Abstract:

A new low air-entraining polycarboxylate superplasticizer (denoted as L-PCE) was synthesized by using oxirane/epoxypropane (denoted as EO/PO) block-polyether as one of monomers. The molecular structure of EO/PO block-polyether monomer was characterized by proton nuclear magnetic resonance spectroscopy (denoted as 1H NMR). The pore parameters, workability, and compressive strength of the concrete added with L-PCE were compared to that added with conventional polycarboxylate superplasticizer (denoted as G-PCE) or the G-PCE compounding with defoaming agent. The results demonstrate that the air en

Abstract:

The prerequisite to synthesize PCE was to prepare new macromonomers with controlled molecular mass, adjustable hydrophilic-lipophilic groups, long-chain alkyl groups, and large terminal hydroxyl groups as well. Structural modifications in the molecular scale of polycarboxylate superplasticizer (PCE) would lead to changes in properties of dispersion and water retention as well as enhancement in the compatibility of Portland cement and so on. This paper reviewed recent developments from synthetic methods of macromonomers as the initial step of production of PCE, PCE at room and elevated temperat

Abstract:

ABSTRACT Two tetrachlorethene (PCE)-dechlorinating populations, designated strains BB1 and BRS1, were isolated from pristine river sediment and chloroethene-contaminated aquifer material, respectively. PCE-to-cis-1,2-dichloroethene-dechlorinating activity could be transferred in defined basal salts medium with acetate as the electron donor and PCE as the electron acceptor. Taxonomic analysis based on 16S rRNA gene sequencing placed both isolates within the Desulfuromonas cluster in the δ subdivision of the Proteobacteria. PCE was dechlorinated at rates of at least 139 nmol min−1 mg of protein−

Surface plasmon coupled emission (PCE) was demonstrated using Copper (Cu) as metal film and Rhodamine B (RhB) dye doped Poly Vinyl Alcohol (PVA) as dielectric layer coupled to a hemicylindrical prism in Reverse Kretschmann (RK) configuration. Emission directionality was observed due to PCE and the dielectric layer thicknesses highly influence PCE emission steering. A correlation of emission directionality and the dielectric layer thickness was achieved. For dielectric with higher thicknesses, PCE tuning was also observed apart from emission steering.

PCE was rapidly adsorbed onto the TiO2 particles followed by its gradual degradation, and CO2 production started after a short lag time that corresponded to the adsorption phase. The rate of CO2 formation increased with increasing DO, TiO2 dosage and PCE concentration. There was no significant effect of initi

Two of these criteria—the criteria S (for state) and P (for process) introduced in Chapter 3—are defining criteria for any CDPS. The two remaining criteria—criteria PCE (for physical-computational equivalence) and U (for usability) introduced in this chapter—go further. CDPSs are classified as weak if they satisfy S and P but not PCE or U, robust if they satisfy S, P, and PCE but not U, and strong if they satis
