Synthesis of Water Soluble Hyperbranched Poly (amine-ester) as Corrosion Inhibitors for Steel

International Journal of Electrochemical Science, 2014
Encouraged by the excellent performance of dendrimers as scale inhibitors and anticorrisive coatings, we reasoned that dendrimers with properly designed structures might also be used as efficient water soluble corrosion inhibitors.

Multi-stimuli Responsive Composite for heavy metal detection Based on Mesoporous Silica and Polyelectrolyte Brush

International Journal of Electrochemical Science, 2020
Heavy metals are mostly non-degradable toxic substances, which are easy to be absorbed and enriched by organisms in the ecosystem, resulting in accumulation of the human body and difficult to be discharged.

Laser Metal Deposition of Aluminum Alloys 7075 and 5083 with the Addition of Volatile Alloying Elements through Powder Blending

Advanced Engineering Materials, EarlyView.
This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]

, 2004
The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...

Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

Advanced Engineering Materials, EarlyView.
The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.

The Marangoni flow of soluble amphiphiles

, 2013
Surfactant distribution heterogeneities at a fluid/fluid interface trigger the Marangoni effect, i.e. a bulk flow due to a surface tension gradient. The influence of surfactant solubility in the bulk on these flows remains incompletely characterized ...
