Experimental study of hardness and corrosion properties of AZ91 magnesium alloy after electroless nano composite coating

Magnesium and its numerous alloys have excellent rigidity, low density, and electromagnetic protection properties, making them ideal for usage in numerous industrial components. Magnesium alloys have a significant disadvantage in terms of corrosion and hardness, which restricts their practical uses. One of the most recent ways for improving the corrosion and hardness of Mg alloys is electro-less nano-coating. The experimental research of corrosion and hardness of AZ91 Mg Alloy due to nano composite coating procedures of ENi-B-TiO2is examined in this study. It would be useful to conduct a thorough examination, including experimental analysis, into the possibilities of increasing the deposit efficiency and characteristics of composite deposits by designing a suitable bath composition and operating circumstances. It has been discovered that as the concentration of titania particles increases, so does the surface hardness of coatings. The optimal concentration of second-phase (titania) particles and bath agitation are also examined in order to get superior surface properties following nano coating. Following this nano coating, the materials may be employed for a variety of materials engineering applications.

Global Financial Crisis and Islamic Bank Efficiency: Are Efficiencies Stable or Impacted? Evidence From Malaysian Islamic Banks

In examining the impact of the global financial crisis on loan and deposit efficiencies, Data Development Analysis (DEA) is applied in estimating the technical efficiency of loans and deposits of the Islamic of Malaysia during 2008-2013. This study found that the average loan efficiency was 0.83., 0.88, 0.87, 0.95, 1.0, and 0.94 and the deposit efficiency was 0.87, 0.94, 0.94, 0.96, 0.92, and 0.96 during 2008-213 respectively. A comparison of two efficiencies found deposit efficiency dominated the loan efficiency. Second, in testing stability of the efficiencies, this paper used both parametric and the non-parametric tests, as suggested by Jarque Bera Test. Results of parametric test,( ANOVA F-test, t-test, and Welch F-test, and the non-parametric tests, Wicoxon/Mann-Whitney, Median Chi-square, performed on loans and deposits between the global financial crisis period and the post global financial crisis period, found no significant differences between efficiencies of the two period. The failure to reject the null hypothesis of the equality of the mean and median efficiencies between the global financial crisis and the post global financial crisis period suggests that the efficiencies of the Islamic banks of Malaysia are stable. The global financial crisis had no impact on the technical efficiencies of the Islamic banks of Malaysia.

Improving the deposit efficiency of nano composite deposits on AZ91 magnesium alloy by using a suitable bath composition and operating conditions

The purpose of applying the nano-coating may be either decorative, functional, or a combination of both. The magnesium alloys specially AZ91 possesses great specific stiffness, less density, and electromagnetic protecting characteristics, which attracts the use of this type of material for several industrial parts. But the surface roughness and hardness is a major weakness of magnesium alloys, limiting their practical uses. Electroless nano-coating is one of the useful techniques for enhancement in these material characteristics. In this research, experimental analysis of various surface properties of magnesium alloy (AZ91) due to electroless nano-composite coating is investigated. The possibility of enhancing the efficiency and the properties of the composite depository material would be a valuable attempt, by finding a suitable chemical bath compositions and operating conditions of electroless nano-coating method. It has been detected that, as the concentration of titanium particles increases, the roughness value, hardness value, and corrosion property of coatings increases. The optimal value of the concentration of titanium particles TiO2 is also explored for gaining better surface property after coating.

Evolution characteristic of axial magnetic field and Nernst effect in magnetized liner inertial fusion

Axial magnetic field is one of the main parameters of magnetized liner inertial fusion (MagLIF), which is greatly different from other traditional inertial confinement fusion configurations. The introduce of axial magnetic field dramatically increases energy deposit efficiency of alpha particles, when initial <i>B</i><i><sub>z</sub></i> increases from 0 to 30 T, the ratio of deposited alpha energy rises from 7% to 53%. In the MagLIF process, the evolvement of magnetic flux in fuel can be roughly divided into three main stages: undisturbed, oscillation, and equilibrium. The distributions and evolution characteristic of axial magnetic field are both determined by the liner conductivity, fuel conductivity, and the fluid dynamics. The pressure imbalance between fuel and liner, caused by laser injection, is the source of fluid oscillation, which is an intrinsic disadvantage of laser preheating method. This fluid oscillation does not lead the magnetic flux to decrease monotonically in the fuel during implosion process, but oscillate repeatedly, even increase in a short time. Nernst effect plays a negative role in MagLIF process. As initial axial magnetic field decreases from 30 to 20 to 10 T, the Nernst effect causes magnetic flux loss to increase from 28% to 44% to 73% correspondingly, and the deposited alpha energy ratio drops from 44% to 27% to 4% respectively. So the initial magnetic field is supposed to be moderately high. The radial distribution of temperature in fuel should be as uniform as possible after preheating, which is helpful in reducing the influence of Nernst effect. Compared with Nernst effect, the end loss effect is much responsible for rapid drawdown of fusion yield. A large number of physical images are acquired and summarized through this work, which are helpful in understanding the process of magnetic flux compression and diffusion in MagLIF process. The simulation can act as a powerful tool and the simulation results can serve as a useful guidance for the future experimental designs.

How monetary policies and ownership structure affect bank supply chain efficiency: a DEA-based case study

PurposeThe banking industry plays a key role in China's financial industry. In the past decade, the speed of the development of China's commercial banks has gradually declined. Commercial banks with different ownership structures also have certain differences in terms of operating efficiency, and their monetary policies are often different. Therefore, the authors study the impact of ownership structure on the efficiency of commercial banks under different monetary policies. This study also provides relevant reference opinions with regard to the healthy, sustainable and stable development of China's banking industry.Design/methodology/approachThis paper mainly uses the two-stage data envelope analysis (DEA) model under meta-frontier and group frontier to study the deposit and loan efficiency changes of 16 banks from 2007 to 2014 under ownership structure heterogeneity. Furthermore, the model introduces the balance parameters between deposits and loans, in order to realize the mathematical abstraction description of macro-monetary policy.FindingsFirst, based on bank efficiency analysis, the paper finds that most banks' loan efficiency is higher than their deposits. Second, the paper concludes that different monetary policies have little effect on bank deposit and loan efficiency, while ownership heterogeneity has a significant impact on bank performance. Finally, through the decomposition of the sources of inefficiency in bank performance, this paper finds that management and technology are two factors that affect the inefficiency of banks.Originality/valueThe authors work contributes to the existing literature in the following ways: First, to the best of the authors’ knowledge, this is the first attempt to use the DEA model to study the relationship between monetary policies and bank supply chain efficiency. The results may provide additional managerial implications for the banking industry from the perspective of monetary policies. The result is helpful in terms of explaining how and why banks should strengthen risk management, as well as how to deal with non-performing loans in management terms and finally, why banks should make financial technology innovations in technology terms.

Empirical Investigation on Determinants of Lending Behaviour: Evidence from Commercial Banks in Ethiopia

This study was carried out to investigating determinants to lending behaviour in commercial banks of Ethiopia from 2010- 2017. The study tried to investigate bank specific and macroeconomic determinants of lending behaviour based on data of eleven commercial banks in Ethiopia by using deposit ratio, liquidity ratio, bank size, efficiency ratio and banks ownership as bank specific factors and Reserve requirement ratio, exchange rate, lending rate, inflation rate and gross domestic product as macroeconomic determinants of lending behaviour. The study also sought to examine lending disparity among banks under the investigation by taking into account individuality of each bank through dummy variable. Data was obtained from national bank of Ethiopia and world bank data base and analyzed through panel data regression analysis by applying fixed effect regression model. The finding revealed that from bank specific factors, deposit ratio and bank ownership have positive and significant effect on lending behaviour of banks under the investigation. On the other hand, liquidity ratio, bank size and efficiency ratio have negative but statistically insignificant effect on lending behaviour. The finding also shows that from macroeconomic factors, exchange rate, lending rate and gross domestic product have found to have positive but statistically insignificant effect on lending behaviour. Result on macroeconomic factors also shows that reserve requirement ratio and inflation rate have negative but insignificant effect on lending behaviour of banks under the investigation. Finally, the study revealed existence of statistically significant disparity between CBE and other banks under the investigation in terms of lending behaviour.

The Research of Yttria Stabilized Zirconia Coatings formed by a low Pressure Thermal Spraying Plasma Torch

To enhance deposit efficiency and improve quality of the coatings of the Yttria stabilized zirconia (YSZ) formed by the thermal plasma spraying method. A new kind plasma touch with diverging-converging nozzle and an internal powder feedstock were designed. The optical emission spectroscopy method was used for evaluating powder molten and vaporized degrees. The results indicated that the plasma jet produced by the two kinds of plasma gases under the 700 a condition made the feedstock powder of YSZ vaporized partially, but different melting degrees. Denser column microstructure YSZ coatings were first successfully deposited at an arc current of 700 A by using Ar-He-H2 plasma gas. In the Ar-H2 plasma jet, the temperature is higher at the same axial distance. The micro-hardness of the coatings deposited by Ar-He-H2 plasma gases is higher.

Measuring Taiwanese bank performance: A two-system dynamic network data envelopment analysis approach

This paper deals with the heterogeneity problem related to the determination of meta-technology when measuring performance in a dynamic setting. The authors propose a new way of constructing the non-convex meta-framework of the dynamic network data envelopment analysis. This new approach differs from the minimum extrapolation principle on the aggregation of individual group technologies. The proposed model preserves the role of each group's technology in the determination of the proposed non-convex meta-technology. The proposed model also considers the linking activities between the processes and the carry-over activities between two consecutive terms, illustrated by means of a real-world example from banking that simultaneously evaluates: deposit, lending, period, deposit-period and lending-period efficiencies for 22 Taiwanese banks from 2008 to 2016. The empirical results indicate that lending efficiency outperforms deposit efficiency during the sample period, and thus the improvement in deposit activity has a positive effect on banks’ overall performance. The results also imply that non-FHC banks outperform FHC banks on average in terms of both the deposit and lending processes, but the effect is not statistically significant.

DEA considering technological heterogeneity and intermediate output target setting: the performance analysis of Chinese commercial banks

This study proposes a two-stage data envelopment analysis model based on the meta-frontier boundary and intermediate output goal setting. Comparing to the traditional models, the proposed model is able not only to consider technology heterogeneity of decision making units, but also to target the intermediate output. The proposed model was applied to an analysis of 28 Chinese commercial banks (CCBs). Empirical analysis has obtained some valuable research results. First, the efficiency of the CCBs’ deposit sub-system is not very high, especially in terms of the deposit efficiency of city commercial banks (CBs). Second, in the deposit sub-system, the efficiency gap among state-owned commercial banks (SBs) is higher than the joint stock commercial banks (JBs) and the CBs. Third, in the loan sub-system, the efficiency gap among SBs and CBs is higher than that in the JBs. Fourth, the deposits of more than half of CCBs are not on the frontier of efficiency, showing that the financial resource allocation of CCBs is severely ineffective. Finally, this study divides CCBs into four categories and provides specific recommendations to improve performance and deposit target setting.

Electrochemical deposition of Zinc on mild steel

Zn coating electrodeposited on a mild steel substrate in an acid bath was investigated using cyclic voltammetric and chronopotentiometry techniques. The effect of the current density on the deposition potential, the thickness of the deposit, deposition rate and current efficiency was investigated. The chemical composition and surface morphology of Zn coatings are characterized using Energy Dispersive X-Ray (EDX) spectrometer and Scanning Electron Microscopy (SEM), respectively. SEM observations indicated that the morphology of the film surface was modified from dense and uniaxial to disperse and dendritic with increasing the current density. The EDX analyses revealed the presence of Zn and O in the deposit.

Novel Inhalable Ciprofloxacin Dry Powders for Bronchiectasis Therapy: Mannitol-Silk Fibroin Binary Microparticles with High-Payload and Improved Aerosolized Properties.

Non-cystic fibrosis bronchiectasis (NCFB) is a chronic respiratory disease associated with the high morbidity and mortality. Long-term intermittent therapy by inhalable antibiotics has recently emerged as an effective approach for NCFB treatment. However, the effective delivery of antibiotics to the lung requires administering a high dose to the site of infection. Herein, we investigated the novel inhalable silk-based microparticles as a promising approach to deliver high-payload ciprofloxacin (CIP) for NCFB therapy. Silk fibroin (SF) was applied to improve drug-payload and deposit efficiency of the dry powder particles. Mannitol was added as a mucokinetic agent. The dry powder inhaler (DPI) formulations of CIP microparticles were evaluated in vitro in terms of the aerodynamic performance, particle size distribution, drug loading, morphology, and their solid state. The optimal formulation (highest drug loading, 80%) exhibited superior aerosolization performance in terms of fine particle fraction (45.04 ± 0.84%), emitted dose (98.10 ± 1.27%), mass median aerodynamic diameter (3.75 ± 0.03μm), and geometric standard deviation (1.66 ± 0.10). The improved drug loading was due to the electrostatic interactions between the SF and CIP by adsorption, and the superior aerosolization efficiency would be largely attributed to the fluffy and porous cotton-like property and low-density structure of SF. The presented results indicated the novel inhalable silk-based DPI microparticles of CIP could provide a promising strategy for the treatment of NCFB.

How ownership structure affects bank deposits and loan efficiencies: an empirical analysis of Chinese commercial banks

This study explored how dramatic changes in ownership structure and operational technologies have influenced Chinese bank efficiency over the past decade. The study included an empirical analysis using 5 years (2011–2015) of operational data for 71 Chinese commercial banks. Two two-stage meta-frontier data envelopment analysis network models and multiple regression models were used to estimate and analyze impacts of variations in bank ownership structure. The main empirical results show that irrespective of deposits or loans efficiency, State-owned Banks (SOBs) have the highest technology and management levels. In contrast, City Commercial Banks should improve both technology and management levels, narrowing the gap with SOBs and Joint-stock Banks. The deposit efficiency of a bank was found to be mainly influenced by the nature of ownership (national shareholding ratio and the shareholding ratio of the domestic legal entities) and ownership concentration. The loan efficiency of a bank was mainly affected by the nature of ownership (the shareholding ratio of the foreign legal entities) and ownership liquidity.

Electrodeposition of Fe, Co, Mn and Their Alloys from Choline Chloride/Urea Based Deep Eutectic Solvents

Despite their industrial use for many decades, there is still desire and opportunity to improve the properties of soft magnetic materials. Applications such as hard drive write heads must attain higher saturation magnetization and low coercivity in order to maintain the ability to write to increasingly dense storage media[1]. Electrodeposition is often the favored fabrication method for such soft magnetic films due to its several advantages such as fast deposition rate, ease of growth on arbitrary shaped or recessed surfaces, and simplicity of orienting film anisotropy[2]. However, it is fairly limited in the number of different elements that can be deposited in high quality. In the past several years, room temperature ionic liquids, the current generation also being known as deep eutectic solvents (DES), have become an attractive alternative to traditional aqueous deposition baths. These solvents avoid the hydrogen generation that often reduces deposit quality and efficiency in aqueous baths, and enable the incorporation into the deposit of metals with more negative deposition potentials than are viable in aqueous baths. Despite significant progress in literature on the electrodeposition of various material from DESs, their suitability for improving characteristics of magnetic films is relatively little-studied[3]. This work studies the deposition behavior of Fe, Co, and FeCo ferromagnetic alloys from the DES formed of a 1:2 mole ratio of choline chloride and urea (ChCl-urea). Deposited films are then characterized to determine their morphology, crystal structure, and magnetic properties. Mn, which has been predicted to increase the magnetization of FeCo materials[4], has been incorporated to form a tertiary FeCoMn ferromagnetic alloy, and its effects of the film properties are determined. Initial voltammetric studies (Fig. 1) and depositions show that deposition of Fe-Co from ChCl-urea proceeds by induced codeposition, wherein Fe deposition is promoted by Co, allowing the alloy film to be obtained at potentials less negative than required for pure Fe. Increasing the deposition overpotential leads to higher Fe content in the film, and a mass transfer limit is quickly reached for both depositing species at which the film composition no longer depends on overpotential. Composition of the deposit is easily controlled by changing the metal ion concentration in the bath. Mn is also found to deposit by an induced codeposition mechanism with Fe-Co, wherein it can be incorporated into FeCo films in small amounts at an underpotential to pure Mn electrodeposition. The incorporation of Mn in alloy films is constant at around 3 wt. % when depositing in underpotential conditions. The effects of several deposition conditions including temperature, metal ion concentrations, and bath agitation, were studied and will be discussed in the presentation.

Electrodeposition of Soft Magnetic Fe-Co and Fe-Co-Mn Films from Deep Eutectic Solvents

While electrodeposited magnetic alloys have been used for decades in hard disc drives and other micro-electro-mechanical systems (MEMS), these alloys have evolved many times for improvement in magnetic properties such as low coercivity and high magnetic moment[1, 2]. Despite their wide industrial use, there is still a desire and opportunity to further improve the properties of such materials[3]. Electrodeposition has been the preferred fabrication method for such soft magnetic films due to its several advantages such as low cost, fast deposition rate, easy scaling, flexibility of substrate geometry, and simplicity of film anisotropy control[4]. In the past several years, room temperature ionic liquids, the current generation also being known as deep eutectic solvents (DES), have become an attractive alternative to traditional aqueous deposition baths. These solvents avoid the hydrogen generation that often reduces deposit quality and efficiency in aqueous baths. It therefore provides some opportunities to tune the magnetic properties of deposited materials by incorporating additional elements with more negative deposition potentials than are viable in aqueous baths, for example Mn[5]. Despite significant progress in literature on the electrodeposition of various material from DESs, their suitability for depositing magnetic films is relatively little-studied[6]. This work studies the magnetic characteristics of FeCo alloys electrodeposited from the DES formed of a 1:2 mole ratio of choline chloride and urea (ChCl-U). In addition, a tertiary FeCoMn film has been electrodeposited from ChCl-U, and its magnetic properties have been studied. Both FeCo and FeCoMn films electrodeposited from a variety of conditions have been shown by VSM measurements to be ferromagnetic, and saturation magnetization and coercivities have been extracted from hysteresis loops (Fig. 1). The incorporation of small amounts of Mn (~2%) has been predicted to slightly improve the magnetization of FeCo films, however larger amounts dilute the ferromagnetic coupling within the film. Coercivities on the order of a few hundred Oersteds are observed. The film morphology is found to be relatively smooth for thin deposits, however cauliflower-like film growth is observed after long deposition times. Films contain micro-scale cracks in most cases. The detailed results on electrodeposition, x-ray diffraction, as well as other characterizations will be discussed.

Effect of Fe and Co co-deposited separately with Zn-Ni by electrodeposition on ASTM A624 steel

A comparison between the Zn-Ni, Zn-Ni-Fe and Zn-Ni-Co coatings was performed in this study. The co-deposition process was obtained by electrodeposition on ASTM A624 steel using sulphate baths in acid media and low current density. The characterization of the coatings by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP OES), Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD) and Anodic Linear Sweep Voltammetry (ALSV) allowed a detailed analysis of the phases formed and its amounts in the coatings, which enabled to verify the influence of the Fe and Co co-deposited separately with Zn/Ni. The co-deposits showed different characteristics in relation to the deposition efficiency and film thickness, in addition of the topography and surface roughness, which were measured by a confocal optical microscope and of the hardness determined by an ultra-microhardness tester. Finally, the corrosion tests analyzed by open circuit potential, potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) determined the corrosion characteristics of each co-deposit in saline solution. Results showed that Zn-Ni-Co was superior to the others co-deposits in relation to the deposit efficiency and corrosion protection, in contrast, the Zn-Ni-Fe coating showed uniformity and the greater compaction of the surface grains, resulting in lower roughness and higher hardness between the co-deposits studied.

Global and local transport properties of steady and unsteady flow in a symmetrical bronchial tree

The branching structures and bifurcation flows in human lung are crucial factors for the functioning of the respiratory system. In this paper, both steady and unsteady flow in a symmetrical bronchial tree have been investigated, and the global and local transport properties are explored by fractal geometry and computational fluid dynamics method, respectively. Firstly, total flow properties for steady laminar flow and pulsatile flow in a fractal tree-like network are derived, and the global fluid dynamics behavior under volume constrain is discussed accordingly. And then, a mathematical model is developed for the steady and unsteady gas flow as well as gas-particle two-phase flow in a four-generation bifurcation in order to study the local transport characteristics of bronchial tree. The results indicate that the critical successive diameter ratio for the first few generations is below the prediction of Murray’s law while small airways follow Murray’s law. It has been also shown that the asymmetrical and non-uniform flow distribution can be realized through a symmetric branching structure with increased Reynolds number. The asymmetric ratio is found to be scaled with the Reynolds number as χ∼Re0.00124 in the steady respiratory condition. The effect of Reynolds number and respiratory frequency on the flow distribution and particle deposit efficiency are studied for different respiratory conditions, which show that the particle deposit efficiency can be increased with increased Stokes number. The present work is important for the morphology of the bronchial tree and understanding the physical mechanism of the bifurcation flow.

STRENGTHENING FINANCIAL SYSTEM STABILITY THROUGH ENHANCING INTERMEDIARY FUNCTION AND EFFICIENCY OF BANK PEMBANGUNAN DAERAH (REGIONAL DEVELOPMENT BANK)

This paper analyzes the function of the regional development banks (BPD) as an intermediary institution using the loan to deposit ratio (LDR) and Bank Indonesia Certificate to deposit ratio (SDR) and efficiency performance with data envelopment analysis (DEA) approach with data during 2006-2007 covering 26 BPD in Indonesia. The result of study indicates that the regional development banks do not play its optimal role as the intermediary institution and efficiency performance do not achieve the level of maximum 100 persen. For getting the optimal function of banking intermediary and promoting better efficiencies, BPD needs to design some steps of the grand strategy that can be developed in the future, that is: the limitation of funds placed by BPD in Bank Indonesia Certificate notes, inter BPD networking, focus on market segmentation, diversification source of funds, and creating local credit guaranting institutions. Keywords: bank efficiency, bank intermediary, loan to deposit ratio (LDR), SBI to deposit ratio (SDR), data envelopment analysis (DEA)

Simultaneous recovery of Zn and MnO2 from used batteries, as raw materials, by electrolysis

High purity electrolytic manganese dioxide (EMD) is the main raw material used for manufacturing of zinc and manganese based portable batteries (alkaline with manganese AlMn and zinc carbon Zn–C). Lately, due to the progressive depletion of MnO2 natural resources, the quantity of artificially electrolytic produced MnO2 has started to increase to satisfy the demand.This paper describes an electrolytic process for the simultaneous production of the following components:•MnO2, with the same quality as the one used in portable batteries;•commercial quality zinc, resulted from Zn and Mn sulphate solution obtained from reductive acid leaching (see Buzatu et al., 2012 paper). The sulphate solution is a by-product of used portable batteries crushing process.The electrolysis process was conducted in a specialized laboratory facility. The study was particularly focused on the following electrolysis process parameters:•evolution of MnO2 deposit efficiency based anodic current density;•sulphuric acid concentration influence on zinc metal and MnO2 deposit. The results have allowed the identification of optimal conditions for electrolysis.
