They play a key role in washing processes. The development of various surfactants （e.g., anionic, nonionic, cationic, zwitterionic, and silicone surfactants） and builders （inorganic, organic and polymeric builders）used in the detergent compositions are reviewed and their detergency performance and biodegradability are discussed. In the future, the development of the surfactants and builders used in detergent compositions should be based on economic and environmental considerations. The use of the eco-friendly surfactants and builders derived from inexpensive renewable resources （e.g., alkyl polyglucosides and bio-based polyesters） in detergent compositions is the developing trends in detergent industry.展开更多

With the central theme to summarize the global progresses in peritoneal carcinomatosis （PC） diagnosis and treatment, to draft the outline framework of international guidelines on PC treatment, and to formulate the future international collaborative research programs, this congress has set the new historical milestones in the global joint-effort to conquer PC. Major highlights of this congress are reported here.展开更多

The dynamic monitoring apparatus of fouling resistance was set up for the present experiments. The fouling behavio（s were examined under different factors including fluid velocity, hardness,alkalinity, solution temperature, and wall temperature. Asymptotic fouling curves varying with time were obtained. The fouling rate and asymptotic fouling resistance increased and the induction periods were shortened with the fluid velocity decreasing, hardness andalkalinity increasing, and solution temperature and heat transfer surface temperature increasing. Thecomponents of fouling that formed on the heat transfer surface included crystallization fouling and particulate fouling. The thermal performance parameter of fouling,ρfhf, varied from 380 to 2600 kg·W·（m^4·K）^-1, increasing with growing velocity and decreasing solution temperature, hardness or alkalinity. Furthermore, the thermal conductivity of fouling, λf, varied from 1.7 to 2.2 W·（m·K）^-1 .展开更多
