Arbitrage and liquidity are interrelated. Liquidity facilitates arbitrageurs’ trading on deviations from the law of one price. However, whether arbitrage opportunity leads to an increase or decrease in liquidity depends on the cause of the deviation. A demand shock leads to greater liquidity,...

The present study examines the effects of oil price on white precious metal returns by using quantile-on-quantile regression proposed by Sim and Zhou (2015). In this study, we mainly focus on the returns of three white precious metals, which include palladium, silver, and platinum. The study is...

To find out if gold remains to be unlinked with the crude oil market after the 2008 financial crisis, we investigated how long-run price linkages and price causalities among crude oil and gold markets changed before and after the crisis. To have a good reference, we also tested the same issue...

Seasonality phenomenon based on superstitions and beliefs is still an interesting topic to investigate. Other belief which may become interesting topic to investigate is Chinese Zodiac. Chinese Zodiac Effect is based on a myth that each year circumstance will be affected by every underlying year...

Much academic and investor analysis and commentary sees the four main precious metals as a single market, integrated and to some degree with each metal a substitute for the other. This proposition, which can be explicit or implicit can be challenged on economic grounds and on statistical...

Trends and prospects of international major commodity prices. In 2012, the international commodity markets have seen declining prices, especially during the first half of the year, with some improvement mainly in the last quarter. On the whole, most of major commodity prices declined, following...

We investigate whether proxies for mood play a role in the pricing of gold, silver, platinum and palladium. Using several mood proxies derived from weather and biorhythms factors, our tests suggest some individually significant relationships, but with very low overall explanatory power. We...

I test for the presence of asymmetric volatility in the Platinum and Palladium futures markets. My investigation is based on a variant of the heterogeneous autoregressive volatility model, using daily realized variance and return series from 2004 through 2009. I find that a decline in oil...

Platinum (Pt) deposited Nafion® membrane, as cathode, was prepared by impregnation reduction method using nonionic surfactant and their catalytic activity was characterized for hydrogen evolution reaction in a PEMWE (Polymer Electrolyte Membrane Water Electrolyser). The average diameter of the...

Platinum is increasingly used intentionally and non-intentionally in several applications. This has raised the concern about its future resources, emissions and losses during its life cycle. On the one hand, increasing platinum emissions might affect human health. On the other hand, the...

Microbial fuel cells (MFCs) hold great promise as an alternative for direct biochemical energy extraction from both biomass and wastewater. However, the commercialization and scaling-up of MFCs is not completely feasible, due to the high price of platinum (Pt) as a cathode catalyst. In this...

Platinum counter electrodes in DSSC are generally prepared by thermal reduction method. Poor control over Pt particle size, agglomeration and bad adhesion to the transparent conducting substrate, are some of the shortcomings affecting overall efficiency of the cell. In order to achieve better...

Deoxygenation of microalgal oil obtained by pyrolysis of microalgae was carried out for the production of hydrocarbon fuel from biomass by metal supported catalyst. Oleic acid was used as a model reactant to select an optimized catalyst. Effects of support, metal species, and metal loading on...

The emissions of nitric oxide and carbon monoxide from internal combustion engines generate a large impact on the environment and on people's health. Catalytic reduction of these species using platinum group metals has already shown significant potential for emissions control. Since catalysts...

The influence of Pt: Pd atomic ratios (1:2–1:8) on a carbon support upon its suitability as a cathode for a proton exchange membrane (PEM) fuel cell was evaluated at a constant membrane electrocatalyst loading of 0.15 mg/cm2. The results clearly demonstrated that the different Pt: Pd atomic...

A nano-scale Pt/C electrocatalyst for oxygen reduction in PEM fuel cells was prepared by alcohol-mediated reduction of the PtCl62− ion complex on the carbon Vulcan XC-72. The effects of various parameters, including the types of precursor and reducing agent and their concentrations, the...

The interaction of hydrogen with a platinum (111) cluster using the atom superposition and electron delocalization–higher binding ASED-TB quantum calculation method was studied. The metal surface was represented by a Pt cluster of seven layers. The effect of hydrogen on this metal substrate...
