In this paper, the preparation process of low viscosity light curing silicon oxide ceramic slurry and properties sintered samples were studied. By studying effects type concentration dispersant solid content powder on stability slurry, with viscosity, high good was prepared. The ceramics verified by compressive strength, shrinkage test SEM observation. results show that stearic acid as dispersa...

Resource extraction from the ocean comes with ecosystem-wide risks, including threats to its biota such as habitat forming corals that support elevated biomass and biodiversity. Despite catastrophic incidents like Deepwater Horizon oil spill (DWHOS) disaster occurred in 2010, offshore gas drilling continues occur around world. Previous work investigating toxicity of chemical dispersant used an ...

In this study, the physicochemical characteristics of crude oil, dispersant and oil-dispersant test systems their toxicities on representative marine organisms in a simulated ecosystem was assessed. Mechanically dispersed oil-in-water system (MDO) its water accommodated fraction (WAF) alone, combination with third generation (D) (Ecobest®), which gave rise to chemically (CDO) (CEWAF), as well r...

An anionic trypsinogen has been identified and isolated in a state of high purity from porcine pancreatic tissue and juice extracts. The anionic trypsinogen is present in large amounts and accounts for about half of the total potential tryptic activity. The kinetics of the conversion of the anionic trypsinogen to active enzyme is autocatalytic, yielding an anionic trypsin which is less anionic ...

Fish behaviours are often considered to be sensitive endpoints of waterborne contaminants, but little attention has been given to engineered nanomaterials. The present study aimed to determine the locomotor and social behaviours of rainbow trout (Oncorhynchus mykiss) during waterborne exposure to single-walled carbon nanotubes (SWCNTs), and to ascertain the physiological basis for any observed ...

Nanoparticle suspension and forming are important areas. In this paper, the stability and rheology of A1203 nanoparticle suspensions at different dispersant concentration, suspension pH, and solids loading were studied. The most desirable suspension conditions were 7.5-9.5 for pH and 2.00-2.25 wt% of A1203 for poly(acry1ic acid) (PAA) dispersant. 45.0 vol% A1203 solids loading can be achieved w...
