carbon nanotube pattern formation precise routing on silicon oxide using nanoscale catalyst Breadboards
IEEE Transactions on Nanotechnology, 2012Co-Authors: Chris PapadopoulosAbstract:A method for directly routing single-walled carbon nanotubes on silicon dioxide is presented. The lack of a preferred direction on the amorphous oxide film was overcome by placing nanoscale catalyst particles on the surface in the form of a grid or breadboard. Colloidal lithography was used to create an ordered nanoscale array of uniformly distributed Fe/Mo catalyst particles to serve as the breadboard. Following chemical vapor deposition at 900 °C with a methane/hydrogen gas mixture, intricate nanotube patterns that corresponded to the underlying breadboard were formed. Most patterns were found to consist of individual tubes or few-tube bundles. A “lift-and-drop” model was used to describe the nanotube pattern formation process whereby a combination of gas flow and van der Waals interactions allows tube growth to be precisely guided onto the Breadboards without requiring an external impetus. These results indicate a potential path to carbon nanotube integration on standard oxide films for future deep nanoscale electronics.

CHI - AutoFritz: Autocomplete for Prototyping Virtual Breadboard Circuits
Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems - CHI '19, 2019Co-Authors: Jo-yu Lo, Da-yuan Huang, Jun Gong, Teddy Seyed, Xing-dong Yang, Bing-yu ChenAbstract:We propose autocomplete for the design and development of virtual breadboard circuits using software prototyping tools. With our system, a user inserts a component into the virtual breadboard, and it automatically provides a user with a list of suggested components. These suggestions complete or ex- tend the electronic functionality of the inserted component to save the user's time and reduce circuit error. To demon- strate the effectiveness of autocomplete, we implemented our system on Fritzing, a popular open source breadboard circuit prototyping software, used by novice makers. Our autocomplete suggestions were implemented based upon schematics from datasheets for standard components, as well as how components are used together from over 4000 circuit projects from the Fritzing community. We report the results of a controlled study with 16 participants, evaluating the effectiveness of autocomplete in the creation of virtual breadboard circuits, and conclude by sharing insights and directions for future research.

Progress in development of ultra-lightweight solar panel using space solar sheet
Conference Record of the IEEE Photovoltaic Specialists Conference, 2010Co-Authors: Kazunori Shimazaki, Tatsuya Takamoto, Takehiko Ito, Masato Takahashi, Mitsuru Imaizumi, Yuki Kobayashi, Yukishige NozakiAbstract:Development of an ultra-lightweight solar panel using space solar sheets is currently being carried out. The panel utilizes space solar sheets consisting of InGaP/GaAs dual-junction high-efficiency thin-film solar cells. The panel employs a simple frame-type structure. The initial breadboard model consisted of three main panels and two lateral panels. The dimensions of the 1.0-cm-thick unit panel were about 55 cm × 70 cm. In this study, the initial breadboard model was improved. The lateral panels were trimmed of weight while maintaining adequate stiffness. Additionally, unique deployment mechanisms for the lateral panels were adopted. The new system is much lighter than the conventional spring-driven mechanism, and as a result, the improved model finally achieved the high specific power of 100 W/kg. © 2010 IEEE.

A breadboard model was manufactured. The dimensions of the 1.0-cm-thick unit panel were about 55 cm x 70 cm. Each panel weighs approximately 0.68 kg. In addition to three basic panels, two lateral panels were recently developed and added to the basic panel. This breadboard model achieved high specific power of about 91 W/kg. Moreover, five panels were stacked, resulting in a total thickness of 6 cm. Acoustic and sine vibration tests were performed on the model. The results demonstrated the high durability of the ultra-lightweight solar panel in an acoustic and vibration environment. ©2009 IEEE.

KooijmanAbstract:TNO has developed a compact BreadBoard (BB) cryogenic Optical Delay Line (ODL) for use in future space interferometry missions such as ESA's Darwin. The breadboard delay line is representative of a flight mechanism. The optical design is a two-mirror cat's- eye. A single stage linear guiding system based on magnetic bearings provides frictionless and wear free operation with zero hysteresis. The delay line has a voice coil actuator for Optical Path Difference (OPD) control. The verification program, including functional testing at 40 K, has been completed and showed compliance with all important requirements.
