As the living standard improves, disposable sanitary and household paper requires not only softness or easy to fluff in a dry state, but also good antibacterial property. In this study, series of alkyl quaternary ammonium salts (AQAS), kinds antibacterial-debonding agents, were synthesized by using two-step process. The SN2 nucleophilic substitution reaction was designed between triethanolamine...

The challenges for scientific journals at the beginning of 21st century are exciting but beginning of 21st century are exciting but formidable. In addition to reporting faith-formidable. In addition to reporting faithfully new knowledge and new ideas, each fully new knowledge and new ideas, each journal, or at least all those aiming for a journal, or at least all those aiming for a general read...

Research has been conducted toward developing technology for co-firing of coal with municipal solid waste (MSW) in order to reduce emissions of chlorinated organic compounds, particularly polychlorinated dibenzo-p-dioxins and furans (PCDDs and PCDFs). Previous benchand pilot-scale research has shown that presence of SO2 can inhibit the PCDD and PCDF formation, and suggested cofiring high-sulfur...
