Constructing Ag-based photocatalysts by the incorporation of Ag(+) ions into metal/nonmetal oxides for removing organic pollutants is a recently developed strategy, but overcoming their own photocorrosion is still a tremendous challenge. In this work, an advanced Ag-based photocatalyst Ag2Ta4O11 is obtained by this strategy, which exhibits improved photocatalytic activity compared with Ta2O5 an...

This paper studies the provision of deposit insurance along with liquidation decisions without commitment in an economy with heterogenous households. The analysis separates control of the balance sheet of a failed bank from the provision of deposit insurance. We study the factors that determine orderly liquidation and the effects of this policy on the prospect of bank runs. We also study the pr...

This paper undertakes a simple general equilibrium analysis of the consequences of deposit insurance programs, the way in which they are priced, and the way in which they fund revenue shortfalls. We show that the central issue in analyzing deposit insurance is how the government will make up any FDIC losses. Deposit insurance premia matter only in so far as they affect the level of implied FDIC...

During the past decades, aqueous rechargeable batteries have been receiving much attention on account of merits cost efficiency, high safety, and environmental benignity. Compared to metal-ions (such as Li+, Na+, K+, Mg2+, Zn2+, Al3+ etc.) charge carriers in ion batteries, nonmetal not only form covalent–ionic bonds framework, but also act reversible redox centers. Moreover, advantages low cost...

We report on a study of the optical conductivity of single crystals of the high-Tc superconductor YBa2Cu4O8 in which superconductivity is suppressed by random substitution of Cu with Zn. The a-axis infrared spectrum, which is a direct measure of the charge dynamics in the CuO2 planes, is dominated by a bound state at ø120 cm21. This indicates that the low-energy electronic states are on the ver...

A tight-binding (TB) hamiltonian for calcium is built with a high precision parametrization technique based on density functional calculations of the energy bands and the total energy at various lattice volumes. The new set of TB parameters is appropriate to study phenomena under pressures as high as 20 GPa. Speci®cally, both the metal to nonmetal transition at 4 GPa and the structural transiti...

The type of prosthetic restoration used in implant rehabilitation greatly contributes to the recovery of masticatory function as well as quality of life in patients. Frameworks for implant-supported prostheses are typically made by casting metal or milling either titanium or zirconia. Recently, nonmetal, polymer-type materials were suggested as framework materials. Polyetherketoneketone (PEKK),...

Abstract We employ quantum molecular dynamic simulations to investigate the behavior of benzene under shock conditions. The principal Hugoniot derived from the equation of state is determined. We compare our firs-principles results with available experimental data and provide predictions of chemical reactions for shocked benzene. The decomposition of benzene is found under the pressure of 11 GP...
