The present study deals with the analyses of direct reduction kinetics during hydrogen industrial iron oxide pellets. Various types pellets different percentage total content and metal oxides are examined. They reduced at temperatures pressure (700–1100 °C 1–6 bar) in atmosphere. behavior is described terms time to reduction, rate constant. All obtained results analyzed through employment a com...

This paper employs a difference-in-difference-in-difference approach to examine the emission reduction and foreign direct investment nexus in China. It combines firm-level dataset with target statistics at city-level. The findings indicate that stringent environmental regulation is associated fall of output firms general shrinking pollution-intensive industries cities heavy pressure particular....

Electrochemical studies of laccases from basidiomycetes, i.e., Trametes hirsuta, Trametes ochracea, Coriolopsis fulvocinerea, Cerrena maxima, and Cerrena unicolor, have been performed. Direct (mediatorless) electrochemistry of laccases on graphite electrodes has been investigated with cyclic voltammetry, square wave voltammetry as well as potentiometry. For all mentioned high potential laccases...
