Micro-electroforming metallic bipolar electrodes for mini-DMFC stacks

This paper describes the development of metallic bipolar plate fabrication using micro-electroforming process for mini-DMFC (direct methanol fuel cell) stacks. Ultraviolet (UV) lithography was used to define micro-fluidic channels using a photomask and exposure process. Micro-fluidic channels mold with 300 micrometers thick and 500 micrometers wide were firstly fabricated in a negative photoresist onto a stainless steel plate. Copper micro-electroforming was used to replicate the micro-fluidic channels mold. Following by sputtering silver (Ag) with 1.2 micrometers thick, the metallic bipolar plates were completed. The silver layer is used for corrosive resistance. The completed mini-DMFC stack is a 2x2 cm2 fuel cell stack including a 1.5x1.5 cm2 MEA (membrane electrode assembly). Several MEAs were assembly into mini-DMFC stacks using the completed metallic bipolar plates. All test results showed the metallic bipolar plates suitable for mini-DMFC stacks. The maximum output power density is 9.3mW/cm2 and current density is 100 mA/cm2 when using 8 vol. % methanol as fuel and operated at temperature 30 degrees C. The output power result is similar to other reports by using conventional graphite bipolar plates. However, conventional graphite bipolar plates have certain difficulty to be machined to such micro-fluidic channels. The proposed micro-electroforming metallic bipolar plates are feasible to miniaturize DMFC stacks for further portable 3C applications.Comment: Submitted on behalf of EDA Publishing Association (http://irevues.inist.fr/handle/2042/16838

Structural Box Design for High Quality Beverages

This study compared two different top designs for a wine box to determine which design gave the structure more durability. The results showed that the Twist ‘N Give, a new corrugated wine box design with a twist top, appeared to be weaker. The Twist ‘N Give is an alternative choice to the existing corrugated wine box with a traditional tuck top style. The experimental research method was used for this study. Two samples of each style of top, the twist top and the tuck top, were tested on the Lansmont Squeezer Compression Tester for the peak force and the deflection peak. The test process was destructive. The results show that the wine box with the twist top style appears to be weaker than the box with the tuck top style. However, additional testing needs to be performed, with a larger sampling of each style of top in order to verify results

Conduct Detrimental: Examining the NFL’s Collective Bargaining Agreement and the Commissioner’s Role Through a Case Study of Deflategate

This Note will closely examine whether the NFL, specifically its Commissioner, has exceeded its authority in its handling of the recent incident involving allegations of the New England Patriots and quarterback Tom Brady’s role in deflating footballs during a crucial playoff game. The Note will look at the existing the NFL current Collective Bargaining Agreement, and trace the source of the Commissioner’s power. Then it will delve into the details of the case—including the Wells Report and investigation, the arbitration process, and the District Court opinion. The Note will analyze the District Court’s opinion in anticipation of the Second Circuit’s appellate review. Finally, it will conclude by examining the history of the NFL’s Collective Bargaining Agreements and suggesting a possible solution to ensure a system of checks and balances among the players of the collective bargaining process

Speak No Evil: Circumventing Chinese Censorship

This Comment will focus on the issue of the role of American corporations in enforcing Chinese censorship law. In the hands of the Chinese government, the increased freedom of speech granted by the Internet and brought to China via American corporations is curtailed by state-sponsored censorship. To do business in China, American companies must comply with Chinese Internet censorship laws, yet these very laws not only restrain the freedom of speech of Chinese citizens but also subject offenders to the whim of the Chinese secret police. As accurately stated in the hearing, Yahoo! aided China in arresting at least two Chinese online writers for the crime of disagreeing with the government. The United States must act to stop American corporations from further participating in China\u27s persecution of its political dissidents

Informatics expertise to support life and health sciences research and industry

Computing Infrastructure and Informatics to Support Life Sciences R&D, Therapeutics, Diagnostics and Economic Development PanelInterdisciplinary collaboration between computational sciences and life/health sciences is a hallmark of the MU Informatics Institute (MUII) and its new Informatics Ph.D. program. The Institute was established to foster synergy and interdisciplinary research applications in animal, plant, human health, geospatial and microbial sciences. Creative faculty and modern computation-based research facilities combine to enable groundbreaking collaborative research that relies heavily on informatics tools and expertise. In this talk, I will briefly introduce the informatics expertise of MUII core faculty in supporting experimental scientist's R&D activities with commercialization potentials by using an example scenario in personalized medicine. There are six signature research areas that are underpinning components: (1) high-throughput sequence assembly and analysis, (2) structural bioinformatics - prediction, retrievals, and interactions, (3) large-scale and high-throughput phenotype analysis, (4) data mining and knowledge discovery from large-scale omics databases and electronic health records (5) visualization and parallelism of informatics data, and (6) geospatial informatics
