Active Hydrogen for Electrochemical Ammonia Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
This review provides a comprehensive overview of the active hydrogen (H*) for electrochemical ammonia synthesis with particular attention given to the regulation of H* generation and consumption to suppress the competition of hydrogen evolution reaction and enhance the yield, selectivity, and Faradaic efficiency of ammonia.

Facile Synthesis of CuxS Electrocatalysts for CO2 Conversion into Formate and Study of Relations Between Cu and S with the Selectivity

open access: yesAdvanced Functional Materials, EarlyView.
Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Shooting Over or Under the Mark: Towards a Reliable and Flexible Anticipation in the Economy [PDF]

open access: yesInt. J. Comp. Anticipatory Syst. 5 (2000), 305-314, 2001
The real monetary economy is grounded upon monetary flow equilibration or the activity of actualizing monetary flow continuity at each economic agent except for the central bank. Every update of monetary flow continuity at each agent constantly causes monetary flow equilibration at the neighborhood agents.

An engineering economy expression analyzer

open access: yesComputers & Industrial Engineering, 1987
Abstract Students and practitioners of engineering economy are faced with the unenviable task of evaluating engineering economy expressions. If the example expression: 1000 ∗ ( P/F ,10,5) − 500 ∗ ( P/F ,6,20) + 100 ∗ ( P/A ,8,20) were solved manually, it would require three table look-ups to determine the values of
