In recent years, the reduction of CO2 emissions and the stable supply of raw materials are two major issues for the steel industry. Low reducing agent operation in the blast furnace is required to reduce CO2 emissions in ironmaking. As a mean of realizing low reducing agent operation with using low-grade raw materials, ferro coke characterized by high coke reactivity is considered to be useful. Theoretical and experimental studies were carried out to verify the effect of the ferro coke usage on

To clarify the mechanism of the nucleation process in the soap-free polymerization of styrene in water, the polymerization process of styrene mainly at a temperature 46 degrees C was investigated on a molecular scale using an atomic force microscope (AFM) as well as a scanning electron microscope (SEM) and a dynamic light scattering apparatus (DLS). A cationic initiator was employed to make polymerized styrene adsorb electrostatically on the negatively charged mica plate with molecular-scale smo

Abstract The growth process of poly(isobutyl methacrylate) (PiBMA) particle prepared in soap-free polymerization using V-50 as an initiator was observed by atomic force microscopy (AFM) to clarify the growth mechanism. As a result, it was found that PiBMA particles were capable of growing by the adhesion of smaller particles, which generated freshly during the particle growth period, to their surfaces.
