In addition, it is widely used for air pollution control (e.g., volatile organic compound (VOC) remediation) and waste gas treatment [3–6]. Plasma allows thermodynamically difficult reactions to proceed at an ambient pressure and temperature because the gas molecules are activated by energetic electrons created in the plasma. Plasma is indeed very reactive, being a cocktail of many different types of reactive species (electrons, various ions, radicals, excited species, besides neutral gas molecules), but for this reason, it is not really selective. Therefore, a catalyst is needed to improve the selectivity towards the production of targeted compounds. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood [7]. Indeed, these mechanisms are quite complicated, as the plasma will affect the catalyst and vice versa

  • Simple and Cheap Transverter for 10 Ghz
    Simple and Cheap Transverter for 10 GHz Paul Wade, W1GHZ ©2016 [email protected] I have been working on cheap and simple microwave transverters for the past 10 years, covering all bands through 5.7 GHz. Although 10 GHz is one of the most popular microwave bands, there are still technical challenges to overcome. It has taken several attempts and some lessons learned to develop a 10 GHz transverter that I believe to be reproducible and affordable – the cost should be under $100. There are at least two good commercial transverters available, but the expense may be a barrier to those who aren’t sure they are ready for 10 GHz. The other alternative, surplus, is less available than it was when many of us got started. Design Figure 1 – Circuit side of 10 GHz Transverter The 10 GHz transverter, shown in Figure 1, looks a lot like the 5760 MHz transverter 1 – three MMIC stages for transmit and three for receive, with pipe-cap filters between stages. The differences are that everything is smaller. The pipe-caps are ½ inch rather than ¾ inch and the quarter-wave bias stubs are shorter. Most important, the PC board is thinner, 1/32 inch rather than 1/16 inch. One thing I learned while developing this transverter is that ordinary 1/16 inch PC boards radiate badly at frequencies above about 7 GHz – more about this later. The design philosophy is the same as the lower frequency Cheap and Simple Transverters 2: Gain is Cheap , provided by inexpensive MMICs. We use the cheap gain to overcome losses of the other components – ordinary chip capacitors and resistors, rather than expensive microwave parts.

Signed: Lewis Breen Date: 23/07/15 Abstract The landscape of electrical supply is changing. There is a pressing need for humanity to wean itself off its reliance on finite fossil fuel resources and switch to sustainable forms of energy capture. This has led to a rapid expansion of the renewable energy sector over recent decades; in the form of both large scale renewable “farms” and smaller distributed generation. Distributed generation is of a much smaller power rating and is sourced much closer to loads – which is against the conventional model of the Megawatt rated power plant located significant distances away from its point of demand. This report looks into the renewable-based microgrid on the Isle of Eigg – a small non- grid-connected island on the West coast of Scotland.

  • Improving Institutional Access to Financing Incentives for Energy
    Improving Institutional Access to Financing Incentives for Energy Demand Reductions Masters Project: Final Report April 2016 Sponsor Agency: The Ecology Center (Ann Arbor, MI) ​ Student Team: Brian La Shier, Junhong Liang, Chayatach ​ Pasawongse, Gianna Petito, & Whitney Smith Faculty Advisors: Paul Mohai PhD. & Tony Reames PhD. ​ ACKNOWLEDGEMENTS We would like to thank our clients Alexis Blizman and Katy Adams from the Ecology Center. ​ ​ We greatly appreciate their initial efforts in conceptualizing and proposing the project idea, and providing feedback throughout the duration of the project. We would also like to thank our advisors Dr. Paul Mohai and Dr. Tony Reames for providing their expertise, guidance, and support. This Master's Project report submitted in partial fulfillment of the OPUS requirements for the degree of Master of Science, Natural Resources and Environment, University of Michigan. ABSTRACT We developed this project in response to a growing local­level demand for information and guidance on accessing local, state, and federal energy financing programs. Knowledge regarding these programs is currently scattered across independent websites and agencies, making it difficult for a lay user to identify available options for funding energy efficiency efforts. We collaborated with The Ecology Center, an Ann Arbor nonprofit, to develop an information­based tool that would provide tailored recommendations to small businesses and organizations in need of financing to meet their energy efficiency aspirations. The tool was developed for use by The Ecology Center along with an implementation plan to strengthen their outreach to local stakeholders and assist their efforts in reducing Michigan’s energy consumption. We researched and analyzed existing clean energy and energy efficiency policies and financing opportunities available from local, state, federal, and utility entities for institutions in the educational, medical, religious, and multi­family housing sectors.

  • 432 Mhz Transverter for an SDR Paul Wade W1GHZ ©2019 [email protected]
    432 MHz Transverter for an SDR Paul Wade W1GHZ ©2019 [email protected] I've been thinking about a 432 MHz Transverter for some time, to use a Software-Defined Radio like the Flex-1500 with microwave transverters with 432 MHz IF. Recently, I built one of G4DDK's Anglian 2-meter transverters, and I liked the way he used off-the-shelf parts to make filters rather than helical filters, which can be hard to find. Since printed comb filters on PC board have worked well around 200 MHz in Local Oscillators for my simple microwave transverters, I thought the comb filters might be shrunk to 432 MHz and be small enough to fit in a transverter. Then, at the start of the January VHF Sweepstakes contest, I found my 432 MHz transceiver had crapped out again. I quickly swapped in my IC-706, which worked but may be the worst CW rig around – a signal jumps right out of the passband when switching modes. Finding a weak signal again can be difficult. An SDR would eliminate this problem. Time for a transverter to replace the transceiver. A transverter capable of operating contests needs more performance than a simple microwave transverter. Using a classical engineering approach, I reviewed the G4DDK Anglian 144 MHz transverter 1 for ideas to steal. Then I worked the comb filter design to a reasonable size and adjusted it to use 18pf chip capacitors, the value I use most in other transverters. I was able to fit three filters, one common after the mixer and one each in the transmit and receive paths, in a PC board size that allowed for reasonable prototype cost.

  • New Catalytic Concepts from New Materials: Understanding Catalysis from a Fundamental Perspective, Past, Present, and Future
    Journal of Catalysis 216 (2003) 12–22 www.elsevier.com/locate/jcat New catalytic concepts from new materials: understanding catalysis from a fundamental perspective, past, present, and future Gary L. Haller Department of Chemical Engineering, Yale University, PO Box 208286, New Haven, CT 06520-8286, USA Received 8 July 2002; revised 21 August 2002; accepted 9 September 2002 Abstract The thesis of this review is that new catalytic concepts may be derived or discovered from new materials or newly recognized material properties. This thesis is demonstrated by a brief discussion of four materials, and the associated concepts, which enjoyed a certain fashion in the Journal of Catalysis and became themes of the author’s research. The four materials (or material properties) described are restricted to platinum (exemplary in most cases) supported on TiO2, yttrium-stabilized zirconia, L–zeolite, and the mesoporous molecular sieve, MCM- 41. While it was not recognized at the time, nor was it the driving force for the author’s interest, all four materials can be shown to alter catalysis by a kind of metal–support interaction that, in part or entirely, underlies the concept that is being illustrated. Thus, the common metal Pt and the emphasized catalytic property, interaction between a metal particle and an oxide support, are used as the glue to hold together a discussion of otherwise disparate catalytic systems whose selection was dictated by the interests of the author. 2003 Elsevier Science (USA).
