Given its simplicity in geometry, nanofluidic confinement, in the forms of nanoslits and nanoconstrictions, nevertheless offers unique platforms for the study of molecular biophysics and biosensing applications [1-4].We recently demonstrated a new approach, molecular dam, to enhance mass transport for protein enrichment in nanofluidic channels by nanoscale electrodeless dielectrophoresis [5] under physiological buffer conditions [6, 7].

ECS Transactions 2013年第24期58卷

作者： Li-Chung Chang Yu-Chi Hsieh Yong-Min Chen Pu-Wei Wu Jyh-Fu Lee Graduate Program for Science and Technology of Accelerator Light Source National Chiao Tung University Department of Materials Science and Engineering National Chiao Tung University National Synchrotron Radiation Research Center

Fabrication of graphene was demonstrated by electrochemical exfoliation of graphite in an ammonium hydroxide solution. The processing parameter of applied voltage was optimized to accomplish graphene productivity and desired chemical composition. Images from the atomic force microscopy showed graphene sheets with lateral sizes of several hundred nanometers. Images from the transmission electron microscopy indicated the existence of stacked graphene sheets with thickness of a few graphene layers. Raman spectroscopy confirmed variation of as-synthesized graphene and bulk graphite. X-ray photoemission spectroscopy suggested the formation of graphene oxide at large voltage.

Transcriptional factors (TF) are proteins that bind to specific bases of DNA using DNA binding domains to carry out the process of transcription. Identification of TF binding sites is essential for understanding the regulatory circuits that control cellular processes such as cell division and differentiation as well as metabolic and physiological balance [1]. In this work, we deploy a proof-of-concept method adopting bio-conjugation, nanofluidic devices and single molecule techniques for direct mapping of TF binding sites on field stretched single DNA molecules. Here we demonstrated a simple and robust system for TF binding site identification, complementary to the existing techniques practiced in this field.

IEEE Conference on Electron Devices and Solid-State Circuits

作者： Panus Sinsoontornpong Apisak Worapishet The Electrical Engineering Graduate Program Faculty of Engineering Mahanakorn University of Technology Bangkok Thailand Mahanakorn Microelectronics Research Center (MMRC) Mahanakorn University of Technology Bangkok Thailand

A bandwidth enhancement technique for a resistive shunt-feedback transimpedance amplifier (TIA) is developed in this paper. The technique relies upon a π-peaking network realization using the shunt-feedback TIA as part of the network in order to offer a high bandwidth while maintaining a low noise performance. The output is obtained by making use of subsequent amplifier stages with the non-uniform constant-k output network for simultaneously high gain and bandwidth. Practical performance verification was provided via the design and simulation of a 50 dB·O 10-GHz π-peaking TIA, where it clearly exhibits a superior bandwidth over the conventional TIA.

IEEE Symposium Power Modulator

The transient thermal shock (TTS) is instantaneous temperature change, more than ten degrees within seconds, caused by the pulsed electric fields. The famous thermal effect is heat shock (42-45°C for more than 10 min), we call it stationary heat shock (SHS) in this paper. However, the temperature history of TTS is quite different from SHS. Living organ have never been exposed the rapid temperature change like TTS, TTS may provide a novel biological stress. Here, we compare the effect of these three agents, the field-induced TTS, the non-thermal (NTFE) 100 MHz burst fields effects and the SHS. Instantaneous temperature of cell suspending media during the pulse application was monitored by a fast radiation thermometer. The electric field ranges were 0.25, 1, 4 kV/cm and the temperature ranged from 25 to 85°C, respectively. The viability was detected by using propidium iodide (PI) and statistically evaluated by using a flow cytometer. In all electrics fields, the percentage of PI positive cells was increased by temperature-dependently. Moreover, in all electric fields, the percentage of PI positive cells was increased by time-dependently.

Nucleation or granule nuclei formation is an important step in the formation of anaerobic granules. This research was aimed to investigate the formation and time for granule nuclei under the addition of synthetic and natural cationic polymers. In addition, the increase activity of synthroph microorgansm in granule nuclei by adaptation with volatile fatty acid (VFA) was also studied. Three UASB reactors were used namely R1, R2 and R3 as control, addition of synthetic and natural polymers, respectively. Three reactors were operated under identical conditions. VFA was used as main substrate to adapt seed sludge and built synthroph microbial nuclei. Based on size distribution, nucleation was achieved at day 69 in R2 with average diameter size about 126 μm, size distribution 50.7% of >100 μm-aggregates and SVI 42 ml.g -1 SS. The activities of specific non-methanogens and methanogen in reactors added polymers (R2 and R3) were lower than control reactor. However, adaptation of specific microorganism succeed due to their activities from methanogens, propionate- and butyrate- degrading microorganism were higher than initial activities. R2 showed as better cationic polymer compared to chitosan for shortening nucleation phase.
