fractional flow analysis confirms the advantages of surfactant alternative gas injection (sag) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of sag injection. in this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

HER photocatalysis: Choosing the right sacrificial agent! The cover art features alcoholic hole-scavenger requirements for photocatalytic hydrogen evolution. desired agent forms a relatively strong reducing radical and has an oxidized form that is not good electron acceptor, which might suppress process. Methanol, fulfilling these requirements, excellent choice. Moreover, CH2(OH)2 most efficien...

Often, H2 is produced photocatalytically at the expense of sacrificial agents. When a agent selectively oxidized, this allows coupling production with synthesis value-added organic compounds. Herein, it argued that conversion bioethanol into 1,1-diethoxyethane simultaneous increases economic viability photocatalysis and suggests semiconductor material most relevant for purpose.

by appearance of human societies, the spiritual needs of different individuals and societies to worship the creator and to donate in order to attain the health and to fulfill the wishes had caused them to erect the specific places for offering the sacrificial materials. this article is generally a brief study on the places to donate and offer the sacrificial materials to sacred places regarding...

An experimental study has been conducted on the effectiveness of two types of flow-altering countermeasures placed around a cylindrical pier under clear water condition, which include sacrificial piles and submerged vanes. Their arrangements follow the optimal configurations recommended in the published articles with some modification. The temporal evolution of maximum scour depth and its equil...

The present paper reports the use of an amphoteric copolymer, poly(diallylamine-co-maleic acid) (PDAMA), as a component of precursor layers (or sacrificial layers) for constructing free-standing layer-by-layer (LbL) films. A PDAMA-poly(styrenesulfonate) (PSS) film or PDAMA-poly(dimethyldiallylammonium chloride) (PDDA) film was coated on the surface of a quartz slide at pH 4.0 or 8.0, respective...
