WESTERN COAL TRANSPORTATION RATES FOR MINNESOTA USERS [PDF]
The objectives of this paper are to summarize the existing rates that determine the cost of transporting coal into Minnesota, to define the areas where there are no existing coal transportation rates and to provide a methodology for estimating the cost ...

Angewandte Chemie International Edition, EarlyView.By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

Enhancing the Performance of Aqueous Lithium‐Ion Batteries via N‐Methylpyrrolidone Additive
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Aqueous lithium‐ion batteries (ALIBs) have garnered significant attention in the field of energy storage due to their inherent safety. However, their practical application is severely constrained by a narrow electrochemical window and electrolyte crystallization at low temperatures.
