This paper analyzes the degree of dynamic connectedness between energy and metal commodity prices in the pre and post-COVID-19 era, using the time-varying parameter vector autoregressive connectedness approach of Antonakakis et al. (J Risk Financ Manag 13(4):84, 2020). The results suggest that...

We examine the role of metals as economic inputs by using a production network model, calibrated for various countries using input-output (I-O) tables. Empirically, we employ local projections to study how metal shocks influence inflation, testing country-level heterogeneity in the sensitivity...

The paper examines the leverage effects and the spillover effects in the base metal cash and futures market. The study also attempts to find the trend and the pattern of volatility clustering in the base metal markets of India. Further, the significance of the risk premium and the possible...

This paper investigates the diversification contribution of four main precious metals (i.e., gold, silver, platinum, and palladium) to a traditional portfolio of stocks, bonds, cash, and currencies, as well as the impact of the global financial crisis of 2008 on that contribution. We use a...

We assess the degree of connectedness among 16 metals that are critical for the production of clean energy technologies. These commodities are the constituents of the Energy Transition Metals (ETMs) price index maintained by the International Monetary Fund and comprise base, precious, and minor...

Despite frequent debates on commodity prices, limited attention has been paid to the processes, strategies and practices through which commodity prices are 'made' and related institutions and infrastructures. 'World commodity prices' are not passively 'discovered' but are outcomes of contested...

This paper examines the impact of spillover effects of energy transition metals on the Chilean economy. With the increasing demand for metals like copper and lithium due to the growth in renewable energies and electromobility, metal abundant countries like Chile must ready themselves to remain...

A novel measure of two classes of monthly commodity price uncertainty is constructed by applying mixed-frequency state-space modelling to forecasts of prices of six energy and fourteen metal commodities. Energy price uncertainty shocks are found to be contractionary for the world economy, while...

Metallic glass composites (MGCs) inherit the high strength of their glassy matrix and exhibit remarkable plastic deformation, hence have great potential in engineering applications. However, their preparation often relays on arduous component exploration or involves elusive technological...

This work investigates the effect of noble metal doping of MoSe2 on its adsorption of ammonia (NH3) gas. Pristine and noble metal doped MoSe2 structures are examined computationally using density functional theory (DFT). Clusters of timers of each Pt, Au, and Ag along with their combination are...

The influences of Ag and Co additions on the thermal stability and glass-forming abilities of twenty (Cu 46- x Zr 47 Al 7 Ag x ) 100 -y Co y ( x = 0, 1, 2, 3, 4 and y = 0, 0.5, 1, 1.5) alloys were systematically investigated by X-ray diffraction and differential scanning calorimeter techniques....

Rehabilitation of disused mine sites through stabilisation and botanical restoration is ecologically important, but metal transfer pathways to colonising wildlife are often less understood and have never been studied in marsupials. The rehabilitated Royal George tin mine tailings and...

A quantitative study of the surface composition of clean metallic and partially oxidized nickel exposed to oxygen was carried out employing X‑ray photoelectron spectroscopy (XPS). It was possible to resolve the previously unreported experimental peak structure of the metallic Ni 2p spectrum....

Applying thermal shock to carbon nanofibers (CNFs) allows the synthesis of small and evenly distributed catalytic nanoparticles (NPs) on its surface. In this study, metal oxide hemitubes (HTs) were synthesized by calcination of a sacrificial template based on CNFs, which were decorated with...

Until now, two-dimensional (2D) materials have shown outstanding potential for new devices based on their interesting electrical properties beyond conventional 3D materials. In recent years, a new concept, valley degree of freedom, has been studied for valleytronics in hexagonal 2D materials. In...

Chalcogenide glasses containing light alkali and Group 11 (Cu, Ag) halides MY (Y = Cl, Br, I) exhibit high ionic conductivity while their heavy alkali counterparts show promising properties for optical applications. The structural role of metal halides in chalcogenide glass networks remains...

Methylmercury (MeHg) is a prevalent toxic metal that readily modifies protein thiols. Reactive persulfides that play a role in redox homeostasis are able to inactivate this metal through sulfur adduct formation. Although humans are exposed to other metals that could consume reactive persulfides...

Lithium (Li) metal is considered as one of the most exciting anode materials for next-generation batteries because of its high theoretical capacity and lowest reduction potential. However, the uncontrollable dendrite growth associated with nonuniform deposition and huge volume change during...

Two-dimensional (2D) transition metal oxides (TMOs) are widely applied in various research fields. A reliable, general, and facile synthetic protocol applicable for a large variety of 2D TMOs is in emergent demand. S-S/Se-Se bonds widely exist in various metal sulfide/selenide layered crystals....

Heavy metal pollution and the potential for co-selection of antibiotic resistance in the environment is growing concern. However, clear associations between specific heavy metals and types of antibiotic resistance in river systems have not been developed. Here we investigated relationships...

Mg(NH2)2 -2LiH is one of the most promising hydrogen storage systems to be applied in hydrogen powered vehicles as hydrogen source. However, the synthesis of the main raw material Mg(NH2)2 is high-cost and time-consuming for the present technologies. Herein, we report a low-cost, time-saving and...
