printing condition. The printing condition needs to be further improved in future to produce an effect on the proposed screen-printing process.

Aim is to show how to make neodymium iron alloys available for MEMS process by electroplating used for permanent magnetic material. Because of the low electrochemical potential of neodymium, three different deposition methods were investigated: Electroplating from aqueous solvent, from non-aqueous solvent and molecular plating. All results shows as brittle deposited film. Due to the high oxidation behavior of neodymium a high amount of oxygen could be observed, which indicates a complete oxidized film.

A novel high- speed image super-resolution algorithm based on sparse representation for MEMS defect detection is proposed in this paper. Traditional super-resolution algorithms adopt a single dictionary to represent images, which cannot differentiate varieties of image blocks and leads to slow processing speed. Aiming at overcoming this shortage of traditional super-resolution algorithms, image blocks are divided into different categories by local features and each of these categories possesses the corresponding high and low resolution dictionary pairs. Experimental results of different MEMS defects show that the improved algorithm can obtain images of little lower quality with much less processing time, indicating that the proposed algorithm is more suitable for MEMS defect detection.

We present a novel approach for liquid reagent storage in lab-on-a-chip systems. A special normally-closed valving technology using thermal-release adhesive tapes is presented. The cartridge and experimental setup is explained. The thermal release tape is opened by attaching heating elements to the areas to be opened. Heating parameters were optimized and a newly developed cartridge containing nine liquid reservoirs is emptied completely automatically, including valve-opening steps and integrated pumping.
