Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

Policymakers and economic analysts have recently been concerned about potential inflationary pressures in the U.S. economy. Various economic statistics show the amount of unused productive resources has been diminishing. For example, the civilian unemployment rate has decreased and the capacity utilization rate of the nation’s factories has risen. If real output grows rapidly in the future, the...

Americans rely on emergency departments (EDs) to play a critical role in the health care safety net. But while the number of ED visits climbed significantly, the number of EDs dropped from 5,000 to 4,000 from 1991 to 2006. This synthesis examines the evidence on who uses EDs, the causes and consequences of overcrowding, and the cost of providing care in the ED. Key findings include: privately i...

Flexible real-time applications have predefined temporal limits within which they can operate. Real-time systems that support flexible scheduling need a mechanism to distribute spare capacity in a predictable way among the running applications with respect to the applications’ temporal limits and available system resources. This paper introduces a greedy algorithm for spare capacity distributio...

Batteries usually deliver mass loading-dependent electrochemical performance. Taking the selenium cathode as an example, Se reaction kinetics, utilization, and cycling lifespan seriously deteriorate with increased loading. Here, electrocatalytic reduction/oxidation strategy to realize high-Se-loading Zn||Se batteries fast kinetics high utilization is proposed. Specifically, synergetic effects o...

In the process of production, some of the inputs are fixed and cannot easily be changed, such as work hours of workers and hours of administrative or work, these types of inputs are fixed and others are variables. In this paper, by considering some inputs or outputs which are limited, their amounts must be integrated; this concept for integer data is extended. We show the importance of subject ...

This paper describes a laboratory experiment of electricity markets to study the effect of variable capacity utilization over market dynamics. Previous experiments have left out a potential source of cyclical behavior by assuming full capacity utilization. We run 12 experimental markets of the power generation sector, involving two treatments: a first treatment with fixed (full) capacity utiliz...

mil-53-cu has been synthesized hydrothermally and has been used for the first time for gas separation. mil-53-cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for ch4, co2 and h2 at 30 bar and 298 k. the high ch4 adsorption capacity of mil-53-cu maybe attributed to the high pore volume and large number of open metal sites. the high selectivity for ch4 over co2 (11.5) an...

The poly(ethyleneimine)-functionalized silica has been developed successfully as an effective adsorbent for the adsorption removal of Cu(II) ions from electroplating wastewater. The influences of pH, contact time and initial concentration of Cu(II) ions on the adsorption capacity and the effect of adsorbent dosage on the removal efficiency of Cu(II) ions from electroplatin...
