چکیده
Abstract The molecular weight of the macromonomer has a great influence on performance Polycarboxylate Superplasticizer (PCE). PCE with different structures was prepared by using methylallyl polyoxyethylene ether (HPEG) weights 2400, 3000, 4000, and 5000. effects emptying time rheological properties cement paste concrete were investigated. test results show that paste, plastic viscosity ratio inverted slump have corresponding relationship: HPEG-5000 < HPEG-4000 HPEG-3000 HPEG-2400, HPEG-2400 best performance.

The complexation of trivalent lanthanides with a commercial polycarboxylate based concrete superplasticizer (Glenium® 51) is investigated using different spectroscopic techniques. Time-resolved laser fluorescence spectroscopy (TRLFS) in combination with a charge neutralization model is used to determine temperature dependent conditional stability constants (log β'(T)) for the complexation of Eu...

Low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle (LMWH-ISL-SLN) was developed for injective application. The morphological observation, particle diameter and zeta potential of LMWH-ISL-SLN were characterized using transmission electron microscopy (TEM) and a Malvern Zetasizer. Its entrapment efficiency (EE) and drug loading (DL) were determined by ultracen...
