RE:PRINT edited by Véronique Chance and Duncan Ganley, brings together the work of twenty contemporary artists working in the field of expanded printmaking, to explore the relationship between print media, interdisciplinary art and new technologies. A hybrid of art object, book, physical and electronic form, RE:PRINT addresses concerns of reproducibility, technical developments and inter-medial approaches in contemporary art. Through an interplay of image and text from a diverse range of practitioners, RE:PRINT critically rethinks the notion of ‘print’ as both artwork and published multiple and debates what is print in the twenty first century. RE:PRINT includes work by: Jo Stockham, Jo Love, Steve Lovett, Rob Smith, Asim, Véronique Chance, Susana Gómez Larrañaga, Kelcy Davenport, Nerma Cridge, Fay Hoolahan, Richard Kearns, Annis Fitzhugh, James Hutchinson, Monique Jansen, Duncan Ganley, Mark Shaw, Nick Devison, Mark Graver, Meg Rahaim and Emily Godden.

Forecasting banknotes
No full textA central bank’s liquidity forecast is important in ensuring that it supplies the banking system’s need for central bank money. Banknote (or currency in circulation) demand is the largest and for some central banks the most variable component of the liquidity forecast. Accurate forecasting of banknotes is essential in ensuring an accurate liquidity forecast and in turn effective monetary policy implementation. This Handbook discusses these issues and outlines a structural time series state space (STSSS) model which is now used by central banks including the Bank of England and ECB to forecast banknotes (currency in circulation).Forecasting banknotes

Microreactors for the Production of Hydrogen From Ammonia
No full textThis work describes the development of structured aluminum-anodized alumina microreactors that exhibit high catalytic activity for the decomposition of anhydrous ammonia to nitrogen and hydrogen at moderate temperatures. Experiments involving reactor fabrication methods and optimizations of reactor catalyst support were performed. Correlations for the prediction of catalytic activity of possible catalyst metals for use in the reactor were also tested experimentally. Modifications such as adjustments to the geometry of the microreactor features, surface area enhancement of the anodized catalyst support, choice of Ru precursor, and application of a catalyst promoter are each shown to affect the reactor performance to varying degrees. Microreactors of this type have potential uses for a variety of small-scale heterogeneously catalyzed reactions, especially in mobile applications where monolithic structures are advantageous. The best-performing microreactor converts approximately 99% of ammonia at 600°C into the equivalent of 60 W of hydrogen, which is enough to power a laptop computer if the reactor is coupled to a PEM fuel cell system.Made available in DSpace on 2015-09-25T20:43:20Z (GMT).

A heterogeneous chemical reactor analysis and design laboratory: The kinetics of ammonia decomposition
No full textDesign and optimization considerations of advanced catalytic membrane reactors for efficient ammonia synthesis and decomposition
No full textIncludes bibliographical references.2021 Spring.The conversion of distributed renewable electricity into liquid ammonia is a promising vector for hydrogen transport and storage, decarbonizing ammonia production and enabling efficient hydrogen distribution. This thesis describes the development of the catalytic membrane reactor (CMR) technology as a compact, effective, and low-cost solution for decentralized and scalable processes of ammonia synthesis and decomposition. We introduce a CMR configuration where the membrane and catalyst are in intimate proximity, mitigating mass transport limitations, and realizing record hydrogen productivity from ammonia decomposition using less catalyst mass at reduced temperature (≤ 450°C). A numerical simulation of the CMR captures the experimental results with high fidelity, identifying rate-limiting regimes, and illustrating pathways for further improvement. A Ru/α-alumina catalyst was shown to be more active than Ru/YSZ and adding it to the interior of the CMR significantly improves the performance, including increased conversion and doubled hydrogen productivity. Clinoptilolite is identified as a low-cost, reusable adsorbent that reduces residual ammonia in the permeate stream from ∼1000 ppm exiting the CMR to the ultra-high purity standards (< 0.1 ppm) required by fuel cell electric vehicles. The second topic focused on the development of CMR configurations for ammonia synthesis reactions at mild temperature and pressure. Yttria-stabilized zirconia (YSZ) is demonstrated to be a highly active support for Ru catalysts. A number of alkali and alkaline-earth metal promoters were evaluated with Ba found to be stable and deliver the highest specific activity reported to date. A microkinetic model was developed that was capable of capturing the strong dependence on the H2/N2 ratio and temperature, highlighting the importance of surface coverage in controlling the kinetics. Alternatively, a low-cost Cs-Fe/γ-alumina catalyst was developed that reached ∼ 50% of the activity of the Ba-Ru/YSZ catalysts. Finally, a reactor simulation study was conducted to quantify the potential of the CMR configuration for the scalable synthesis of ammonia. The ammonia permeance controls conversion and recovery whereas purity scales with an effective selectivity. A thermally stable membrane could enable effective ammonia synthesis at much milder conditions (P < 30 bar, T < 400°C) than the conventional Haber Bosch process
Material and operational considerations for effective use of palladium composite hydrogen separation membranes in ammonia decomposition membrane reactors
No full textIncludes bibliographical references.2017 Summer.In this work, the effects on hydrogen permeation of various operating conditions and support materials are explored. The primary topic explored was focused on the viability of pure Pd films to be used in ammonia decomposition catalytic membrane reactors. In such a reactor, the Pd membrane is surrounded by an ammonia decomposition catalyst, which allows hydrogen to be removed simultaneously as the decomposition occurs. To this end, the first section details effects on hydrogen permeance from nitrogen and ammonia adsorption. Essentially, no effects were observed and Pd is proposed as a potential candidate without any alloying or protective actions. The second topic then explores a peculiar effect on hydrogen permeation due to high-pressure gas exposures. It is observed that at pressures of 3.0 MPa, inert gases such as argon can assist in surface morphological changes that affect hydrogen permeation by smoothening. This appears to anneal surface defects, which negatively affects the hydrogen rate of sorption into the palladium films. The document then proceeds to study the effects of support materials, wherein permeating hydrogen was observed to reduce a MgO/MgAl2O4 support and cause Mg to alloy with the Pd film. The Mg was observed to segregate to the surface of the Pd film and essentially block all hydrogen permeation by not allowing contact with Pd. Finally, a strategy for sealing defects in supported Pd films is detailed wherein a low melting point ceramic frit is mixed with water and dripped onto the defect. This is then fired under an inert atmosphere at the frit melting temperature whereat the frit melts into the defect and completely seals the hole. This allows large defects on a fabricated Pd membrane to be sealed, thus salvaging an otherwise ruined membrane. Furthermore, the sealed membrane was tested for an extended duration in an ammonia decomposition membrane reactor to prove its utility as a sealing technique for realistic applications
