The Great Financial Plumbing: From Northern Rock to Banking Union. CEPS Paperback, 19 October 2015

The financial and economic crises have led to an enormous plumbing exercise, involving a fundamental re-design of the global and European regulatory and supervisory system. This book systematically assesses the big items on the G-20 and EU agendas and the effectiveness with which they have been implemented in the EU. Its publication coincides with the demand by European Commissioner Jonathan Hill, in the context of the Capital Markets Union, for a 'comprehensive review' of the impact and coherence of EU legislation in the area of financial services. Karel Lannoo argues in the book that much has been done by European policy-makers to make the financial system safer and to prevent banking crises of the magnitude that erupted in 2008 and 2011, but that the new framework puts an enormous burden on banks and supervisors to implement and enforce it correctly. With the huge amount of secondary or 'level-2' legislation in place, this process has spiralled out of control, and as member states always find new ways of ‘gold-plating’ EU rules, the EU always finds further reasons to achieve a 'single rulebook'. This process has to be brought to a halt, and mutual recognition, a basic single-market principle, reinforced. The new framework also brings huge advantages, which should offer benefits to all parties. Banking Union is a huge step forward, which introduces 'one-stop shopping' for banks in the eurozone, another basic single market principle, and a true single supervisor. The clarity of the new resolution framework should, if correctly applied, trigger early intervention and bring an end to forbearance, thereby enforcing market discipline in the banking sector. It should also avoid reliance on taxpayers' money to bail-out banks in trouble, which totalled 14% of EU GDP during the crisis.

Electrochemical deposition of cupric ions for the determination of mass transfer rates to a stepped rotating cylinder electrode

The stepped rotating cylinder electrode (SRCE) geometry has been developed as a simple aid to the practical study of the flow-enhanced corrosion and applied electrochemistry problems commonly observed under conditions of disturbed, turbulent flow. The electrodeposition of cupric ions from an acid sulphate plating bath has been used to characterise differential rates of mass transfer to the SRCE. The variation in thickness of electrodeposited copperfilms has allowed the mapping of local rates of mass transfer over the active surface of this geometry. Both optical and scanning electron microscopy were used for the examination of metallographic sections to provide a high resolution evaluation of the distribution of mass transfer coefficient. Results are also discussed using the convective-diffusion model in combination with the existing direct numerical flow simulation (DNS) data for this geometry.

Cytokine-specific Gene-knockout Studies in Oropharyngeal Candidiasis

Oropharyngeal candidiasis is a common clinical problem encountered in patients with defects in innate or cell-mediated immunity. We have previously shown that recovery from chronic oropharyngeal candidiasis is dependent on CD4+ T-cell augmentation of neutrophil and macrophage candidacidal activity, and that the immune response is characterised by the production of cytokines such as IL-12 and IFN-gamma by cells in the local draining lymph nodes, and by the expression of TNF-alpha in the oral tissues. Objective: The purpose of this study was to elaborate on the role of these cytokines in recovery from oropharyngeal candidiasis, by using cytokine-specific gene-knockout mice. Methods: These mice are created by targeted gene mutation (tm1) of embryonic stem (ES) cells microinjected into host embryos. IL-4, IL-10, IL-12, IFN-gamma and TNF-alpha knockout mice, and appropriate controls, were infected orally with 108 viable C. albicans yeasts. The infection was quantified by swabbing the oral cavity and plating on Sabouraud's agar. Results: Tnftm1mice developed an acute severe infection characterized by an increased fungal load in the early stages of infection, but cleared the yeast within the same time frame as control mice (21 days). On the other hand, Il12btm1 mice developed a chronic oropharyngeal infection (120 days) similar to that seen in T-cell deficient (Foxn1nu/Foxn1nu) mutant mice. There was no significant difference between Il4tm1, Il10tm1, and Ifngtm1 mice and their respective controls. Conclusions: Tnftm1 mice may be rendered more susceptible through impaired recruitment of phagocytic cells, and/or impaired killing of C. albicans, whereas Il12btm1 mice may not be capable of activating naïve T-cells or inducing an appropriate cellular immune response.

Development and evaluation of a non-destructive adhesion test

The object of this work was to further develop the idea introduced by Muaddi et al (1981) which enables some of the disadvantages of earlier destructive adhesion test methods to be overcome. The test is non-destructive in nature but it does need to be calibrated against a destructive method. Adhesion is determined by measuring the effect of plating on internal friction. This is achieved by determining the damping of vibrations of a resonating specimen before and after plating. The level of adhesion was considered by the above authors to influence the degree of damping. In the major portion of the research work the electrodeposited metal was Watt's nickel, which is ductile in nature and is therefore suitable for peel adhesion testing. The base metals chosen were aluminium alloys S1C and HE9 as it is relatively easy to produce varying levels of adhesion between the substrate and electrodeposited coating by choosing the appropriate process sequence. S1C alloy is the commercially pure aluminium and was used to produce good adhesion. HE9 aluminium alloy is a more difficult to plate alloy and was chosen to produce poorer adhesion. The "Modal Testing" method used for studying vibrations was investigated as a possible means of evaluating adhesion but was not successful and so research was concentrated on the "Q" meter. The method based on the use of a "Q" meter involves the principle of exciting vibrations in a sample, interrupting the driving signal and counting the number of oscillations of the freely decaying vibrations between two known preselected amplitudes of oscillations. It was not possible to reconstruct a working instrument using Muaddi's thesis (1982) as it had either a serious error or the information was incomplete. Hence a modified "Q" meter had to be designed and constructed but it was then difficult to resonate non-magnetic materials, such as aluminium, therefore, a comparison before and after plating could not be made. A new "Q" meter was then developed based on an Impulse Technique. A regulated miniature hammer was used to excite the test piece at the fundamental mode instead of an electronic hammer and test pieces were supported at the two predetermined nodal points using nylon threads. This instrument developed was not very successful at detecting changes due to good and poor pretreatments given before plating, however, it was more sensitive to changes at the surface such as room temperature oxidation. Statistical analysis of test results from untreated aluminium alloys show that the instrument is not always consistent, the variation was even bigger when readings were taken on different days. Although aluminium is said to form protective oxides at room temperature there was evidence that the aluminium surface changes continuously due to film formation, growth and breakdown. Nickel plated and zinc alloy immersion coated samples also showed variation in Q with time. In order to prove that the variations in Q were mainly due to surface oxidation, aluminium samples were lacquered and anodised Such treatments enveloped the active surfaces reacting with the environment and the Q variation with time was almost eliminated especially after hard anodising. This instrument detected major differences between different untreated aluminium substrates.Also Q values decreased progressively as coating thicknesses were increased. This instrument was also able to detect changes in Q due to heat-treatment of aluminium alloys.

Workers' understanding of chemical risks: electroplating case study

BACKGROUND: There is limited research concerning how small companies in particular, respond to health and safety messages. AIMS: To understand individuals' knowledge and beliefs about chemical risks and to compare these with those of experts. METHODS: The use of chromic acid in particular, and also other chemicals associated with chrome plating were studied. All chromium plating firms were based in the West Midlands. The methodology involved initial face to face interviews (n = 21) with chromium platers, structured questionnaires (n = 84) to test the prevalence of beliefs identified in the interviews, an expert questionnaire, and a workshop to discuss findings. The responses of platers were compared with those of occupational health and safety experts. RESULTS: Although chromium platers appeared to understand the short term adverse effects of the chemicals to which they are exposed, their understanding of long term, or chronic effects appeared to be incomplete. They had good knowledge of acute effects based primarily on experience. Platers were aware of the hazardous nature of the chemicals with which they work, but did not draw distinction between the terms "hazards" and "risks". They had difficulties articulating the effects of the chemicals and how exposure might occur; although it is inappropriate to equate this with lack of knowledge. A significant minority of platers displayed deficiencies in understanding key technical terms used in Safety Data Sheets. CONCLUSIONS: This study provides a method which can be used to gain some understanding of workers' knowledge and beliefs about risks that they are exposed to in the workplace. The study also identifies gaps between the platers' knowledge and beliefs and those of experts. New risk information needs to be designed which addresses the information needs of platers using language that they understand.

The influence of composition on the optical properties of electrodeposited gold

In industry the colour of a gold alloy electrodeposit is checked by visual comparison with standard panels. The aims of the present work have been to access the application of spectrophotmetric techniques to the measurement of the colour of gold alloy electrodeposits and to examine the factors that influence the colour of thin deposits. The minimum thickness of deposit required to produce its final colour and completely hide the underlying substrate was measured and found to depend on the nature of the substrate, the plating solution and the operating conditions. Bright and matt electrodeposits were studied. The influence of alloying gold by adding copper, silver and indium to the plating solution were investigated. CIE chromaticity coordinates were calculated from spectrophotometric data using a computer programme written for the purpose. The addition of silver to a simple gold bath caused the colour of the deposit to change from yellow through green to near white in a smooth progression as the amount of silver in solid solution steadily increased. The colour of deposits formed when additions of copper were made was complicated by the formation of intermediate phases. À colour in the blue region of the spectrum was obtained in a few experiments investigating the influence of indium additions to the gold bath.

Electrodeposition of corrosion resistant zinc alloy coatings

With the increase use of de-icing salts on roads for safety, the need for improved corrosion resistance of the traditional galvanized automobile bodies has never been greater. In the present work, Zn alloy coatings (Zn-Ni and Zn-Co) were studied as an alternative to pure Zn coatings. The production of these deposits involved formulation of various acidic (pH of about 5.5) chloride based solutions. These showed anomalous deposition, that is, alloys were deposited much more easily than expected from the noble behaviour of Ni and Co metals. Coating compositions ranging from 0 to about 37% Ni and 20% Co were obtained. The chemical composition of the coatings depended very much on the electrolytes nature and operating conditions. The Ni content of deposits increased with increase in Ni bath concentration, temperature, pH and solution agitation but decreased considerably with increase in current density. The throwing power of the Zn-Ni solution deteriorated as Ni metal bath concentration increased. The Co content of deposits also increased with increase in Co bath concentration and temperature, and decreased with increase in current density. However, the addition of commercial organic additives to Zn-Co plating solutions suppressed considerably the amount of Co in the coatings. The Co content of deposits plated from Zincrolyte solution was found to be more sensitive to variation in current density than in the case of deposits plated from the alkaline Canning solution. The chromating procedures were carried out using laboratory formulated solution and commercially available ones. The deposit surface state was of great significance in influencing the formulation of conversion coatings. Bright and smooth deposits acquired an iridescent colour when treated with the laboratory formulated solution. However, the dull deposits acquired a brownish appearance. The correlation between the electrochemical test results and the neutral salt spray in marine environment was good. Non-chromated Zn-Ni coatings containing about 11-14% Ni increased in corrosion resistance compared to pure Zn. Non-chromated Zn-Co deposits of composition 4-8% were required to show a significant improvement in corrosion resistance Corrosion resistance was improved considerably by conversion coating. However, the type of conversion coating was very important. Samples treated in a laboratory solution performed badly compared to those treated in commercial solutions. Zn alloy coatings were superior to pure Zn, the Schloetter sample (13.8% Ni) had the lowest corrosion rate, followed by the Canning sample (1.0% Co) and then Zincrolyte (0.3% Co).Neither the chromium content of the conversion films nor the chromium state was found to have an effect on corrosion performance of the coatings.

Wear and corrosion of mechanical seals

Mechanical seals are used extensively to seal machinery such as pumps, mixers and agitators in the oil, petrochemical and chemical industries. The performance of such machinery is critically dependent on these devices. Seal failures may result in the escape of dangerous chemicals, possibly causing injury or loss of life. Seal performance is limited by the choice of face materials available. These range from cast iron and stellited stainless steel to cemented and silicon carbides. The main factors that affect seal performance are the wear and corrosion of seal faces. This research investigated the feasibility of applying surface coating/treatments to seal materials, in order to provide improved seal performance. Various surface coating/treatment methods were considered; these included electroless nickel plating, ion plating, plasma nitriding, thermal spraying and high temperature diffusion processes. The best wear resistance, as evaluated by the Pin-on-Disc wear test method, was conferred by the sprayed tungsten carbide/nickel/tungsten-chromium carbide deposit, produced by the high energy plasma spraying (Jet-Kote) process. In general, no correlation was found between hardness and wear resistance or surface finish and friction. This is due primarily to the complexity of the wear and frictional oxidation, plastic deformation, ploughing, fracture and delamination. Corrosion resistance was evaluated by Tafel extrapolation, linear polarisation and anodic potentiodynamic polarisation techniques. The best corrosion performance was exhibited by an electroless nickel/titanium nitride duplex coating due to the passivity of the titanium nitride layer in the acidified salt solution. The surface coating/treatments were ranked using a systematic method, which also considered other properties such as adhesion, internal stress and resistance to thermal cracking. The sealing behaviour of surface coated/treated seals was investigated on an industrial seal testing rig. The best sealing performances were exhibited by the Jet-Kote and electroless nickel silicon carbide composite coated seals. The failure of the electroless nickel and electroless nickel/titanium nitride duplex coated seals was due to inadequate adhesion of the deposits to the substrate. Abrasion of the seal faces was the principal wear mechanism. For operation in an environment similar to the experimental system employed (acidified salt solution) the Jet-Kote deposit appears to be the best compromise.
